Elevator Hang-Up: Causes and Solutions

Elevator hang-up is not only a nuisance but also a threat to the safety of users. In this article, we will learn about the causes and solutions when the elevator is stuck.

Causes of elevator hang

Failure in Mechanical System:

Elevators, even if designed and installed with high-quality mechanical components, are not immune to failures due to breakdowns. Components such as cables, tracks, or drives can all experience problems, causing the elevator to be inoperable or to stop working altogether. For example, cables can break, tracks can slip off their tracks, or drives can experience lubrication problems, resulting in elevator malfunctions.

Electrical System Error:

Voltage problems or failures in electrical components are also one of the main causes of elevators not being able to move . Components such as inverters, controllers, sensors, or wiring systems can have problems and disrupt the elevator's operation. For example, if the inverter fails, the elevator may lose its power supply and cannot move normally.

These incidents, although undesirable, frequently occur during elevator use and require timely technical intervention to correct and redesign the system, ensuring the safety and performance of the elevator.

Over Design Weight:

One of the common causes of elevator hang-ups is when the elevator is overloaded with more weight than it was originally designed for. Although elevator systems are calculated and programmed to withstand a certain weight range, when this limit is exceeded, there is a risk of serious damage and failure.

When an elevator is overloaded, the pressure and stress on components such as cables, tracks, and mechanical systems increases significantly. This can lead to problems such as broken cables, track slippage, or drive system failures. Furthermore, overloading also affects the elevator's performance, increasing the safety risk to passengers and causing unexpected problems during operation.

Power Outage or Power Supply Problem:

A sudden power outage or power failure is one of the common causes of elevator failure. When there is a power outage, the elevator's electrical system no longer has a power supply to operate, causing the elevator to stop at a certain floor in the building.

This can happen for a variety of reasons, from a general power outage in the area to a technical problem in the elevator's electrical system. In some cases, power failures can be covered by UPS (Uninterruptible Power Supply) systems or backup generators, but without this protection, power outages can cause emergency situations and threaten the safety of elevator passengers.

Control Software Error :

Software errors in the elevator control system are another possible cause of a hang, causing the elevator to not move or operate out of sync.

This error can be caused by a number of things, including programming errors, software conflicts, or errors during software updates. When a software error occurs, the elevator control system may not recognize control signals or properly execute movement commands.

Failure in Safety System:

A malfunction in the elevator's safety system, such as a malfunctioning emergency sensor, can be a cause of a hang-up. The safety system is designed to detect and respond to hazardous situations such as sensor failure, power loss, or other emergencies to ensure the safety of the occupants.

When the safety system detects a problem, it can activate automatic stop mechanisms to prevent the elevator from continuing to operate in an unsafe condition. This can cause the elevator to stop suddenly or become unable to move, resulting in a stall.

To fix this problem, elevator technicians need to check and replace the faulty emergency sensors, re-check the safety system to ensure proper and effective operation. Performing periodic inspection and maintenance of the safety system is also an important preventive measure to minimize the risk of this problem and ensure the safety of elevator users.

Electrical System Check:

The technician will conduct a complete inspection of the elevator 's electrical system to ensure that there are no problems and that all components are functioning properly. This includes checking the power supply, controls, and control panel to detect and correct any problems that may affect the elevator's operation.

Mechanical System Check:

Next, mechanical components such as cables, sprockets, and drives will be thoroughly inspected to detect and correct problems. The technician will check the strength of the cables, the smoothness of the sprockets, and the correct operation of the drives to ensure that these components are not causing the hang-up.

Using the Emergency System:

In some cases, the emergency system will be activated to minimize the risk and return the elevator to a safe position. This system includes safety mechanisms such as emergency sensors and emergency brakes to ensure the safety of users.

Call a Professional Technician:

If the hang cannot be safely corrected, it is necessary to call a professional technician. The technician will have the skills and tools necessary to identify and repair the problem effectively, while ensuring the safety of the elevator users.

What to do to limit the situation of elevator hanging?

To reduce the risk of elevator breakdown, there are several steps you can take:

Regular Maintenance : Perform regular maintenance on your elevator, including checking and servicing the mechanical and electronic components. This will help detect and fix small problems before they become major ones.

Continuous Monitoring : Elevators should be continuously monitored through online monitoring systems or through sensors to detect any problems early.

Employee Training : Ensure employees are properly trained in elevator use and maintenance, as well as how to handle emergency situations.

Compliance with safety regulations : Comply with safety regulations and standards relating to the operation and maintenance of elevators.

Weight Check : Make sure not to exceed the maximum load weight designed for the elevator, to avoid overloading and damaging components.

Update software and equipment : Ensure that elevator control software and equipment are updated periodically to avoid problems related to software errors.

Safety System Checks : Perform periodic checks of safety system components such as emergency sensors and emergency brakes to ensure they are operating properly.

The level of danger to customers when the elevator is stuck

Passenger Safety: When an elevator stalls, passengers may be at risk of safety. Without safety measures, opening the elevator doors and exiting the elevator can be difficult and dangerous.

Medical Conditions : For people with health problems, such as the elderly or people with disabilities, being trapped in an elevator can cause anxiety, stress, and even serious medical problems.

Trapped Time : If the elevator is stuck for a long time, the feeling of being stuck in a confined space can cause anxiety and fear for passengers.

Mood and Mental Health: In situations where passengers are trapped in an elevator, they are often faced with a variety of emotional and psychological challenges. While not always life-threatening, the stress and anxiety that comes with being trapped can cause significant psychological and mental health issues. Here is a detailed analysis of the mood and mental health of passengers in this situation:

1. Stress and Anxiety:

Feeling Trapped: Passengers may feel confused and out of control when they realize the elevator is stuck.

Safety Concerns: Concerns about the safety of yourself and those around you may increase, especially when the exact cause of the incident is unknown.

2. Insecurity and Fear:

Feeling Uncertain: Not knowing when the problem will be resolved or whether the solution is safe can create feelings of insecurity.

Increased Fear: In some cases, passengers may experience feelings of fear and panic, especially if they have had unpleasant experiences with elevators.
