The front crane is a kind of crane used to load and unload containers. It is mainly used for container stacking and horizontal transportation in the wharf and the yard. It is required to be flexible and easy to operate, so as to pass through a narrow passage after lifting; It has good stability, high stacking layers, and the utilization rate of the storage plant is also an important indicator to test its performance. The front crane is equipped with retractable and left-right rotating container slings, which can be used for handling 20ft and 40ft containers. Therefore, higher requirements are put forward for the load lifting capacity of the slings.

The lifting oil cylinder and telescopic oil cylinder designed and produced by Zhonghe Electromechanical Co., Ltd. are of special structural design, corrosion resistance, wear resistance and long service life, which meet the requirements of high and high frequency load lifting operation conditions for front lifting.
