GB/T 28621-2023 Safety rules for the construction and installation of new lifts in existing building
Abstract
1.1 This document specifies the safety guidelines for new passenger elevators and freight elevators permanently installed in existing buildings, which cannot meet certain requirements of GB/T 7588.1—2020 due to building restrictions.
This document lists these restrictions and provides requirements for solutions:
a) Perforated elevator shaft walls;
b) Small shaft dimensions resulting in a reduced distance between the car and the counterweight (or balance weight);
c) Counterweight (or balance weight) located within a separate shaft;
d) Reduced building dimensions and spacing, leading to:
——Reduced space in the top floor and pit;
——Reduced dimensions of the car roof guardrail;
——Reduced height of the car skirting board;
——Reduced height of the machine room and/or pulley room;
——Reduced area of the maintenance door or hatch;
——Reduced height of the floor door.
