[0055] (4) Mark the disassembled mechanism and transfer it to the maintenance room.

[0056] The upper skateboard frame can be disassembled either on the maintenance rack or on the platform.

[0057] Thoroughly clean all debris from the frame with a wire brush, and also clean the hydraulic cylinder bracket, blowing it clean with compressed air. Use a 30mm wrench to remove the closing pin, and thoroughly clean the pin and locking sleeve. Use a 6mm Allen wrench to remove the left and right stops;

[0075] The flatness of the mounting surface and the spring force performance are tested by using the flatness testing component 4 and the spring performance testing component 5 respectively to ensure that the parameters of key components meet the usage requirements.

[0076] The cleaning and blowing component 6 removes impurities and dust from the surface of the mechanism to prevent jamming and abnormal wear during operation.
