EVS-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.
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.
