[0020] As shown in Figures 1-4 The front end fixed process cross beam of the frame assembly is shown in the figure, which comprises longitudinal beams 1 arranged in parallel on both sides, and a process cross beam assembly A vertically installed between the longitudinal beams 1. The process cross beam assembly A comprises an upper beam 2, a lower beam 3, a middle beam 4, a long bushing 5, a bolt 6, a nut 7 and a side plate 8. The upper beam 2 and the lower beam 3 are arranged in parallel in the upper and lower positions, the middle beam 4 is vertically arranged in the middle of the upper beam 2 and the middle of the lower beam 3, the side plates 8 are vertically installed at both ends of the upper beam 2 and both ends of the lower beam 3 respectively, the bolts 6 are arranged through the outer side of the side plates 8, the long bushings 5 are sleeved on the bolts 6, and one end of the bolt 6 is fixedly connected through the nut 7 after passing through the side plate 8.
