The utility model makes a simple improvement to the load-bearing beam body, changes the vertical setting of the car rope head rod to a horizontal setting, and then guides it through two guide shafts, thereby greatly saving space on the top floor of the shaft without affecting the up and down movement of the car. The setting of the two guide shafts causes the load-bearing beam itself to be subjected to a deflection force, ensuring that the force on the wire rope and the wheel is better and more stable.
