Scope

This part of GB/T 20448 specifies a uniform and reproducible evaluation method for the force and deformation of self-propelled forestry machinery Rollover Protective Structure (ROPS) under static load, and specifies the test prototype under this load. performance requirements. It can be applied to forestry machines as defined in ISO 6814, such as: forwarders, skidders, feller bunchers, combine harvesters, combine feller harvesters and log loaders, but not to those with a cab on a rotary table Boom lifting appliances (see ISO 8082-2 for a discussion of this part).
