The emergency lowering: Function and location of the emergency lowering

In our last post, we looked in detail at the safety devices on aerial work platforms . Today, we will focus on a particular aspect of these safety devices: the emergency lowering mechanisms. These are crucial for the safe and controlled lowering of the aerial work platform in the event of a malfunction or emergency.

In this article we explain how the emergency lowering on aerial work platforms works and why they are an essential element for safety when working at height. We look at the different types of emergency lowering mechanisms.

The Functioning of Emergency Lowering Systems

Mobile aerial work platforms must be equipped with a higher-level emergency control system (e.g. hand pump, second power supply, emergency lowering valves) which, in the event of a failure of the main drive power, ensures that the work platform is returned to a position from which it can be safely abandoned.

The work platform must be able to avoid any obstacles. The emergency control system must be able to be operated from a location that is easily accessible from the ground.

These systems represent an important safety device for the safe lowering of the work platform in the event of a failure of the drive system or other critical components and are used in various types of work platforms. They are used for the controlled lowering of the work platform in the event of a failure of the drive system or in other emergency situations. This allows the operator in the work basket to leave the platform safely.

The way emergency control systems work can vary depending on the type of platform, but their purpose is always the same: to lower the platform safely in an emergency. These systems are usually easy to identify and operate in order to respond quickly in an emergency

When and how are emergency controls for work platforms used?

The aerial platform emergency lowering is used in situations where safe descent is required but normal lowering is not possible. For example, when the aerial platform's normal drive does not respond. Another scenario is when an operator on the aerial platform requires medical attention and must be lowered quickly.

All SYSTEM LIFTS can be lowered from the control station or other control points using the emergency lowering system. The operator must be familiar with this safety device, and colleagues at the site should also be informed of it for the safety of the operator in the work basket.

ATTENTION: Danger of tipping over if operated incorrectly!

Where can the emergency release be found?

The emergency lowering on work platforms is in most cases easily accessible and clearly marked. Find out where it is before starting work. The operator is informed of the exact location of the emergency lowering in the operating manual and during the briefing. The location may vary depending on the model and manufacturer, but the emergency lowering is usually in a clearly visible place near the control panel or control station.

Do not confuse the terms: The emergency stop switch stops the platform, the emergency lowering lowers the platform. In the picture you can see: above emergency lowering (green), emergency stop switch (red) - manufacturer Niftylift

What happens after the emergency lowering? Can the platform continue to be used afterwards?

After using the emergency lowering device on a work platform, it is essential that the machine is inspected and serviced before it is put back into operation.

After using the emergency lowering, the following measures must be taken:

1. Switch off the machine or press the emergency stop button to stop all further movements.
2. If you rent a work platform, please report the activation of the emergency lowering to the lessor.
3. If you have your own work platforms, you should check them for damage, especially to the hydraulic components as well as the battery, pump and other safety-relevant parts.
4. Have the platform serviced and repaired according to the manufacturer's instructions.
5. The platform can only be safely put back into operation after successful maintenance and inspection.

To avoid accidents and injuries, it is extremely important not to take any risks and ensure that the aerial work platform is fully functional and safe before putting it back into operation.
