The invention relates to the technical field of telescopic boom forklift trucks, in particular to a telescopic boom forklift truck landing leg control method and a telescopic boom forklift truck. The control method for the supporting leg of the telescopic boom forklift loader comprises the steps that when the telescopic boom forklift loader works, the load weight on a pallet fork and the actual length of a boom frame are detected, and whether the actual length exceeds the safety range of a first load curve or not is judged according to the load weight and the first load curve of the supporting leg in the contraction state; when it is detected that the actual extension length exceeds the safety range of the first load curve, whether the actual length exceeds the safety range of a second load curve or not continues to be judged according to the load weight and the second load curve in the landing leg contraction state, and if not, the operation speed of the telescopic arm forklift loader is controlled to be reduced or operation is stopped. And the walking function of the telescopic arm forklift loader is closed, and the supporting legs are controlled to stretch out. The supporting legs can automatically stretch out, the working efficiency of operators is improved, and meanwhile the safety of man-machine operation is improved.

    本发明涉及伸缩臂叉装车技术领域,尤其涉及一种伸缩臂叉装车支腿的控制方法及伸缩臂叉装车。伸缩臂叉装车支腿的控制方法包括:伸缩臂叉装车进行作业时,检测货叉上的载荷重量以及臂架的实际长度,并根据载荷重量和支腿收缩状态下的第一载荷曲线判断实际长度是否超出第一载荷曲线的安全范围,当检测到实际伸长长度超出第一载荷曲线的安全范围时,则继续根据载荷重量和支腿收缩状态下的第二载荷曲线判断实际长度是否超出第二载荷曲线的安全范围,若否,则控制伸缩臂叉装车的作业速度降低或停止作业,并关闭伸缩臂叉装车的行走功能,并控制支腿伸出。本发明能够实现支腿的自动伸出,提高了操作人员的工作效率,同时提高了人机作业的安全性。
