What is a Jib Crane?

Ajib crane is an overhead lifting device featuring a horizontal arm (jib or boom) that protrudes from a vertical mast or support to lift and move loads within a fixed arc or circular area.

Jib cranes are commonly used inindustrial settings – such as warehouses, factories, and docks – often serving individual workstations or supplementing larger overhead cranes to maximize production and efficiency.

The jib arm supports a hoist (lifting mechanism) and typically can swing through an angle (from ~180° on wall-mounted units up to full 360° rotation on freestanding models) to cover a work area.

Historical Jib Crane Context

The concept of using a swinging arm for lifting dates back to antiquity –Ancient Greek and Roman cranes employed jib-like booms for building temples and aqueducts.

The first dedicated "jib crane" with arotating cantilever arm was developed around the 15th century in Italy, dramatically improving the ability to lift and position loads. With the Industrial Revolution and the advent of steam and electric power in the 19th–20th centuries, jib crane designs evolved in size and capability.

Modern jib cranes incorporate high-strength steel, efficient hoists, and slewing bearings, making them indispensable for safe, ergonomic material handling in countless industries.

Today, jib cranes significantly improve workplace safety and throughput. By handling heavy or repetitive lifts mechanically, they reduce strain on workers and minimize injury risks.

Components of a Jib Crane

The main components of a jib crane include:

• Mast/Pillar: The vertical column that supports the jib arm. On freestanding models, the mast is anchored to a concrete foundation (often with heavy-duty bolts and gussets) to provide stability. Masts are typically made of steel and must be strong enough to carry the load and any bending forces as the crane rotates.

• Jib Arm (Boom): The horizontal beam that extends from the mast (or wall). The boom carries the hoist and defines the crane's reach or span. It may be an I-beam or truss girder designed to handle bending stress. The jib arm on most models can swing through an arc (e.g. 180° for wall-mounted or 360° for floor-mounted) via a pivot at the mast.

• Hoist: The lifting mechanism travels along the jib arm to raise and lower loads. Hoists can be manual (hand chain), electric, or pneumatic, using a wire rope or chain to support the hook. The hoist is typically rated for a certaincapacity (maximum load) and lift speed. For example, lighter-duty jibs often use chain hoists for up to a few tons, whereasheavier loads may use wire rope hoists.

• Trolley: A carriage that mounts on the underside of the jib boom and from which the hoist is suspended. The trolley allows the hoist (and load) to move in and out along the length of the boom. Trolleys may bepush-pull (manual) ormotorized. They run on the flange of the boom's I-beam (or on a track, in some designs) and incorporate wheels or rollers. The trolley enables precise horizontal positioning of the load.

• Rotation Mechanism: The means by which the jib arm pivots around the mast or mounting point. In a freestanding or mast-type jib, a largeslewing bearing or bushing at the mast's top allows the boom to rotate (often a full 360°). Rotation can be free (pushed by the operator) or powered by a motor/gearbox on larger jibs. Wall-mounted jibs rotate around their wall bracket or hinge (typically up to ~180°). Many systems includerotation stops to limit the swing and prevent the boom from hitting walls or other equipment.

 

Types and Configurations

"When choosing a jib crane, it's essential to match your crane type to both your building structure and operational needs. Freestanding cranes offer great reach and lifting capacity but require heavy-duty foundations.

Wall-mounted jibs save valuable floor space but rely entirely on the strength of existing walls or columns.

Thinking through factors like how often you'll use the crane, what loads it'll handle, and even your workspace layout upfront helps guarantee safe, efficient, and trouble-free operations."

- Nathan Stout - Hoj Innovations Crane Engineer

Freestanding Jib Cranes

Freestanding jib cranes cranes have an independent vertical mast mounted to the floor (usually via a poured concrete footing) and a rotating boom. They can be installed almost anywhere – indoors on a factory floor or outdoors in a yard or loading dock – and even under a large overhead bridge crane to provide additional lifting coverage in specific areas.

Freestanding systems typically offer thehighest load capacities and longest spans of any jib type. For example, a heavy-duty freestanding jib may support spans up to ~50 feet and lift capacities of 10–15 tons, with a full 360° swing radius. This makes them ideal for large work areas, high-volume material handling, and servicing multiple workstations.

Freestanding Jib Crane Advantages

• They provide maximum rotation and reach.

• Do not rely on a building's structure.

Freestanding Jib Crane Disadvantages

• Generally, it is the most expensive and permanent type.

• Specially reinforced foundations and significant installation effort are required.

