侧面叉车设置的支腿缸,用于叉装作业时支撑地面,以提高叉车的稳定性。侧面叉车支腿缸设置位置如图1所示。支腿液压系统设置的行走保护装置,用于防止在未收回支腿缸的情况下操纵叉车行走,造成支腿缸损坏。本文分析某型侧面叉车行走保护装置存在的问题,并提出改进措施。1.行走保护装置存在的问题经实际使用,发现某型侧面叉车行走保护装置存在以下3个问题:(1)支腿缸动作延迟该型侧面叉车行走保护装置采用连锁缸、双向液压锁对行走挡位电路进行控制。当支腿缸伸出落地时,连锁缸活
Side leg truck mounted forklift cylinder for forklift operations to support the ground, to improve the stability of the truck. Side forklift leg cylinder set position shown in Figure 1. Trip protection device for the hydraulic system of the leg to prevent the forklift truck from operating without retracting the leg cylinder, resulting in damage to the leg cylinder. This article analyzes some problems existing in the sidewalk protection device and puts forward the improvement measures. 1. Walking protection device problems The actual use and found that a type of sidewalks walking protection device has the following three problems: (1) leg cylinder delay action This type of side forklift walking protection device with a chain cylinder, two-way hydraulic lock to walk Gear circuit control. When the leg cylinder extends to the floor, the chain cylinder live
