HQR 300Z Rotary Drilling Rig

  • General Arrangement, Dimensions and Transportation Dimension

1. The 300Z rotary drilling rig uses dual-line LEBUS grooves to evenly distribute the load between each layer, extending the service life of the steel wire and improving construction safety.

2. The hydraulic system uses an advanced load-feedback technology. The hydraulic liquid is allocated to different parts according to operation requirements. The key parts (pump, motor, valve, pipe and joint) ensure the reliability, and come from internationally known brands.

3. The crawler can adjust between 3,000 and 4,000mm. Customers can increase the counterweight in order to improve the stability and reliability of the machine.
