It is not mounted on the coupler:
it is suspended.
That is not a detail of fitting — it is what tips the operation into another set of rules.

01 Use

What it is for

**Left:** hanging from the hook, the skip carries the concrete right up to the formwork.
**Right:** the mixer lorry stops where its chute can no longer reach.
What sets it apart:
it carries the concrete to the formwork, where the truck mixer can neither back up nor swing out its chute.
Computer-generated image.

A truck mixer pours where it can back up and swing out its chute.
Past that limit — at the bottom of a plot, behind a house, below an embankment, in the middle of a field — either a pump is needed, or something that carries the concrete to the formwork.
The skip does that carrying.

It takes its fill at the truck mixer's chute or under the mixing bucket, the machine carries it, and the discharge is worked from above the formwork. With a mixer upstream, you make and pour on site:
no truck mixer, no pump, no delivery delay.

Strip footings, ground beams, pads, posts, chambers, low walls, fence anchorings, small isolated structures:
modest volumes, scattered, and rarely accessible.

A skip suspended from an excavator is a lifting operation — not earthmoving work. Permissible load at the real reach, safety-catch hook, slings in good order and inspected, packing under the machine, and nobody under the load. The conditions under which your machine is allowed to lift are read in its manual and on its load chart — we do not summarise them here, and nobody should do it in your place. What we say about lifting operations.

02 What we check with you

On which machine?

A concrete skip hangs from the machine's hook: this is lifting.
The machine class and its lifting capacity, at the front or to the side: we calculate them with you for your machine.

What the tool does

It carries concrete on the hook and empties mechanically.
Its volume, its maximum load when full and its empty weight: we calculate them with you for your machine.

What is needed on the hydraulic side

It needs no hydraulic connection.

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 your excavator model, the reach at which you have to pour and the volume per structure.
Above all, tell us whether your machine has an approved lifting hook:
without it, the question of the skip does not yet arise.

What we need to answer you

Your machine Its make and its tonnage.
The auxiliary circuit Its flow in l/min, its pressure in bar, single- or double-acting.
The coupler in place Its system and its class.
The work The use, and the material.

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

04 Choice

What determines the choice

01 — The usable volume, read as a load A skip is sold in litres, but it is chosen in kilos.
Fresh concrete is heavy:
the volume, multiplied by its density, very quickly gives a load that exceeds what a small machine can hold at full stretch. The right skip is the one your excavator lifts at the reach where you pour, not the largest in the catalogue.
02 — The method of discharge Bottom gate to fill a wide formwork quickly.
Chute to direct the stream.
Flexible sleeve to go down into a narrow or deep formwork without the concrete segregating as it falls.
These are three different jobs.
03 — Where the control is Most skips open with a lever, from the ground:
someone therefore stands beside the load, while the machine holds it. This is the point where two activities overlap, and it is settled beforehand, not during.
Some remote controls make it possible to stand back.
04 — The shape A conical skip stands on its own on the ground and fills easily under a chute.
A cube skip takes up less room and travels better.
At equal volume, these are two different footprints and two different stabilities on the ground.

05 Check

What is checked before ordering

What your machine is allowed to lift This is the first question and it has nothing to do with the skip:
it is read in the manual and on the excavator's load chart, at the reach at which you pour.
The hitching point Lifting hook approved, with a safety catch.
A welded ring, a shackle put through a bucket lug or a sling taken round the dipper arm are not lifting points.
The slings and their records They have a maximum working load and a periodic inspection.
They are part of the assembly being lifted, not consumables.
The ground under the machine An excavator lifting at maximum reach on ground that gives way is the classic scenario.
Packing and levelling are settled before the first load, not at the third.
Cleaning A skip that is not washed at the end of the pour loses its usable volume and its gate ends up no longer closing.
Plan for water on site.
