To address specific short comings in the OEM design, all shoes across our Hitachi range have been significantly modified internally. Our Heavy Duty range provides greater roller path strength, increased case hardened depth and resistance to rock puncture of the bottom plate, significantly increasing service life. Our retainer bolts are also specifically designed to reduce pin float as well.
We also manufacture and supply drive tumblers to suit 5600 / 5500, 3600 and 2500/2600 machines.
