Technical Characteristics
It adopts pin-linked non-retractable chassis to obtain stability ofsuperlarge tonnage rigs and convenience of disassembly transportation;and extra-long wheel track makes it more adaptable to variousformations;
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 torealize high and low speed;
The main and auxiliary winches all adopt single-row rope technologythrough which the service life of wire rope is 2~4 times longer than thaof multi-layer rope, and the use cost is lower;
The upper main winch is connected by a pin shaft, which has highconnection strength and is convenient to dismount. The main winchbracket of box-type structure is safe and reliable. The main winch meetsthe M6 working condition and the life of reducer can reach up to10000h;
The hydraulic main and auxiliary systems adopt load-sensitive controltechnology to obtain quick response and good control performance;Intelligent cooling control system reduces energy consumption, makingthe rig energy-saving;
Intelligent auxiliary construction technologies: automatic adjustment ofdrilling mast verticality, automatic slewing positioning, automaticspin-off and rotation of rotary drive;
The chassis is equipped with transport legs, making it easier and saferfor site transfer and transportation.
