With the development of economy and the exchange of overseas trade, wharf economy becomes more and more important. In the past, the wharf relied on manpower, but in order to improve efficiency, the application of mechanical equipment is more and more, the common Marine crane, dock fixed crane, the handling of goods has an important role, to promote the development of the economy. What factors are related to the hoisting of wharf fixed crane?

1. Quality of crane. Choose high grade crane is premise, the quality of crane is good ability ensures the safe that condole installs.

2. Voltage: the voltage of general wharf cranes must be stable, which is different from that of general power consumption. If the voltage is unstable, the motor will not run smoothly and the hoisting component will be cut down. Generally, the design rated voltage of lifting motor is 220v plus or minus 5v.

3. Diameter and length of wire rope. These elements are often overlooked. If you choose diameter thick steel wire rope or length is long, can form drum diameter to increase, because the rotational speed of motor is certain, certain cause rotate speed to accelerate, and cause crane strength to cut, lift component to cut.

4. When hoisting, the Angle between the inclined arm and the column should be controlled within 45 degrees. The less the Angle, the better.

5, the maintenance and maintenance of the crane, such as, in the appearance of the treatment, the need to clear the surface of the components, painted with anti-rust paint and decorative paint film. In the lubrication, the lubrication of the internal equipment is very important, is one of the important factors affecting the efficiency and safety.
