Stockpile bucket This bucket is used for loading stockpile products, such as crushed rock and construction materials.
This bucket is used for excavating and loading blasted rock on rock crushing job sites, or for
Excavating bucket excavating natural ground. It has a flat-blade, straight cutting edge, and provides superior rigidity
and wear resistance.
Loose/light material This bucket is used for loading materials with comparatively light specific gravity. It is based on the
bucket general purpose bucket, with a lengthened cutting edge and width to give increased capacity.
These teeth are suitable for loading or excavation of piles of earth or sand, blasted
Teeth rock, and jobs in the field that involve digging into the side of slopes. The special
(bolt-on type) heat treated, tensile strength steel alloy used in their production assures that they
will wear and have a long service life.
These teeth tips which are attached to an adapter that is welded or bolted to the
Teeth bucket edge. This means that an interchangeable part, the tooth tip, absorbs most of
(tip type) the wear and protects the actual bucket edge. They give excellent performance when
used to handle blasted rock, piles of earth and similarly heavy duty tasks.
