UNE-EN 81-21:2022

This document specifies the safety rules related to passenger and goods/passenger lifts installed in existing buildings where limitations enforced by certain building constraints mean that some requirements of EN 81-20:2020 cannot be met.

This document is intended to be read and applied in conjunction with EN 81-20:2020. It addresses the following constraints and gives requirements for alternative solutions:

existing perforate walls of the lift well;

reduction in available well are leading to reduced distance between car, counterweight or balancing weight;

counterweight or balancing weight in a separate existing well;

reduced building dimensions and clearances leading to:

reductions in available space for headroom and pit;

reduced car roof balustrade dimensions;

reduced height of sill apron;

reduced height of machine and/or pulley room;

reduced available area for access door/trap door;

reduction in available height of landing doors.

This document is not applicable to lifts installed before the date of its publication.
