Manually operated multicouplings

Automatically operated
multicouplings

These couplings are used in case of fully-automatic
operation. Coupling movement is done mechanically,
pneumatically and hydraulically. Multicouplings in plate
mounting can be equipped with different media
elements according to requirements.

It is distinguished between:

• multicouplings in push-pull technique （see chart）

• multicouplings in pull-in technique

• multicouplings in push-technique with side entry

• special docking systems

TOOL-MASTER

Due to its modular design, the WALTHER quick tool
changing system 91489 is specially constructed to
meet individual customer requirements. It offers
application possibilities for automotive production and
other sectors and may be equipped with different
electrical or fluid transmission elements, depending
on the intended purpose.

• Static load capacity of up to 60.000 N
• low weight and und extremely flat design
• locking device remains play-free and self-locking in
the event of a pressure drop

Parking Stations

A gravity tool parking station is available for parking
tools quickly and safely in robot work stations.
The tool parking station is designed to the same
modular principle as the tool changer and can be
compiled with various individual components.
