Anotace textu normy ČSN EN 81-21 ED.2   (274003)

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.
