Beam Mounted Jib Crane

Work‑station‑focused beam mounted jib crane fastens onto certified building beams instead of ground‑set support pillars. Its rotatable boom handles onsite lifting and workpiece placement. Workers move goods conveniently, with zero floor‑space taken up by upright crane masts.

This configuration is suited to production cells, assembly stations, machine loading areas, maintenance bays, and other locations where repetitive handling is concentrated within a limited radius. The crane is engineered around the available support structure, required safe working load, boom outreach, lifting height, duty cycle, and the handling path of the load.

 

 

 

A beam mounted jib crane transfers the lifting and overturning forces generated by the boom into an existing load-bearing structure through an engineered mounting assembly. The system normally consists of a jib boom, a support bracket or mounting frame, a pivot connection, a hoist running track, and a lifting hoist. Depending on the application, the boom can be operated manually or equipped with powered slewing and hoist travel functions.

Unlike a pillar mounted jib crane, this design does not require a dedicated base foundation or a floor-fixed mast. It preserves ground-level access around machinery, fixtures, pallets, and operator walkways. Unlike a wall travelling jib crane, it is intended to serve a fixed handling zone rather than travel along a runway.

 

 

 

Existing-Structure Mounting

The crane is mounted to a verified steel column, structural beam, wall support, or purpose-designed bracket arrangement. This installation approach can reduce floor obstruction in areas where a foundation is impractical or where clear floor circulation is essential.

The supporting structure must be assessed for the complete crane load case, including vertical lifted load, boom self-weight, dynamic effects, horizontal forces, and the moment generated at maximum outreach. Mounting details are defined only after the structural interface has been reviewed.

Slewing Boom for Localized Coverage

The boom rotates around a fixed pivot to cover a sector of the workstation. A 180° slew configuration is appropriate where the operating area lies on one side of the supporting structure. The effective working envelope is determined by the boom length, the permitted rotation angle, hook approach, hoist dimensions, and any site obstructions.

Hoist Travel Along the Boom

An electric chain hoist, wire rope hoist, or manually operated hoist trolley can run along the jib boom according to the specified lifting duty and load requirement. This gives the operator controlled radial movement from the mounting point to the outer hook position.

Floor Space Remains Available

Because the beam mounted jib crane is supported from the building structure, the zone below the crane remains clear of a conventional freestanding mast. This is particularly relevant for forklift routes, workbench access, conveyors, and machine service areas.

 

 

 

Parameter	Typical Arrangement	Engineering Note
Rated capacity	125 kg - 3,000 kg	Final capacity depends on boom length, duty, hoist selection, and support capacity.
Boom outreach	2 m - 10 m	Longer outreach reduces available capacity and increases the support moment.
Slew range	Up to 180° in the illustrated configuration	The available angle depends on mounting position and obstruction clearance.
Mounting method	Structural beam, steel column, wall support, or engineered bracket	The supporting member requires load verification before installation.
Hoisting unit	Electric chain hoist, wire rope hoist, or manual hoist	Select according to load, lifting speed, duty cycle, and control requirement.
Boom rotation	Manual or powered, application dependent	Powered slewing is considered where load inertia, reach, or operating frequency warrants it.
Control	Pendant, radio remote, or application-specific control layout	Control selection should follow the handling sequence and site safety requirements.

 

 

A beam mounted jib crane is generally selected for repetitive, short-distance lifting at a defined point of use. Typical applications include:

• Machine tool loading and unloading
• Assembly and sub-assembly workstations
• Die, fixture, and component handling
• Maintenance operations in restricted bays
• Packing and dispatch stations
• Welding and fabrication cells
• Material transfer beside production equipment

For these applications, the value of the system is not simply its rated capacity. It is the ability to place lifting coverage where the operator handles the load, without introducing a floor-mounted crane structure into the working area.

 

 

 

A reliable jib crane specification starts with the handling task rather than the nominal load alone. The following information should be defined before the design is released.

1. Safe Working Load

State the maximum lifted load, including lifting attachments, below-hook devices, or fixtures. The safe working load must represent the complete suspended load, not only the workpiece weight.

