[0002] The precast beam yard is provided with a beam making area, a beam storage area and a precast beam transportation channel. After the precast beams are demoulded, they need to be transported to the beam storage area through the precast beam transportation channel for parking and maintenance. Usually, a tire-type beam mover is used to lift the precast beams from the beam making pedestal and transport them to the beam storage area for maintenance. However, due to the different layouts of the beam making area and the beam storage area in the precast beam yard, the orientation of the precast beams usually needs to be changed. Generally speaking, the precast beams need to be adjusted to be parallel to the transportation channel. However, due to the large size of the tire-type beam mover and the difficulty in turning, it usually moves back and forth on a fixed route. In addition, the tire-type beam mover takes a long time to turn and requires the cooperation of multiple people, which is not conducive to the rapid transfer of precast beams. The truss crane cannot assist the turning of the precast beams. Therefore, the inventors proposed a production transfer and conveying platform for a precast beam workshop. Utility Model Content
