Abstract

"DISPOSIçãO DE CAçAMBA". A invenção refere-se a uma disposição de caçamba que inclui uma caçamba, uma porta de caçamba, e um mecanismo de fecho. A porta de caçamba é pivotavelmente ligada com relação à caçamba, e tem uma posição fechada na qual a porta de caçamba fecha o fundo aberto. O mecanismo de fecho tem uma posição travada e uma posição destravada, e é fixado com relação à caçamba e ligado com a porta de caçamba. Na posição travada, o mecanismo de fecho mantém a porta de caçamba na posição fechada. Na posição destravada, o mecanismo de fecho permite que a porta de caçamba oscile em afastamento à posição fechada.
