Double-axle drive is used, providing good trafficability and comfortableness under complex road condition with reliable traveling performance. Engine has the multimode power output function, which reduces power consumption. The use of tipping over early-warning technology provides high stability and safety of the overall operation.

Ultra long, super strong and highly sensitive load lifting capacity

Four-section boom of high strength steel structure and optimized U-shaped cross section reduces weight significantly with higher safety rates.

Highly efficient, stable, energy-saving, and adjustable hydraulic system

Hydraulic system load feedback and constant power control is applied to provide strong lifting capacity and good micromobility. Unique steering buffer design is adopted to ensure stable braking operation.

Safe, stable, advanced, and intelligent electric control system

Self-developed controller SYMC specially for engineering machinery is configured. The adoption of CAN-bus full-digital network control technology ensures stable control signal, simple harness, and high reliability. Timely feedback of data information can achieve the monitoring of the overall working status in realtime; the load moment limiter equipped with the comprehensive intelligent protection system is used with accuracy within 3% to provide a comprehensive logic and interlock control, thus ensuring more safe and reliable operation.

INTRODUCTION

Superstructure

Cab:

It is made of anti-corrosion steel plate with ergonomic design such as full- coverage soften interior, panoramic sunroof and, adjustable seats etc., and humanized design providing more comfortable and relaxing operation experience. The display of load moment limiter integrates main console and operation display system, which clearly show the data of all operating superstructure conditions for lifting operation.

Hydraulic system:

High-quality key hydraulic components such as main oil pump, rotary pump, main valve, winch motor, and balancing parts etc. are adopted to achieve stable and reliable operation of the hydraulic system. Superior operation performance is guaranteed by accurate parameter matching.
Main valve has flow compensation and load feedback control function, enabling stable and convenient control of single action and combined action under different operation conditions.
Winch adopts the electronically controlled variable motor to ensure high operation efficiency. Max. single line speeds of main and auxiliary winches is up to 115m/min.
Slewing system is equipped with the integrated slewing buffer valve with free slipping function to ensure more stable starting and control of the slewing operation and excellent micro-mobility.
Hydraulic oil tank capacity: 840L.

Control system:

CAN-bus instrument: CAN-bus instrument with a combined intelligent control electrical system is used for easy reading of the traveling parameters at any time. The engine fault warning function is applied to ensure convenient and fast troubleshooting.
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.
Counter weight: Counterweight is 4500kg, no flexible counterweight.

Chassis

Transmission shaft: With optimized arrangement of the transmission shaft, the transmission is stable and reliable. For most optimized transmission, face-tooth coupling transmission shaft is used with large transmission torque.

Brakes system:

Air servo brakes are used for all wheels with dual-circuit brake system applied, engine is equipped with an exhaust brake.
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 adopts bi- directional hydraulic locks to improve safety.

Tyres: 11.00R20

Electrical system: With 2*12V maintenance-free batteries, the crane power can be cut off manually via a mechanical master power switch. The use of a CAN-bus control system can achieve information interaction between super structure and undercarriage.
