Double Girder Underhung Motorized End Trucks

Finding Real World Solutions

Harrington MUM end trucks offer the same benefits of the UM underhung motorized single girder series, but in a compact, double girder configuration. Unique for double girder cranes, these end trucks offer the dimensional advantage of an underhung crane combined with a top running trolley.

Heavy-Duty Drives

Drives are designed for crane service, with a 30 minute rating and feature cooling fins for efficient heat dissipation.

UNDERHUNG SPACE SAVING DESIGN

Get the most out of your space by using our underhung end trucks to move heavy-duty, class "C" cranes.

Side Guide Rollers and Rubber Bumpers

Unique side guide rollers reduce wheel friction and allow smooth crane travel and rubber bumpers are included.
