Ceiling-Mounted Workstation Bridge Cranes
Capacities: 250 to 4000 lbs
Bridge Lengths, overall: up to 40’
Runway Spans: up to 45’
Height — Floor-to-Trolley Clevis: determined by ceiling structure
Spanco Ceiling-Mounted Workstation Bridge Cranes make the most of your existing building and production floor space. These systems:
- Hang from existing roof beams or trusses.
- Require no system support columns, no attachments to building columns, and no production floor space.
- Allow you to readily expand runway lengths and the number of bridges, and add links to monorail crane systems.
In addition to our custom engineered systems, we make pre-engineered kits that include everything but the hoist and sway bracing. All Spanco systems meet or exceed ANSI/ASME B30.11 standards for underhung cranes and monorails.
Trying to boost productivity without sacrificing space?
Spanco Ceiling Mounted Workstation Bride Cranes provide unlimited lifting coverage without sacrificing floor space or obstructing work areas. Our Ceiling Mounted Workstation Bridge Cranes eliminate the need for steel supports, making them a cost effective and ergonomic material handling solution.
Check out this case study about a John Deere dealership that replaced jib cranes and multiple forklifts with a Spanco Ceiling Mounted Bridge Crane. The ceiling mounted bridge crane allowed the dealership to free up space and introduce an efficient, multi-functional material handling solution that provides full access of movement to transfer loads from one station to another and extend coverage to the entire facility.
Options for Spanco Ceiling-Mounted Workstation Bridge Cranes
- Telescoping Bridges: Provide extended crane reach, allowing you to easily place parts into machinery or into a neighboring workstation. Telescopic bridge cranes also enable you to reach beyond a support column or under a mezzanine. Anti-kick-up wheels keep the telescoping bridge’s movement smooth, even when carrying up to 2000 pounds.
- Mixed Capacity Systems: Leverage system capability by specifying heavier capacity runways with multiple smaller capacity bridges. For example, a 2000-pound capacity runway can run two 1000-pound crane bridges or four 500-pound crane bridges.
- Tractor Drives: Motorize the bridge or hoist trolley on a Spanco Workstation Bridge Crane. Frequently used for loads of 1000-pounds or more. Tractor drives are also very helpful when transporting material into hard-to-reach areas where manual movement is difficult due to machinery, work tables, or other obstacles.
- Bridge Buffers: The buffers roll in the runway tracks between two crane bridges; keep the bridges apart so as not to overload the runway’s capacity.
- Intermediate Crane End Stops: Through-bolted stops installed at runway support centers to prevent more than one bridge crane from operating within a set of support centers.
- Double-Girder Nested Trolleys (Crab Trolleys): Increase the available lift height for low headroom applications. The hoist is nested between dual girders that form a box-shaped assembly that rises above a parallel set of connected bridges.
- Box Track: Festooning cables/hoses run in their own box track, typically positioned above the runway or bridge.
- Duct-O-Bar Electrical Connections: An alternative to festooning cable is the Duct-O-Bar 4-conductor electrical solid bar and brushes in conduit, which runs adjacent to enclosed track on runways or bridges.
End Stop Bumper: Resilient rubber bumpers increase impact resistance and are through-bolted to enclosed track.
Cable/Hose Trolley: Conveys flat cable power supply or round air hose. Four wheels ensure easy rolling. Pivoting clevis provides swiveling action for air hose. Standard trolley includes 3/8-inch max. air hose.
Festoon Section: Through-bolted on end of runway to allow stack-up of cable/hose trolleys. If festooning is a potential obstruction, use the Box Track and Duct-O-Bar alternatives outlined under the Bridge Crane Options.
End Truck: Smooth running connection between enclosed track bridge crane and runway tracks. Horizontal steel guide rollers on either end of the truck eliminate "crabbing action.”*
Hoist Trolley: Fabricated from precision-cut steel plate.*
Cable/Hose Clamps: Fitted at one end of runway and bridge. Flat cable 4 wire #14 AWG standard; 3/8-inch air hose optional.
- Ceiling-Mounted Systems: Either flush type or drop type with hanger rods. Includes clamps.
- Freestanding Systems: Flush type hangers; allow lateral and longitudinal adjustments.
Flat Cable Festooning Systems (4 wires #14 AWG): Supplied with all bridge crane systems; optional air hose systems available for various sizes. Festoon loops are 18 inches for bridges and 36 inches for runways.
Vacuum Hose Trolley: Free-moving trolleys with anti-kick-up rollers and Velcro straps to festoon vacuum hose for vacuum lifters.
*End trucks and hoist trolleys are: Trucks and trolleys are designed to ANSI B30.11 specifications for underhung bridge cranes. Both have large diameter, polyamide wheels equipped with anti-friction ball bearings. Steel wheels, zinc chromate plated finish, or bronze wheels with bronze guide rollers for “spark proof” applications are available.

Surface Preparation & Painting Procedures:
Spanco adheres to the standards of the Society for Protective Coatings (SSPC) for all product surface preparation. Prior to painting, all Spanco crane components are deburred and descaled using power tools equipped with sanding discs and wire wheels. Components are then washed utilizing a high-pressure/high temperature biodegradable degreaser solution. Parts are wiped clean and allowed to dry before the painting process. During painting, all components surfaces are coated with a quick drying, semi-gloss enamel, applied to a minimum dry-film thickness of 2 to 3 mils. A finishing coat is applied with a hot, airless, electrostatic spray paint system. Painted components are cured at air temperature.

- Inspect entire system annually or more frequently as defined by OSHA 1910.179. Inspection must be performed by a qualified person. Failure to do so may cause serious injury or death.
- This equipment, used as a crane, is not in any way designed for lifting, supporting, or transporting humans. Failure to follow specified load limitations can result in serious bodily injury or death.
- Applications involving vacuums, magnets, or other high impact lifters are considered severe usage (continuous service) and require special design considerations. Please contact factory for special design pricing.
- All systems with drop rod hangers must be laterally and longitudinally braced. Lateral sway bracing is furnished by others.
- Runway end stops must be aligned longitudinally so bridge hits end stops simultaneously.
- Do not locate splice joints more than 12” from the runway support centers when aligning plain track runways.
- Do not cantilever the runway track ends more than 12” beyond the runway support centers (not including festoon storage area) on plain track runways.
- Do not locate truss splice joints more than 48” from the runway support centers when aligning trussed track runways.
- Do not cantilever the trussed track runway ends more than 48” beyond the runway support centers (not including festoon storage area).
- To prevent trolley/end truck running out of the track, do not operate crane without end stop bolts firmly secured in place on each end of the bridge crane track and on each end of each runway track.
- Do not impact end stops at speed. Only impact end stops with caution.
- Never use end stops for repetitive bridge impacts.
- Do not skew bridge in runways.
- Do not operate hoist or crane if cotter pins are not in place and properly bent over on both sides of hoist trolley. Check regularly that the cotter pins are in place and securing the hoist on the hoist trolley.
