Lift Technology

The main cable shows wire breaks, the strength to bear a fully loaded lift car is no longer assured.

As a result, the main cables to which the lift is attached may tear.

If this would be the case, the lift car would drop a little and be braked by the safety gear in the shaft, as soon as the lift builds up overspeed.

According to standards, the lift car roof is to be designed to be safe to walk on.

As can be seen from the bent cover, this is no longer the case for this lift system.

Even worse is the layout of the cabling, which could cause a person to stumble, resulting in a fall down the lift shaft in the worst case Scenario.

You can see here that the track is distorted by loose screws or by the natural lowering of the building. In the worst case, the deformation could lead to the counterweight jumping out of the guide and leaving a weight of approx. 1 ton hanging in the shaft, which could cause a lot of damage, right through to severe injuries.

A collision of the counterweight with the lift car could lead to a lot of damage, right through to severe injuries.

In the event of overspeed (right through to falling), the speed limitation device triggers the catch gear and the lift car is stopped in the shaft. This speed limitation device shows on the operating groove (the right-hand side groove without cable) an impression of the steel cable that is normally there. Normally, the cable touches the branches of the cable groove only laterally. Here, the cable is already touching the bottom of the cable groove, which could lead to an incorrect triggering speed, and, in case of deployment, to delayed triggering (= higher speeds): personal injury of the people in the lift are the result.

The cable impressions in the operating groove cause a lot of friction due to the incorrect surface quality, which could lead to damage to the catch rods in the event of triggering. (Note: The triggered speed limitation device of the catch gear is actuated by the catch rods, which should prevent a fall.)

Corrosion on load-bearing components of lift parts could have unimaginable consequences.

Even if the rusted lift car shell holds up in normal operation, this does not mean that the parts would not tear and fall apart in the event of an increased load, e.g., trip to the impact buffer, use of the safety catch, ...

A misplaced shaft head fan results in poor ventilation of the lift shaft and also a poor atmosphere in the lift car.

And in the case of fire smoke gases cannot be directed out of the shaft. Many lifts are not connected to life-saving fire detection systems and do not evacuate according to ÖNORM EN 81-73:2005, which means that people who flee the fire by lift could suffer smoke inhalation, which can sometimes have fatal consequences.

If, however, these parts are not correctly attached (as in this case), a planned emergency rescue of trapped people, who are often very scared, can be significantly delayed.

Shows the area between an old lift car door and the shaft door mesh, which was subsequently added. Here, the protection gap is incorrect after installation. In 2002, a fatal accident with a small child occurred in Vienna due to a gap being to large.

Possible consequences of a power unit with oil loss are poor lubrication of the drives and thus drive damage, and of course also ecological consequences if the oil leaks into the Environment.

Numerous measurements are made with precisely calibrated devices, for example of the closing forces of automatic doors, trigger speeds of speed limitation devices, or the effectiveness of electrical protective measures.

High level of qualification, continuous training, integrated lift inspection

The extensive expertise of lift inspectors requires a high degree of knowledge. TÜV AUSTRIA lift inspectors are HTL (secondary technical school) or university graduates and have at least 2 or 3 years of practical training in the area of lift construction and lift inspection, which will continue to be developed to the current state of the art with mandatory ongoing training. (Note: University graduates can obtain state authorization already after 2 years)
