Powered or motorized trolleys are the most common suspension method for hoists over 2 ton capacities. They are also a time saving investment when used on lengthy runways. Motorized trolleys either attach directly to a lug suspended hoist, forming an integrated material handling unit, or are manufactured with a clevis for top hook hoist hookup. Through the use of a pendant throttle, the operator is able to control the hoist/trolley functions, thus increasing load handling efficiency and speed. Motor driven trolleys are designed in both electric and air driven models. Below are some of the units that J. Herbert Corporation distributes. Please consult our Customer Service Department to identify the trolley best suited for your application.
