ISO 2867 pdf download Earth-moving machinery — Access systems
This International Standard specifies criteria for systems that provide access to the operator station and toroutine maintenance points on earth-moving machinery as defined in ISO 6165.lt is applicable to the accesssystems (e.g. enclosure openings,platforms， guardrails， handrails and handholds，stairways and steps,ladders) on such machines parked in accordance with the manufacturer’s instructions. lts criteria are based onthe 5th to 95th percentile operator dimensions as defined in ISO 3411. lt deals with the following significanthazards， hazardous situations and events: slip, trip and fall of persons,unhealthy postures and excessiveeffort.
The general principles set out in this International Standard can be used for the selection of fixed andlorportable access systems for repairs, assembly, disassembly and longer interval maintenance.
