Single Girder, Under Running, Dual-Motor Overhead Cranes

Uesco Cranes manufactures single girder cranes for a vast array of applications and environments. Our single girder, under running, dual-motor overhead cranes feature capacities from 2 tons to 10 tons. These cranes require electrification and can be used for applications where trolley approach is crucial. Each of these cranes has forged steel wheels with a crowned or flat tread for operation on standard S beam, wide flange beam, or patented track. End trucks are fabricated from structural steel channels welded to a rigid frame. You may use a variety of hoist types, but frequently electric wire rope hoists are preferred options, but electric and air chain hoists can be used.

All Uesco dual-motor crane drives are double or triple reduction parallel shaft, helical/spur reducers splash lubricated for dependable service and longer life. Minimum B-10 bearing life is 5,000 hours. The bridge drive motors are flange mounted with a standard NEMA C or D flange and are 30 minute rated with Class F insulation. Thermal detectors embedded in the motor windings provide overload protection and meet the latest publication of the National Electric Code.

Built of structural steel girders, which meet or exceed CMAA design specifications plus OSHA and ANSI standards, all of our overhead crane solutions have a minimum deflection of 1/600 with a built-in safety factor of 5 to 1. All Uesco overhead cranes are rated for a minimum CMAA Class C service. Standard speeds are 50, 80, or 120 FPM. Spans are from 10′ to 65′ in length. We also custom fabricate runways in different configurations depending on your company’s requirements. Rubber bumpers and rail sweeps are standard on all cranes.
