Working Principle:
　　Rotating spreader is made into upper and lower beams by rotating mechanism, rotating the lower beam through the lifting shaft, rotating gears, motor reducer, etc., so as to rotate the rotating angle of the lifted objects, which is convenient and quick, and saves time, labour and manpower.
　　Working mode:
　　The rotating spreader is divided into beam connection, two-pulley connection, four-pulley connection and so on according to the connection way with the host.
　　According to the type of host and actual needs, users can be equipped with the corresponding connection device.
　　Application of rotating spreader:
　　Rotating spreader as a kind of spreader for lifting containers is mainly used in conjunction with gantry crane (referred to as gantry crane) at the dock site.As the larger weight of the container is standard fixed, and the designed lifting capacity of the gantry crane is usually determined by the sum of the weight of the container and the self-weight of the spreader, so the self-weight of the rotating spreader determines the rated lifting capacity of the gantry crane, which in turn affects the cost of the gantry crane to calculate the efficiency of the terminal operation.
