Earth-moving machinery — Safety — Part 6: Requirements for dumpers

This International Standard specifies safety requirements and protective measures for wheeled and crawler dumpers, including compact dumpers.

ISO 20474-6:2008 specifies safety requirements and protective measures for wheeled and crawler dumpers, including compact dumpers and compact dumpers with a standing operator. It addresses significant hazards associated with commissioning, operation, maintenance, and foreseeable misuse. The standard covers dump bodies, body-lowering and warning devices, body support devices, retarders, articulated frame locks, rollover and falling-object protective structures, operator stations, steering systems, seat belts, verification, and information for use. It is intended to be used with ISO 20474-1 for general requirements and ISO/TS 20474-14 for mandatory national and regional provisions. It does not apply to road-truck-mounted dumpers or machines manufactured before its publication date.

Application Scope: Earth-moving machinery manufacturers, designers, safety engineers, inspectors, regulators, and operators working with wheeled, crawler, articulated, rigid-frame, swing, and compact dumpers.
