GB/T 21937-2008 Earth-moving machinery—Crawler and wheel tractor dozer blades—Volumetric ratings

Scope

This standard specifies the calculation method for the capacity of bulldozer blades, with the aim of providing a unified comparison method for the capacity of bulldozer blades in commercial documents for bulldozers (as defined in GB/T 8498). This standard is not intended for predicting the productivity of bulldozers under actual working conditions or the productivity of bulldozers that may be observed under various specific working conditions. To determine the productivity of bulldozers in these situations, other parameters such as the efficiency of bulldozer blades, the power of bulldozers, traction force, soil characteristics, terrain, the operator's technical level, and work cycles need to be considered.
