Engineered Steel — Built for Real Load
The frame is constructed from a high-strength, abrasion-resistant steel typically used in extreme wear applications.
• Yield strength approximately 3–4× higher than standard structural steel (Grade 50)
• High resistance to deformation under load
• Designed to handle repeated stress without fatigue
This isn’t typical structural steel—it’s material chosen specifically for how this tool is used.
DESIGNED WEAR POINTS — CONTROLLED, NOT RANDOM
Stonekraken is built with intentional wear surfaces.
Critical components like pins and spacers are designed to:
• Absorb wear in predictable areas
• Protect the structural frame
• Be serviceable over time
Instead of hidden failure points, wear is managed and controlled.
TOOL STEEL — WHERE PERFORMANCE HAPPENS
The splitting teeth are made from high-carbon tool steel and heat treated through their full depth to approximately 58 Rockwell hardness.
• Exceptional edge retention
• Resistance to chipping and deformation
• Consistent performance over time
This is full-depth hardness—not surface treatment.
PRECISION FIT — CONSISTENCY UNDER LOAD
Key components are machined to ensure:
• Proper alignment during operation
• Smooth, repeatable movement
• Even force distribution throughout the tool
This reduces binding, minimizes uneven wear, and ensures consistent performance from the first use to long-term operation.
HARDWARE — SMALL PARTS, BIG ROLE
There are relatively few fasteners in the tool—and that’s intentional.
Each bolt, nut, and interface point was selected for:
• Strength and reliability
• Proper load distribution
• Long-term durability
Nothing is there by accident.
Finishes — Functional, Not Cosmetic
Different components receive finishes based on how they function:
• Black oxide on high-strength alloy components for corrosion resistance without affecting tolerances
• Protective coating on structural elements for durability in harsh environments
These choices are made for performance—not appearance.
PROVEN HYDRAULIC SYSTEM — BUILT FOR THE LONG RUN
Stonekraken is built around a proven hydraulic system from BVA Hydraulics, known for producing high-quality cylinders and pumps used across demanding industrial applications.
Key features of this HYDRAULIC system include:
-
Advanced internal sealing for long service life
-
A robust return spring for consistent retraction
-
Reliable performance under reapeted load cycles
-
The system is rated for up to 70,000 cycles under proper operating conditions.
-
Stonekraken is designed to operate within that working range—reducing unnecessary stress on seals and internal components, and helping preserve long-term performance.
at the end of the day - It’s not just about how hard a tool can work — it’s about how long it can keep working hard.
A FEW WORDS ABOUT HYDRAULICS:
Most Splitters Push Their Limits. We Don’t. A lot of hydraulic stone splitters on the market look the same—and in many ways, they are. They have the same size cylinder. Same 10-ton rating. Same 10,000 PSI systems.
But here’s the difference:
Most of them rely on running at or near max pressure to achieve full splitting power.
And while that’s within the rating, it comes at a cost—higher stress on seals, fittings, and components over time. That’s why many manufacturers and industry guidelines treat ~80% of max capacity as a smarter range for long-term reliability.
Stonekraken Takes a Different Approach:
We don’t chase performance by pushing the system to the edge.
-
We limit the system to 8,000 PSI
-
Then use mechanical leverage in the frame to multiply force where it matters
The Result:
-
Up to 24,800 lbs at the teeth
-
More real splitting force than a typical 10-ton splitter
-
Less stress on the hydraulic system
Bottom Line:
-
Other splitters depend on max pressure to perform.
-
Stonekraken is engineered to outperform—without wearing itself out.
