MB Crusher increases your utility excavator’s potential
Utility excavators are built for digging—but with the right tools, they can do so much more. For contractors working in utilities and public works, jobsite efficiency, mobility, and cost control are key. Whether it’s trenching for cable installation, repairing sewer lines, or laying water mains, excavators are often underutilised once the digging is done.
MB Crusher changes that—transforming utility excavators into full-scale material processing units. With the addition of attachments, your excavator can crush, screen, and handle material on-site— which means eliminating delays, reducing haulage needs, and maximising productivity.
Utility Excavators: A Platform for Full Jobsite Control
Traditionally, utility excavators dig, then wait. Crews haul away spoil, bring in backfill, and sometimes call in other equipment to manage material. But what if the same excavator could crush the material it just excavated, screen it for reuse, and even move or load it?
That’s what MB Crusher attachments are designed to do, to allow utility contractors to:
- Crush excavated rock or debris into backfill material.
- Screen soil and debris for reuse or cleaning.
- Handle and process material, all with the same carrier machine.
Step-by-Step: One Excavator, Multiple Tasks
Let’s walk through a typical utility excavation project—equipped with MB Crusher tools.
Step 1: Dig the Trench
Using your standard utility excavator, you begin trenching to lay pipe or conduit. This is where the machine performs as usual—but the process is about to become far more efficient.
Step 2: Crush the Excavated Material with MB Crusher Bucket
Instead of piling up spoil to be hauled away, the operator attaches an MB Crusher bucket, such as the compact MB-C50 (for utility machines from 6,5 ton). These crusher buckets process on-site material—crushing rocks, broken pavement, or debris into usable secondary aggregate.
Result: You eliminate the need for transport and can reuse the crushed material as trench backfill or base.
Step 3: Sift through with MB-HDS Padding Bucket
Next, swap to the MB-HDS207 padding bucket—part of MB’s HDS range designed for 3 ton carriers. With interchangeable shafts, the MB-HDS207 is ideal for screening wet or dry material, breaking up soil clumps, and separating organics or lightweight debris.
Result: You prepare fine, consistent backfill or filter suitable material directly on-site, using a compact, versatile unit.
Step 4: Reuse and Refill
Crushed and screened material is placed back into the trench using the same excavator. No haulage. No waiting. And no need to purchase imported fill.
Optional: Shape and Reach with MB-R500 Drum Cutter + Rotating Tower
In confined urban areas or tricky corners, precision is key. Equip the MB-R500 drum cutter with its optional rotating tower accessory. This allows 360° tool rotation—ideal for shaping trenches, working against walls, or accessing tight angles—with minimal vibration, making it especially suited for roadworks and city infrastructure projects.
Result: Cleaner cuts, more control, and less disruption in sensitive urban environments.
The Ultimate Upgrade for Utility Excavators
MB Crusher attachments are engineered to be quick to install, easy to operate, and compatible with any brand of utility-class excavators. They’re especially valuable for:
- Urban jobsites with limited access or haul routes.
- Contractors aiming to reduce material handling and dependency on third-party services.
- Utility providers looking to speed up operations and cut environmental impact.
Instead of sitting idle between digging tasks, your excavator becomes a mobile processing centre—crushing, screening, refilling, and shaping, all with one operator.
Real-World Example: MB-G350 Rotating Grab Enables Precision in Heritage site
In Gorizia, Italy, during the restoration of the historic Giardino dei Viatori, contractor Andrea Luciani faced the challenge of reconstructing three stone staircases on a steep slope with limited manoeuvring space. Utilising the compact MB-G350 rotating grab his team efficiently repositioned the original stones without manual handling.
Advantages:
- Precise placement of irregular stones
- Access to confined and sloped areas
- Reduced physical strain on workers
- Preservation of historical materials
As Luciani noted, "Without the MB Crusher selector grab, reusing the original ancient stone would have been impossible."
Conclusion: Unlock the Power of Your Utility Excavator
Your excavator is already doing the digging—why not let it do the rest? With MB Crusher attachments, you gain full control of the jobsite from start to finish. No more delays. No more outsourcing. Just one machine doing it all.
