Low Pressure Crawler Drilling Rig

The KG910B/D/E, KGH3 low pressure crawler drilling rig is the modified version of our KY100J type drilling equipment. A variety of improvements have been made to get better drilling performance. First of all, this product is an ideal borehole drilling machine with very great structure and working performance. The updated parts include hydraulic system, walking parts and gyrator.

KG910B: The power of the YC2108 (33KW, 2200r/min) is stronger, and the rotation speed and propulsion speed are both faster. Besides, this kind of motor has better stability and longer service life.

Advantages of KG910B over KY100(D)

KG910B KY100 Advantage
Power YC2108 YC2100
Walking parts Motor and reducer Ball piston motor (direct connecting) Less pressure and longer service life for the motor
Walking pressure 11Mpa 14-16Mpa
Rotation motor Cycloid motor Steel ball motor Longer service life
Rotation speed 105r/min (diesel engine 1700r/min) 120r/min (diesel engine 2200r/min) 70r/min (diesel engine 1700r/min) 50% higher rotating speed
Hydraulic system 25 pumps, fast rotation and lift group valve, new type flow divider 16 pumps Increased flow
Feeding speed 390mm/s 280mm/s 40% higher feeding speed

KG910E: The KG910E low pressure crawler drilling rig adopts both electric motor and diesel engine for the hydraulic pump of hydraulic system. The electric motor and diesel engine should be used separately. When you use it as an electric drilling machine, the machine’s working noise is lower, and the other advantages include good eco-friendliness, high safely level, and low using cost. As a set of premium hybrid electric construction equipment, however, if there is no extra power supply, it can be shifted to diesel engine driving mode for long distance drive.

KGH3: A dry type dust collecting device and speed reducer are added. The dust collecting device consists of a prefiltering device and a fine filtering device. The eco-friendly, high-performance filtering material leads to high purification efficiency (99%).
