Head extension for surface treatment operations

Abstract

Head extension for surface treatment operations including housing with first operative end and second operative end, both ends being open. Head extension incorporates cam assembly and holder assembly within housing. Cam assembly comprises motor, shaft, and plurality of cams configured to facilitate linear reciprocating movement. Holder assembly includes plurality of support plates and support loops configured to hold hoses used in surface treatment operations. Hoses extend through housing and interact with cams to achieve linear reciprocating movement. Head extension is designed for mounting on portable lifting equipment, such as portable crane or aerial work platform, thus allowing human operator to perform surface treatments at elevated or hard-to-reach locations while remaining on ground. Head extension is adaptable for use with various types of surface treatment media, including abrasives, water jets, and chemical sprays, providing versatility and enhancing operational efficiency and safety.
