Double Girder Top Running Motorized End Trucks

You Dream it, We Build it!

For a compact, double girder configuration with all the benefits of the TM top running motorized single girder design, go with Harrington MTM end trucks. 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.

Heavy-Duty Drives

Heavy-duty drives are designed for crane service with 30 minute rating and feature cooling fins for efficient heat dissipation.


Fully machined frames—girder connection, bracing and collector mounting bracket holes are drilled and tapped for easy installation.

Rubber Bumpers

Standard rubber bumpers are included for protection from collision.
