伸缩臂叉车是一种新型多功能物料搬运设备 ,其货叉平动与否直接影响作业的安全。作业时 ,货叉随着伸缩臂俯仰角的变化而改变 ,为避免物资滑落等事故发生 ,需对货叉等进行调平控制。本文介绍了调平机构优化及误差分析方法。 Telescopic forklift is a new multi-functional material handling equipment, the fork translation or not directly affect the safety of operations. During operation, the fork changes with the change of the pitch angle of the telescopic boom. In order to avoid accidents such as material falling off, the fork and the like need to be level-controlled. This article describes leveling mechanism optimization and error analysis methods.
