Identifying your Zoomlion crane
Zoomlion truck cranes commonly appear as ZTC series (e.g. ZTC250V, ZTC550V) and earlier QY series machines. The model code reflects the lifting class, while the suffix letters mark the series version. As with all Chinese equipment, the chassis nameplate and the superstructure serial number together define which parts fit — cranes combine a truck chassis and a lifting superstructure that are documented separately in the parts books.
Safety system and LMI parts
The load moment indicator (LMI), length and angle sensors, anti-two-block switches and pressure transducers are the parts that most often take a crane out of service, because the crane will not lift safely — or at all — without them. These electronic parts are version-sensitive: always quote them with the LMI system model from the cab display and photos of the old sensor labels.
Hydraulic and structural wear parts
Beyond electronics, the recurring demand is for outrigger and telescoping cylinder seal kits, winch motors and reducers, slewing bearings, balance valves, boom wear pads and hydraulic hose kits. Hose kits should be quoted by length, fitting type and pressure rating rather than by machine model alone, since field-repaired cranes often carry non-original hose routings.
What to send for a fast quote
For Zoomlion cranes the complete quote package is: chassis nameplate photo, superstructure serial number, OEM part numbers or parts book positions, photos of old parts for anything electronic, quantity and destination port. With this set, compatibility for most items can be confirmed within one working day.
Frequently Asked Questions
Do you need to be an authorized Zoomlion dealer to supply these parts?
Aftermarket suppliers legitimately source OEM and OEM-equivalent parts through factory-adjacent supply chains. Brand names and part numbers are used for identification only; if authorized-channel documentation matters for your procurement rules, confirm the supply route before ordering.
Are QY series parts still available for older cranes?
Most wear parts for older QY series cranes remain available through OEM and equivalent channels, though some electronic parts may be superseded by updated versions that require confirmation against the crane serial number.
