Truck-mounted cranes, the powerhouses of heavy lift operations, are more like the go-to solution in the lifting world – mobile, flexible, and dependable. Hitched onto trucks intelligently, these cranes must be your ultimate choice when it comes to transporting heavy weights across diverse construction sites.

View Details

Well, tonnage capacity is at stake here – the maximum weight that these cranes can raise up. And don't doubt physics; correct tonnage is a prerequisite for smooth and secure operations. So, let's guide you through choosing tonnages that work well with the truck-mounted crane.

Establish What the Maximum Load Will Be

To begin with, find out the heaviest load that your crane will be subjected to. Calculate this mass taking into account attachments and rigging equipment so as to identify what your machine should lift as a routine. Would you rather overload it? This amounts only to machine wear-out and messiness of things if anything goes wrong. So, get it right always.

Working Radius and Height Consideration

Now let us discuss reach- working radius and height. How far can this beast stretch its arms, and how high can it reach? The operating radius is the distance from where the crane pivots to the center of the load.

And what is that? That’s essentially, how high you want to lift your load minus the distance from the ground. These numbers are critical. They influence how much weight that crane can support at different lengths as well as heights. There should be no mistakes in these calculations.

Understanding Load Charts

Load charts – your secret weapon. These charts outline lifting capacity at various boom lengths, radii, and angles. They must have briefings before any lifting operations. You have to check on them so that your crane does not become overloaded during any operation. No errors here – it’s about accuracy, ensuring your crane isn’t overwhelmed by anything that may come along while still on duty. Professionals differentiate themselves from amateurs in this regard.

Work Environment Consideration

In work settings, it’s not all about specs; it involves understanding the topography of an area, too. Check out wind conditions, look at the landscape, and feel the temperature. Your crane’s stability and performance are on the line. And do not forget about the site conditions – cramped spots, slopes, and tricky soil. Miss them, and you are having a compromised operation. We believe in smooth operation, not chaos.

The Duty Cycle and Frequency of Use

It is like understanding the rhythm of your job–duty cycle. How much the crane lifts or how long it runs – that is your duty cycle. If you are in for long-term benefits, continuous lifts call for a crane with some serious muscles i.e., higher tonnage.

But if it is more irregularly spaced, then less heavy weapons may be required for such intermittent lifts. Frequency also matters here as well; too much action means you want a crane built to last. It involves striking a balance between power and longevity.

Mobility and Space Limitations Evaluation

Now let us talk about mobility; these cranes aren’t just sitting there but they are moving around. Different job sites, different spaces – the crane’s got to adapt itself. Low clearances, tight corners – it’s like ballet; your crane has to know its moves. Therefore, choosing tonnage begins with understanding where it will be operating space-wise; get it right and you’ll have a shadow-like moving crane

Seek Guidance from Professionals

When working in this field it's crucial to seek advice from experts. Consult crane manufacturers, engineers, and experienced individuals in the construction industry. These individuals possess knowledge and insights gained through their real-world experience.

They can provide you with information regarding the size, suitable motor, and appropriate stabilizer technology. It's not about making guesses; it's about making informed decisions. Professionals don't rely on guesswork; they strategize.

To sum up, selecting the tonnage for your truck-mounted crane is not a one size fits all process. It requires planning, precision, and strategic thinking. From calculating weights to understanding the job site requirements it's about being sharp-witted, adaptable, and staying one step ahead. Your crane isn't a tool; it becomes your partner, in every heavy-lifting operation.

By ensuring you get the tonnage right you'll have an ally that will support you throughout all your heavy lifting endeavors.

Jib Cranes: Types, Uses and Maufacturing

Chapter One – What is a Jib Crane?

A jib crane is a category of lifting machinery characterized by an arm, or boom, that protrudes from the primary structure to enhance its reach. The lattice framework effectively minimizes added weight on the load. These cranes are perfect for smaller work environments and excel in repetitive lifting operations. They provide exceptional adaptability and versatility, capable of handling loads from as light as 250 lbs to as heavy as 15 tons.

Jib cranes are available in several different configurations, each designed to fulfill specific lifting requirements. The freestanding jib cranes are the most popular, offering flexible installation options in diverse settings. This design serves as the foundation for other variants, such as wall-mounted, ceiling-mounted, and articulating jib cranes.

Chapter Two – What are the Different Types of Jib Cranes?

