XCMG cranes — from the 16-tonne QY16C truck crane to the 130-tonne QAY130 all-terrain and the 150-tonne QUY150 crawler — are the backbone of construction, infrastructure, and industrial lifting projects across Africa, the Middle East, Southeast Asia, and South America. Their competitive pricing, proven reliability, and extensive dealer network have made XCMG the world's largest crane manufacturer by volume. But like all heavy lifting equipment, XCMG cranes require precision-matched spare parts to maintain load chart compliance and safe operation.
This guide covers the complete XCMG crane spare parts landscape across four crane families (QY truck cranes, QUY crawler cranes, QAY all-terrain cranes, and XCT U-series). You will find a model-by-model specification table, six component system breakdowns with common failure patterns, a three-tier quality comparison, an inspection and maintenance schedule, and a practical ordering process that uses crane serial number + load chart cross-referencing to eliminate wrong-part shipments.
Whether you operate a single QY25K5 in Saudi Arabia or a fleet of QUY150 crawler cranes in Indonesia, this guide is built to help you source parts faster, compare quality tiers intelligently, and keep your cranes lifting safely.
Chapter 1: XCMG Crane Model Overview
XCMG produces cranes across four primary families, each designed for different lifting applications and site conditions. Understanding which family your crane belongs to is the first step in sourcing correct spare parts — because even within the same model series, engine configurations, hydraulic pump brands, and slewing bearing sizes can vary by production year.
QY Series — Truck Cranes (16t to 100t)
The QY series is XCMG's highest-volume export line. These truck-mounted cranes are the most common XCMG cranes on international construction sites. The QY25K5 and QY50K are the top-selling models globally.
| Model | Max Lift | Boom Length | Engine | Chassis |
|---|---|---|---|---|
| QY16C | 16 t | 31.5 m (4-section) | Weichai WP6 / Yuchai | XCMG custom |
| QY25K / K5 | 25 t | 33.5–41 m (4-5 section) | Weichai WP7 / SC11CB | XCMG custom |
| QY35K | 35 t | 42 m (5-section) | Weichai WP10 / SC12 | XCMG custom |
| QY50K | 50 t | 45 m (5-section) | Weichai WP12 / OM457 | XCMG custom |
| QY70K | 70 t | 51 m (6-section) | Weichai WP12 | XCMG custom |
| QY100K | 100 t | 58 m (6-section) | Weichai WP12 / Mercedes OM501 | XCMG custom |
QUY Series — Crawler Cranes (75t to 150t)
The QUY series crawler cranes are used for heavy lifting in fixed positions — wind turbine installation, steel structure erection, and bridge construction. Their tracked undercarriage provides stability without outriggers.
| Model | Max Lift | Boom Length | Engine | Track Width |
|---|---|---|---|---|
| QUY75 | 75 t | 52 m main + 17 m jib | Weichai WP6 | 800 mm |
| QUY80 / 80U | 80 t | 55 m main + 19 m jib | Weichai WP6 / WP10 | 800 mm |
| QUY150 | 150 t | 70 m main + 30 m jib | Weichai WP10 | 900 mm |
QAY & XCT Series — All-Terrain Cranes
The QAY series all-terrain cranes combine on-road mobility with off-road capability. The XCT U-series represents XCMG's newer generation with upgraded hydraulic systems and electronic controls.
| Model | Max Lift | Boom Length | Drive Type | Key Feature |
|---|---|---|---|---|
| QAY25 | 25 t | 36 m (4-section) | 6x4x6 | All-terrain, 80 km/h road speed |
| QAY130 | 130 t | 60 m (7-section) | 10x8x8 | Heavy all-terrain, 5-axle |
| XCT90U | 90 t | 52 m (6-section) | 8x4x8 | New-gen U-series, upgraded ECU |
Chapter 2: Six Component Systems
XCMG cranes consist of six primary component systems. Each system has distinct failure patterns and spare part requirements. Understanding these systems helps you identify the right parts faster and avoid ordering errors.
