Electric Earthmoving Machinery Terminology

1 Scope

GB/T 44254-2024 is the Chinese vocabulary of electric earth-moving machinery. Construction plant is electrifying quickly in China, and the vocabulary has had to be built from nothing: the terms come partly from automotive electrification, partly from industrial trucks and partly from the existing earth-moving machinery standards, and they were being used inconsistently in specifications, safety documents and service manuals at exactly the moment when precision mattered most, because these are high voltage machines maintained by mechanics whose training was diesel. The standard defines the terms across the field: the machine types and their electric configurations, battery electric, cable electric and hybrid, the energy storage system and its components, the electric drive and its control, the charging equipment and interfaces, the high voltage system, its isolation, protection and safety terms, and the performance and rating terms by which such a machine is specified. For anyone reading Chinese electric construction machinery documentation, this is the key to the vocabulary. It took effect on 24 July 2024.

This document defines the terms and definitions for electric earth-moving machinery, key systems and components, charging and battery replacement facilities, safety and performance. This document is applicable to the scientific research, design, manufacturing, writing of relevant technical documents and technical exchanges of electric earth-moving machinery.
