KG910E type drill rig by electric motor and diesel engine combined drive the hydraulic pump to provide motives for the hydraulic system. Crisscross use electric motor and diesel engine, in the absence of the power converter using diesel engine, convenience users for a relatively long distance movement and transitions, Under the condition of power use electric motor with safe environmental protection, low noise, using the characteristics of low cost.

Dynamic condition: Main power: electric motor   Y180L - 4 22 KW / 1470 RPM

Vice motivation: diesel engine CFZS1125GM 18.4 KW / 2200 RPM

Walking components: Ball plug the motor + planetary gear reducer, increase climbing ability, reduce the working system pressure, from 15 mpa to 11 mpa, increase walking motor’s life.

Hydraulic system: adopting the large displacement gear oil pump, improve the rotary speed, up to 120 r/min, the fast rotating/fast lift valve group, change to new diverter valve.

Gyrator: Using cycloid motor with high torque motor at low speed to instead of steel ball motor, improve the motor life; Air intake isolated with revolving shell, prevent compressed air through revolving shell and motor into the fuel tank.
