Description
power system
Equipped with Isuzu high-power diesel engine, the power reserve is sufficient, the continuous output is stable, and the power does not decay during continuous drilling conditions, making it suitable for long-term high-intensity pile foundation construction.
Power head configuration
Equipped with a multi-stage speed regulating power head and a dual buffering and shock-absorbing structure, it effectively buffers rock impact. The service life of the reducer and motor is greatly improved, and it can stably handle pebble layers and moderately weathered rock layers.
hydraulic system
Adopting load sensing hydraulic control, torque, speed, and pressure are automatically matched, resulting in smooth composite action, reducing ineffective energy consumption, and stable long-term construction fuel consumption control.
