20Y - 43 - 31513 Normal Size Hydraulic Safety Lock

1.product introduction

20Y - 43 - 31513 Normal Size Hydraulic Safety Lock The probability of failure of the excavator due to operation is very small, and the control box cannot be restored to its original position unless the operator operates the safety lever again. This structural improvement of the safety bar eliminates the possibility of excavator failure due to operator error, significantly improving the reliability of the excavator.

3.product feature and application

20Y - 43 - 31513 Normal Size Hydraulic Safety Lock A safety lever system in the excavator cab that prevents accidental lowering of the control box without operating the safety lever and facilitates safer tilting of the control box with a limiter that controls power application/short-circuit. According to the present invention, if the operator tilts the control box to enter or exit the cab, the safety lever system diverts (ie shorts) the power to the control lever or control box.