The straightforward and robust design of jib cranes makes them ideal for installation in a wide range of industrial workspaces, manufacturing plants, shipping facilities, and warehouses. Their remarkable versatility and adaptability allow jib cranes to be customized for confined spaces, helping to alleviate the challenges associated with lifting, handling, and transporting heavy or awkward materials. Jib cranes are frequently used in conjunction with other types of overhead lifting equipment, such as gantry cranes, bridge cranes, or monorail systems, to maximize operational efficiency, flexibility, and material flow within a facility.

Like all material handling cranes, jib cranes are overhead lifting devices mounted on a horizontal beam, ceiling, column, or wall. They are commonly referred to as both jib cranes and boom cranes in the crane industry. The defining structure of the jib crane is the ‘jib’ or arm, which supports the lifting mechanism—usually an electric or manual hoist, chain hoist, or wire rope hoist—enabling the precise movement of loads within the crane’s working radius.

Jib Crane Types

Freestanding Jib Crane

Freestanding jib cranes are the most prevalent and versatile type, ideally suited for both indoor and outdoor applications. These industrial cranes can operate independently or in conjunction with overhead bridge cranes, monorails, or workstation cranes. Freestanding jib cranes can lift capacities ranging from a few pounds to several tons and commonly offer a full 360° rotational capability, greatly expanding their workstation coverage and application range.

Key advantages of freestanding jib cranes include flexible placement, substantial span, complete rotation, high load capacity, and the ability to serve as supplemental lifting solutions for production lines, assembly areas, and shipping docks. There are three main mounting configurations: base plate mounted, foundation mounted, and sleeve insert mounted. Selecting the ideal setup is based on load requirements, floor space, and existing building structure.

Base Plate Mounted

A base plate mounted freestanding jib crane is anchored to a base plate which is fastened to a reinforced concrete foundation with anchor bolts and supported by heavy-duty gussets for extra stability. This design permits the crane’s boom to extend over obstacles or existing machinery, and offers easy installation for retrofit or new construction projects. The base plate design is a popular choice for facilities needing versatile hoist placement and straightforward relocation options.

Foundation Mounted

A foundation mounted freestanding jib crane features a welded steel plate and a supporting mast embedded directly in a concrete foundation. This anchor system provides outstanding stability and durability, even under frequent and heavy-duty lifting operations. By eliminating gussets, foundation-mounted jib cranes are optimized for higher lifting capacities and rigorously demanding manufacturing or logistics environments.

Sleeve Insert Mounted

A sleeve insert mounted freestanding jib crane includes a steel sleeve installed in the initial layer of concrete, permitting the mast to be easily installed or replaced without demolition. With a second concrete layer encasing the sleeve, this design offers unique flexibility for expansion or facility reconfiguration, making sleeve insert mounting a popular choice for agile manufacturing and adaptable warehouse layouts.

Articulating Jib Cranes

Articulating jib cranes differentiate themselves from traditional straight-boom jib cranes by featuring both a pivoting boom and an articulating arm, which is connected by a rotating knuckle. This innovative design allows for superior maneuverability, enabling precise positioning and smooth material handling around corners, through doorways, or into tight spaces where standard cranes would be limited. Articulating jib cranes can be mounted in several ways, including wall mount, floor mount, ceiling mount, or integration with bridge crane systems, allowing seamless workflow across complex production environments.

The dual-arm design of articulating jib cranes provides enhanced operational control: the main arm offers a 200° swivel, while the outer arm delivers a full 360° rotation—making it possible to reach into machinery, storage racks, or containers with ease. Typical uses include assembly lines, workstations requiring repetitive lifting, and environments with numerous physical obstructions or high-precision placement demands.

Wall Mounted Jib Cranes

Wall mounted jib cranes—also known as wall pillar, cantilever wall jib cranes, or wall bracket jib cranes—are engineered for maximum space efficiency. They do not require any floor or foundation space, freeing up critical workspace and allowing unimpeded traffic flow. Often installed as a supplement to a monorail crane or overhead bridge crane, wall mounted jib cranes are fitted close to the underside of the building’s lowest structural member, maximizing headroom clearance above and below the jib boom for taller loads.

These compact and highly adaptable lifting devices can be swung against the wall when idle, minimizing interference with production processes or equipment access. Offering boom lengths (span) from 8 to 30 feet and load capacities up to five tons, wall-mounted jib cranes are popular for fabrication shops, maintenance bays, and other restricted workspaces.

Wall-mounted jib cranes are available in two principal designs: cantilever and tie rod supported configurations.

Cantilever

The cantilever wall-mounted jib crane features a rigid boom supported directly by two mounting brackets on the wall or column. With the boom projecting perpendicular to the support surface, the full cantilever design maximizes vertical clearance, making it ideal for tasks requiring unhindered lifting close to ceilings or mezzanines. The robust construction ensures reliable load support and minimal deflection.

Tie Rod Supported

Tie rod jib cranes provide an economical and practical solution for hoisting applications along bays, walls, or columns, and as specialized supports for overhead and monorail crane systems. A tie rod-supported wall-mounted jib crane is fixed using two brackets: the lower bracket attaches to the boom and the upper bracket connects to the tie rod, distributing the load and allowing for a lighter, more cost-effective beam. Despite requiring slightly more headroom, tie rod supported cranes offer extended span and allow the hoist to traverse the full length of the boom, supporting loads throughout the beam’s travel.

Mast Jib Cranes

Mast type jib cranes are floor-supported cranes that derive additional stability from being tied off to the building’s top beams or trusses. Unlike foundation-mounted or base plate-supported jib cranes, mast jib cranes require minimal disruption to existing floors—often with no need for a special concrete foundation. This design makes mast jib cranes a highly cost-effective and quick-to-implement lifting solution for industrial facilities dealing with heavy and frequent loads.

Available in two main configurations—full cantilever and drop cantilever—mast jib cranes optimize either maximum headroom (full cantilever) or position the boom at a specified lower elevation (drop cantilever) based on process needs. These cranes offer a span range from 10 feet up to 40 feet, lifting capacities as high as ten tons, and a full 360° rotation, making them suitable for high-throughput material handling tasks in manufacturing, warehousing, and shipping.

With robust mast construction and adaptable mounting, mast jib cranes support production flexibility and long service life, even in demanding heavy-duty settings.

Portable Jib Cranes

Portable jib cranes are engineered for maximum mobility, offering a unique advantage for operations requiring on-demand lifting capabilities at multiple locations within a facility. These lightweight and mobile cranes are mounted on a moveable base—typically fitted with caster wheels or designed to be relocated by forklift—enabling a single operator to safely transfer heavy materials, components, or parts without permanent installation.

Usually rated for lighter lifting applications, portable jib cranes manage loads of up to half a ton while emphasizing ease of movement and positioning. Their compact footprint and flexible core construction make them ideal for maintenance shops, machine assembly, and production tasks that demand frequent setup changes or temporary lifting solutions. Safety features such as locking wheels, stabilizing outriggers, or counterweights are commonly integrated to ensure load stability and operator safety while in transit or operation.

Hydraulic Jib Crane

A hydraulic jib crane is a specialized type of portable jib crane equipped with a reliable hydraulic cylinder to raise and lower the jib boom efficiently and smoothly. The hydraulic lifting system may be powered by battery or manual hand pump, allowing precise control when maneuvering heavy loads. This enhanced lifting mechanism offers more consistent performance compared to manual cranes, and is commonly used for automotive repair, small-scale manufacturing, or any application where variable lifting heights and reduced operator effort are important.

Hydraulic jib cranes can handle up to one ton when the boom is retracted, and up to 500 pounds when fully extended. In addition to the mobile floor-mounted variant, hydraulic jib cranes are also available in stationary configurations with a 360° degree rotational range. These cranes can be paired with an electric hoist or hand pump system for material handling versatility and ergonomic operation.

Wall Traveling Jib Crane

A wall traveling jib crane is designed to move along horizontally mounted rails or tracks fixed to the walls or building supports, optimizing floor space and streamlining lateral load movement within restricted work areas. Wall traveling jib cranes are prominently used in machine shops, assembly lines, maintenance areas, and warehouses where maximizing the handling envelope and minimizing production interruptions are key objectives.

With load capacities ranging from 0.5 to 10 tons and customizable spans, wall traveling jib cranes deliver precise vertical and horizontal movement. Their ability to work in tandem with other cranes or serve as auxiliary lifting equipment enhances overall plant productivity, material flow, and safety. As a flexible lifting solution, wall traveling jib cranes can be engineered to fit specialized work cycles and non-standard building layouts.

Ceiling Mounted Jib Cranes

Ceiling mounted jib cranes solve space-constraint issues by offering high-capacity lifting without occupying valuable floor space. Suitable for busy production floors, assembly stations, or high-density storage environments, these cranes can be installed as standard straight-boom models or articulating types for enhanced maneuverability. Ceiling mounted jib cranes are available with either fixed or rotating mounts, giving plant managers flexibility in how loads are moved between workstations or process cells.

Typically rated for loads up to one ton and spans to 16 feet, ceiling mounted jib cranes are purpose-built for applications demanding broad coverage without the need for obstructive floor supports. Their 360° pivoting range allows for versatile operation in tight or irregularly shaped facilities, contributing to safer, more efficient, and more productive material handling processes.

Workstation Jib Crane

Workstation jib cranes are tailored for repetitive, small-scale lifting operations and are essential for boosting productivity and ensuring operator safety in environments such as assembly lines, packaging facilities, or repair shops. These ergonomic cranes facilitate fast, precise, and effortless manipulation of workpieces, components, or subassemblies, and can easily transfer loads between adjacent workstations or process areas.

Most workstation jib cranes are freestanding, with standard heights of around 12 feet and offering full 360° rotation. Mounting plates differ depending on required lifting capacity: smaller models use square plates with gussets for stability, while heavy-duty versions incorporate hexagonal plates for increased strength. Workstation jib cranes support varied load requirements, promote lean workflow, and are easily customized with different hoist options or below-the-hook attachments for specialized tasks.

Truck Mounted Jib Cranes

Truck mounted jib cranes are among the industry’s most versatile and mobile lifting solutions, widely used for construction, utility service, roadside recovery, and heavy equipment maintenance. These cranes are built from high tensile strength steel and are securely bolted to the bed of a truck or trailer, transforming a standard vehicle into a mobile lifting platform for off-site or remote work environments.

Leading Manufacturers and Suppliers

Chapter Three – What are the Components of a Jib Crane?

Jib cranes feature a straightforward yet highly effective design, primarily consisting of a boom and mast, with a range of engineered components to maximize material handling efficiency and operational safety. Depending on their industrial application, jib cranes may incorporate motorized trolleys, advanced electrical controls, and load-handling attachments, while some are operated manually using wire ropes, industrial-grade levers, or chains. Designed for versatility, jib cranes can handle various load weights and are often used in workshops, warehouses, manufacturing plants, and assembly lines.

The design and construction of jib cranes involve numerous critical factors, such as load capacity, span, and rotation range, each aimed at optimizing productivity while reducing workplace injury risks. Jib cranes start with a fundamental, durable structure, but are systematically engineered and customized with additional crane accessories to accommodate diverse lifting applications, including repetitive lifting, precise positioning, and integration with overhead crane systems for enhanced material movement.

Key Structural and Functional Jib Crane Components

Mast Components

The mast is the robust vertical pillar that supports the load-bearing elements of a jib crane. In most freestanding and floor-mounted jib crane systems—excluding wall-mounted, wall-traveling, column-mounted, or ceiling-mounted models—the mast is fabricated from high-strength structural steel and securely anchored to the facility's foundation or walls to ensure stability and long service life. The mast's design provides sufficient clearance above the workspace, preventing interference with other equipment or material flow, and can be customized for integration with existing bridge cranes or other material handling systems.

Jib cranes fitted with a mast are often cantilever types, enabling unobstructed 360° rotation and full utilization of the crane's operating envelope. Key differences in jib crane mast installation methods—such as base plate mounting, embedded sleeve, or direct foundation anchoring—are chosen based on load requirements and structural constraints to achieve maximum performance, reliability, and floor coverage.

Jib Crane Boom

The boom, also called the arm, is the principal horizontal weight-bearing component of a jib crane. It extends perpendicularly from the mast, a wall, ceiling, or column support to create the lifting radius. The boom supports the hoist and, in powered models, the electrical trolley, acting both as a track for horizontal movement and a strong lever for distributing weight. In some jib crane configurations, such as articulating jib cranes, the boom can consist of multiple tapered arms with flexible joints to maximize reach and precision in confined spaces.

Hoist in a Crane

The hoist is the core lifting mechanism mounted to the boom of a jib crane system that provides the vertical motion required for raising, lowering, and positioning heavy loads. The type of hoist selected determines the crane's lifting speed, load capacity, duty cycle, and suitability for specific applications. Common hoist types include electric chain hoists, wire rope hoists, and manual hoists with either levers or ratchets. Hoists can be powered manually for lighter jobs, while electric and air-powered hoists accommodate higher frequency operations, larger load capacities, and specialized material handling tasks.

Chain Hoist

Chain hoists leverage a high-tensile steel chain to lift loads, routed through precision sprockets and neatly collected in a storage container. Renowned for their cost-effectiveness and minimal maintenance, chain hoists are widely used in light-duty and medium-duty lifting scenarios. Available in manual, electric, or pneumatic configurations, they deliver dependable performance across a variety of industries. It’s important to note that while chain hoists maximize flexibility and mobility, their capacity is generally limited when compared to wire rope hoists—making them ideal for lighter industrial lifting applications, repair shops, and assembly operations.

