Geared Monorail Travelling Trolley
Hand geared trolleys are an excellent option when accurate load spotting is a must. Geared trolleys are also referred to as hand geared trolleys and incorporate a looped hand chain, which is attached to a hand chain wheel or sprocket. When the operator pulls the hand chain, the sprocket then engages the gears which facilitate wheel movement. Upon pulling the chain,
models are available in metric rated capacities from 1 through 5 tons. They incorporate dual tread wheels with lifetime lubricated bearings, steel wrap around side plates, and a universal hanging clevis that works with most hook mounted hoists.
Hand chains have a standard 10' drop. Other lengths available.
