With the development of the economy and the exchange of overseas trade, the terminal economy has become more and more important. In the past, the terminal relied on manpower, but in order to improve efficiency, more and more applications of machinery and equipment, such as marine cranes and dock cranes, have an important role in the handling of goods and promote economic development. What are the factors related to the lifting of dock cranes?

1). The quality of the crane. The choice of a quality crane is a prerequisite, and the quality of the crane can ensure the safety of the lifting.

2). Voltage, the voltage of the general terminal crane must be stable and separate from the general electricity consumption. If the voltage is unstable, the motor will run poorly and the lifting component will be reduced. Generally, the rated voltage of the lifting motor is 220v plus or minus 5v.

3). The diameter and length of the wire rope. These elements are often overlooked. If you choose a wire rope with a large diameter or a long length, it will form an increase in the diameter of the drum. Since the rotation speed of the motor is constant, the rotation speed will be accelerated, and the strength of the crane will be reduced and the lifting component will be reduced.

4). When hoisting, the angle between the inclined arm and the column is optimally controlled within 45 degrees, and the smaller the angle, the better.

5). For the maintenance and maintenance of the crane, for example, in the external treatment, it is necessary to clean the surface of the component, coated with anti-rust paint and decorative paint film. In terms of lubrication, the lubrication of internal equipment is very important and is one of the important factors affecting the efficiency of use and safety.