2. Required Boom Outreach

Measure the distance from the mounting centerline to the farthest intended hook position. Allow for the actual load pick-up and set-down points, not only the geometric edge of the workstation.

3. Lifting Height and Hook Approach

Confirm the required hook height, the available headroom, and the lowest hook position needed for the task. Hoist body dimensions and trolley arrangement affect the usable lifting travel.

4. Duty Cycle and Operating Frequency

Specify lifts per hour, average lifting distance, operating shifts, and whether the crane is used for occasional handling or repeated production work. These factors influence hoist selection, motor duty, control method, and component sizing.

5. Support Structure Details

Provide drawings, dimensions, steel grade where available, member orientation, and the proposed mounting elevation. A beam mounted jib crane must not be attached to an unverified structure. The structure and connection must be assessed for the applicable crane reactions.

6. Working Envelope and Site Constraints

Identify the required slew zone, adjacent equipment, doorways, utility lines, access routes, and exclusion areas. The boom rotation limit and control position should be matched to the real operating environment.

 

 

 

Installation quality determines how effectively the beam mounted jib crane performs over its service life. The mounting brackets, fasteners, reinforcement plates, and connection geometry must correspond to the approved design. Site installation should confirm plumb, level, boom rotation clearance, hoist travel, power supply routing, and the operation of safety devices before the crane enters service.

A static and functional commissioning check should verify that the crane moves freely through its intended coverage area, that the hoist control is correctly oriented, and that the installed system conforms to the approved load rating and operating limits. Lifting operations must follow the applicable local safety regulations and the manufacturer's operating instructions.

 

 

For a defined lifting point, a beam mounted jib crane can provide more direct handling coverage than a larger area crane system. It places lifting capability close to the work, keeps the operator's movement within a controlled zone, and avoids the need for a floor-mounted mast where a suitable structural support is available.

The correct application is a fixed workstation with a verified mounting interface and a clear handling envelope. Where the lifting point must move along a building line, a wall travelling jib crane may be more appropriate. Where no suitable structure exists, a pillar mounted jib crane or a freestanding workstation crane should be evaluated instead.

 

 

What is the difference between a beam mounted jib crane and a pillar mounted jib crane?

A beam mounted jib crane transfers its loads into an existing verified structural support. A pillar mounted jib crane transfers its loads through a dedicated mast and foundation. The beam mounted arrangement preserves floor space, while the pillar mounted arrangement is used when the building structure cannot provide a suitable support point.

Can a beam mounted jib crane be installed on any steel beam or column?

No. The supporting member and its connections must be checked for the crane's vertical load, boom self-weight, dynamic forces, horizontal reactions, and maximum overturning moment. Installation is only appropriate when the structure can safely carry the approved crane load case.

What capacity and boom length are available?

The illustrated reference configuration covers 125 kg to 3,000 kg and 2 m to 10 m boom outreach. The actual capacity-outreach combination is customized because longer booms create greater bending moment at the mounting point. Final values require engineering confirmation.

Is 180° rotation standard for a beam mounted jib crane?

A 180° slew range is common for a jib mounted to one side of a workstation, as shown in the reference configuration. The final rotation range depends on the support location, building geometry, power supply arrangement, and required safety clearances.

Can the crane use an electric chain hoist?

Yes. An electric chain hoist is a common lifting unit for workstation handling. The hoist type, lifting speed, trolley arrangement, and control method should be selected based on the rated load, required lifting height, operating frequency, and positioning requirement.

Does the crane require a foundation?

A beam mounted jib crane does not use a separate floor foundation for a freestanding mast. However, the structural support and its mounting connection require engineering verification. The absence of a mast foundation does not remove the need to assess the supporting structure.

When should I choose a wall travelling jib crane instead?

Choose a wall travelling jib crane when the lifting zone must move along a building line or serve multiple stations in sequence. Choose a fixed beam mounted jib crane when one localized workstation requires repeated handling within a defined slewing area.
