CM isn’t only an innovator of chain hoist technology. The CM Series 632 Close Radius Trolley is an advancement in trolley design that hangs high above the competition. The Series 632 Trolley is shorter, more compact, and 50% lighter than competitive trolleys without losing any of the strength.
Durable materials make the Series 632 Trolley tough, and a streamlined product design allows this trolley to negotiate some of the tightest curves you can throw at it. Low headroom applications will benefit from the Series 632 Trolley, and lifetime lubricated bearings and greater wear capacity result in less maintenance. With a lifetime warranty, this trolley made in the USA is a prominent product in CM’s trolley range.
