When gripping a small vehicle, operate the electronically controlled multi-way valve 4 to control the rotation of the rotary motor 2, which drives the rotary bearing 3 to rotate. The rotation of the rotary bearing 3 causes the turntable 6 to rotate, ultimately rotating the gripper 16 to a suitable position. Operate the electronically controlled multi-way valve 4 to control the pitch cylinder 7 to adjust the position of the gripper 16 by tilting it up and down. Operate the electronically controlled multi-way valve 4 to control the extension or retraction of the swing cylinder 9 to fine-tune the position of the gripper 16 again. Operate the electronically controlled multi-way valve 4 to extend the telescopic cylinder 13, thereby driving the extension of the first claw 15. Operate the electronically controlled multi-way valve 4 to extend the clamping cylinder 12, thereby opening the first claw 15. Operate the electronically controlled multi-way valve 4 to extend the clamping cylinder 12, thereby opening the first claw 15. Valve 4 controls the movement of the swing cylinder 9, adjusting the first claw 15 to a suitable clamping position for the small vehicle. By adjusting the clamping of the first claw 15, its retraction causes the tipping mechanism to grip the top of the small vehicle. The extension of the pitch cylinder 7, controlled by the electronically controlled multi-way valve 4, raises the small vehicle. The small vehicle is then moved to a suitable position by the electronically controlled multi-way valve 4. The tilting cylinder 11 extends, causing the small vehicle to tilt at an angle. At the end of the operation, the gripper 16 moves to a suitable position by the electronically controlled multi-way valve 4, retracting the clamping cylinder 12 and extending the telescopic cylinder 13 to release the small vehicle. The rear electronically controlled multi-way valve 4 adjusts the tipping mechanism to keep it in a suitable position. During the movement, the hydraulic pump station 5 provides hydraulic oil to the tipping mechanism to drive its movement. The base 1, turntable 6, pitch boom 8, swing boom 10, and gripper 16 serve as the main load-bearing structure to bear the main force. The base 1, slewing bearing 3, pitch cylinder 7, swing cylinder 9, and tipping cylinder 11 serve as adjustment mechanisms to adjust the position of the gripper 16. The clamping cylinder 12 and telescopic cylinder 13 serve as clamping mechanisms to hold the small vehicle. The first guide shaft 14 serves as a structural component to guide and also acts as a load-bearing element while the clamping mechanism is in operation.
