Coupling and adapting

Fully automatic coupler

Two hydraulic half-couplers face to face, ready to engage: the male with its tapered end on the left, the female on the right with its ring of locking balls and its knurled collar.
That is what sets the automatic apart from the rest:
the hydraulics connect without anyone getting out of the cab.
Synthetic image.

The hydraulic connection is made at the same time as the locking.
The driver changes a breaker for a bucket without getting down or connecting a hose.

Other names for this tool: automatic coupler, fully automatic quick coupler, coupler with integrated hydraulic connection.

01 Use

What it is for

On the left, coupling up also connects the tool's hydraulics, with no hose to connect. On the right, with a conventional coupler, the hoses still have to be connected by hand. Computer-generated image.

Left: coupling up also connects the tool's hydraulics, with no hose to connect.
Right: with a conventional coupler, the hoses still have to be connected by hand.
What sets it apart:
no hose to connect — what you do not connect by hand does not leak, and does not get forgotten.
Computer-generated image.

It is the only technology that does away with handling hoses.
Where a hydraulic coupler saves the time of locking, this one saves the time of connecting as well — and does away with the movement where you get dirty, where you force things, and where you sometimes forget to connect again.

It is justified where tools are changed several times a day:
demolition, sorting, a constrained urban site.
The calculation is made in driver's time, never in purchase price.

It is a fleet decision, not a tool decision. It assumes that every tool that is to be fitted carries the matching equipment.
One tool not equipped and the driver gets down again. See the five technologies.

02 Key technical data

On which machine?

The machine class depends on the system and the size: we calculate it with you for your machine.
It is itself the coupler.

What the tool does

It is used to couple and adapt tools, fully automatically.
Its weight: we calculate it with you for your machine.

What is needed on the hydraulic side

It works hydraulically, with a dedicated control.
It needs enough hydraulic lines, with sufficient flow and pressure.
The flow and pressure: we calculate them with you for your machine.

Your study sets the exact value for your machine.

03 Your study

Have your machine checked.

Tell us how many tools make up your fleet and how many times a day you change them.
It is that figure that decides, not the tonnage.

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 number of tools to convert The real cost is that of the whole fleet, not that of the coupler.
  • 02 — The number of changes a day Below a certain rate, the hydraulic coupler remains the right choice.
  • 03 — The lines available on the machine The system calls for more of them than a simple coupler:
    it is the point that most often rules a carrier out.
  • 04 — The safety gained Fewer operations on the ground around the machine, so less exposure.
    On some sites, it is the main argument.
05 Check

What is checked before ordering

  • The complete inventory of the tools to be equipped Sheet by sheet, without forgetting one:
    that is where the costing is decided.
  • The machine's hydraulic lines Number, flow and pressure available at the end of the dipper arm.
  • Training the driver The movement changes;
    the automatic system is not a dispensation from checking.
  • Converting the existing mounting plates It is rarely nil, and it can be costed.
