- With fully security protection system, main and auxiliary winches are equipped with over roll out limiter and height limiters to prevent over-rolling out and over-hoisting of steel rope, including tip-over and limit angle protection.
- Load moment limiter: The adoption of high intelligent load moment limiter system can comprehensively protect lifting operation, ensuring accurate, stable and comfort operation.
- The fault diagnosis system can detect superstructure electricity, hydraulic action, chassis (for major safety failure), engine and gearbox for fault to ensure reliable operation of the crane.
Luffing system:
- Dead-weight luffing provides more stable luffing operation at low energy loss.
- Luffing angle: -2°~ 80°.
Telescopic system
Four-section boom is applied with basic boom length of 11.25m, full-extended boom length of 34.5m and lifting height of fully extended boom length of 35 m. It is made of fine grain high-strength steel with U-shaped cross-section and with telescopic operation controlled independent by dual- cylinder rope.
Slewing system:
360° rotation can be achieved with Max. slewing speed of 2.0r/min. Hydraulic controlled proportional speed adjustment is applied to provide stable and reliable operation of the system. Unique rotary buffer design ensures more stable braking.
Hoisting system
- The adoption of pump and motor double variable speed control ensures high effi ciency and excellent energy saving functionality. With perfect combination of winch balance valve and unique anti-slip technology, heavy load can lift and lower smoothly. Closed winch brake and winch balance valve effectively prevent imbalance of the hook.
- One main hook: 550Kg, and the Max. lifting capacity is 45t. Wire rope of main winch: lefthanded wire rope 18-35W×7-1960USZ 220m.
Safety system
- Load moment limiter: Load moment limiter calculation system based on lifting load mechanical model is established using an analytical mechanics method with rated lifting accuracy up to ±3% through on-line non-load calibration, providing full protection to lifting operation. In case of overload operation, system will automatically issue an alarm to provide safety protection for manipulation.
- Hydraulic system is configured with the balance valve, overflow valve and two-way hydraulic lock etc. components, thus achieving stable and reliable operation of the hydraulic system.
- Winches are equipped with over roll-out limiter to prevent over rolling-out of wire rope.
- Boom ends are equipped with height limiters to prevent over-hoisting of wire rope.
- Length and Angle sensor and pressure sensor are equipped to indicate the working condition of whole crane in real-time, giving an alarm and cutting off the dangerous action automatically.

- Brakes system includes traveling brake, parking brake, emergency brake and auxiliary brake.
- Traveling brake: All wheels use the air servo brakes and dual-circuit brake system.
- Parking brake: Force driven by accumulator is applied on the third to fourth axle.
- For emergency brake, accumulator is used not only for cutting-off brake but also for emergency brake.
- Auxiliary brake is exhaust brake with brake safety ensured while travelling downhill.
Suspension system:
The 1st and 2nd front axles adopt plate spring suspension systems and the 3rd and 4th rear axles adopt rubber suspension system. With 100,000 fatigue tests and optimization of performance parameters of the front and rear suspension, the strength and comfort are ensured.
Steering system:
Hydraulic power mechanical steering systems are applied for axles 1 and 2 with unloading valve installed in the steering gear.
Outriggers:
Four-point supporting of the H-shaped outriggers ensures easy operation and
strong stability with max. span up to 6m×7.2m. They are made of fi ne-grain
high-strength steel sheet with horizontal single-cylinder rope line
telescoping for fi rst and second outriggers. Vertical cylinder of outrigger
