Overview
Spanco Ceiling-Mounted Workstation Bridge Cranes make the most of your existing building and production floor space. These systems:
- Hang from existing building 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 transitions to monorail crane systems
In addition to our custom engineered systems, we make pre-engineered systems 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.
- Telescoping Bridges: Providing extended crane reach, telescoping bridges allowing you to place parts easily 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 2,000 pounds.
- Mixed Capacity Systems: Leverage system capability by specifying heavier capacity runways with multiple smaller capacity bridges. For example, a 2,000-pound capacity runway can run two 1,000-pound bridges or four 500-pound bridges.
- Tractor Drives: Motorize the bridge or hoist trolley on a Spanco Workstation Bridge Crane. Frequently used for loads of 1,000-pounds or more, tractor drives are 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 bridges, which prevent the bridges from overloading the runway’s capacity.
- Intermediate Bumpers: Through-bolted end stops installed at runway support centers prevent more than one bridge crane from operating within a set of support centers.
- Double-Girder Nested Trolleys (Crab Trolleys): Increasing the available lift height for low headroom applications, double-girder nested trolleys keep the hoist nested between dual girders, which form a box-shaped assembly that rises above a parallel set of connected bridges.
- Box Track: Festooning cables and 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 maximum 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 mounted or drop-rod mounted with hanger rods. Includes clamps.
- Freestanding Systems: Flush-mount 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 strap for festoon vacuum hose on vacuum lifters.
*End trucks and hoist 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 resistant” applications are available.
