With the widely use of electric hoist, and the continuous improvement and development of modern mechanical design. Innovation is the source of the development of science and technology , which is an important part in the fierce competition. Its a posture and we need to keep it in that way, for example, improving the technical level and quality of products, seeking for the customer demands and meeting customers needs. For the different mechanical designs, the work is also different.

 
In general, the electric hoist stars the lifting motor in the beginning, since the goods reach to the appropriate height, then start the running motor to carry the goods to the designated location, and the traveling trolley walk on the lower edge of the steel girder. It use an electric motor to drive the wheels on both sides of the trolley when it walking. At the same time, with the development and progress of society, its obvious that the development of mechanical industry is the core technology to master. In addition, it should pay attention to the start-up principle about electric hoist.

As you can see from the electric gourd, the walking speed is relatively small, so it is usually not designed with a brake. In order to prevent the weight from falling, an electromagnetic brake is set on the lifting mechanism when the traveling trolley is walking. However, in the early period of the start-up, the start steps can be listed as follow: connecting the power from the beginning and the inside working principle; the rotor speed increases form zero to the rating; and according to the feature of electric block, it has three start-up ways which include full press, series resistor and reduction voltage starting.
