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.

Rockland Manufacturing, based in Bedford, Pa., has introduced the Klac system — a mechanical quick coupler for mini-excavators from 2,200 to 22,000 lbs. (998 to 9,980 kg). 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. These systems can be time-consuming to use because they require the operator to leave the cab for unhitching and hitching. Often the operator also must leave the cab after hitching to adjust slack and/or alignment on the attachment after it is mounted. In addition, many mechanical coupler systems add length to the angle of the bucket, changing the working geometry of the entire machine and lowering its breakout force.

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.

While a hydraulic quick coupler is the most efficient coupler type in terms of operation, it is often expensive, with labor-intensive installation. The Klac system offers mini-excavator owners a mechanical coupler that is simple, inexpensive and efficient, according to the manufacturer.
