我厂检修车间经常装配几十公斤重的部件,使用吊车吊装很难对正。过去用人力抬起安装,劳动强度大。我们设计了平衡吊具(图1),工作原理是重物与平衡块重量相等,因此使用这种吊具可用较小的力,使重物在一定范围内灵活升降。使用时吊环1挂在吊装设备上,较大高度的起吊由吊车完成,安装找正时,小范围的调整,由人工推压部 Our factory repair shop often assembled dozens of kilograms of heavy parts, the use of crane lifting is difficult to correct. In the past, using human lift installation, labor-intensive. We designed a balance spreader (Figure 1). The working principle is that the weights are the same as those of the balance weight. Therefore, the spreader can be used with a small force to make the weight move up and down within a certain range. When used, the hoist ring 1 is hung on the hoisting equipment, the hoisting of a large height is completed by the hoisting crane, and the installation is adjusted and adjusted in a small area,
