The reach stacker is a kind of crane used to load and unload containers. The number of stacking layers and the utilization rate of the yard are the most important indicators to test its performance. In fact, it puts forward higher requirements on the load lifting capacity of the spreader. At the same time, it is requested to be easy to operate and shuttle between channels flexibly. The lifting cylinders and telescopic cylinders designed and produced by Hengli adopt a special structural design with the characteristics of corrosion resistance, wear resistance, and long life, could meet the high requirements of reach stackers and high frequency load lifting operation conditions.
