About trolley winch:
Double girder overhead winch trolley is widely used especially when the electric hoist as a light duty lifting mechanism can't meet the lifting demands, It is composed of electric hoist/electric winch, wheel and trolley frame, through the rails installed on the crane beams, the trolley can realize traveling from one side to another.
Compared to wire rope hoists, winches only need a few rope reeving even for high loads, making a very compact construction possible. Load capacities: 5–450 tons.
Winch Trolleys & Hoist Trolleys:
The unit incorporating the lifting mechanism comes in two versions, generally chosen on the basis of the intended use of the machine: the hoist trolley and the winch trolley.
The hoist trolley comprises a frame built by us to allow travel and to accommodate the hoist, a lifting unit whose components are arranged in a single assembly all on the same axis.
The winch trolley differs from the hoist trolley in that the lifting mechanism components are separate and not arranged along the same axis. These units are generally used in more heavy-duty machines, since they are custom sized to meet individual requirements.
