Bottom side of container spreaders locks are used for lifting without top container, with wire rope sling can complete hoisting working: 40t crane loading and unloading of container spreaders, the spreaders with light weight, no power, easy operation, less investment. The container spreader are available in 32t - 20 feet and 40t - 40 feet.

 

Loading container: first of all put the four main raw steel wire rope sling and a switch to elastic rope under the crane hook, pointer to open before assembly direction, using the sling four side positioning device and driver skilled operating skills, put the turn lock into container of the four corner, and then slowly lifting hook, elastic rope tension first and pull the steering mechanism make the turn lock is rotated 90 degrees to the closed state, continue to improve hook to lift the container.

 

Unloading container: after container spreaders hanging to a predetermined position, make the hook continues to fall 1 -- 2 m, and then to improve hook in the main force before hoisting wire rope to make the turn lock wire rope pulling back to the open position, continue to improve hook can make container spreaders sling and separation, complete an operation.

 

Maintenance: the connecting rod and steering mechanism of the hoisting gear should be opened frequently, and the lubricating oil shall be added to make the parts rotate flexibly, if the hoisting tools and steel wire rope and other obvious damage deformation should be stopped.                                      

 

Container spreaders are usually made of high strength steel structurally as a steel frame, the four corners with twist lock and a guide, the upper is equipped with wire, with hydraulic drive, mostly by the cab control. It has been found that the equipment of the container crane terminal is more advanced, and its operation efficiency depends on the container lifting equipment. Price is usually $200000 container spreaders once failed, not only the entire $5 million, or even tens of millions of dollars of container crane or large gantry crane immediately paralyzed, and port congestion will appear. The top priority of the container handling equipment manufacturer is to improve the operation speed of the hoisting container, ensure its safety, reliability, easy maintenance and minimize the recovery rate, etc.

In transportation and placement of container spreaders, must be put in the spin lock from the ground at the top of the bracket or block, in order to avoid the lift, spinning top friction with the ground and hinder the spinning rotation, resulting in damage of transmission mechanism.
