Convenient maintenance of the hydraulic pump group
Gas motor drive hydraulic pump group and placed outside the hydraulic fluid chamber, oil pump and motor using the characteristics of soft connection and are free todismount, make the pump running stable and reliable, and easy maintenance.
Strong propulsion, slewing mechanism
Promote the reducer adopts turbine. Worm drive, push-pull big, can realize self-locking.
Slewing drive adopts high-power wind motor and two-stage planetary gear reducer, torque big, easy maintenance
Centralized control of operating mechanism
Drilling rig design has the advanced hydraulic system and gas circuit system, all actions are centralized control, convenient operation.
Operating hydraulic control valve, which can realize the drill arm lifting, swing and the drilling stand pitching, pivot angle, forward (backward), and other functions, ensure multiple drilling holes and the stability of the drill rig.
Operation the pneumatic control valve, which can realize the opening of the oil pump and boring rig advance (promote), rotary, impact and ensure the high efficiencyof boring rig.
Working mechanism of safety and stability
Low gravity center, large ground clearance, can be easily through the rough road.
Advanced crawler automatic leveling function, not only make drill rig walk stability, and greatly reduced to the ground impact force of to the drill rig, ensure the driving safety.
High power pneumatic motor drive, strong climbing ability, has great traction.
Brake equipment and working operating mechanism adopts the linkage method, make the parking is the brake, so as to ensure the jumbo drilling operations and drive on the slope stability and security.
Normal brake condition Walking control valve separate control left and right crawler move、realize forward、recede and turn to.
