Because plays a key role in the process of operation, in the whole process, PLC has been widely used in the field of industrial control can control is simple and reliable, so design and production line simulation, based on the PLC control system, the system can improve the production department work enhanced the working efficiency to a certain extent. Electric hoist is one of the main types of hoisting equipment in the production process. It is mainly composed of a speed reducer, running mechanism, reel, hook device, limiter, couplings, conical rotor motor and other parts. Electric hoist can also be called a lift, it is a small lifting equipment. It can be used to raise or lower the object, it can be in the horizontal direction of the lifting and transportation device. In the production process, we can see the electric hoist everywhere. It is a kind of light equipment, simple structure, easy operation and maintenance. The general electric hoist has only a fixed working speed, and its structure is a lifting structure and a moving device. Widely applied to the production of goods on the line. In general, the advantages of electric hoist is simple operation, flexible economy, there is a
