OQL 310
OilQuick automatic quick coupler system, type OQL310 is suitable for mid-sized wheel loaders in the weight class 6-20 t.
Why OQL?
Dirt guards
Robust dirt guards with a reliable opening mechanism protects the quick couplings when using mechanical attachments without OilQuick-function.
Hardened hook axels
Improves the couplers longivity and minimizes play.
Locking arms
One piece locking arms that provides a more stable and reliable construction.
Replacable steel bushings
In order to keep the tight tolerances after wear and tear between the locking plungers of the locking arms and the quick coupler, replacable steel bushings have been introduced.
Electrical coupling
Compact design.
Screw-on couplings
Hydraulic couplings with integrated guidings makes replacement and service faster.
