BRUCE Piling Equipment · Equipment selection
Choose the hammer around your pile, ground and carrier
Vibratory hammer selection brings together five decisions: ground suitability, pile and clamp fit, mounting arrangement, hydraulic compatibility, and the project’s acceptance requirements.
Use this guide to prepare a model inquiry for your U.S. project. If you are comparing installation methods first, start with how a vibro hammer works.
Review the ground and installation method
Begin with the ground investigation and the full profile to the intended pile toe. Share the borehole or CPT records, groundwater information and any known obstructions with the equipment supplier.
Vibratory driving is generally most effective in granular soils. Stiff or hard clay and difficult layers can limit progress; a larger hammer alone does not establish drivability. Ask the project engineer and supplier to review those layers and identify any need for additional analysis, trial installation or a different installation method.
For bearing piles, agree how capacity will be verified. Reaching the specified depth is one part of the installation record. The FHWA driven pile foundation manual, Volume II (PDF) discusses vibratory equipment and construction control; apply the requirements specified for your project.
Define the pile and clamp arrangement
Send a pile drawing with dimensions and weight for the section actually being driven. A sheet pile pair, single H-pile and steel casing each need their own configuration review.
- Pile geometry: profile, section size or diameter, wall thickness, length, weight and any joints or splices.
- Installation task: driving, extraction or both; temporary or permanent work; intended embedment and quantity.
- Clamp fit: available gripping surfaces, jaw arrangement, clearance and the supplier’s confirmed compatibility.
- Handling: single or paired piles, stack position, available headroom, pile support and positioning method.
Request a drawing of the proposed hammer-and-clamp assembly. Confirm the complete assembly weight and dimensions before checking the carrier and handling plan.
Choose the mounting arrangement
Compare the available carrier, reach and site access alongside the pile requirements. Include space for handling piles, hoses and any separate power pack.
Read the specifications as a system
Compare current data sheets for the proposed configurations. Ask what operating conditions and attached components each published figure assumes.
On smaller screens, scroll the table sideways to read all columns.
| Parameter | What it describes | Ask the supplier |
|---|---|---|
| Eccentric moment | The rotating eccentric mass-and-radius quantity that contributes to vibration. | How does the proposed moment suit the hammer, clamp and pile combination? |
| Frequency | The vibration rate, commonly stated in vpm or Hz. | What operating range is available for this configuration and power source? |
| Centrifugal force | The oscillating force associated with eccentric moment and frequency. | At what frequency is the quoted force produced? What separate lifting and extraction limits apply? |
| Amplitude | The vibration displacement; the attached vibrating mass affects it. | Is the value peak-to-peak, and which clamp and pile mass are included? |
| Hydraulic supply | Flow, pressure, power and circuit requirements for the attachment. | What supply, return-line, cooling and filtration requirements must the carrier or power pack meet? |
For background on the mechanical parameters, see the PDCA sheet pile hammer guide (PDF, pages 7–8).
Read “maximum” carefully. The published BRUCE SGV-40 specification lists maximum oil flow as 235 L/min (approximately 62 U.S. gpm). That number alone is not a minimum flow requirement or confirmation of excavator compatibility. Request the operating requirements for the exact package.
Plan field verification before mobilization
Agree what information is needed to confirm the proposed setup on site. Where a trial is specified, define the records and review process in advance.
- Installation records: pile identification, depth, time, equipment settings and observed ground or installation issues.
- Acceptance: the project’s alignment, embedment and testing requirements, with the responsible reviewer identified.
- Site effects: required noise and vibration assessment, monitoring locations and response procedures.
Evaluate vibration at the site level. A higher frequency rating by itself does not establish that nearby structures will be protected. Caltrans vibration guidance is a reference for assessment; the applicable project criteria and monitoring plan still need to be established.
For daily planning and operating checks, continue with the vibro hammer efficiency and safety checklist.
Vibratory hammer selection FAQ
What size vibratory hammer do I need for sheet piles?
Provide the sheet pile section, single or paired arrangement, length, weight, target embedment and ground report. The supplier also needs your carrier and hydraulic information. Pile length alone is insufficient for a model recommendation.
Can I choose an excavator attachment by excavator tonnage alone?
Use the exact carrier configuration and attachment requirements. Tonnage is an initial screening detail; hydraulic supply, attachment weight, geometry, working reach and approved mounting also need review.
What should a model recommendation include?
Ask for the proposed hammer, clamp, mounting and power source, the project inputs used, assumptions, application limits and any additional review needed. Then request a quotation for that defined package using the BRUCE buying and quote guide.
Your next step
Send BRUCE a complete project brief
Include your U.S. project location, pile drawing and weight, ground report, intended depth, driving or extraction task, carrier details and required delivery date. State any missing information so the recommendation can identify what still needs confirmation.
Request: a proposed configuration, current technical data, assumptions, application limits and the information needed to complete selection.
