GB/T 27545-2024 in English

1. Background and significance of the standard

GB/T 27545-2024 "Horizontal circulation type mechanical parking equipment" is the latest standard jointly issued by the State Administration for Market Regulation and the National Administration of Standardization, replacing the original GB/T 27545-2011. This standard comprehensively revises the terminology, technical parameters, manufacturing requirements, installation specifications and test methods for horizontal circulation type mechanical parking equipment, aiming to improve the safety, reliability and intelligence level of the equipment.

3. Interpretation of the main contents of the standard

3.1 Scope and terminology definition

This standard applies to the horizontal circulation type mechanical parking equipment defined in GB/T 26476, and clarifies that the equipment types include circular circulation, rectangular circulation and multi-row and multi-column circulation. The new term "horizontal circulation type mechanical parking equipment" and its definition are added to ensure the uniformity and standardization of industry terms.

3.2 Types and basic parameters

The equipment types are divided into three types: circular, rectangular and multi-row and multi-column circulation, and each type is equipped with a schematic diagram (Figure 1). The basic parameters include the size, mass and maximum entry (exit) time of a single car, and the maximum storage capacity should not exceed 100 parking spaces.

3.3 Technical requirements

Technical requirements cover environmental conditions, design and configuration, overall performance and safety protection. For example:

• Ambient temperature range: -5℃ to 40℃, altitude not exceeding 1000m.
• Metal structure materials: The mechanical properties of the main load-bearing structural parts shall not be lower than Q235 steel or No. 20 steel.
• Welding quality requirements: There shall be no obvious defects in the appearance of the weld, and the acceptance level of radiographic inspection shall not be lower than the Level 2 standard of GB/T 37910.1-2019.

3.4 Installation and test methods

Installation requirements include firm connection of metal structures, track deviation control and buffer installation error. The test method adds static load test and dynamic load test to ensure that the equipment operates normally under rated load and dynamic conditions.
