Catalog excerpts

BTI’s VZ Series of Hydraulic Breakers offer outstanding power to weight ratio, and exceptional efficiency with the energy regeneration system. Features & Benefits Long / Short Stroke Selection Operator controlled hydraulic pilot valve or mechanical selector valve optimize impact strength and blow speed for maximum performance in varying rock conditions. Energy Regeneration System A unique control system harnesses the breaker recoil energy improving breaker efficiency, increasing blow rates up to 15% in hard rock conditions. Anti-Blank Fire Selection All VZ Series breakers can be configured for blank-fire or anti-blank-fire operation. Underwater Application Remote air porting at the top of the breaker allows for underwater operation with the addition of a compressed air supply. Remote Greasing A remote grease port for tool bushings at the top of the breaker provides trouble free connection to automatic greasing systems, supplied separately. Hose Routing The VZ85 and VZ120 models are equipped with heavy duty side mounted hose swivels for improved hose protection in heavy raking applications. All VZ Series breakers are equipped with rear porting for optimum hose protection in trenching applications. Narrow Front Head The narrow front head allows for trenching in confined spaces. The narrow profile allows optimum visibility and access when working in tight quarters. Exceptional Structural Integrity Boxed section housing provides excellent strength while remaining lightweight. The suspended boxed housing design reduces noise and vibration to the carrier. Compressed polyurethane isolators suspend the breaker body on all sides, absorbing and protecting the carrier boom from recoil energy. This feature provides the unique benefit of preventing tie rod strain during blank firing and raking. Front head support allows minimal movement, leaving cylinder and gas head free without stressing the tie rods.
