Its explosion proof property, over speed and over reel control, prevention of high and low hydraulic pressure, and coordination of braking and hoisting are the key and core points for safety design.

Based on the former hydraulic hitch equipment of tractor improve and design of the electronic hydraulic hitch control system, the control core of this system is 80c196kc MCU.

To the hydraulic jack interior module's unique design, after having realized the valve core opens completely, causes the gas free from obstacle passing.
