一.Automotive industry standard Semi-trailer support device QC/T310-1999
1.Static pressure test
1.2 times static load 24h
The load carrying test was 1.2 times of the static load, and the legs were unloaded after being carried for 24 hours.
Each component shall not be damaged and produce residual deformation and shall have sufficient stability.
1.2 times lifting load 50 times
First, do the load-free lifting test 10 times, the lifting should be light and flexible; then load to 1.2 times the lifting load and carry out the lifting test 50 times.
During the lift test, the lifting process should be flexible and work properly, the stroke meets the design requirements, and the handle handling force must not exceed 200N (operating on both sides).
