[0036] Here’s how it works:

[0037] Check whether the main beam 1, sliding platform 2, traction machine 5, linkage walking device and other components are firmly installed; check whether the power supply system and communication system are connected properly; check whether the traction rope 6 is tight and undamaged, and ensure that the traction machine 5 is operating normally; turn on the power supply system to ensure that the power supply guide rail 32 and the contact brush 33 in the sliding platform 2 are in normal contact; start the wireless communication terminal 39 to confirm that the system has established a communication connection with the control console; check whether the friction plate 29 of the stop structure can move flexibly, and ensure that the friction plate 29 and the rope plate sleeve can clamp the traction rope 6 to complete the auxiliary braking; confirm that the stress detection patch 40 is working properly and provide real-time feedback on the stress state of the main beam 1;

[0041] Start the vehicle-mounted traction machine 5 and adjust the length of the traction rope 6 through the drive end to ensure a smooth rise of the cargo. The vertical buffer structure of the equipment mitigates the impact on the sliding platform 2 during the cargo lifting process. Raise the cargo to a safe transport or installation height.

[0043] The communication terminal will provide real-time feedback on the current position of the sliding platform 2 and the load, as well as the stress recommendations of the main beam 1, allowing for easy adjustment of operating parameters. When the cargo reaches the designated location, the height of the traction rope 6 is gradually lowered to place the cargo steadily on the ground or the target platform; the cargo's fixing device is released to ensure it is in a safe state; and the lifting beam 7 is raised to a height that does not affect the operation of the equipment.

[0044] Control the sliding platform 2 to return to the initial parking area to prevent the running components on the main beam 1 from being scattered and affecting other working areas; stop the power supply to the main beam 1, confirm that the sliding platform 2 has stopped moving, and slowly retract the traction rope 6 to ensure that it is neatly wound inside the traction machine 5; stop the power supply system of the traction machine 5, cut off the main power supply, turn off the wireless communication terminal 39, and ensure that all electrical equipment is powered off; check the entire equipment for wear or operating failures, and record or perform maintenance if necessary;

[0045] Monitor the main beam stress data fed back by the stress patch at any time; in an emergency (such as equipment loss of control or hoisting slippage), the stopping structure can be activated to clamp the traction rope 6 through the electric push rod 28 to quickly stop the movement of the cargo; regularly check the operating status of the traction machine 5, the wear degree of the linkage mechanism, the anti-rust treatment effect, etc. to extend the service life of the equipment.
