Single Girder Top Running Motorized End Trucks

Quality to Count On

For heavy-duty class “C” single girder crane applications, nothing tops Harrington top running motorized end trucks. Superior strength, rigidity and compactness comes from frame fabrication of ASTM A500 structural tube. 

Heavy-Duty Drives

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

Rubber Bumpers

Standard rubber bumpers are included for protection from collision.

Minimize Assembly Labor

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

Heavy Duty Side Guide Rollers

Reduced wheel friction due to heavy-duty side guide rollers results in smooth crane travel. Guide rollers are 3 1/2" O.D. with fixed steel axels.
