GB/T 8419-2023 Earth-moving machinery - Laboratory evaluation of operator seat vibration 1 Scope 1.1 This document specifies, in accordance with ISO 10326-1:2016, a laboratory method for measuring and evaluating the effectiveness of the seat suspension in reducing the vertical whole-body vibration transmitted to the operator of earth-moving machines at frequencies between 1 Hz and 20 Hz. It also specifies acceptance criteria for application to seats on different machines. 1.2 This document is applicable to operator seats used on earth-moving machines as defined in ISO 6165. 1.3 This document defines the input spectral classes required for the following earth-moving machines. Each class defines a group of machines having similar vibration characteristics: ——rigid-frame dumpers >4500 kg operating mass; ——articulated-frame dumpers; ——scrapers without axle or frame suspension ) ; ——wheeled loaders >4500 kg operating mass; ——graders; ——wheeled dozers; ——soil compactors; ——backhoe loaders; ——crawler dumpers; ——crawler loaders; ——crawler-dozers ≤50000 kg operating mass ) ——compact dumpers ≤4 500 kg operating mass; ——wheeled compact loaders ≤4500 kg operating mass; ——skid-steer loaders, wheeled ≤4500 kg and tracked ≤6000 kg operating mass. 1.4 The following machines impart sufficiently low vertical vibration inputs at frequencies between 1 Hz and 20 Hz to the seat during operation that these seats do not require suspension for the attenuation of transmitted vibration: ——excavators, including walking excavators and cable excavators ); ——trenchers; ——landfill compactors; ——non-vibratory rollers, except soil compactors; ——vibratory rollers, except soil compactors;
