Title Assessment of heavy earth-moving machinery noise vis-Ó-vis routine maintenance
Bibliographic information Mar.-Apr. 2006, Vol.54, No2, p.64-78. Illus. 25 ref.
Abstract This study investigated the noise generation characteristics of heavy earth moving machinery (HEMM) as influenced by periodic maintenance. Detailed noise measurements were carried out in a large open pit coal mine in India. The effect of maintenance on noise production was assessed for ten dumpers and three dozers by measuring sound pressure levels after the machines had been subjected to maintenance at the end of 300 hours, 500 hours, 750 hours and 1000 hours of use. Measurements were also carried out to assess the effect on noise levels of maintaining specific HEMM components after 1000 hours of use. Major sound level reductions were observed after each periodical maintenance. The data also identified the major noise generating systems in HEMM as being air systems, exhaust systems, cooling systems and fuel systems.
