Superstructure

Engine

MC11.40-50/WP12.375E50, in-line six-cylinder water-cooled EFI diesel engine, manufactured by CHINA NATIONAL HEAVY DUTY TRUCK GROUP CO., LTD/WEICHAI POWER, rated power 297kW/l 900rpm/276kW/l 900rpm, max. torque    1900Nm/1000-1400rpm/1800Nm/l 000- 1400rpm, the national V emission standards. Fuel tank capacity : 320L

Hydraulic system

Designed and manufactured by XCMG; Made of high-strength steel Electric proportional variable pump driven by an engine, used fbr lifting, elevating and telescoping operations. A closed pump is used to drive slewing operation.Proportional solenoid valve Air cooled hydraulic oil cooler Oil tank capacity:840L

Gearbox

Mechanical transmission 10JSD180TB, made by Shaanxi Fast Gear Co., Ltd., manual flexible shaft control, 10-forward speed and 2-reverse speed with a synchronizer.

Operating mode

 Pilot electric proportional control is used for controlling the superstructure. Also employed are PLC integrated intelligent control technology and CANBus control network. Besides of normal control function, real-time monitoring, fault diagnostic and fuzzy inquiry of working conditions are available.

Alxes

Four-axle chassis, axles 1 and 2 are high strength load-bearing axles for steering, axles 3 and 4 are steering and driving, made by famous makers through adoption of foreign advanced technology

Main winch system

Hydraulic control is used for speed regulation. The system is driven by a hydraulic motor through aplanetary gear reducer, with a normally closed brake, a balanced valve and a grooved drum equipped.

Suspension

Leaf spring balanced suspensions are adopted fbr front axle, and dual longitudinal arm leaf spring balanced suspensions are adopted for rear axle.

Auxiliary winch system

Hydraulic control is used for speed regulation. The system is driven by a hydraulic motor through aplanetary gear reducer, with a normally closed brake, a balanced valve and a grooved drum equipped.

Tires

8tires and 1 spare tire, each axle is equipped with single tire, manufactured by Double coin, large bearing capacity. Tire specifications:385/95R25

Slewing system

Single-row four-point ball contact external tooth slewing ring is driven by a hydraulic motor ,through a planetary gear reducer, with a normally closed,and may continuously slew 360° □.Power control or free slewing function is available,and the slewing speed may be infinitely regulated.

Brakes

Service braking: foot pedal operated double-circuit air pressure brake. The first circuit acts on the wheels of axles 1 and 2; the second circuit acts on the wheels of axles 3 and 4. Parking brake: air-release brake, acting on the 3rd and 4th axles, it works through the spring-loaded air chamber on each axle. Auxiliary brake: engine exhaust brake and engine retarder brake.

Elevating system

A single cylinder;A balance valve with load compensation function.The newly designed way, which combines external oil pressure-controlled free-fall with the rod chamber pressure-controlled balance valve.

Steering

All-wheel steering, axles 1 and 2 are mechanically steered + hydraulic power assistance, axles 3 and 4 are steered through cylinder control.