💧 1. Hydraulic System
The hydraulic system powers all crane movements: boom extension/retraction, winch hoisting/lowering, slewing, and outrigger deployment. It is the most frequently serviced system on any crane.
Common failures: Cylinder seal leaks (most frequent), pump cavitation from contaminated oil, counterbalance valve drift causing load creep, hose burst from age/pressure spikes.
🔧 2. Engine & Powertrain
The engine provides power for both the crane carrier (driving) and the upper structure (lifting). Truck cranes use a single engine; some all-terrain models use a second engine for the superstructure.
Common failures: Injector wear from poor fuel quality (Africa/Middle East), turbocharger bearing failure, water pump leakage, fuel filter clogging, clutch wear in manual transmissions.
🔁 3. Slewing & Lifting System
The slewing system rotates the upper structure, while the lifting system handles load hoisting and lowering. These are the most safety-critical systems on the crane.
Common failures: Slewing bearing race wear (causes grinding noise and play), wire rope fray/broken strands, winch reducer gear tooth pitting, hook block pin wear.
🧰 4. Electrical & Control System
Modern XCMG cranes (especially XCT U-series and post-2018 QY models) use sophisticated electronic control systems for load monitoring, engine management, and hydraulic proportional control.
Common failures: LMI sensor drift (requires recalibration), solenoid coil burnout, wiring harness chafing near boom pivot, display panel failure from vibration, CAN bus communication errors.
🏗 5. Structural & Chassis Parts
Structural components carry the crane's weight and lifting loads. While they rarely fail suddenly, they require regular inspection for cracks, deformation, and connection wear.
Common failures: Outrigger pad wear from hard surfaces, pin/bushing wear at boom pivot points, structural crack initiation at weld toes (requires NDT inspection), counterweight mounting bolt loosening.
🛠 6. Wear & Maintenance Parts
These are the consumable parts that require scheduled replacement. Having a stock of these on-site minimizes downtime for routine maintenance.
Recommended stock: Keep one full filter set (air + fuel + oil) per crane per quarter. Seal kits for boom telescope cylinders should be stocked in advance — they take 15-30 days to source.
Chapter 3: Three Quality Tiers Explained
Not every part on a crane needs to be genuine OEM. Understanding when to use genuine, OEM-grade, or aftermarket parts can save 30-50% on maintenance costs without compromising safety.
XCMG Genuine Parts — Manufactured by or for XCMG with full factory warranty (12 months). Stamped with XCMG part numbers. Use for: safety-critical components (hooks, wire ropes, LMI sensors), slewing bearings, and main hydraulic pumps. These parts come in XCMG packaging with factory traceability codes.
Price index: 100% (baseline) | Warranty: 12 months / 2,000 hours
OEM-Grade Parts — Manufactured by the same suppliers who make parts for XCMG (e.g., Rexroth hydraulic pumps, SKF bearings, Bosch injectors) but sold without XCMG branding. Identical specifications, identical quality, lower price. Use for: hydraulic cylinders, filters, bearings, seals, and most engine components.
Price index: 60-75% of genuine | Warranty: 6 months / 1,000 hours
Aftermarket Parts — Manufactured by third-party factories to compatible specifications. Quality varies significantly by supplier. Use for: non-safety-critical parts (lighting, cab trim, standard fasteners), and when budget constraints are severe. Never use for load-bearing or hydraulic safety components.
