Civil engineering and roads

Opening, laying, closing, giving the road back.
A services job is judged on what it leaves behind it — and the tooling counts for a lot in that.

This trade also covers: roads and utilities, drainage, housing-estate earthworks, laying pipes, urban development, trench works.

01 The trade

What this trade demands of the tooling

A roads job strings together very different movements in a single day:
cutting the asphalt, opening, clearing out, laying, backfilling, compacting, resetting the kerbs.
Each calls for a tool, and none of them lasts long.

Here the constraint is not the power:
it is the time the road is occupied.
Everything that lengthens the work — a tool change by hand, a job to be done again because the cut was untidy, a compaction to redo — is paid for in signing, in disruption and sometimes in penalties. It is the trade where the quick coupler pays for itself fastest.

A trench in a town centre is an occupied carriageway. Everything that lengthens the work is paid for elsewhere — in signing, in disruption, sometimes in penalties.

02 The tools

The tools that matter, in the order of the job

  • 01 — Cutting before opening The asphalt disc marks the line.
    Asphalt torn out with a bucket lifts at its edges, and the reinstatement comes back.
  • 02 — Opening Earthmoving bucket for the excavation, trencher for a narrow slot, directional drilling rig when opening is forbidden.
  • 03 — Profiling and cleaning out Ditching bucket, trapezoidal bucket for a V ditch, grading blade for the spreading.
  • 04 — Closing up The vibrating plate compacts the bottom of the trench where no ride-on roller goes down.
    It is that compaction that decides whether the carriageway will sink in two winters' time.
  • 05 — Resetting The kerb grab holds the kerb in place of arms.
    It is an occupational health argument before it is an argument of output.

Three to five tools on the same job, several times a week. It is that figure that should decide the coupler, not the price of the coupler. See the hitching technologies.

03 Check

What is checked before fitting out

  • The number of hydraulic functions available After feeding the coupler.
    It is what is left that determines the possible tools. See the 7 criteria.
  • Consistency of coupler across the whole fleet If you have several machines, one and the same coupler family lets the tools be shared.
    It is the easiest saving, and the most often forgotten.
  • What the client imposes Some reinstatements require a clean cut, controlled compaction, a particle size.
    Those requirements designate the tool before you do.
  • The existing services Locating them beforehand is not a matter of choosing a tool, but it entirely governs the method and sometimes the type of machine.

Have your fleet checked.

Give us your machines, their couplers, and the type of jobs you string together.
In this trade, the right answer rarely concerns a single tool:
it concerns the consistency of the whole.
