Height — Floor-to-Trolley Clevis: 10’, 12’, or 14’ heights are standard

Spanco Freestanding Workstation Bridge Cranes provide highly effective, cost efficient lifting and moving solutions, especially when:

  • You need overhead crane coverage for a large area––up to 40-feet wide and with unlimited length. With interconnected parallel systems, you can cover your entire building.
  • You rent or lease your building. Our bolt-together freestanding systems can be readily relocated, either within your plant or in an entirely new location.
  • You want to be able to easily expand or modify your overhead crane system.
  • Your roof support is inadequate for a Spanco ceiling-mounted bridge crane. Typically, a standard six-inch thick reinforced concrete floor is all that’s needed for our freestanding bridge cranes.

In addition to our custom engineered systems, we make pre-engineered kits that include everything but the hoist and anchor bolts. All Spanco systems meet or exceed ANSI/ASME B30.11 standards for underhung cranes and monorails. 

Looking to streamline your manufacturing process?

Spanco Freestanding Workstation Bridge Cranes are the perfect ergonomic solution for extending lifting coverage and providing full access of movement. Our Freestanding Workstation Bridge Cranes can replace multiple cranes with one fluid system for improved efficiency and productivity.

Check out this case study about a leading hydraulics facility that replaced dozens of manipulators with freestanding workstation bridge cranes from Spanco to cover their entire machining center—totally eliminating the need to transfer loads from one manipulator to another and drastically improving production time, worker safety, and overall efficiency.

Options for Spanco Freestanding 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.

Hanger Assemblies:

  • 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.