Price index: 30-50% of genuine | Warranty: 3 months
Chapter 4: Inspection & Maintenance Schedule
Regular inspection and preventive maintenance are the most effective ways to reduce unplanned crane downtime. The following schedule is based on XCMG factory recommendations and field experience from operators in Africa and the Middle East.
| Interval | Components | Actions |
|---|---|---|
| Daily (pre-shift) | Wire ropes, hooks, hydraulic oil level, tire pressure, lights, horn | Visual inspection, function test, oil level check |
| Weekly (50 hrs) | Boom sections, outriggers, slewing bearing, LMI display | Grease boom slide pads, inspect rope condition, test LMI alarm |
| Monthly (200 hrs) | Hydraulic filters, fuel filter, air filter, battery, brake system | Check filter condition, clean air filter, test brake response |
| Quarterly (500 hrs) | Hydraulic oil, winch reducers, slewing gear, pin/bushing clearances | Sample hydraulic oil, change winch oil, measure pin wear |
| Semi-annual (1,000 hrs) | Engine tune-up, clutch, transmission, axles, electrical connections | Adjust valve clearance, check clutch free play, inspect wiring |
| Annual (2,000 hrs) | Full hydraulic oil change, slewing bearing inspection, structural NDT | Replace all hydraulic oil, mag-particle inspect boom welds, recertify LMI |
Chapter 5: Common Breakdown Scenarios & Required Parts
Understanding common failure scenarios helps you prepare the right spare parts before they're urgently needed. Here are the six most frequent XCMG crane breakdown scenarios reported by operators:
Scenario 1: Boom Drift Under Load
Symptom: The boom slowly retracts or extends while holding a load, even with the control lever in neutral.
Cause: Counterbalance valve internal leakage or telescope cylinder seal failure.
Required parts: Counterbalance valve repair kit (or replacement valve), telescope cylinder seal kit, hydraulic oil (for refill after repair).
Scenario 2: Winch Won't Hold Load
Symptom: The load slowly drops when the winch control is released.
Cause: Winch motor brake wear, or counterbalance valve failure.
Required parts: Winch brake friction plates, brake release valve, winch motor seal kit. If the brake housing is scored, a complete winch motor overhaul kit is needed.
Scenario 3: Slewing Grinding Noise
Symptom: Grinding or clicking noise during slewing rotation, especially under load.
Cause: Slewing bearing race wear, or slewing gear tooth damage.
Required parts: Slewing bearing (full replacement, 15-30 day lead time), slewing gear inspection cover gasket, grease (high-grade lithium complex). This is a major repair requiring 2-3 days of crane downtime.
Scenario 4: Hydraulic Overheating
Symptom: Hydraulic oil temperature exceeds 80°C, crane enters protection mode and stops lifting.
Cause: Hydraulic oil cooler blockage, low oil level, or internal pump leakage generating excess heat.
Required parts: Hydraulic oil cooler core, hydraulic oil (ISO VG46), main pump seal kit (if pump leakage is the cause). Clean the cooler fins with compressed air as a first step.
Scenario 5: LMI System Alarm
Symptom: Load moment indicator shows continuous alarm or incorrect readings, preventing lifting operations.
Cause: LMI sensor drift, damaged angle/length sensor, or wiring harness fault.
Required parts: LMI angle sensor, LMI length sensor (cable reel type), wiring harness section. After replacement, the LMI must be recalibrated using test weights.
Scenario 6: Engine Power Loss
Symptom: Engine lacks power during driving or lifting, black smoke from exhaust.
Cause: Clogged fuel filter, injector wear, turbocharger failure, or air filter blockage.
Required parts: Fuel filter element, air filter element, fuel injector set (if wear confirmed), turbocharger cartridge rebuild kit. In dusty environments, air filter life can be as short as 200 hours.
Chapter 6: How to Order XCMG Crane Parts — Step by Step
Ordering the correct XCMG crane spare part requires more than just the model number. Follow this process to ensure you receive the right part on the first attempt:
- Identify your crane model and serial number. The serial number is stamped on the crane data plate (usually on the turntable or chassis frame). The serial number tells us the production year, engine configuration, and exact component variants.
- Identify the engine model. Check the engine nameplate on the cylinder block. XCMG uses Weichai, Yuchai, Mercedes, and SC engines across the same model line. Engine parts cannot be ordered by crane model alone.
