[0002] There are two main types of lifting solutions for existing concrete lifting and placing equipment, one is a four-point hydraulic cylinder driven lifting type, and the other is a double hydraulic cylinder traction chain lifting type.

Each hydraulic cylinder pulls two chains, which are arranged at two corner points on one side of the receiving hopper, and a set of hydraulic pump stations are used to drive the two hydraulic cylinders to achieve the lifting action. In order to achieve the smooth lifting function of the receiving hopper, the existing technology requires high synchronization of the hydraulic cylinders, and the hydraulic control is difficult and costly.
