2. Under 10% overload conditions, the carriages are lifted by 10 degrees and 20 degrees respectively for 5 minutes. The self-reduction rate of the carriage shall not exceed 2.5 degrees. The carriage shall meet the following requirements: the surface of the carriage shall be flat and the outer surface shall not allow obvious Rugged; there is sufficient rigidity and strength; the length of the carriage is allowed to differ by 8mm, and the straightness and parallelism of the two beams must be controlled within 3mm; the difference between the two diagonals should not exceed 10mm. The between the base of the car and the chassis of the car should be Fit, the unsuitable distance caused by deformation shall not exceed 6mm; the rear compartment panel and the rear end of the compartment shall be fitted together, the maximum clearance is less than 3mm at the upper end and less than 1mm at the lower end; the locking mechanism is flexible to open and reliable to lock. .
