Q:Are there any good signs in the construction elevator door
It is forbidden to climb, construction lift operation procedure, limited number of passengers, no power cuts
Q:The staff on the construction platform shall not exceed the number of people
Depending on the actual situation, different quality of platform specifications will affect the number of people manned. Hope can help you.
Q:The construction elevator relies on what to carry heavy, static hour force point where
The driver of the elevator ladder cage is driven by two or three worm gear reducers, which carry heavy lifting parts, and gravity is carried by the rack. At rest, the force point is in the meshing of the gear and rack. It is the main balance between the rewire rope and the ladder cage and the relative motion. For heavy can improve dynamic performance, a heavy on the ladder cage running more smoothly, when a fall, fall of heavy can slow down the ladder cage speed, it should be said that safety performance is better.
Q:How does the construction lift fall without electricity
Pull the manual release (or pedal release) to loosen the electric motor to loosen the brake, the lift will fall, and the speed localizer will die. It's not that professionals don't try "very dangerous"
Q:The elevator is banned from using elevators for more than a class of high winds
According to the safety requirement is level 6, please adopt!
Q:What are the requirements for the construction elevator
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.
Q:What's going on with the decline in construction lift
Check whether the brake contactor and normal, contactor adhesion conditions will decline, brake pads have the problem not only rise to fall, fall in the same slide. If the contactor is ok, you can see that there is a groove on the brake pad, and it is only replaced if the brake is not damaged, such as cracking. If it's a frequency conversion elevator, if you're down, see if the converter has any fault code, if you have a consulting manufacturer. The assumption is that the anchuan frequency converter, which may be a real SE failure, means that the timing error is not normal for controlling the contact of the receiver.
Q:Should a fire extinguisher be equipped in the construction elevator?
A fire extinguisher will be required for the 500kg of manned cargo construction elevators at 500kg or more.
Q:What is the main function of elevator motherboard?
The elevator motherboard is different from each brand, and it functions like a computer motherboard
Q:What procedures and procedures will be required to re-use after the construction elevator overhaul?
Important parts replacement needs to be changed to the qualification, the procedure is like the new ladder, according to the new ladder standard test.
