XCMG Crane Slewing Bearing
Slewing bearing and related crane rotation parts for XCMG lifting fleets and oilfield construction sites. A slewing bearing is a structural safety part: XCMG crane model codes carry suffixes (XCT25L5_S and XCT25L5_SR are not the same build) and tooth count, raceway diameter and bolt hole pattern can differ between them. We quote these only against the full nameplate code and the machine serial number — never against a shortened model name.

SANY Hydraulic Cylinder Seal Kit
Seal kit matching for SANY boom, arm, bucket and outrigger cylinders. Seal kits are identified by the cylinder, not by the machine: bore diameter, rod diameter and the seal groove arrangement decide the kit, and a single excavator carries boom, arm and bucket cylinders in three different sizes, while a truck crane adds outrigger and telescoping cylinders again different. This listing spans a 21.9 t excavator, a 35 to 38.1 t excavator and a 25 t class truck crane, which have nothing in common at cylinder level. Measure the rod diameter and the bore and send those with the machine serial number. Two things worth knowing: a cylinder that has been resealed twice and still leaks usually has a scored rod or a worn gland bore, and no seal kit will fix that; and it is better to buy the kit for the cylinder you are opening than a set for the machine, because a cylinder that is not leaking is best left closed.

SANY Crane Outrigger Cylinder Parts
Cylinder components and seals for SANY truck crane outrigger systems. Outriggers are a structural safety system and the parts scale with the crane: the STC250 sits at 32.1 to 33.1 t operating weight on a 6.4 by 5.35 m outrigger span with 7 t of counterweight, while the STC500 hybrid builds carry 8.5 to 11 t of counterweight on spans up to 8.0 by 6.42 m. Nothing interchanges across the range, and the suffix matters even within one model — the STC250C5-1 and the STC250C5-8 already differ from each other in outrigger span. Outrigger cylinders carry load-holding valves and those must be replaced like for like: substituting a valve with a different cracking pressure on a load-bearing circuit is not a saving worth making. Send both the chassis nameplate and the superstructure serial number, since crane parts are documented in two separate books.
Electrical parts
Zoomlion Crane Load Moment Sensor
Load moment sensor and safety system component matching for Zoomlion cranes. The load moment limiter is the primary safety system on the crane and its parts are not generic: the ZTC250V is a 25 t machine with a 960 kN.m base boom moment while the ZTC550V is a 55 t machine at 2,033 kN.m, so the length sensor, angle sensor, pressure transducers and limiter display are all matched to the specific machine and to the boom configuration it was built with. We quote these only against the full model code and the superstructure serial number. One thing to establish before buying: a limiter that reads wrong is more often a calibration or a wiring fault than a failed sensor, and a new sensor fitted to a system nobody recalibrates will read wrong in exactly the same way. Tell us what the system is doing and we will help narrow it down first.

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.
Hydraulic parts
Zoomlion Crane Hydraulic Hose Kit
Hydraulic hose kits quoted by crane model, hose length, fitting type and pressure requirement. Hoses are the item on a crane where the machine model tells us the least. What identifies a hose is the inside diameter, the length between fitting faces, the fitting type and thread at each end, the orientation of any bend, and the pressure rating of the circuit it serves. Photograph the failed hose with the layline text if it is still readable and measure it end to end. Two things worth knowing before ordering: boom hoses run inside the sections and are routed to a specific length, so a hose that is merely close will chafe through and fail again; and once one hose in a circuit has failed from age, the rest of that circuit is the same age, which is why we quote them as a set rather than one at a time.
