Henan Hengyuan Crane Machinery Shipbuilding gantry crane
From the surface conveyors to the manufacturing site. This kind of transportation work must be able to complete the task quickly in the very long transportation distance. Therefore, the determination of the number of cranes is based on the principle that the foundation area of the whole dock can be reached, and each crane does not interfere with each other.
Now the general position of fixed gantry crane, is a fixed pillar tower rotary crane, sports car on the horizontal extended arm on the lower edge. Since this kind of crane is built around the dock, its rotation radius is determined on the condition that it can work in the whole shipbuilding area.
Portal, cross on along the dock laying track, manufacturing and transportation of hull parts. The span of the door: mostly 6 meters. This kind of crane sometimes uses the rotatable prop, sometimes uses the fixed prop, and sometimes also uses the turntable. To change the radius of rotation, the undulating extension arm is usually on the lower edge of the horizontal extension arm, and a sports car is installed to change its rotation radius.
In order to ensure the stability of the crane, it is generally necessary to have a balance weight, which is installed on the underframe of the movable portal support.
