This system through the man-machine interaction interface and various signal sensors，can real-time reflect the arm angle, height, working amplitude, lifting weight, load and other information of the Forklift to the operator,make the operating capacity of the Forklift is safe and effective in the range of design parameters. When the Forklift operation is close to or beyond the safe range.The host computer will send sound and light alarm to remind the operator to stop the illegal operation,if the operator continues to violate the rules,the host computer will send auto lock signal and stop the arm of the Forklift to dangerous direction,so as to avoid the safety accident of Forklift and operator effectively.

2.System constitute

The system consist of one hydrualic pressure sensor,three angle sensors,display and host computer intergrated machine,and mounting bracket.
