　　Container spreader is a special spreader for container cranes. Due to the different sizes and weights of containers, the spreader for containers is also different. It can be divided into integral (fixed), replacement, mother-child type, telescopic type and other types. Next, let me introduce it to you:

　　1. Integrated container spreader:

　　It hangs specially made hanging beams on lifting steel wire ropes, and replaces the 20ft or 40ft container special spreader connected to the hanging beams according to the needs of lifting containers, and the hydraulic devices are installed on the special spreader. This special spreader is more convenient than a direct lifting type, but adds weight.

　　The entire operation process of the spreader does not require the use of auxiliary components. It is a purely mechanical operation mechanism. The rotary lock of the spreader bearing beam is driven by an elastic zipper to move the rack to drive the opening and closing of the lock head, making the spreader easy to operate. Improve the loading and unloading efficiency of containers.

　　2. Maternal and child style (main-slave style) set boxing spreader. It is a combined spreader that is composed of two spreaders of different specifications and can be quickly installed and disassembled. The main sling of the master and slave spreader is used in a 20ft container and is equipped with a hydraulic device. The rotary lock is rotated by a rotary lock mechanism. When it is necessary to lift a 40ftft container, it is suspended under the main sling by a rotary lock mechanism, and its rotary lock is driven by the hydraulic device of the sling.

　　This kind of spreader has a simple structure, fewer faults, and is more convenient to disassemble, assembly, and maintenance. It is more suitable for mobile loading and unloading machinery such as container spanners. Reducers usually use horizontal reducers, with gears carburizing and hard tooth surfaces and grinding teeth. The reducer box should have sufficient stiffness to ensure that the deformation caused after loading will not affect the meshing of the gears. The box is welded with steel plates. The reducer should add enough lubricating oil according to the regulations, and oil leakage is not allowed on the joint surface of the box and the cover and the shaft extension end. If leakage is found, check and eliminate it in time. Whether the burrs of the joint surface of the box and the box cover are removed cleanly, whether the roughness of the processing surface meets the requirements, whether the splitting and closing surfaces are flat, and there cannot be gaps after the upper and lower boxes are closed. If the above requirements are met, sealant is allowed to be applied during installation.
