What are the requirements for the construction elevator
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. For safety device to the factory for two years for safety device (delivery date), must also be sent to the statutory inspection unit to carry on the test, after testing once a year.
Actually good or bad for safety device can only judge by test and inspection in the daily operation is not sure whether it is good or bad, for those who are serving for safety device, or advice for the earlier inspection and regular test, only accomplish know fairly well, to malignant accident prevention rather than cure.
The anti-drop safety device is an important part of the construction elevator, which can be relied on to eliminate the occurrence of the fall accident and guarantee the safety 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. For safety device to the factory for two years for safety device (delivery date), must also be sent to the statutory inspection unit to carry on the test, after testing once a year. So far few inspection, some sites even once every three months to detect don't do drop test, all think that their is no problem for safety device, but once had an accident, repent at leisure. Why not do regular tests and tests? The use of units blindly thinks that not bad is good. Actually good or bad for safety device can only judge by test and inspection in the daily operation is not sure whether it is good or bad, for those who are serving for safety device, or advice for the earlier inspection and regular test, only accomplish know fairly well, to malignant accident prevention rather than cure.
