Mechanical quick-coupler for mini-excavators

Rockland Manufacturing has introduced the Klac system, which the company claims is the world’s first mechanical quick coupler for mini-excavators from 2,200 to 22,000 pounds (1 to 10 metric tons). The Klac system reduces the amount of time spent unhitching and hitching attachments because of its simple design with fewer parts that eliminates the need to adjust, service or grease the coupler. The Klac system is adaptable to any mini-excavator bucket, and its rugged cast steel construction ensures long wear life. Owners of mini-excavators historically have dealt with mechanical coupler systems that require safety pins, keys, nuts, cams, seals, thread mechanisms and/or wedges, among other parts. With the Klac system, the operator unlocks the coupler by pulling a lever. The Klac system then can lock a new attachment into place automatically, without the need for a safety pin. The Klac system features double safety levels, using two springs versus one. Because it follows the original machine’s digging geometry, there is no loss of breakout force.
