液压操纵平衡吊(图1)是一部装有液压缸的连杆型起重吊,最大吊举能力为750×4公斤·米。它有一部平行四边形连杆,一个垂直导杆,一个水平导杆,能准确无误地将吊物在3×2.5米~2的工作区域内垂直和水平移动;同时刚性臂能防止物件摆动。在端部1(图2)由前进后退油缸拖动时,端部3即水平运动;端部2由上下油缸拖动时,端部3即垂直运动。即吊钩的垂直和水平运动可分别由两

The hydraulically operated counterbalance crane (Figure 1) is a link-type crane equipped with a hydraulic cylinder with a maximum lift capacity of 750 × 4 kg · m. It has a parallelogram linkage, a vertical guide, a horizontal guide, can accurately and accurately move the hanging objects in the working area of ​​3 × 2.5 m ~ 2 vertically and horizontally; at the same time rigid arm can prevent the object from swinging. When the end portion 1 (FIG. 2) is dragged by the forward / reverse cylinder, the end portion 3 moves horizontally. When the end portion 2 is dragged by the upper and lower hydraulic cylinders, the end portion 3 moves vertically. That is, the vertical and horizontal movement of the hooks can be respectively two
