Drilling and compacting

Breaker-mounted compactor

A hydraulic breaker whose point has been replaced by a wide flat metal foot bolted into the nose of the hammer, tamping the bottom of an urban trench excavation. Two workers in orange vests in the background.
The foot is bolted into the nose of the hammer:
it is the percussion that tamps.
Synthetic image.

A compaction plate fitted in the nose of the hammer, in place of the point.
The percussion of the breaker becomes the source of the tamping:
you compact with the tool you already have.

Other names for this tool: breaker tamping plate, hydraulic hammer tamper, adaptable compaction plate, compaction foot.

01 Use

What it is for

On the left, with the foot in place of the point, the hammer tamps the bottom of the excavation. On the right, for real compaction, the dedicated vibrating plate remains the right tool. Computer-generated image.

Left: with the foot in place of the point, the hammer tamps the bottom of the excavation.
Right: for real compaction, the dedicated vibrating plate remains the right tool.
What sets it apart:
it is no longer a breaker, and it is not yet a vibrating plate — it is a stopgap use.

The principle is an economy:
the hammer is already there, it is already connected, and its hydraulic line is already set.
You take off the point, you fit the foot, and the machine goes from demolition to tamping without changing tool or getting down to adjust anything.

It is a stopgap use, and it has to be said that way:
taking up the bottom of an excavation after demolition, tamping backfill around a structure, tamping a one-off repair.
On a site where compaction is the main work, it is not the right tool.

It is no longer a breaker, and it is not yet a vibrating plate. A hammer is designed to concentrate the energy on a point, a vibrating plate to spread it at a chosen frequency:
the adaptation borrows the rhythm of the hammer, which is not that of a compactor.
The output shows it, and the result can be measured. See the vibrating plate.

02 What we check with you

On which machine?

It fits on the breaker, in place of the tool.
The machine class is that of the breaker carrying it: we calculate it with you for your machine.

What the tool does

It compacts using the breaker's impact.
The plate dimensions, the compaction force and its weight: we calculate them with you for your machine.

What is needed on the hydraulic side

It needs no power source of its own: it uses the breaker's.

Your study sets the exact value for your machine.

Don't have these figures?
A photo of the machine is enough to start.

03 Your study

Have your machine checked.

Give us the exact make and model of your breaker, and a photograph of its nose.
Tell us also how much time a week you spend compacting:
it is that figure that says whether the adaptation is the right calculation.

What we need to answer you
  • Your machine Its exact make and model.
  • What is fitted What equips the machine today.
  • The work What the machine is used for.

Without these details, the study still begins: we will ask you for them.

Not to be confused
  • Vibrating plate and compaction wheel Principle — a plate designed to spread the energy, at a frequency chosen for compaction.
    Use — it is the tool for a site where compaction is the main work, at the bottom of an excavation or a trench.
  • Compaction wheel Principle — neither percussion nor vibration: all the force comes from the weight and the arm of the machine.
    Use — it moves quickly along a service route, with no auxiliary line, where impact noise is unwelcome.
04 Choice

What determines the choice

  • 01 — The breaker you own It is what decides, and it alone.
    The adaptation fits on a specific hammer nose:
    the exact model of the hammer is the first question, before the surface to be compacted.
  • 02 — The real frequency of use A few minutes a day, or several hours?
    Beyond a stopgap use, a dedicated plate or a wheel costs less in hammer wear.
  • 03 — The area of the foot It is sized on the hammer, not on the trench.
    A foot too large for the energy available strikes without compacting.
  • 04 — The wear passed on to the hammer Compacting loads the hammer differently from demolition.
    What you save on the tool, you sometimes pay in maintenance.
05 Check

What is checked before ordering

  • The exact designation of your breaker Make, model, and a photograph of the nose.
    Without that, no adaptation can be ordered.
  • The device that holds the tool in the nose It has to hold a foot, not a point:
    the forces do not go in the same direction.
  • The hydraulic setting of the hammer It was made for demolition.
    The question of whether it is still suitable is put to the hammer's supplier.
  • The site's compaction requirement If a rate is imposed, this solution is rarely the one to choose.