Wire Rope Hoist

Wire rope hoists utilize a strong, flexible wire rope wound around a grooved drum to lift and move heavy loads—often exceeding 10 tons—at faster lifting speeds than chain hoists. Renowned for their smooth, quiet operation and superior load control, wire rope hoists excel in heavy-duty industrial settings such as steel fabrication, automotive assembly, shipyards, and foundries. They are ideal for demanding, repetitive lifting tasks that require greater capacity, high cycle rates, or specialized features such as variable speed control and advanced safety braking systems.

Manual Hoist

Manual hoists are used for occasionally lifting moderate to heavy loads where powered lifting speed is not essential or where an electrical supply is unavailable. They are available in both chain and wire rope designs. Operators use one chain to lift the load while a second chain (the hand chain) is pulled to operate the internal gears, rotating the load chain via mechanical advantage. Manual hoists offer a practical, budget-conscious lifting solution for maintenance, equipment installation, and low-cycle applications.

Lever Hoist

Lever hoists, also known as ratchet lever hoists or come-alongs, provide controlled lifting and pulling by engaging a hand lever rather than a continuous hand chain. These manual hoists are well-suited for vertical lifting, pulling, tensioning, and aligning heavy machinery in tight spaces or on construction sites. The operator moves the lever back and forth, incrementally raising or lowering the load with a ratchet-and-pawl mechanism—making them ideal for precision positioning work and load securement.

Crane Trolley

The trolley is the horizontal transport mechanism that carries the hoist along the length of the jib crane boom. Trolleys can be manual (push-pull), geared, or motorized, and are designed to support both wire rope and chain hoists with robust hooks or lifting lugs. The trolley’s travel flexibility enables efficient in-and-out material handling, optimizing workflow and reducing manual labor. A festoon system provides secure cable management, protecting electrical and control power lines as the trolley traverses, ensuring uninterrupted operation and safety.

Festoon System

The festoon system is a vital cable management solution that safely delivers electrical power and control signals to the trolley and hoist. Multiple festoon system types are available—including cable carriers on C-tracks, square rails, or traditional I-beams (the standard in many jib crane applications). Proper festoon system selection prevents cable wear, tangling, and accidental disconnection, ensuring reliable electrical connectivity and safeguarding the jib crane’s moving components. Festoon systems are especially important in cranes with extensive boom lengths, high-duty cycles, or complex powered trolleys and hoists.

Jib Crane Power Systems

Jib cranes are powered by either electrical (three-phase or single-phase) or pneumatic (compressed air) sources, depending on application needs and environmental considerations. Power or air lines are typically routed along the top of the mast and down the boom, providing energy to the hoist, trolley, and, in some designs, for boom rotation motors. Sophisticated push-button pendant or wireless radio remote controls allow for intuitive, safe operation—enabling crane operators to maneuver heavy loads precisely while remaining at a safe distance. Control stations may integrate variable speed, emergency stop options, and load monitoring for enhanced operational safety and compliance with OSHA standards.

Industrial users evaluating a jib crane system should consider their facility's available electrical supply, operational frequency, safety requirements, and the ergonomics of the crane's control interface to maximize efficiency, reliability, and worker comfort.

Rotation Stop

Rotation stops are engineered safety mechanisms that restrict jib crane rotation, preventing accidental collisions with nearby machinery, structural columns, walls, or facility infrastructure. In compact or crowded workplaces, fixed rotation stops—usually welded or bolted to the mast—define the movement limits of the boom. For added operational flexibility, adjustable rotation stops allow users to easily recalibrate the crane’s sweep to safely accommodate new layouts or changing equipment positions. This customization contributes to improved safety, crane longevity, and efficient space utilization.

Environmental Protection and Operating Conditions

Jib crane performance and longevity are strongly influenced by the installation environment. To protect crane components in harsh conditions, manufacturers offer specialized enclosures, weatherproof covers, galvanized structural steel for corrosion resistance, and explosion-proof electrical fittings for hazardous locations. For extreme temperature, dust, moisture, or chemical exposure, additional shielding and insulation can be specified. Careful consideration of the crane's environmental factors during the purchasing and installation process ensures continued safe operation, reduces maintenance needs, and preserves equipment value over time.

In summary, understanding the core structural and functional components of a jib crane—such as the mast, boom, hoist, trolley, festoon system, power supply, rotation stops, and environmental protection measures—enables facility managers, engineers, and purchasing agents to select, configure, and maintain material handling solutions optimized for safety, productivity, and cost efficiency. For those comparing jib cranes to other material handling equipment (such as gantry cranes, bridge cranes, or monorail systems), evaluating the specific features and customization options of each component is essential in achieving optimal results for your material lifting and workflow needs.
