By trade

Railways

The tool is the simple part of the problem.
What decides a job near a track is settled before it — and not with an attachment supplier.

This trade also covers: track maintenance and renewal, track handling, surroundings and access roads, clearing the railway land, drainage of the formation.

01 The trade

What this trade demands of the tooling

This page is shorter than the others, and that is deliberate.
On a track, the question of the tool comes after a series of questions we do not control:
access to the railway land, the protection regime of the site, the certification of the people, the acceptance of the machine and how it travels.
We shall not deal with them here.

What we can say is narrower, and safer:
what a tool does, what sets it apart from another, what is checked before ordering it.
The rest is given to you by the operator of the line, in a form that has nothing to do with a catalogue. Better a short and accurate page than a full one.

The tool is the last question, not the first. Access to the railway land, the protection regime of the site, the certification of the people and the acceptance of the machine itself are settled beforehand, with the operator of the line.
We shall quote here no rule that we do not master: those conditions are given to you by the operator, not by an attachment supplier.

Track renewal site: a road-rail excavator set on the rails by its rail axles, bucket in the ballast, while a gang in orange vests handles sleepers along the track.
The machine travels on the track and works from the track:
that is what governs the coupler, the envelope and the safety rules.

02 The tools

The tools that matter, in the order of the job

  • 01 — Handling the track The rail grab holds a piece that is long, heavy and smooth, and whose behaviour in the air is never that of a block.
    The multi-sleeper lifting beam takes a batch and lays it down in line:
    the gain is not in the piece, it is in the cycle.
  • 02 — Lifting, and knowing what you are lifting Lifting eyes and lifting hook are the points provided for slinging;
    a bucket tooth is not.
    The load cell informs, the limiter prevents :
    those two words do not designate the same equipment, and confusing them is the most frequent mistake on this subject.
  • 03 — Picking up and separating the aggregate The skeleton bucket lets the fines fall during loading;
    the screening bucket makes the same separation with a quite different output.
    What you are allowed to put back, on the other hand, is not decided here:
    that comes from the operator.
  • 04 — Keeping the vegetation of the surroundings in check The saw trimmer cuts a clean plane in a single pass, where a mulcher would tear.
    Of theflail mower, it is the head alone that fits on an excavator:
    you gain the ditch and the steep bank, you lose the length of work.
    The weed-control brush tears out without any product, so with no re-entry period.
  • 05 — Restoring the drainage The ditching bucket takes up the ditch again and profiles the shoulder.
    A formation that no longer drains degrades from below, where nothing shows as long as nothing has moved.
  • 06 — Seeing, when you work at night Theboom LED lighting follows the tool, which a cab floodlight does not;
    the on-board camera reduces the blind spot that the turret sweeps at every rotation.
    A camera replaces neither the organisation of the site nor the person on the ground.

These jobs are often done at night, or during a traffic interruption granted in advance. That changes the tool little and the rest a great deal:
the lighting, the visibility, the number of manoeuvres, and the margin you have if a tool breaks down.
The standby equipment is provided for beforehand, because the working window, for its part, is not extended.

03 Check

What is checked before fitting out

  • The conditions set by the operator Access, protection of the site, certifications, acceptance of the machine.
    They govern everything else, including the choice of machine.
  • The monitoring of the lifting accessories Who checks them, how often, with what traceability.
    That is not discovered on the morning of the job.
  • The working position of the machine From the track, the shoulder or the access road:
    the reach is not the same, and neither is the load chart.
  • The lighting and vision installation It is adjusted at night, once fitted, on the machine that will do the work. See the boom lighting.
