ISO 20474-5:2008 specifies safety requirements and protective measures for hydraulic excavators as defined in ISO 6165. It is intended for use with ISO 20474-1, which provides general safety requirements for earth-moving machine families, and ISO/TS 20474-14, which addresses mandatory national and regional provisions.
The standard covers significant hazards and foreseeable misuse during commissioning, operation, and maintenance. Topics include access, operator stations, protective guards, ROPS and TOPS, operator seats, controls, swing brakes, stability and safety devices, rated capacities for bucket, shovel, log-handling, and object-handling applications, parking brakes for compact crawler excavators, and specific requirements for walking excavators.
It also provides verification requirements, operator manual information, stability conditions, protective structure provisions, load safety considerations, retrieval and towing requirements, and illustrative figures for common excavator configurations.
Application Scope: Applicable to manufacturers, designers, engineers, safety professionals, inspectors, operators, and organizations responsible for the design, conformity assessment, operation, or maintenance of hydraulic excavators.
