Quick Coupler System D-Lock for Excavator

HYDRAULIC LOCKING SYSTEM

The hydraulic quick coupler enables an efficient and safe mounting of the attachments without manual work at the coupler itself. Different pin distances can be picked up.

ROBUST IRON CAST HOUSING
The excavator specific suspension is welded onto the robust iron cast body. Afterwards all contact surfaces are mechanically machined.
Load hook or lifting eye are optionally available.

SAFE LOCKING MECHANISM

Hydraulic locking and unlocking via double-acting hydraulic cylinder that moves a sliding jaw. Because of the long stroke of the cylinder, different pin distances can be locked in a safe and force-locked way.

DDITIONAL LOCKING AT FRONT PIN

The front pin is automatically locked by the moving cylinder. If the cylinder fails for any reason, the locking paws click into the slots on either side of the sliding jaw. Multi-slots cater for wide pin center range.

HYDRAULIC LOCKING SYSTEM

A hydraulic valve bank with special hyraulic valves at the quick coupler and the respective attachment enables an efficient and safe assembly of the attachments without manual work at the coupler itself.
The excavator turns into a multifunctional tool carrier.

FLEXIBLE BEARING

All parts are unified to guarantee a simple service.
The valve block on the attachment side is flexibly mounted, providing for an arched coupling.

SAFE LOCKING MECHANISM

The valve banks at coupler and attachment side are locked by a special locking system that absorbs the resulting expansion forces between the valves without transferring them to the quick coupler.

DIRT PROTECTION

The hydraulic valves and the valve block at the attachmet side are protected from dirt and damage by a cover plate. The very solid hydaulic vales can be coupled under pressure, no depressurization needed.
