Lehnhoff system
the hook that takes the pin, the locks and their position indicator.
The image shows the principle common to all standards, not one standard in particular.
Illustration based on an existing product.
One of the systems met with regularly, alongside the S and CW types.
It is dealt with exactly like the others:
through the mounting plate.
Other names for this tool: Lehnhoff coupler, Lehnhoff quick coupler.

What it is for
Right: a mounting plate of another standard does not fit the coupler.
What sets it apart:
the designation marked on the coupler is the only piece of information that carries weight.
Computer-generated image.
A carrier equipped in this standard poses no particular problem:
the tool is ordered with the matching mounting plate, and it fits.
That is the principle that holds for all standards, common or less common.
What counts is not the name of the system but the exact designation marked on the coupler.
It alone allows the right mounting plate to be ordered first time.
We do not publish the table of sizes for this system: we have not confirmed it with the maker.
It is read off your coupler, and checked in the study.
An approximate figure would be worse than an empty box.
On which machine?
It fits a machine already equipped with a Lehnhoff coupler, with mechanical or hydraulic locking.
It follows the Lehnhoff standard, from size MS01 to MS08 and beyond.
The machine class depends on the coupler size: we calculate it with you for your machine.
What the tool does
It is used to connect and adapt tools to the Lehnhoff standard.
Its weight: we calculate it with you for your machine.
What is needed on the hydraulic side
Depending on the version, it is mechanical or hydraulic.
For the hydraulic version, the flow and pressure: we calculate them with you for your machine.

What determines the choice
-
01 — The designation marked on the coupler
It is the only piece of information that carries weight.
It is written MS followed by two figures, from MS01 to MS08 and beyond.
The SW notation is also found.
MS01 and SW01 are often given as equivalent:
to be confirmed on the manufacturer's dimension sheet. - 02 — The fleet already equipped It imposes the standard of the next tool.
- 03 — The availability of mounting plates It governs the lead time, not the feasibility.
-
04 — The locking method
Mechanical or hydraulic:
it is a question distinct from that of the standard.
What is checked before ordering
- The exact designation, photographed A legible photograph of the end of the dipper arm is worth more than a transcription.
- The model and tonnage of the machine To check consistency.
- The tools already in the fleet Their standard governs.
-
The acceptable lead time
A less common mounting plate is made to order;
that is planned for.
