HFR150 Rotary Drilling Rig
- Drilling Diameter: 2800-4600mm
- Drilling Depth:103-150m
- Engine Power:373-641kW
- Max. Output Torque:400-793KN.m
Features
- 1It adopts pin-linked non-retractable chassis to obtain stability of superlarge tonnage rigs and convenience of disassembly transportation;and extra-long wheel track makes it more adaptable to various formations.
- 2It adopts box-type slewing platform with double large vertical plate, which makes the operation more stable and reliable. The rotary drive adopts Zollern dual-speed reducer with 250 motor to realize high and low speed.
- 3The main and auxiliary winches all adopt single-row rope technology.through which the service life of wire rope is 2-4 times longer than thatof multi-layer rope, and the use cost is lower.
- 4The upper main winch is connected by a pin shaft. which has high connection strength and is convenient to dismount.
- 5The main winch bracket of box-type structure is safe and reliable. The main winch meets the M6 working condition and the life of reducer can reach up to 10000h.
- 6The hydraulic main and auxiliary systems adopt load-sensitive control technology to obtain quick response and good control performance.
- 7Intelligent cooling control system reduces energy consumption, making the rig energy-saving.
- 8Intelligent auxiliary construction technologies: automatic adjustment of drilling mast verticality, automatic slewing positioning, automatic spin-off and rotation of rotary drive.
- 9The chassis is equipped with transport legs, making it easier and safer for site transfer and transportation.
