Features
Tracked chassis
Equipped with a wireless remote control crawler chassis, it is suitable for various terrains, and the drilling rig can be controlled within a safe distance to prevent sudden danger.
Frame
The frame of the welded structure is welded on the crawler chassis, which can improve the rigidity of the carriage and the stability of drilling when the carriage is erected.
Carriage
The carriage with coal connection structure adopts hot-rolled carbon channel steel and square steel as the guide rail of the power head, and controls the oil cylinder to rise and fall smoothly through the one-way throttle valve.
Drilling rig & Rotary mechanism
The drilling tower adopts the touch-to-ground base to touch the ground and fix it.The rotation of the power head is driven by an axial plunger pump and an inclined-axis plunger motor.
Hydraulic gripper
The oil cylinder chain double-speed feeding mechanism is adopted, the movement is stable and reliable, and it is equipped with a lateral translation mechanism of the power head
Hydraulic gripper
Realize the clamping of the drill pipe and cooperate with the removal of the drill pipe.
Hydraulic hoist
The hoist driven by a hydraulic motor can flexibly lift drilling tools or auxiliary tools.
Hydraulic outriggers
Four hydraulic outriggers quickly level the rig, and hydraulic locks prevent jack creep.
Console
All control functions are concentrated on the console, which is easy to operate and saves time and effort.
Hydraulic system
The drilling rig is fully hydraulically driven, and the hydraulic system adopts load-sensitive control, with high working efficiency and large torque.
Power system
The power system adopts a large diesel engine, and the national after-sales service is worry-free
Cooling system
Air cooling and water cooling are adopted, and the methods are more diverse, which can ensure the machine to work for a long time.
Customer Cases
Widely used in engineering surveys, environment protection survey holes, ground source heat pump holes, drilling and sampling of dam foundation and grouting,micro-piles and water well holes, etc.
The drilling speed is usually 20-30m/h, more rapid than conventional rotary drilling. Shorter construction cycle and lower labor costs.
The drill hole has high straightness and deviation of less than 1%.
Less environmental pollution, it is a green construction method.
