[0051] Then the pipe pile is hoisted to a designated position by the crane 1.

[0052] After hoisting is completed, the brake lever is rotated to make the second end of the brake lever rotate out of the tooth groove of the ratchet wheel 4, the spring 8 pulls the two clamp arms 5 to abut against each other through the upper connecting rod and the lower connecting rod, thereby making the anti-skid pads on the clamp arms 5 abut against each other. Then the second hoisting rope 9 is removed from the pipe pile, the height of the first hoisting rope 2 and the second hoisting rope 9 is increased by adjusting the steel wire rope of the crane 1, and then the crane 1 is moved to the next construction position.
