Chester Tractor Drives deliver greater productivity with existing push-type underhung crane bridges or push-type monorail hoists by offering motorized travel.

Units are adjustable for standard I-beams and flat-flange beams from 3.38" to 8" wide. Steel plate construction with tie rods for easy adjustment. Direct drive with right-angle worm gear reducer.

Additional features and benefits include:

• Designed for capacities up to 5 tons, Chester Tractor Drives are easy to install without removing or disturbing existing equipment.
• For underhung crane bridges the Tractor is designed to accommodate any make of crane on various tracks. Twin Tractor units can be used to convert push-type cranes to motorized drive. The twin Tractor drives are wired into a single control panel located on one of the Tractors to provide simultaneous operation.
• For monorail trolley suspended hoists, the single, powerful motorized Tractor provides fast horizontal travel while minimizing worker fatigue. A squirrel cage electric motor and heavy-duty worm gear reducer drives a urethane drive wheel. The drive wheel engages the underside of the track, providing positive travel.
• Units are available for a variety of capacities, speeds and runway beams. Units are available with standard controls for single or dual operation, without controls or with customized controls.
• Other options include, two speed, variable speed, soft starts, motor brakes, various voltages and control options.
