Harrington UM 3 Ton Underhung Motorized End Trucks 35 ft. Span
$5,169.17
For heavy-duty class "C" single girder crane applications, Harrington underhung motorized end trucks combine superior performance with underhung space savings. Along with a full range of features, end truck kits include two trucks; two sealed, totally enclosed, non-ventilated (TENV) motors with adjustable D.C. brakes; two helical gear reducers; rubber bumpers; and bridge beam fastener set. All trucks are fully painted. Bridge fabrication prints are also included. As a member of the Crane Manufacturers Association of America (CMAA), Harrington builds UM trucks to meet current industry and regulatory codes.
