Introduction

Due to the unique high-altitude environment in my country, construction machinery must meet these special environmental conditions and improve the adaptability and protection ability of the plateau: Necessary and very important: GB/T 20969 aims to establish the plateau suitable for internal combustion power machinery and construction machinery under special environmental conditions The requirements consist of five parts: --- Part 1: Plateau requirements for internal combustion powered machinery; --- Part 2: Plateau requirements for construction machinery; --- Part 3: Specifications for selection and acceptance of plateau construction machinery; --- Part 4: Guidelines for testing in plateau natural environment - Internal combustion power machinery; --- Part 5: Guidelines for testing the plateau natural environment for construction machinery: The purpose of this document is to enhance the adaptability of construction machinery in the plateau environment, and improve the performance of construction machinery in the special plateau environment: The work efficiency and reliability level, standardize the production, matching and use code of conduct: This document sets plateau environmental conditions on the basis of standard environmental conditions, and specifies the corresponding technical requirements for plateau construction machinery: The determination of the parameters of the plateau environmental conditions is based on the geographical distribution characteristics of the key construction projects in the west: Plateau machinery with special environmental conditions Part 2: Plateau requirements for construction machinery

1 Scope

This document specifies the environmental conditions, requirements, test methods and standards for construction machinery used in plateau areas with an altitude of:2000m~5000m: registration, packaging, transportation and storage, etc: This document applies to plateau construction machinery powered by internal combustion engines: Other special machinery with internal combustion engine as supporting power can be used for reference: Electric-driven construction machinery can be used for reference:
