Main Technical Performance and Characteristics

Power System

The system adopts turbo-charged diesel engine, with big output torque, big coefficient of power reserve and low oil consumption.


Transmission System

Transmission system comprises torque converter, power shift transmission, drive shaft, rear axle and rear wheels. Transmission and torque converter are electronic-control counter-shaft power-shift transmission. torque conventer has big torque ratio high efficiency and wide high efficiency area. Better combined work characteristics can be achieved when the torque converter is matched with engine. Transmission has 6 forward gears and 3 reverse gears. It has neutral start protection function. Gears will be easily shifted by electrohydraulic control. During gear shift process, there is no impact, speed ratio distribution is reasonable, and various work requirements can be satisfied.


The drive axle applies Meritor rear axle and the rear axle applies balance suspension mode to ensure load is evenly distributed to four wheels in order to facilitate full display of the adhesion capacity. Main transmission of rear axle is installed with "NO­SPIN" self-locking differential when not spinning. When wheels at a side slip, those at the other side can still transfer their original torque. In this way, the machine has enough tractive force under whatever road conditions.


Brake System 

The brake system consists of service brake system {i.e. foot brake) and parking brake system {i.e. hand brake). Service brake applies dual-circuit hydraulic brake system acted to four middle and rear wheels of the grader to render safe and reliable braking. Parking brake system consists of controller and brake.


Frontlxle

Front axle is a steering axle. The axle can swing to left and right. Except front-wheel steering, articulated frame is adopted, which can further reduce turning radius.


Working Device

The working device consists of traction frame, turning circle, shovel blade, angular device, etc. In front of the traction frame, there is a spherical hinge that is hinged to the front end of the frame so that the traction frame may tum and swing in any direction around the spherical hinge. The turning circle bearing installed on the traction frame is able to turn around the traction frame under the driving force of turning drive device that further drives the scraper to turn. There are upper and lower two slide rails at the back of the shovel blade supported in chutes of the angular devices at both sides that slide laterally under the push of side shift oil cylinder of the shovel blade. The shovel blade may change shoveling angle to the extent of front 40° and rear 5°.


Hydraulic System

The hydraulic system of the grader mainly includes three parts:

Working hydraulic system/Steering hydraulic system


Service brake system

Service brake system is a double-loop hydraulic system. It is applied on four rear wheels of the grader. The system comprises gear pump, pilot valve, oil charge valve, accumula­tor and brake cylinder. The system is used for controlling service brake.


Interior Trim Parts and Electrical Installation of Cab

Seal cab is adopted, in which air conditioning system is configured. Its interior trim parts are sleeker compression molding parts, which fully embody the demand of man-machine engineering. The electrical system of the grader comprises dashboard, operation box, wiring harness, testing sensor, all kinds of lamps and driving indicator lamp. The system can be used to control operation of engine and driving of grader, and can be used to control all kinds of lamps, driving indicator lamps, wiper and horn. The system can be also used to monitor engine, torque converter, hydraulic system, brake system, accumulator charging and discharging and all kinds of filter elements, can enable driver to master operating condition of the grader at any time, and can alarm to remind driver when abnormities occur.
