HOW DOES THAT WORK?The breaker in the vibratory pick assembly is sealed inside the body eliminating the contaminantproblem found with the hydraulic breakers. By eliminating the contaminant problem, the secondhydraulic circuit is no longer required, therefore reducing the number of replaceable components andinventory requirements. Troubleshooting of the hydraulics is therefore easier. Other added benefitsare high productivity with the breaker inset in the body, plus over scaling is almost eliminated withthe profile design of the working tooth.Swing area and reach arecritical to achieving optimalefficiency – these abilitieswill eliminate the necessity tocontinually move the machine.Not all manufacturers offer this option. The best solutionto minimize damage to the hydraulic system is to have aseparate hydraulic circuit for the breaker with a gear pump.This will prevent contamination of the complete hydraulicsystem, reducing down time, and keeping maintenance costsat a minimum. The gearpump is a workhorsethat can withstandcontaminants for aperiod of time before itshuts down and requiresmaintenance.• A vibratory pickassembly with arotary actuator iswithout a doubt themost effective, efficientscaling tool available.The design combinesthe action of a pry-bar,pick, and hydraulicbreaker. Basically it is designed with a small hydraulicbreaker mounted inside of a mechanical pick body; anextremely narrow design with a raised tooth. This designCombining the action of a pry-bar, pick and hydraulic breaker with a rotary actuator is the mostefficient scaling tool available, providing excellent operator visibility and dexterity.provides excellent operator visibility and dexterity during allscaling modes eliminating the guess work on where the toolis as compared to a conventional breaker or hammer-feedsystem. For the operator, there’s the option of prying as amechanical pick or activating/firing the breaker to clear anyhard to remove areas. Theprying tooth is a replaceableoff-the-shelf product thatcomes in different widths,the advantage being awider tooth tends to be moreeffective in softer rock likelimestone, nickel ore, orgold ore and a narrow toothis more effective in hardermaterial such as granite orlead/zinc operations.A dedicated mechanizedscaler is purpose built forscaling large work areas thatcan be dangerous for theoperator. The technological advances seen in the last 5 to 10years proves the design side is improving with a focus towardoperator safety, not just efficiency. ■Wantmore?For more information, contact Breaker Technology Director of International Sales Robert McArthur atbmcarthur@rockbreaker.com, call 519.599.2015, or Director of US Sales Tom Witt at twitt@rockbreaker.com,call 951.369.8281, or visit www.rockbreaker.com.16 volume 3, number 1 | Today’s aggregate & mining solutions
