k) Added the dimensions of shaft depth, shaft width, entrance width, car width and car depth when the counterweight of a general-purpose elevator is placed on its side requirements (see Figure 7):

This document is modified to adopt ISO 8100-30:2019 "Elevators for the carriage of people and goods - Part 30: Elevators of categories I, II, III, and VI":

The technical differences between this document and ISO 8100-30:2019 and their reasons are as follows:

--- In 3:1:6, the definition of elevator was changed to meet the actual situation;

--- In 3:1:8, the definition of the well was changed to conform to the actual situation;

--- In 4:2, 320kg, 400kg, 600kg, 750kg, 825kg, 900kg, 1050kg, 1150kg are added, which are optional the rated load capacity is suitable for the national conditions of our country;

--- In 4:3, 0:5m/s is added as an optional rated speed to suit my country's national conditions;

--- In 5:1:2, delete the requirement of "see Figure 10~Figure 13 for specific market demand" to suit my country's national conditions;

--- In Table 1, the vertical allowable deviation of the shaft size has been changed to suit my country's national conditions;

--- In 5:2:1:2:2, the requirements for the allowable deviation K value of the hoistway are added, and Note 1 and Note 2 are deleted to suit my country national conditions;

--- In 5:3:2, the requirements for the waiting hall have been changed to suit my country's national conditions;

--- In Table 2, some of the rated load capacity and rated speed and the corresponding size requirements have been added, and the rated speed has been changed 2:5m/s rated load capacity 1000/1050/1150/1275kg top floor height, to suit my country's national conditions;

--- Changed the titles of Figure 10, Figure 11, Figure 12 and Figure 13, and deleted the dimensional drawing of the counterweight lateral position in Figure 11 to suit my country's national conditions:

The following editorial changes have been made to this document:

--- Deleted the note in Chapter 1 of ISO 8100-30:2019;

--- Deleted the example of 3:2:4 in ISO 8100-30:2019;

--- In 3:3:12, add Note 2;

--- In 4:1, the expression of the priority number system was modified to be consistent with GB/T 321-2005;

---In 5:1:1, Note 3 of Figure 5, Note 3 of Figure 6 and Note 3 of Figure 7, change "graphic symbols of ISO 7000-0100" to graphic symbols Number" ";

--- In 5:4:3:2:3, the calculation formula for the minimum width of the machine room is corrected;

--- In Figure 5, note 4 has been changed, and the description that the width of the hoistway is increased by 100mm in the case of machine room is added;

--- In Figure 7, add Note 2;

Introduction

0.1 The design parameters of elevators caused by elevator types and intended uses are relatively complex, and the range of design parameters for each elevator type is different:

Are not the same: In order to provide guidance in the preliminary planning stage of the building, make full use of the space, standardize the parameters of the elevator, and facilitate the elevator related parties to choose the elevator According to the different types of elevators, my country has established the main parameters of the elevator and the parameters of the car, hoistway, and machine room to support the elevator safety standards:

National standard system of types and dimensions: GB/T 7025 "Elevator Main Parameters and Types and Dimensions of Cars, Shafts, and Machine Rooms" is my country's elevator standard the basic standard of the quasi-system consists of three parts:

--- Part 1: Class I, II, III, VI elevators: The purpose is to specify the necessary dimensions required for passenger lifts:

--- Part 2: Class IV elevators: The purpose is to specify the necessary dimensions required for freight elevators:

--- Part 3: Class V elevators: The purpose is to specify the necessary dimensions required for a lift:

0.2 This document reflects the needs of the market, including:

---Special needs of users, including those with physical disabilities, requirements for convenience and mobility;

--- Appropriate use of stretchers, beds and paramedical equipment in hospitals and nursing homes;

--- Frequently used elevators with a rated speed of 2:5m/s~6:0m/s usually run in high-rise buildings;

--- Elevators whose rated speed does not exceed 2:5m/s determined based on the priority number system;

--- Where feasible, reduce the size of the shaft to improve the utilization of building space:

1 Scope

This document specifies the dimensions required for the installation of elevators of categories I, II, III and VI:

The dimensions given in this document reflect the requirements for the installation of elevators and their equipment:

This document applies to all lifts installed in new buildings with a single car or a through-entrance and with a drive system irrelevant: This document also applies to elevators installed in existing buildings:

This document does not apply to lifts whose rated speed exceeds 6:0m/s:
