Description
Ceiling Mounted Workstation Bridge Cranes are designed to accommodate limited work space situations by hanging from overhead building steel such as roof beams or trusses. Permanent installation is required.
- Capacities: 250 to 4,000 lbs.
- Bridge Lengths, overall: up to 40’
- Runway Spans: up to 40’
- Height — Floor-to-Trolley Clevis: determined by ceiling structure
Ceiling-mounted bridge cranes are great for applications with limited floorspace, facilities with large mobile equipment, and facility layouts that might change in the future. Ceiling-mounted systems also 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 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.
- 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: Many hanger options including flush-mount, drop rod, and wood joist connections mounted with hanger rods. Includes clamps.
- 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.
- 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.
