Trolleys, connected to a hoist, enable the cross-direction movement of a load. The machine drive-through operation can either manual or motorised. Trolleys are generally either push or pull types or comprise a geared wheel with electric motor.

The Trolley wheels are ideal for the I as well as the H constructions of the monorail beams and the single girder beam of the cranes. The right-angled side plates add to protection from wheel shaft breakage, from falling down and work as a beam flange cleaner.

An adjustable double axle equalises the trolley wheel load on improper beam flanges. A trolley also comes with powder plated side plates, alloy steel wheels with double ball bearings lubricated for life and, white zinc coated hand chains and hand chain wheels. The light weight electric drive comes with a powerful AC brake motor.
