W1001(W1002)是早年生产的起重、挖掘机械,机械未设安全限位装置,在作为起重机使用时,往往由于操作不慎,容易引起变幅或吊钩过度,使起重臂或起重吊钩撞伤变形,甚至发生拉断起重钢丝绳及起重机翻车等事故。为此,我们在W1001(W1002)起重机上加装了安全自动限位装置,该装置的特点是当安全自动限位装置起作用时,使各液压操作回路中的液压油自动流向油箱,因此能在发动机不熄火的情况下,切断整机的油路,使各操作自动停止。加装的安全自动限位装置结构简单,
W1001(W1002) is a crane and excavating machine produced in the early years. The machine does not have a safety limit device. When it is used as a crane, it is often due to careless operation, which may easily cause amplitude change or hook overhang, so that the lifting arm or lifting The hook hits and deforms, and even accidents such as lifting the hoisting rope and overturning the crane. For this purpose, we have installed a safety automatic limit device on the W1001 (W1002) crane. The feature of this device is that when the safety automatic limit device works, the hydraulic oil in each hydraulic operation circuit will automatically flow to the oil tank. When the engine is not turned off, the oil circuit of the whole machine is cut off, and each operation is automatically stopped. The installed safety automatic limit device has a simple structure.