• Difficult to relocate after installation.

 

Wall-Mounted Jib Cranes

Wall-mounted jib cranes are affixed to an existing wall or building column, rather than a floor-mounted mast. The jib boom either cantilevers perpendicularly from the wall or is tied back to the wall with a tension rod for support.

The biggest benefit of wall-mounted jibs is that they requireno floor space or special foundation, making them space-efficient. They can be installed high on a wall near the ceiling to maximize clearance under and above the boom for tall loads.

Wall-mounted jibs typically havesemi-circular coverage (boom swing of 180° to 200°) since the wall obstructs full rotation. Capacities commonly range up to about 5 tons with spans of 8 to 30 feet – ample for many manufacturing or maintenance tasks.

These jibs are often used along the periphery of a shop, in individual bays, or as supplements to an overhead crane (allowing an operator to swing a load to a specific workstation).

Wall-Mounted Jib Crane Advantages

• They are very economical as they require no floor space.

• It can fold out of the way when not in use.

• It is ideal for maximizing vertical clearance and space efficiency.

Wall-Mounted Jib Crane Disadvantages

• Limited crane reach is restricted to areas near the mounting wall.

• It cannot slew a full 360° swing radius, typically limited to 180°–200°.

• An engineer must verify the structural integrity of the supporting wall or column.

• Generally suitable only for medium-duty tasks (a few tons maximum).

 

Articulating Jib Cranes

Articulating jib cranes feature a jointed boom with two (or more) swivel arms, instead of one straight beam. The boom has an inner arm (mounted to the mast or wall hinge) connected by a pivot joint to an outer arm. This design enables the jib to bend around corners or reach into confined spaces that a straight-boom jib cannot access.

The inner arm typically provides about 200° of pivot, and the outer arm can rotate up to 360° relative to the inner arm.

Articulating jibs are ideal for maneuvering loads in tight quarters—for example, reaching inside machinery, through doorways, or around columns to set a load in a precise location. Depending on the application, they can be floor-mounted, wall-mounted, or even ceiling-hung.

Standard capacities are in the lighter range (often 500 lbs to 1 ton maximum), and spans reach around 10–20 feet since larger or heavier-duty lifts become impractical with the double-arm design.

Articulating Jib Crane Advantages

• Greater flexibility and coverage in complex or constrained spaces.

• Allows operators to articulate the boom around obstacles.

• Enhances ergonomic handling, eliminating blind spots common to straight-boom jibs.

Articulating Jib Crane Disadvantages

• Typically limited to lighter loads (usually 500 lbs to 1 ton).

• Less rigid design restricts maximum capacity and span.

• The increased number of moving parts raises initial costs and ongoing maintenance needs.

Wall-Traveling Jib Cranes

The jib boom is mounted on a carriage that runs along a horizontal track on the wall (blue beams), allowing it to cover multiple workstations along the length of the building.

A wall-traveling jib crane combines features of a jib crane with a track system similar to an overhead crane. Instead of being fixed in one spot, the entire jib (boom plus its support) is mounted on rails on the side of a wall or building so it canslide horizontally to different positions along the wall.

As it travels, the jib arm can also swing through its arc (usually ~180° outward from the wall), giving extensive coverage of a large area parallel to the wall. This configuration effectively extends the working range of a jib crane beyond a single circular zone – one wall-traveling jib can service multiple work areas or stations lined up along a factory bay.

Wall-Traveling Jib Crane Use Cases

It is commonly found in long production bays, machining lines, or maintenance shops where a crane needs to move materials across a distance without obstructing the floor. Typical designs might handle loads from around half a ton up to 5–10 tons, depending on the rail and wall strength.

Wall-Traveling Jib Crane Advantages

• Eliminates the need for floor columns, keeping floor space unobstructed.

• Provides efficient linear coverage along extensive areas parallel to the wall.

• Capable of servicing multiple workstations with a single crane, reducing the need for various jib cranes.

Wall-Traveling Jib Crane Disadvantages

• It requires robust structural support for rail installation; the wall must support rolling crane loads.

• Usually custom-engineered to the specific facility, increasing installation complexity.

• Movement is limited strictly along the rail; boom reach is confined to one side of the wall.

 

Technical Specifications and Considerations For Jib Cranes

Several key specifications and design considerations are essential when planning or evaluating a jib crane.

