Next, the operator or pipe handling equipment moves the pipe fitting through the gap between the limiting rod 62 and the support rod 77, where it is fixed by the pipe clamp 51. At this point, the pipe clamp 51 is fixed at half the length of the pipe fitting, the limiting rod 62 and the support rod 77 restrict the pipe's rotation in the vertical plane, and the inner wall of the limiting groove 63 restricts the pipe fitting's horizontal movement. Hydraulic cylinder 3 is activated, extending its output end and lifting the hoisting arm 4, thus lifting the pipe fitting away from the ground. The position of the floor-mounted pipe fitting hoisting mechanism is moved via pulley 12, and the pipe fitting follows. This continues until the floor-mounted pipe fitting hoisting mechanism reaches the unloading position. Then, the telescopic end of the hydraulic cylinder 3 is retracted, the lifting arm 4 is lowered, and the pipe fitting is removed from the pipe clamp 51 along the gap between the limit rod 62 and the support rod 77, thus completing the lifting of the pipe fitting.
