EN 81-72. Safety rules for the construction and installation of lifts. The challenge.
For elevators with long travel distances, such as the one in this Case Study, the EN81-72 standard requires an emergency evacuation system powered by an auxiliary source.
To meet this requirement, the installation company considered several alternatives:
- Generator set.
- Second power supply from the transformer.
- Battery system (UPS).
- Epic evacuation equipment solution from Epic Power Lifts (e3)
Finally, the Epic Power Lifts emergency evacuation equipment for elevators (e3) was chosen, discarding the others for various reasons.
Emergency evacuation solution specifically designed for lifts. The benefits:
Although any of the four options would have been valid, the installation company finally chose the evacuation equipment for elevators solution (e3) from epic power lifts for the following reasons:
- Specifically designed for elevators.
- Compatible with any control system.
- Compatible with any VVVF drive.
- Minimal maintenance.
- Reduced cost.
- Easy installation.
- Regulatory compliance (EN 81-72 and BS9999).
The generator set was discarded as it involves noise, emissions, space and ventilation requirements, and fuel storage.
The additional power supply required civil works, along with the investment that this implies.
The UPS battery system increased the cost of the system due to oversizing for this application, both in terms of cost and space.
