Bucket with an opening bottom
in a trench, under an obstacle, in formwork.
Synthetic image.
It empties from below.
The bucket no longer needs to turn over to release its contents:
it lays them where they are needed, and only as much as is needed.
Other names for this tool: clamshell-bottom bucket, bottom-opening bucket, discharge bucket, moving-bottom bucket.

What it is for
Right: the conventional bucket tips over and drops everything at once, in a heap.
What sets it apart:
it gives the driver back the choice of the moment, the rate and the place, without changing the position of the arm.
Computer-generated image.
On a classic bucket, emptying means curling and reversing:
the material goes out in a heap, and it goes out all at once.
An opening bottom gives the driver back the choice of the moment, the rate and the place, without changing the position of the arm.
It serves for backfilling a trench in layers, for feeding formwork or a hopper, for depositing beyond an obstacle you do not want to cross with the machine.
Where the precision of the deposit counts more than the speed of emptying, it pays for itself.
What opens ends up jamming. A moving bottom lives in the material:
the pins, the guides and the ram take everything the bucket carries.
It is a tool that needs regular maintenance, and that point weighs more in the decision than the function itself.
On which machine?
A bucket with an opening bottom fits all excavator classes.
It attaches to all couplers, via a mounting plate.
What the tool does
It is used for digging and ditching.
The volume, the cutting width and the weight: we calculate them with you for your machine.
What is needed on the hydraulic side
It needs a double-acting hydraulic circuit.
The flow and the max. pressure at the circuit: we calculate them with you for your machine.
Your study sets the exact value for your machine.

Tell us what you are tipping, where, and at what height.
If the word “metering” comes up in your answer, this tool deserves to be studied.
- 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.

What determines the choice
-
01 — What you are tipping
Dry aggregate runs, damp soil arches over:
not everything can be metered. -
02 — The control
All-or-nothing opening, or progressive:
metering exists only with the second. - 03 — The hydraulic line available It decides before everything else.
- 04 — How exposed the mechanism is The more abrasive the product, the more the joint becomes the weak point of the tool.
What is checked before ordering
-
The material and its condition
Dry, damp, sticky:
that is what says whether the opening will really be of use. - The tipping height aimed at It governs the sizing as much as the volume does.
- The double-acting line and its control Presence, flow available at the end of the dipper arm, control in the cab.
- The maintenance plan Greasing points, wear parts, and access to change them.
