Description

The present invention deals with the technical field of lifts for building materials, and particularly relates to safe position fixing equipment for lifts for building materials.

A lift is a large machine that carries out transportation by changing potential energy. For example, elevators, overhead cranes, winches, crane trucks, etc. can all be called lifts in a broad sense, such as tunnel lifts and floodgate lifts. A lift generally refers to a large machine with strong power and lifting power. With the development of the construction industry, lifts are widely applied, and the use of lifts, especially in the transportation of building materials, can greatly improve work efficiency. However, since the lift enables transportation by pulling a flexible wire with a power machine, the lift becomes stable as the climbing altitude changes when using the lift, especially when using a building material lift. It is less vulnerable and, when used fixedly, is prone to shifts and tilts, is extremely unsafe and prone to accidents. The present invention is an apparatus capable of solving the above problems.
