Many things might cause elevator faults and breakdowns, from worn sheaves to a simple outdated operating system. To ensure smooth and dependable operation, major daily is the first step. However, taking proactive, preventive measures is far simpler than restoring the elevator.
Reducing downtime, comprehensive inspections and periodic lift maintenance may significantly boost productivity and reduce energy usage by up to 15%. Nobody likes long lines or malfunctions, and these warning indicators of an elevator system’s excessive wear and tear may also be expensive. The five typical elevator problems and solutions are shown below.
Power outage is the issue.
Updates to voltage may influence motor operations because elevators use a significant amount of power through commercial construction utility systems, and updates to processes can potentially harm the elevator itself.
Option: Conduct a Voltage Stability Survey
Surveys of the power quality might reveal widespread errors like under and excess voltage. Fuse burning hot is much easier to observe when employing infrared technology, which analyses high-temperature changes to assist spot possible problems before they result in a costly system failure.
Worn Sheaves
Sheaves that are worn output too much wear just on ropes, which makes the sheaves even more worn out. Proper inspection should ideally stop this from happening, but if it does, harm is unavoidable.
Regrooving Is an Option
Checking groove profiles is vital to guarantee a suitable fit between sheaves & ropes because premature hoist line failure may be avoided by removing or regrooving sheaves. You may visually inspect groove wear with the use of magnetic tools available, as well as a straight edge.
Contamination Is the Issue
Dealing tiny metallic particles into oil that occurs with wear causes the elevator system to malfunction. Inadequate lubrication or tattered seals might also obstruct proper operation.
Oil and lubricant Analysis as a Solution
A detailed study should be carried out. It would help to look for certain oil qualities that might point to contamination and engine wear to ensure these contaminations don’t impact the elevator. An excessive amount of bronze, for instance, may indicate that the crown of the gear has prematurely worn down. Or, the high aluminium concentration in a hydrostatic tank may suggest that the pump casing has begun to wear.
Problem: Loud or Dysfunctional Bearings
And over 50% of any engine failures may be attributed to bearing issues, and motor vibrations could cause loud bearings. VFD drives may reduce the amount of energy used by the motor. However, they can also produce standard mode flow, a by-product which raises vibrations to dangerous levels.
Inductive Absorbers Are the Remedy
These currents may be absorbed by an inductive absorber, protecting against failures. Additionally, this absorber ensures that all ground is secure and linked, reducing problems caused by electric noise on the ground that might trip up devices.
Drive Motor Misaligned as A Problem
When some other machinery is connected to an electric engine, shaft alignment is crucial because poor alignment may lead to motor bearing degradation.
Laser Measurement Is the Remedy
Laser measurement equipment or even a straight edge & string may be used to determine the alignment of a shaft. However, purchasing a geared device with such a flange-mounted engine that does not necessitate alignment if the machine is dismantled may remove the requirement for alignment altogether.
A lift provides scheduled preventive elevator maintenance and repairs for businesses and organisations in all sectors.
