Product & applications
About the pile breaker
A hydraulically operated attachment for removing concrete pile heads. Circular modular and square-pile arrangements position crushing rods around the pile; select the layout for pile shape, dimensions and reinforcement.
Features & benefits
Modular circular arrangement
Circular systems combine modules around the pile. Module count changes the diameter range, total weight and carrier requirement.
Separate square-pile layout
Square-pile models have their own working range and cylinder arrangement; they must not be selected from the circular-pile module table.
Typical applications
- Foundation pile-head removalRemove surplus concrete above the designed pile cut-off level using the matching pile configuration.
- Bridge and infrastructure foundationsMatch the breaker arrangement to the pile section, concrete conditions and reinforcement that must be retained.
- Circular or square pile processingUse the corresponding layout and work in the permitted crushing increments rather than treating one size as suitable for every pile.
Pile breaker models and module configurations
Choose the pile shape and module configuration first. The circular-pile configuration table and square-pile table have different carrier and total-weight requirements. Listed production rates depend on pile dimensions, reinforcement, concrete strength and site conditions.

Installation requirements
Confirm the attachment fits your excavator
Before ordering, send the machine identification and the connection, power and working information relevant to this product.
- D1 / D2
- Both pin diameters
- C
- Pin centre distance
- W
- Clear mounting width
Pile and reinforcement details
Provide pile shape, diameter or side dimensions, concrete strength, cut-off level and reinforcement layout.
Module configuration and lifting
Compare the selected module count, complete assembly weight, lifting connection and actual excavator lifting chart.
Hydraulic circuit
Confirm system supply, pressure, total flow and manifold connection; a per-cylinder flow figure is not the complete system requirement.
Working clearance
Check access around the pile, chain or mounting clearance and the specified crushing height for each operation.
Product questions
Pile breaker questions
Is a pile breaker the same as a vibratory pile driver?
No. A pile breaker removes pile-head concrete. A vibratory pile driver installs or extracts suitable piles by vibration.
Can circular and square piles use the same specification table?
No. Select the pile shape and the corresponding configuration table. Circular module counts and square-pile model limits are listed separately.
Why does the required excavator capacity change with the number of modules?
Adding modules changes the working diameter and complete assembly weight. Use the row for the intended module count and verify the excavator’s actual lifting capacity.
Does the per-cylinder flow equal total hydraulic demand?
No. Review the complete cylinder and manifold arrangement. Confirm total system flow with the hydraulic configuration rather than treating one cylinder’s figure as the whole attachment demand.
Does pile-breaking output vary with site conditions?
Yes. Pile dimensions, concrete strength, reinforcement and site access affect output. Assess these conditions before estimating pile-breaking output.
