NNew Hitachi Large Wheel Loader <strong>for</strong><br />
Extraction of Natural Stone<br />
Since July 2010 the Hitachi large wheel loader ZW550<br />
is operating in block h<strong>and</strong>ling <strong>for</strong>mat in a South-German<br />
jura marble quarry with processing plant. Together with<br />
the system partner LOC-Matic, the front equipment was<br />
optimally adapted to the individual requirements of the<br />
quarry <strong>and</strong> the per<strong>for</strong>mance parameters of the Hitachi<br />
wheel loader. Equipped with hydraulic quick changing<br />
device, the ZW550 can flexibly be applied with raise<br />
sprocket <strong>for</strong> block extraction.<br />

Hitachi wheel loader ZW550 in block-h<strong>and</strong>ling design –<br />
in operation in the Jura marble quarry since July 2010.<br />
HITACHI WHEEL LOADERS AND HYDRAULIC DREDGERS ARE KNOWN FOR THEIR<br />
HIGH QUALITY, PERFORMANCE AND ROBUSTNESS, PARTICULARLY NEEDED IN<br />
HARD EXTRACTION OPERATIONS. THE FIRST HITACHI LARGE WHEEL LOADERS<br />
WERE INTRODUCED IN BAUMA 2010, RESULTING FROM THE ALLIANCE BETWEEN<br />
HITACHI CONSTRUCTION MACHINERY UND KAWASAKI HEAVY INDUSTRIES. AS<br />
ONE OF THE FIRST MACHINES DELIVERED TO GERMAN, A ZW550 CONVINCES IN<br />
EXTRACTION OPERATIONS.<br />
ZW330 ZW370<br />
Often a short-term higher per<strong>for</strong>mance is needed<br />
during breakage of the blocks, <strong>and</strong> this per<strong>for</strong>mance is<br />
easily achieved by Hitachi with a pressure connection of<br />
the hydraulics. In block transport the large wheel loader<br />
convinces with highest loads. Moreover the ZW550 is<br />
equipped with an adjustable traction control, which<br />
automatically adjusts to the working conditions. The box<br />
frame, a low hinged lifting cylinder <strong>and</strong> two bucket cylinders<br />
make this wheel loader-model even more effective <strong>for</strong><br />
application in natural stone extraction.<br />
