Technical Characteristics
The telescopic crawler chassis with swing legs is adopted to meet the stability oflarge tonnage drilling rig and the convenience of disassembly and transportation, itis equipped with large diameter slewing bearing with stronger anti overturningability;
The power head adopts vertical pin shaft connection type power box and bracket,which has high reliability and is convenient to disassemble; the power head hascommon mode, rock entry mode, medium speed rock entry mode and energy-savingmode, and users can select corresponding modes according to different geologicalconditions, which improves construction efficiency and reduces fuel consumption;
The main winch adopts single row rope, the service life of steel wire rope is 2~4times longer than that of multi-layer rope, and the use cost is lower;
The main and auxiliary hydraulic systems adopt load sensitive control technology,with fast response and good control performance, the double overhead coolingsystem is adopted, which can intelligently adjust the cooling capacity according tothe temperature, with strong cooling capacity, energy saving and noise reduction;
Equipped with Cummins 15 L electronic control turbocharged engine, it has strongpower, low fuel consumption, convenient and fast service, and adopts decentralizedindependent cooling system, with strong cooling capacity and low noise;
The intelligent control system realizes the functions of automatic adjustment anddisplay of drilling mast verticality, automatic spin-off (adjustable frequency),cruisecontrol, stepless pressure adjustment, bottom touch protection, etc, it adopts buspanel design to prevent misoperation, it is equipped with 12 inch touch screendisplay and electric control handle to achieve better control performance.
