Used XCMG GR200 Grader with Good Condition

Product Introduction

XCMG GR200 grader is one of the GR series graders produced by XCMG.  GR series graders are mainly used for large-area ground leveling, trenching, slope scraping, bulldozing, loosening, snow removal and other operations in roads, airports, farmland, etc. It is a necessary construction machinery for national defense projects, mine construction, urban and rural road construction, water conservancy construction, and farmland improvement.

Product Features

1. New exterior design

2. The articulated frame is used to cooperate with the front wheel steering, so the turning radius is small and the maneuverability is flexible.

3. Electro-hydraulic control power shift transmission with 6 forward gears and 3 reverse gears.

4. It adopts international supporting hydraulic parts, which is reliable in operation.

5. The action of the blade is fully hydraulically controlled.

6. The rear axle is a three-stage drive axle equipped with a self-locking differential.

7. On-load slewing technology, efficient operation, energy saving and noise reduction.

8. Adjustable console, seat, joystick and instrument layout are reasonable, easy to use, and improve driving comfort.

9. The XCMG special cab is equipped with a wrap-around heating and cooling air conditioner, and the interior column is soft-packed, making driving more comfortable.

10. Front bulldozer, rear scarifier, front rake and automatic leveling device are optional

Tips:

When the cylinder pressure is low and the engine power drops, the output power cannot be transmitted to the drive system through the transmission system as required, resulting in weak driving of the motor grader.

Pistons, piston rings, and cylinder liners are worn out, which will cause the loss of compressed air in the cylinder, and the cylinder pressure will drop when the compression ends; at the same time, high-temperature gas will leak into the crankcase along the cylinder wall during combustion, resulting in power loss. Pistons, piston rings, and cylinder liners are worn , generally accompanied by the phenomenon that a large amount of smoke is discharged from the exhaust port of the crankcase. In addition, the valve seal is not tight or the cylinder head gasket is damaged, which will also cause the cylinder pressure to be low. Use a diesel engine cylinder pressure gauge to measure the cylinder pressure through the injector hole. If the compression pressure is generally lower than the specified minimum value, it means that the sealing performance of the engine cylinder is poor; if the pressure difference between the cylinders exceeds 10%, it means that the cylinder with low pressure is poorly sealed; if the compression pressure of two adjacent cylinders is low, it means that the cylinder Pad damage, gas blow-by in two adjacent cylinders The normal cylinder pressure of Shangchai D6114 diesel engine is 2000kpe– 2500kpa, and the range of compression pressure of each cylinder should be less than 10%.