- Provide the part name or function. If you don't have the XCMG part number, describe the part: "boom telescope cylinder seal kit for QY50K, 2018 production." Photos of the failed part and its location on the crane are extremely helpful.
- Specify your quality tier preference. Genuine, OEM-grade, or aftermarket. For safety-critical parts, we will recommend genuine even if you request aftermarket.
- Send to Archer Parts. Email linwl@archermach.com or WhatsApp +86 178 6053 9508. We return a matched quotation with all available quality tier options within 24 hours.
- Pre-shipment photo verification. Before shipping, we send photos of the exact parts with part numbers visible. You verify — then we ship.

The crane serial number is stamped on the data plate attached to the turntable (upper structure) near the operator's cab. On older models, it may also be stamped directly on the chassis frame rail near the front axle. The serial number format is typically 10-14 characters and includes the model code and production sequence. If the data plate is missing or unreadable, the engine serial number and hydraulic pump model can help us identify the correct parts.
We do not recommend aftermarket main hydraulic pumps for any crane. The main pump (typically a Rexroth A4VG or Kawasaki K3V series) operates at pressures up to 350 bar and directly affects load-holding safety. Aftermarket pumps often have wider tolerance bands, leading to inconsistent flow rates and potential load drift. We supply OEM-grade Rexroth/Kawasaki pumps (same factory, no XCMG branding) at 60-75% of the genuine price — this is the best balance of cost and safety. For pilot pumps and gear pumps, OEM-grade is also recommended; aftermarket is acceptable only for return-line low-pressure pumps.
Wire rope replacement depends on usage intensity and inspection findings. The general guidelines are: visual inspection every shift (daily), detailed inspection monthly (check for broken wires, diameter reduction, corrosion, deformation), and replacement when: (a) 6+ broken wires in one rope lay, (b) diameter reduction exceeding 7% of nominal, (c) visible rust pitting, or (d) any kink or birdcage deformation. In typical construction use (200-400 hours/month), wire ropes last 12-18 months. In heavy-duty applications (steel mills, ports), replacement every 6-9 months is common. Always use wire ropes that meet the crane's original breaking strength specification.
Slewing bearings are long-lead-time items because they are model-specific and manufactured to precise dimensions. Genuine XCMG slewing bearings: 25-45 days from order confirmation (XCMG produces in batch cycles). OEM-grade slewing bearings from the same manufacturer (usually Xuzhou Bearing Factory or Rothe Erde): 15-25 days. We maintain a cross-reference database of slewing bearing dimensions (outer race diameter, inner race diameter, gear teeth count, ball/roller size) so we can match the correct bearing even without the XCMG part number. Tip: If your slewing bearing is showing signs of wear (play, grinding noise), order the replacement immediately — do not wait until failure, as emergency air freight for a 200-500 kg bearing is extremely expensive.
Yes. We support legacy XCMG crane models including the older QY8, QY12, QY16 (non-C variant), QY20, and early QY25 (pre-K series). Part availability depends on the specific component: Filters, seals, bearings, and brake components are generally still available. Engine parts for older Weichai/Yuchai engines are available as OEM-grade. Electrical components (ECUs, displays) for pre-2010 models may require sourcing from remaining factory stock or compatible substitutes. Send us the crane serial number and a photo of the data plate — we will confirm part availability within 24 hours.
Express air freight (DHL/FedEx/UPS): 5-7 days for parts under 30 kg — ideal for urgent breakdown parts (seal kits, sensors, valves). Standard air freight: 7-12 days for 30-100 kg shipments. Sea freight: 25-40 days to most ports — recommended for heavy parts (slewing bearings, winch assemblies, structural components) and bulk orders over 100 kg. We handle all export documentation, including commercial invoice, packing list, bill of lading, and certificate of origin. For crane parts destined for construction sites, we can arrange door-to-door delivery via our freight forwarder network in Africa, Middle East, and Southeast Asia.
