1 Scope

GB/T 25694-2021 is the Chinese national standard on earth-moving machinery - skid-steer loaders, in the field of materials handling equipment. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 31 December 2021 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2022. Classification: ICS 53.100, CCS P97. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of skid steer loaders: This document applies to the tire or crawler skid steer loader (hereinafter referred to as the skid steer) as defined in GB/T 8498:
