Safety rules for the construction and installation of lifts - Lifts for the transport of persons and goods - Part 21: New passenger and goods passenger lifts in existing building

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
