FEATURE SUPER SHOVEL IN THE NAME OF EFFICIENCY HAWAIIAN CEMENT SWITCHES GEARS WITH HEAVY IRON AT THE QUARRY FACE. By Mark S. Kuhar CHALLENGE: Replace two pieces of equipment at the quarry face with one. SOLUTION: An EX1200 shovel from Hitachi. TIP: With the shovel stationary and operating on a level surface, it was much easier on the operator. 28 ROCKproducts • JANUARY 2013 H awaiian Cement is a major sup‐ plier of aggregate, cement, and ready‐mix for the Aloha State. Its aggregate facility, which is known for being a model of efficiency, de‐ cided to take a hard look at its opera‐ tional efficiencies. It was time for a change, and Macy wanted to look at all of his options, in‐ cluding shovels, a machine that the company had never used before. His research took him to the mainland to watch these machines at work in oper‐ ations similar to his. It didn't take long for them to discover a better way to move a large volume of material. "We were using a loader and dozer to do the work," said Jason Macy, vice president of operations for the company. "The loader didn't have the breakout to handle the material, so we also had to use a dozer to push the ma‐ terial to the loader." One machine he evaluated was a Hi‐ tachi EX1200 – and he liked what he saw. He liked it even better when he heard what the operators had to say about its speed, power and depend‐ ability. "Everyone we talked to said the EX1200 exceeded their expecta‐ tions," Macy said. www.rockproducts.com
