Hydraulic pump:

Double hydraulic pumps are used. The main pump for vibration, and the small pump for steering. The hydraulic oil without vibration returns directly at low pressure, thus the oil pressure and oil temperature is low.Suitable for long-term operation.

2. Brand engine:

Equipped with Changchai 4g33TC turbocharged engine, the rated power is 110 horsepower, with abundant power, surplus power and stable performance.

3. Hydraulic oil overflow:

Double high pressure overflow and one low pressure return mode are adopted. The constant oil pressure of the steering motor is 16Mpa, and that of the vibration motor is 20Mpa, which exceeds the return oil tank to ensure that the pipeline pressure is normal.

4. Damping block:

The four column load-bearing rubber shock absorber is used to reduce the vibration at four points. The shock absorption is soft, the amplitude is wide, and the vibration force is large. Conventional rollers generally use multiple shock absorbers, generally about 16.

5. Air brake:

This machine adopts air brake, which is characterized by short braking distance and easy operation.

6. Hydraulic torque converter:

Without clutch, it operates at high and low speeds with stepless speed change. Easy to operate with higher efficiency.

7. Wheel reduction axle:

The rear axle is equipped with Tiancheng large wheel side bridge, with wheel side reduction, strong bearing capacity, low failure rate and long service life.

The 8-ton roller is mainly used for the foundation compaction of auxiliary roads, pipeline earthwork backfilling, underground parking lot, rural road earthwork and gravel. Its front steel wheel and rear rubber wheel structure are characterized by strong climbing ability and strong power. It can realize self transfer within 5km range, saving freight costs for users.
