GB/T 7588.1-2020 Safety rules for the construction and installation of lifts—Part 1：Passenger and goods passenger lifts English
1 Scope
1.1 This part of GB/T 7588 specifies the safety rules for permanently installed new passenger or goods passenger lifts, with traction, positive and hydraulic drive, serving defined landing levels, having a car designed for the transportation of persons or persons and goods, suspended by ropes, chains or jacks and moving between guide rails inclined not more than 15° to the vertical.
1.2 In addition to the requirements of this part, supplementary requirements need to be considered in special cases (use of lifts by persons with disabilities, in case of fire, potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous goods, etc.).
1.3 This part does not cover:
a) lifts with:
1) drive systems other than those stated in 1.1;
2) rated speed less than or equal to 0.15 m/s;
b) hydraulic lifts:
1) with a rated speed exceeding 1 m/s;
2) where the setting of the pressure relief valve (5.9.3.5.3) exceeds 50 MPa;
c) new passenger or goods passenger lifts in existing buildings1) where, in some circumstances due to limitations enforced by building constraints, some requirements of this part cannot be met and the requirements of GB/T 28621 need to be considered;
d) lifting appliances, such as paternosters, mine lifts, theatrical lifts, appliances with automatic caging, skips, lifts and hoists for building and public works sites, ships' hoists, platforms for exploration or drilling at sea, construction and maintenance appliances or lifts in wind turbines;
e) important modifications to a lift installed before this part is brought into application;
f) safety during operations of transport, erection, repairs, and dismantling of lifts.
However, this part may usefully be taken as a basis.
Noise and vibrations are not dealt with in this part as they are not found at levels which could be considered harmful with regard to the safe use and maintenance of the lift (see also 0.4.2).
1.4 This part is not applicable to passenger and goods passenger lifts, which are installed before the date of its publication.
