[0036] Clamping Principle: The clamping motor drives the first and second lead screws to rotate synchronously. Different clamping brackets, connected to lead screws with different helical directions, allow the clamping motor to move relative to the two second mounting plates on the left and right sides without changing the direction of the main shaft rotation. This drives the first and second clamping brackets on the windproof locking mechanism to perform the clamping action. The clamping motor's drive is limited by an inductive switch to ensure the windproof locking mechanism can fully clamp. The positioning column is made of high-strength material with an anti-corrosion coating to ensure the stability of the windproof locking structure. The cab is firmly fixed in the corresponding position on the unloader, preventing movement or vibration of the cab due to wind, thus ensuring the safety of the operators.
