General safety requirements for forestry machinery

1 Scope

This standard stipulates the safety requirements for self-propelled forestry machinery and assembling forestry machinery according to the requirements of operations. This standard includes forestry machinery in General normal hazards, dangerous situations and events that the manufacturer can reasonably foresee during normal use or misuse, such as logging specified in ISO 6814 Wood machine, stacker, branching machine, consolidator, wood loader, skidder, combined working machine, combined feller and shredder, and the above machine The multifunctional combined working machine combined together. This standard does not involve hazards specific to individual machines, such as those related to specific accessories. Therefore, the use of this standard alone cannot be sufficient to cover This standard covers all serious hazards of most machines. This standard does not cover those related to breakage and slinging of the saw chain above the guide plate, cargo handling, remote control operation, work light requirements, and road safety harm. This standard does not involve vibration measurement test devices and working cycles, nor does it involve noise measurement inspection methods. This standard does not apply to the hazards associated with professional maintenance personnel maintaining and repairing machines. See Appendix A for a list of serious hazards listed in this standard. This standard does not apply to machines produced before their implementation.
