kiesel gM Bh NNew Hitachi Large Wheel Loader for Extraction of Natural Stone Since July 2010 the Hitachi large wheel loader ZW550 is operating in block handling format in a South-German jura marble quarry with processing plant. Together with the system partner LOC-Matic, the front equipment was optimally adapted to the individual requirements of the quarry and the performance parameters of the Hitachi wheel loader. Equipped with hydraulic quick changing device, the ZW550 can flexibly be applied with raise sprocket for block extraction. Issue 04 | 2010 NEWS & REPORTS New Standards in Mining HITACHI’S NEW LARGE WHEEL LOADER IN ACTION Table 1: Overview of modeltypes Kiesel: Hitachi wheel loader ZW550 in block-handling design – in operation in the Jura marble quarry since July 2010. HITACHI WHEEL LOADERS AND HYDRAULIC DREDGERS ARE KNOWN FOR THEIR HIGH QUALITY, PERFORMANCE AND ROBUSTNESS, PARTICULARLY NEEDED IN HARD EXTRACTION OPERATIONS. THE FIRST HITACHI LARGE WHEEL LOADERS WERE INTRODUCED IN BAUMA 2010, RESULTING FROM THE ALLIANCE BETWEEN HITACHI CONSTRUCTION MACHINERY UND KAWASAKI HEAVY INDUSTRIES. AS ONE OF THE FIRST MACHINES DELIVERED TO GERMAN, A ZW550 CONVINCES IN EXTRACTION OPERATIONS. ZW330 ZW370 Often a short-term higher performance is needed during breakage of the blocks, and this performance is easily achieved by Hitachi with a pressure connection of the hydraulics. In block transport the large wheel loader convinces with highest loads. Moreover the ZW550 is equipped with an adjustable traction control, which automatically adjusts to the working conditions. The box frame, a low hinged lifting cylinder and two bucket cylinders make this wheel loader-model even more effective for application in natural stone extraction.
