Tennis player Juan Martín del Potro was trapped for nearly 40 minutes in one of the Olympic Village elevators during the Rio de Janeiro Games due to a power cut.
The athlete was going down in the elevator when he was surprised by a power cut. The poor signal on his mobile phone allowed him to send a message for help, although he was not rescued until 40 minutes later by the Argentine handball team.
In these types of emergency situations, passengers are rescued in a hydraulic lift without the need for external help. This is achieved thanks to an emergency system integrated into the central unit, through which the lift descends to the nearest level by the force of gravity with the help of a small 12v emergency battery that operates in the event of a power supply failure.
In case of cabin blockage, the hand pump is used. This manoeuvre can be carried out even by non-specialised personnel. It is very safe due to the slow speed of the manual hydraulic lift system, accessible from the ground floor and easy to use.
