Zoomlion Crane Winch Motor

Winch motor and hydraulic drive parts for Zoomlion truck crane maintenance. Winch capacity scales with the crane: the ZTC250V is a 25 t machine and the ZTC550V a 55 t machine at more than twice the base boom moment, so the main hoist motor, its brake and the reduction gearbox are a size class apart between them. The main hoist and the auxiliary hoist on the same crane are also different assemblies, which is worth stating on the enquiry rather than leaving us to ask. Crane part numbers are split between the chassis book and the superstructure book, so anything on the winch is quoted against the superstructure serial number. If the complaint is a hoist that creeps under load, look at the brake and the counterbalance valve before the motor — those are much cheaper parts and they account for most creep faults.
