Offshore Crane

Detailed description and introduction of portal crane for 12 ton ship crane wharf fixed ship crane;

Ship crane includes lifting capacity, lifting torque, working range, lifting height, working speed, self weight and other indicators. These parameters indicate the working performance and technical and economic indicators of the crane. It is the technical basis for the design of the crane and the main basis for users to select the crane.

Lifting torque: the product of the lifting capacity of the crane and the corresponding working range is called lifting torque, which is a comprehensive index to measure each operating mechanism of the crane.

The control of marine crane is mainly divided into two aspects: the vertical control to reduce the influence of hull motion and the lateral anti swing of load swing. For vertical control, the commonly used method is to connect the receiving ship through the mechanical structure on the crane ship, and sense its relative motion, so that the change of the length of the lifting rope is synchronized with the lifting motion of the receiving ship, so as to compensate the relative motion of the two ships, and complete the lifting and landing transportation of the load on this basis. This method has special requirements for the mechanical structure of the crane and great restrictions on the lifting quality.

Characteristics of Ship Crane:

1. The turning moment is large, and it can withstand the inclination of the hull, with a comprehensive inclination of 5.38 ° (working condition in standard sea area), or even 8.96 °, and Pu's wind class 6.

2. The built-in oil cylinder is telescopic, which has more reliable performance, and the oil cylinder with plating has better corrosion resistance.

3. The crane is sealed as a whole to prevent being affected by the humid environment, and the internal key parts are well protected to achieve the purpose of corrosion prevention.
