What are Some Common Problems in Elevators and How to Avoid Them?

An elevator could be malfunctioning due to worn out sheaves, old operating systems and other issues. Most of the cases of failures of such equipments can be avoided with effective preventative maintenance and inspection. Know about some of the commonest problems in aerial work platform and elevators and the possible solutions to avoid the same.

Power failure

A power quality survey is what elevators need to go through, when there are cases of operating problems or motor failures. Elevators need plenty of power from commercial construction utility systems. Any changes in the voltage of the system can affect the operations of the motor or even lead to potential damage to the lifting equipment system. Infrared inspection is the solution.

Worn Out Sheaves

When the sheaves of work access platforms start to wear out, they make the ropes wear out faster, which consequently increase the wearing down on the sheaves. Thus, there is a cycle of damage for both of the important components. Premature failure of hoist rope can be prevented by replacing or re-grooving of sheaves. Make sure that you check the profiles of the groove and verify the fittings between the sheave and the ropes.

Misaligned motor drive

Shaft alignment is vital at the time of coupling an electric motor to some other piece of equipment. When there is improper alignment, the motor bearings can start wearing down. State of the art laser measuring equipment can help detect Shaft misalignment on a mobile elevated platform and avoid the problem.

Suspended working platforms are necessary for working at a height, but involve quite a few risks for those who work on them. Read and find out about some of the major safety precautions to follow before working on a suspended aluminum scaffolding system.

Tiebacks

In case suspension equipment is supposed to fail, there can be a higher risk of falling down of the equipment. It can pose dangers to the workers who are there on the working platform scaffolding, and also those who work under it. With tiebacks in the right place, such risks can be avoided. The wire ropes should have equal strength to those of suspension ropes. There is no need for tiebacks for outrigger beams, in case they are connected directly to the deck or floor with the aid of bolts.

Fall Protection

Fall Protection equipments are necessary in order to prevent falls of workers on an extendable work platform. A secondary brake needs to be attached to the hoist, to stop a platform and hold it automatically during an emergency. There will be an automatic activation of the mechanical component in case of failure of the suspension wire rope, over-speeding while the platform is being lowered or if the platform inclination surpasses 14 degrees.

Hoists

A suspended platform system’s hoists should be checked prior to use every time, to make sure that they are safe, strong and reliable. The hoists should also be maintained after a few usage cycles, as part of suspended scaffold safety precautions.
