Performance Characteristics
It 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.
It 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.
The 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.
The upper main winch is connected by a pin shaft. which has high connection strength and is convenient to dismount.
The 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.
The hydraulic main and auxiliary systems adopt load-sensitive control technology to obtain quick response and good control performance.
Intelligent cooling control system reduces energy consumption, making the rig energy-saving.
Intelligent auxiliary construction technologies: automatic adjustment of drilling mast verticality, automatic slewing positioning, automatic spin-off and rotation of rotary drive.
The chassis is equipped with transport legs, making it easier and safer for site transfer and transportation.
