Product Description
The QY25K5D-5 is a 25-ton medium-duty hydraulic truck crane designed for high-frequency, narrow-space, and multi-scenario lifting operations. It features a 41m five-section synchronous telescopic main boom (2nd/3rd/4th/5th sections extend simultaneously), eliminating repeated mode switching and reducing misoperation risks. With a compact body (13,050×2,550×3,500mm) and a 32.5t operating weight, it adapts to 98% of urban/rural roads, bridges, and tunnels. Powered by a fuel-efficient diesel engine (220kW/2200rpm) and equipped with an intelligent hydraulic control system, it delivers strong lifting performance, smooth compound actions, and high reliability. The reinforced boom structure (10% larger cross-section) and heavy-duty slewing ring ensure stable lifting in harsh conditions. Ideal for municipal works, building construction, bridge projects, and logistics handling, it balances efficiency, safety, and low operation costs.
Product Advantages
High Efficiency & Synchronous Telescopic Boom: 41m main boom with 2–5th section synchronous extension (no sequence required), 80% faster extension than dual-cylinder models; main boom full extension ≤93s.
Strong Lifting Capacity & Stability: 10% larger boom cross-section, high-strength steel boom, and 6-ton counterweight; max lifting moment 1,005kN·m; 5.14×6.0m outrigger span for ultra stability.
Compact & Flexible for Narrow Spaces: 13.05m×2.55m×3.5m body, 22m minimum turning diameter, 40% gradeability; adapts to urban streets, rural roads, and tight job sites.
Energy-Saving & Low Operation Cost: Euro VI-compliant diesel engine with optimized fuel injection; intelligent hydraulic system reduces fuel consumption by 8–10% vs. peers; no urea required.
Safe & Comfortable Operation: FOPS/ROPS-certified cab with 10-inch touchscreen, 360° camera, and automatic AC; smooth lifting/luffing/slewing with low shock; multiple safety interlocks.
Easy Maintenance & Durable: Ground-level access to filters and hydraulic components; reinforced chassis and wear-resistant parts; 1-year/2,000-hour standard warranty.

Operation Guidelines
1 .Pre-Operation Inspection
Check engine oil, coolant, hydraulic oil, and fuel levels; inspect hoses/joints for leaks.
Verify outriggers, boom sections, and pins for wear, looseness, or damage; tighten loose parts.
Test safety devices: seat belt, emergency stop, 360° camera, horn, and touchscreen (no fault alarms).
Check tire pressure and wear; ensure outrigger pads are intact and placed on firm ground.
2 .Starting & Operation
Enter the cab, fasten the seat belt, adjust the seat, and set all levers to neutral.
Turn the key to “ON”, wait 15s for system self-check, then start the engine; idle 3–5min to warm up.
Extend outriggers fully, level the crane via the touchscreen, and set the lifting mode (standard/heavy).
Operate levers: left for slewing/boom luffing, right for boom extension/hook hoisting; avoid sudden movements.
After operation: lower the hook, retract the boom, stow outriggers, idle 2–3min, then turn off the engine.
3 .Safety Notes
Never exceed the rated lifting capacity; avoid lifting on slopes >3°.
Keep a 5m safe distance from personnel/obstacles; no standing under the boom/hook.
Do not operate in severe weather (heavy rain, wind>6 级，fog) or near power lines.
Use outrigger pads on soft ground; never move the crane with a suspended load.
FAQ
Q1: What is the fuel consumption under standard conditions?
A1: 18–22 L/h (standard lifting mode); eco mode reduces consumption by 5–8%.
Q2: Does it support synchronous extension of all boom sections?
A2: Yes. 2nd–5th sections extend synchronously with no sequence required, improving efficiency.
Q3: What is the warranty period?
A3: Standard warranty: 1 year or 2,000 working hours (whichever comes first); extended warranty available.
Q4: What is the maximum lifting height with a jib?
A4: Up to 49.3 m (41m main boom + 8.3m jib).
Q5: How to handle a boom extension fault?
A5: Check hydraulic oil level and filters first; restart the system if the alarm persists. Contact professional maintenance if the fault remains.
