Ropot pri spravilu lesa z žičnim žerjavom Urus III

Lipoglavšek, Marjan (author)

V članku so prikazani rezultati meritev ropota na dveh deloviščih pri spravilu lesa z 2 žičnima žerjavoma URUS III na kamionu TAM. Ropot med prostim tekom ne presega NR 70, med polno vožnjo pa presega NR 90. Obremenitve strojnika z ropotom (Lekv) so znašale v vsem delovnem času med 82 in 90 dB(A), najmanj pri tesno zaprti, največ pri slabo zaprti kabini. Večinoma presegajo dopustne meje 85 dB(A), vendar če jih primerjamo z mejami za ropot s prekinitvami, so bili strojniki izpostavljeni sluhu škodljivemu ropotu samo pri slabo zaprti kabini, pri odprti pa ne.

Abstract

The article presents the results of noise measurements in two working places carried out during two days at wood skidding by means of two URUS III cable crane on a TAM trnek. The noise during idle motion did not exceed NR 70 but during load drive it exceeded NR 90. The noise loads of an operator (Lekv) were between 82 and 90 dB(A) during the entire working time, the lowest with a cabin tightly closed and the highest with a cabin insufficiently closed. They mostly exceeded the still permitted limits of 85 dB(A) yet if compared with the limits permitted far the noise with interruptions, operators were exposed to noise harmful to hearing only with an insufficiently closed cabin and not with an open one.
