Does the elevator fall safety device need to be checked regularly

Anti-falling safety device is an important part of construction lift, which should be relied on to eliminate the occurrence of falling accidents of the hanging cage and ensure the safety of the life of the crew. So for safety device factory test is very strict, before delivery by the statutory inspection unit for torque measurement, critical speed measurement, measuring the amount of spring compression, each with the test report, after assembly to the construction lifter for drop test under rated load, and the site to use the elevator must be every three months to conduct a drop test.

The anti-fall safety device (the date on the anti-fall safety device), which has been manufactured for two years, must be sent to the legal inspection unit for testing. So far very few people sent for inspection, some sites even every three months to test a fall test do not do, all think that their anti-fall safety device is not a problem, but once the accident is too late to regret. Why not make regular tests and submit for inspection according to the system? Use units blindly think that if it's not bad, it's good.

In fact, the good or bad of anti-fall safety devices can only be judged by test and inspection, and it is impossible to determine whether they are good or bad in daily operation. For those anti-fall safety devices that have extended service, it is suggested that they should be sent for inspection earlier and tested regularly. Only by knowing well can they prevent malignant accidents from happening.
