[0134] The best material for the base plate is aluminum alloy.

[0135] Mass: The overall mass is less than 1.5t.

[0143] The operator activates the electric hook of the towing device (9) via remote control to hook the flatbed trailer with the towing device.

[0144] The ball joint at the rear of the vehicle is precisely aligned. After coupling, the operator must manually confirm that the mechanical lock pin is engaged.

[0145] Whether it is fully inserted, check the reading of the hook pressure sensor on the instrument panel (standard range: 5-8 MPa).

[0146] To retract the front wheel jack mechanism (11), press and hold the "Retract" button on the remote control.

[0147] The top and bottom laser positioning devices automatically scan the ground flatness. When the tilt angle is ≤1.5°, the hydraulic cylinder...

[0194] Step 10: Unloading at the destination

[0195] When unloading, the reinforcing devices should be removed first, and the operation sequence is a mirror image of the loading sequence. Pay special attention to electrical safety.

[0196] The wire rope release of the winch mechanism (10) needs to maintain a constant tension (50-80kg) to prevent the drone from slipping.
