A movable control handle is also included, which is electrically connected to the travel motor 15, the lifting motor 41, and the electrical box 111.

[0043] The working principle of this utility model is as follows: When in use, the orchard lifting vehicle is controlled by the operator via a control handle. The corresponding travel motor 15 is activated according to the direction of travel, moving the entire vehicle to the desired installation position. Since there are two travel motors 15, when they rotate simultaneously in the same direction, the vehicle moves forward or backward; when they rotate simultaneously in opposite directions, or when one of them is working, the vehicle rotates in either direction. When the vehicle reaches the designated position, the operator controls the lifting motor 41 via the control handle. This drives the transmission sprocket 45 through the drive sprocket 43 on the lifting reducer 42, thereby rotating the climbing sprocket shaft 46 and the climbing sprocket 48. The climbing sprocket 48 and the tensioning sprocket 49 climb upwards on the lifting chain 23, thus raising the lifting plate 31 to the appropriate position. During the climbing process, the platform guide wheel 33 rolls upwards on the inner wall of the column rail 21, ensuring the stable upward movement of the lifting platform 3 and preventing collisions and friction between the lifting plate 31 and the column. Workers operate on the lifting work platform 3. Depending on the situation, workers can push the corresponding guardrails 39 to both sides by hand. The rollers 37 roll within the slide rails 34, causing the movable pedal 35 to extend from under the fixed pedal 36 along the slide rails 34, thus increasing the workspace. Furthermore, for safety, the two ends of the "U"-shaped guardrail 39 are movably fitted into the telescopic sleeve 310. After the movable pedal 35 extends or retracts to a specific length, the guardrail 39 is locked by the railing lock 311 to prevent accidental extension or retraction of the movable pedal 35. During the locking operation, the operator rotates the lock handle 311-6, causing the eccentric lock wheel 311-5 to rotate around the pin 311-4 on the lock seat 311-1. This rotates the protruding part of the eccentric lock wheel 311-5 downwards, pressing the clamping pin 311-3 downwards. The clamping pin 311-3 then presses the locking pin 311-2 downwards, ensuring a tight contact between the clamping pin 311-3 and the guardrail 39, thus locking the guardrail 39. After the operation is complete, the guardrail lock 311 is opened, and the guardrail 39 is pulled inwards to retract the movable pedal 35. Then, by moving the control handle, the lifting motor 41 is rotated in the opposite direction, controlling the lifting work platform 3 to descend and return to its original position.
