Forestry working means and ergonomic requirements

Sažetak

The paper describes chief instruments of forest production and their ergonomk: requirements. The level ot mechanization in the forestry production differs from high in logging and roadbuilding to a considerably lower one in silviculture, where nursery production stands out with the level of mechanization equalling that of agriculutre. Ergonomie requirements greatly depend on the attitude of a particular social enwironment towards work safety. Some ergonomie requirements lake the form of standards, recommendations or agreements. The chain saw is characterized not only by ergonomie-technical properties but also by mass, noise and vibration. Over the past three and a half decades, each of these parameters has come to conform to stricter and stricter requirements. Mass has been reduced to less than 8 kg, noise near the cutter's ear to about 100 dB(A), and the estimated acceleration transfer to the hand/arm system (WAS) below 12.5 m/s2 (frequently even below 10 m/s2).
