Alu-Track™ Bridge Cranes & Runways
Applications: workstation bridge cranes and runways and monorail cranes
Material: extruded high-strength 6061-T6 aluminum alloy
Capacities: from 250 to 3000 lbs
Span Lengths: up to 29 feet, dependent on desired capacity
Spanco Alu-Track™ Bridge Cranes and Runways are made with our aluminum enclosed track for performance that’s lightweight, durable, maintenance-free, and non-corroding.
Alu-Track aluminum enclosed tracks reduce the overall system weight, so you can more easily move the bridge crane. Plus, for ceiling-mounted workstation bridge cranes, Alu-Track systems mean less weight on your roof support structure.
- Clean rooms
- Refrigerated areas, including food packaging applications
- Moisture-laden environments
- Acidic environments (but not for base/alkaline)
- R&D labs
- Wherever lightweight, durable enclosed track is required
- The entire length of the top side of the track accepts hangers. Once hung, the aluminum tracks are easily and precisely aligned.
- The internally tapered track self-centers trolleys and end trucks, so rolling movement is smooth, quiet, and highly ergonomic.
We made three models of Alu-Track enclosed track; for track profiles, see Photo Gallery.
- 306 Alu-Track: six inches overall height, with same internal dimensions as the Spanco 600 Series enclosed steel track.
- 308 Alu-Track: eight inches overall height, with same internal dimensions as the Spanco 700 Series enclosed steel track.
- Reinforced 308 Alu-Track: twelve and a half inches overall height, with same internal dimensions as the Spanco 700 Series enclosed steel track, plus an extruded, reinforcing strong-back for heavier loads over longer spans.
Options for Spanco Alu-Track™ Bridge Cranes & Runways
- 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.
- 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.
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 our 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.

Spanco, Inc. warrants its manual workstation bridge crane products, jib crane products, and gantry crane products to be free from defects in material and workmanship for a period of ten (10) years or 20,000 hours, commencing on the date of shipment to the first retail purchaser. This warranty extends to non-wearable parts only, with the exception of the wheels supplied on manually operated workstation end trucks and hoist trolleys. This warranty does not cover defective equipment or system failure caused by misuse, negligence, improper installation or maintenance, or equipment that has been used in excess of its rated capacity or beyond its service factors. It does not apply to equipment that has been altered without Spanco’s written authorization.
Written notice of any claimed system defect must be given to Spanco within thirty days of discovery. Spanco's obligation under this warranty is limited to the replacement or repair of Spanco’s products at the factory or separate location approved by Spanco.

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 48” from the runway support centers when aligning Alu-Track runways.
- Do not cantilever the runway track ends more than 18” beyond the runway support centers (not including festoon storage area) on Alu-Track runways.
- 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.
