Direct pin-on mounting
the pin, the bush, and the play that appears between the two.
Synthetic image.
The tool mounts directly on the dipper arm pins.
No intermediate coupler:
cheaper, more rigid, and slower to change.
Other names for this tool: direct mounting, pin-on mounting, pin mounting, rigid mounting.

What it is for
Right: changing tools means removing the pins, with the machine out of action.
What sets it apart:
nothing is inserted, so the reach and the breakout force are at their maximum — and the change is paid for in time.
Computer-generated image.
It is the original mounting on every excavator, and it remains the right choice when the machine carries only one tool, or when tools are almost never changed.
Nothing is inserted:
the tool is as close as possible to the dipper arm, the reach is at its maximum and so is the breakout force.
Its drawback is known:
changing tools means knocking out two pins, with two people, with time and a drift.
It is that cost that tips the balance towards the quick coupler as soon as there is a second tool.
There is no designation to read: it is the machine's dimensions that carry weight — pin diameter, pin centres, width between plates.
They are read to the millimetre, and they are specific to each model.
A wrong dimension means buying a tool that does not fit.
On which machine?
Direct pin mounting suits all machine classes.
It uses no coupler: it is made to the pin dimensions of your machine.
What the tool does
It links the tool directly to the machine's pins.
Its weight: we calculate it 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.
Have your machine checked.
Give us the make, the model and the year of your excavator.
If you can read off the diameter, the pin centres and the width yourself, say so:
we will confirm your dimensions.
- 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.

the tool is as close as possible to the dipper arm. That is the maximum reach and the maximum force — at the price of knocking out the pins at every change.

What determines the choice
-
01 — The number of tools in the fleet
Only one:
direct mounting can be defended.
Two or more:
the quick coupler soon pays for itself. -
02 — The reach sought
Nothing is inserted, so nothing moves away from the dipper arm.
On a small machine, the difference is felt. - 03 — The budget It is the cheapest arrangement, by far.
- 04 — The site time available Knocking pins out in the middle of the day does not cost the same on every site.
What is checked before ordering
- The diameter of the pins Measured with a vernier, not estimated.
- The pin centres The distance between the two pins, to the millimetre.
- The width between plates It governs whether the dipper arm goes through.
- The condition of the bores An ovalised bore is repaired before fitting, not after.