Load capacity is crucial, as jib cranes come in capacities ranging from a few hundred pounds to many tons. Standard industrial jibs typically handle loads from around 0.5 to 5 tons (1,000–10,000 lbs). Always select a crane rated above your maximum expected load, including a safety margin for dynamic effects such as sway or shock loading.

Span (reach) refers to the length of the jib boom, determining how far out from the mast or wall the crane can lift loads. Typical spans vary from around 8 feet on smaller jibs to about 20–30 feet on larger models. A more extended boom provides greater coverage but may experience more deflection under heavy loads. Remember, usable hook reach is slightly less than the total boom length due to trolley end-clearances. Confirm that the boom length and rotation coverage can serve all necessary pickup and drop-off points within your work area.

Therotation range offered by jib cranes varies by type. Freestanding and mast-type jibs typically allow full 360° rotation, whereas wall-mounted models usually provide about 180° of swing. Articulating jib cranes have two pivoting segments—around 200° for the inner arm plus up to 360° for the outer arm. Ensure your chosen crane provides enough rotation coverage to reach required pickup points and, if necessary, install mechanical stops to prevent the boom from hitting nearby structures.

Height and clearance dimensions are critical to crane selection. The key dimension is the height under the boom, defined as the clear height from the floor to the underside of the jib boom. This dimension determines the maximum lifting height available for your loads and must accommodate the tallest item plus any lifting slings or hooks. Consider the mast or wall-mount height, ensuring it fits under your facility's ceiling or any overhead obstructions. Additionally, account for the headroom required by the hoist itself. Some specialized designs—such as drop cantilever jibs—allow for lower mounting to avoid overhead obstacles, while full cantilever designs maximize lift height if clear overhead.

Evaluate the crane'sduty cycle based on the expected frequency and intensity of use. Crane standards classify jib cranes according to their service level. Select a crane built for high-duty cycles if your application involves continuous heavy usage. For occasional or lighter use, a lower-duty classification may suffice. Operating cranes beyond their rated duty cycles can accelerate wear and reduce longevity, making appropriate classification essential for reliability.

Theinstallation requirements for jib cranes depend on crane type and load. Freestanding jib cranes need a substantial concrete footing designed to withstand not only the crane's static weight but also dynamic bending forces from a loaded rotating boom. Wall or column-mounted jib cranes require robust structural support—such as reinforced concrete or steel beams—capable of bearing the crane's loads without excessive deflection. It is advisable to consult a professional engineer to verify the structural integrity before installation. Additionally, anchor bolts and hardware must be installed following the manufacturer's guidelines to ensure safety and stability.

Considerations forpower and controls depend on crane size and application complexity. Smaller jib cranes often rely on manual rotation and chain hoists operated by hand, while larger or higher-capacity cranes commonly utilize electric hoists and motorized rotation or trolley travel. Electrification typically involves a festoon cable system running along the boom, with rotary electrical collectors at the mast for full rotation cranes. Control options include wired pendant push-button stations or wireless remote controls, allowing operators to safely manage crane operations from the floor. Always ensure an accessible emergency disconnect is installed for safety.

Lastly, theenvironmental factors of the crane's operating area must be evaluated. Outdoor or corrosive environments necessitate weather-resistant materials and finishes, such as galvanized steel or epoxy coatings, to prevent rust and corrosion. Hazardous locations with flammable vapors or dust require explosion-proof rated hoists, motors, and controls. Special features may be needed in extreme temperatures, high humidity, or dusty environments, including heated control enclosures or dust covers. Ensuring your crane's suitability for environmental conditions will maintain safe operation and extend its lifespan.

 

Safety Standards and Regulations

Operating a jib crane safely requires adherence to established standards and diligent maintenance. In the United States,OSHA regulations (e.g.,29 CFR 1910.179 for overhead cranes) apply to jib cranes used in general industry, and similar rules exist for construction.

These rules mandate practices such as regular inspections, operator training, and clear load rating indications. Additionally, theASME B30 series of safety standards provides guidelines for crane design, inspection, and use – jib cranes are covered underASME B30.17 (which addresses overhead and wall cranes and monorails).

Compliance with these standards helps ensure that jib cranes are installed and operated in a manner that minimizes risk.

Some critical safety practices and requirements for jib cranes include:

• Load Labeling and Limits: All jib cranes must be clearly marked with their maximumrated load capacity, and operators should never exceed those load limits.Overloadingis a leading cause of crane accidents. OSHA states that approximately80 percent of all crane upsets and structural failures result from exceeding the crane's rated capacity, making it fundamental to ensure loads remain within crane capacity and incorporate an appropriate safety factor.

