Elevator Problems & Solutions 2017

Are you searching Google for “Elevator Problems and Solutions” while looking for the most common elevator problems and solutions to repair your elevator.
There are plenty of reasons that an elevator may being to malfunction, from worn sheaves to really old operating systems. Our team is ready to help you.
There are plenty of elevator equipment failures that are able to be avoided by using the right maintenance and inspections. Regular maintenance can help to increase productivity with lowered down times, but it can even lower your energy usage by 15%. Read the full post here

Whenever your elevator starts to fail, or there are longer than normal wait times, then it could be a sign of some major wear and tear. High energy use, overheating, and lower power are not always the most obvious issues, but it can cause hidden costs. When you add some simple maintenance to your elevator motor, then your expenses and downtime can be lowered.
Common Elevator Issues

Below are some of the most common elevator issues, and how they can be prevented.

1. Elevator Problem: Worn out Sheaves

The Solution: Sheave Regrooving
If you have worn sheaves, then extra wear is put on the ropes, which causes more wear and tear on the sheaves. This causes more wear and damage for the parts.

To prevent hoist rope failure, you can regroove or replace the sheaves. You need to check the grooves and check the fit between the ropes and sheaves. There are simple tools that use magnetic standards that come with a straight edge to check sheave grooves to make sure that they wear evenly.

2. Elevator Problem: Power Failure

The Solution: Infrared Inspections
When it comes to a commercial elevator, there is a lot of power that is needed. When the voltage for the system is upgraded, this can affect the motor operation and cause damage to the elevator system. If the elevator has a history of motor issues or even failure, then a power quality survey needs to be done.

Using infrared thermography can help to measure big temperature changes while helping to spot areas for trouble before it becomes an expensive system failure. The most common issue is over or under voltage which can be found by doing a power quality survey as well as checking to see which fuses run hot, as these can be found using infrared imaging before motor failure.

3. Elevator Problem: Contamination

The Solution: Lubrication and oil analysis
Once the wear starts to happen, small metal particles get into the oil which causes issues with the functions of the elevator systems. Using the wrong lubrication or if there are worn seals it can cause contamination. Doing an oil analysis can check for various properties that can show contamination or motor wear.

4. Elevator Problem: Noisy bearings and Bearing Malfunctions
The Solution: Inductive Absorbers

Many motor failures will happen because of a bearing malfunction. A noisy bearing is normally caused by motor vibrations. As the frequency drives can help in lowering motor energy, it can also cause common mode current which can cause damage and increase vibrations that can be dangerous and cause premature wear on the bearings from stray currents.

A good solution for this is inductive absorbers such as CoolBLUE which can absorb the currents while protecting the system from a breakdown. You need to ensure that all the grounds are connected as well as secured to minimize issues that could be caused by electrical noise from the ground which may trip the system or cause a false count in the system.

5. Elevator Problem: Misaligned Motor Drive
The Solution: Motor Alignment

When you couple electric motors with other equipment, it is vital that you pay attention to the shaft alignment. If there is a misalignment, the motor bearings will wear down. Using advanced lasers can help to find the right alignment or even misalignment. Another way is to use a string and a straight edge.

As an alternative, you could consider purchasing geared machines that use a flange mounted motor which doesn’t need alignment if there is disassembly.
Troubleshooting Elevator Malfunctions

There are various moving parts to an elevator which makes troubleshooting hard, and not to mention the knowledge that is needed and experience that is required to know how the parts work together. It depends on the elevator system manufacturer, and the building size. Troubleshooting the main issue could be almost like running through an area where people are shooting handguns.

Here are some more complaints made by passengers, and issues that we have seen.

Slower Waiting Times

Whenever an elevator has been used for years, the relays will wear down and the performance gets slower. So, they get less efficient. You will need to have an experienced elevator technician to look at it and let you know if the relays need to be replaced or if you need to replace the whole system.
When the elevator makes a sudden stop, or starts to have abrupt landing
This could be some timing issue, electrical failure and/or faulty electronics. All of these will make the landings rough or traveling in the elevator shifty and jerky.

Elevator is starting to overheat

The chance that your elevator breaks down is increased during the summer, as the drives and control systems may not be cooled adequately, which causes the temperature to go above 100 degrees.

Elevator Power Failures and Sensor Problems

Whenever an elevator has back up generator issues or sensor failures, it can cause the elevator doors to not open and it can keep the elevator from working at all. It is vital that you have your elevator inspected regularly, which is the first step to maintaining a smooth ride and increasing the efficiency of your elevator.

Lower your safety risks, and down time of your elevator, which includes having to replace the whole system. If you are needing assistance to troubleshoot your elevator issues, call us today.
