Description

Moreover, the precision of horizontal movement is also difficult to guarantee, when hoisting the parts to the specified position accurately, deviation often occurs, which affects the subsequent installation and other operation processes.

[0005] 2. In the vertical direction, the lifting speed of many traditional hoisting mechanisms cannot be flexibly adjusted, when hoisting parts of different weights and height requirements, it is impossible to achieve rapid and stable lifting.
