The electromagnetic fixing block 5 is used to electromagnetically adsorb and fix the electromagnetic adsorption block 501. The safety rope 502 is used to connect and fix the waist belt 503 and the shoulder strap 506. The control button 505 on the control block 504 is used to control the electromagnetic connection, adsorption and separation between the electromagnetic fixing block 5 and the electromagnetic adsorption block 501, which makes it more convenient to protect the operator's safety during movement.

[0045] In practical use, the invention first activates the first motor 201 within the first fixed block 2, driving the rotating rod 202 to rotate and open the railing 203 and the moving rod 204, allowing the worker to enter the tower crane. Then, the railing 203 and the moving rod 204 are rotated to close. Next, the third motor 307 within the third fixed block 306 on the fixed climbing rod 3 is activated, driving the rotating pedal 4 to rotate to a horizontal angle. The worker then puts on the waist belt 503 and shoulder strap 506. The electromagnetic adsorption block 501 is then adsorbed onto the electromagnetic fixed block 5 on the side wall of the moving ring 305. The worker stands on the rotating pedal 4, placing their feet on the anti-slip protrusions 402 of the anti-slip mat 401, and then slips their feet into the fixed ring 403. Next, the second hydraulic rod 304 within the second fixed block 303 is activated, moving the moving ring 305 upwards and thus the rotating pedal 4 upwards to a designated position. The worker then stands on the next rotating pedal 4. When the foot is on the fixed step net 302... Press the control button 505 on the control block 504 to separate the electromagnetic fixing block 5 from the electromagnetic adsorption block 501. Then, the electromagnetic adsorption block 501 is adsorbed onto the next adjacent electromagnetic fixing block 5. Then, you can continue to move to the next rotating platform 108. After the operator has climbed up, start the third motor 307 to drive the rotating pedal 4 to rotate to a vertical angle to prevent non-operating personnel from climbing onto the rotating platform 108 using the rotating pedal 4. Then, the operator can enter the cab 109 to operate the equipment. The rotating platform 108 rotates to drive the balance arm 112 to rotate to a specified angle to lift the material. The fence 110 provides safety protection for the operator when exiting the cab 109. After a period of use, the anti-slip mat 401 will wear out. Remove the anti-slip mat 401 from the rotating pedal 4 and then attach the new anti-slip mat 401 to the slot 404 with the snap-fit ​​block 406. Then, it can be used again.
