Die Annotation des Normtextes 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
