Abstract

EL MAZO TIENE POR OBJETO REDUCIR LA CONTAMINACION ACUSTICA PRODUCIDA POR LAS VIBRACIONES GENERADAS POR EL TRABAJO DE LA HERRAMIENTA (5). ESTO SE CONSIGUE VERTIENDO EN CALIENTE UNA SUSTANCIA DE POLIURETANO (13) ENTRE PAREDES COAXIALES (10, 11) DE LA CAJA (7). LA SUSTANCIA TENSA LAS PAREDES Y REDUCE ASI LAS VIBRACIONES EMITIDAS POR LA CAJA. EL MAZO SE UTILIZA EN MAQUINAS DE DEMOLICION DE ROCAS Y EDIFICIOS.
