Further, the second rewinding assembly includes a second rewinding box 7 installed on the lower part of the rear end of the boom 2. A second rewinding roller 8 is rotatably installed on the inner side wall of the second rewinding box 7. The power input end of the second rewinding roller 8 is connected to the power output end of a second motor 6, which facilitates the rewinding or unreeling of the second steel rope 10. Further, the sliding assembly includes a fixed sliding seat 21 fixedly installed on the lower part of the front end of the boom 2. An outer sliding sleeve 22 is slidably connected to the outside of the fixed sliding seat 21. A fourth transition roller 14 is fixedly installed on the lower part of the outer sliding sleeve 22, which enables the fourth transition roller 14 to slide smoothly. Further, the linear displacement driving assembly includes a threaded rod 18 rotatably installed on one side of the front end of the boom 2 through a mounting shell 17.

When it is necessary to hoist a short object, the external power supply is supplied through an external switch to turn on the third motor 16 and control the third motor 16 to rotate forward to drive the threaded rod 18 to rotate clockwise. The fourth transition roller 14 is driven through the threaded sleeve 19, the bearing 20 and the connecting piece, and its outer sliding sleeve 22 at the top slides forward along the fixed sliding seat 21 at the lower part of the front end of the boom 2 until it reaches the target position, shortening the distance between the two hooks. When the object to be hoisted is long, the third motor 16 is controlled to rotate in reverse, and the principle is the same (the first motor 5, the second motor 6 and the third motor 16 are all existing products on the market).
