  • Rapid and secure changing
  • Connection of quick coupler and adapter via adjusting sheet on SW housing free from backlash
  • Sealed interlocking mechanics, long durability and low level of maintenance
  • Universal adapter system suitable for all excavator makes
  • Low loss of tear-out strength

Robust quick coupler:
The system is composed of two components: the quick coupler and the adapter for the attachment. The quick coupler has a robust, closed housing with two stable hooks, with which the attachment can be lifted, displaced and positioned before bolting.

Stable seating in the adapter:
The quick coupler has mechanically finished receptacle and placement surfaces for the adapter. The adapter consists of the receptacle shaft and the finished crossbar plate with exact dimensional accuracy and high quality finish. After bolting, both sides form a solid, stable connection.

Mechanically locked:
The quick coupler can be interlocked effortlessly and quickly with two crossbar bolts and mechanical dead-centre interlocking simply by using socket spanners.

Hydraulically locked:
A hydraulic cylinder with unblock-capable shut-off valve holds the crossbar bolts securely in position.
