HQR 280D Rotary Drilling Rig

  • General Arrangement, Dimensions and Transportation Dimension

1. The main winch is located at the bottom of the drilling mast to offer the best angle for checking line work. The unique design in the line roll prolongs the service life of the steel line and enhances 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 CAT336D undercarriage and up structure allows the crawler to adjust between 3,000 and 4,300mm. The customers can choose the counterweight and increase the weight to improve stability and reliability.
