Frequently Asked Questions

The Ultra Duty Rock Bucket is built for continuous use in rock excavation, quarry loading, and high-impact digging where the ground is extremely abrasive.
It's suitable for hard rock, granite, high-silica aggregate, and heavily compacted materials that cause severe wear on lighter-duty buckets.
Each bucket is supplied with replaceable teeth, lip shrouds, sidebar protectors, heel shrouds, chocky bars, wear buttons, and full internal and base wear protection.
Designed for 15 to 52t construction-class excavators from Caterpillar, Komatsu, Hitachi, Volvo, Liebherr, Hyundai, Develon, JCB, and Case.
Yes. Enstruc offers multiple bucket configurations for rock density, material size, and impact severity. Buckets can be customised with a selection of GET systems and wear packages to match site needs.
For lighter rock or mixed aggregates, our Extreme Duty Bucket offers excellent durability with less weight. For compacted soil and coarse materials, see the Severe Duty Bucket.
