Description

Technical Field

[0002] With the development and scale expansion of power plants, the work of installing and hoisting bulk equipment or small equipment has become more and more cumbersome and time-consuming; in the past, the traditional hoisting method mainly used cranes or jib cranes to hoist bulk equipment individually, and assembled and installed them on site on high-altitude steel frames; however, this traditional method has some obvious limitations and difficulties. First, the operation process of the traditional hoisting method is very cumbersome. The crane or jib crane needs to be turned and adjusted many times to hoist and install bulk equipment one by one, which not only wastes a lot of time, but also increases the labor intensity of the staff; secondly, the rotation speed of the crane or jib crane is slow, making the hoisting process more time-consuming; because it is more difficult to operate the crane or jib crane at high altitude, the operator needs to spend more time to ensure the safe hoisting and stable operation of the equipment. In addition, the time cost of the traditional hoisting method is also relatively high. Due to the need for additional manpower input and the use of crane equipment, the manpower and equipment costs have increased; at the same time, the safety risks in the hoisting process also require additional safety measures and monitoring, which increases the safety cost.
