Core Functions and Roles

Lifting Drive: Provides stable thrust to lift the rear ripper, meeting the needs of soil loosening operations at different depths.

Descent Control: Enables smooth descent of the ripper, precisely controlling the working depth and avoiding equipment impact damage.

Positioning Support: Keeps the ripper in a fixed position during operation, ensuring uniformity and stability of construction.

Load Bearing: Withstands impact loads during soil loosening operations, disperses stress, and protects the hydraulic system and main machine structure.

Suitable Scenarios

Primarily used with bulldozer rear ripper devices, widely applied in mining, farmland reclamation, infrastructure construction, road construction, and other sites, suitable for heavy-duty conditions such as soil loosening and pre-treatment before rock crushing.

Common Faults and Troubleshooting

Weak Lifting/Slow Speed: Check for insufficient hydraulic pressure, clogged filter, oil pump malfunction, or severe internal leakage.

Oil Cylinder Leakage: Check for aging and wear of seals, cylinder scratches, and piston rod damage; replace seals or repair the cylinder promptly.

Vibration/Abnormal Noise: Check for loose mounting bolts, coaxiality deviation, and air mixed in with the hydraulic system. Tighten connections and bleed the air.

Piston Rod Scoring: Check for impurities entering the cylinder block and uneven installation. Clean the oil passages and correct installation accuracy.
