Used in high altitude operations, climbing and suspension operations, the seat belts, which bear a great load, how to test it? When the length of the safety rope (including the open buffer) is less than 0.5m, the suspension does not simulate the impact of the human hip rings. When testing, the sensors are connected between the connector and the hanging point in series. For the falling impact test of a safety suspension belt with a safety rope and a self-locking device, the sensor assembly should be as small as possible, and the action of the self-locking device should not be affected.

In fact, the safety belt dynamic load test method is not difficult, difficult to understand, before the test, we need to wear the safety belt according to the standard in the test dummy body, simulation head connected with the ring release, to improve the simulation center than hanging point 1m, ensure the suspension point to the release point horizontal distance is less than 300mm through adjusting buckle, belt buckle and buckle frame marker, the release of simulation, and start the timer, 5min, check the safety belt, and record test results; for a new safety belt, according to the product description will wear safety belt in the simulated human body, simulate the connection and release of hip rings for improve the simulation head for rings hanging point level, ensure the suspension point to release the horizontal distance is less than 300mm; the release of simulation, and start time; after 5min, measure and record the deviation mark Slip, observe and record seat belts.

After the test is completed, the test values and results are recorded, and the load resistance of the seat belts is analyzed. Besides these, the impact strength and puncture resistance of the seat belts are also the most important in the test, and we need to pay special attention to them.