• Inspections: OSHA and ASME guidelines call for regular crane inspections. This includespre-shift visual checks by the operator and more thorough periodic inspections by a qualified person. Any deficiencies (e.g. worn hooks or chain, cracked welds, malfunctioning limit switches) must be corrected before operation. It's recommended to keep aninspection and maintenance log for each crane, recording all inspections, repairs, and maintenance performed.

• Safety Devices: Jib cranes are required to have functional safety features. For example, hoists should havebrakes that can hold a load if power fails, and an uppertravel limit switch to prevent the hook or load block from being lifted into the boom. Larger jib systems often incorporate overload limiters or load indicators that warn or prevent the operator from attempting to exceed the rated capacity. These devices should be tested regularly and kept in proper adjustment.

• Operator Training and Operation: Only trained and authorized personnel should operate a jib crane. Operators must be familiar with the crane's controls, proper rigging techniques, and standardhand signals for communication. They should position themselves (and others) clear of the load's path – never allowing anyone under a suspended load. Smooth, controlled movements should be used to avoid swinging the load. If the jib has motorized rotation or trolley travel, the operator must stay aware of the boom's swing radius and any potential pinch points in the area.

• Maintenance: Routine maintenance is essential for safety and longevity. Follow the manufacturer's recommended maintenance schedule, which typically includes lubrication, replacement of worn parts, and bolt tightness checks. Critical components like hoist brakes, wire rope/chain, and electrical collectors should be inspected and serviced at specified intervals. Good maintenance practices prevent accidents caused by component failure and keep the crane compliant with safety standards. (Always use proper lockout/tagout procedures to immobilize the crane during maintenance.)

By incorporating these standards and practices – and fostering a safety-first culture – facility managers can ensure that jib crane operations remain incident-free. Regular audits of crane condition and operator procedures (against OSHA/ASME criteria) are advisable to maintain compliance and continuously improve safety.

 

Selection Criteria and Buying Guide

Choosing the right jib crane requires evaluating your needs and asking the right questions to suppliers. Key considerations include:

• Application Requirements (Load, Reach, Usage): Determine the maximum weight you will lift and the radius or area that needs coverage. These factors dictate the required capacity and boom length. Ensure the crane's rating comfortably exceeds your heaviest load. Also consider how often the crane will be used – for heavy daily production use, opt for a higher-duty model, whereas a lower-duty or manual jib might suffice for occasional/light use.

• Mounting Constraints and Crane Type: Assess your facility's layout and support structure. If you have open floor space and require full 360° coverage, afreestanding jib (with a floor-mounted mast) may be ideal. If floor space is limited or you have suitable building columns/walls, awall-mounted jib keeps the floor clear (though it only swings ~180°). An articulating jib offers added flexibility for maneuvering loads around corners or inside equipment. Discuss your workflow with the supplier to identify the best type for your situation – in some cases a jib crane may not be the best fit and a gantry or bridge crane could be recommended.

• Budget and Installation: Factor in the total cost of ownership – not just the crane price, but installation and long-term costs. Freestanding jibs usually require a substantial concrete foundation, which adds to project cost and time. Wall-mounted units are often cheaper to install but might necessitate structural reinforcement of the support column. Get clarity on what the vendor's quote includes: Does it cover delivery, foundation work, and installation? As a rule of thumb, smaller jibs may cost a few thousand dollars, while high-capacity or custom systems can be tens of thousands. Plan for eventual maintenance and inspection expenses as well.

• Supplier and Support: Choose a reputable crane supplier and verify that the jib crane meets applicablestandards (OSHA, ANSI/ASME). Inquire about warranty coverage and availability of spare parts. It's also wise to ask if the supplier provides services like on-site installation, operator training, and after-sale support (inspections, preventive maintenance, etc.). A vendor with strong engineering support can help ensure the crane is installed correctly and provide assistance throughout the crane's life. Ultimately, a slightly higher upfront cost may be justified by better support and a longer service life.

By considering these factors and questioning potential suppliers, you can make an informed purchase that meets your operational needs and fits your budget – with no surprises during installation or operation. The goal is to select a jib crane that balances capacity, coverage, and cost for your specific application, providing a strong return on investment.

In addition, choosing aturnkey jib crane supplier significantly simplifies your project. A single-source provider manages everything from consultation and design to installation and ongoing maintenance, streamlining communication and accountability. With one supplier owning all aspects of your project, schedules become more predictable, and accurate delivery dates can be confidently met.
