Brokk 500 demolition robot features 40% power increase



Rockland Manufacturing Company., an accessory maker based in Bedford, Pa., launched its Wear Pin technology, designed to allow operators to determine the life of a part by examining it. When a moldboard, blade, liner, or wear plate wears down to a specific point, contrasting wear pins appear, signaling the need for future maintenance or replacement.

The amount of wear over a certain period of time at a certain location can also be determined with technology. Different materials can also be easily evaluated and tested in specific applications.

“We created this technology for two reasons,” says Bill Pratt of Rockland Manufacturing. “First, to avoid unplanned downtime due to equipment failure by using a visual wear indicator, and second, to eliminate the need for multiple labor-intensive ultrasonic inspections.”

When the steel structure of a bucket or blade wears out, cracks appear which may not be noticeable on visual inspection. If the cracks are not properly repaired in a timely manner, they will continue to develop. Designed to eliminate the need for continual ultrasonic inspections evaluating the extent of cracks, wear pins installed directly into the bucket shell, blade moldboard or other liner component during manufacture become visible when the steel has worn to a point at which operators must plan for maintenance or prepare for replacement.

“When buckets or blades wear down and cracks start to occur, repairs can become expensive, especially given the potential loss of production,” says Pratt. “Unscheduled downtime is the enemy of the profitability of any fleet of equipment and Rockland’s Wear Pin technology is a direct response to tackling the unexpected. “

Wear Pin technology is currently available for excavator buckets, loader buckets, bulldozer blades and coatings used in heavy equipment industry including mining, quarrying, aggregate, waste handling, demolition and logging. Wear Pin technology is also available for truck bodies, dump bodies, chutes and other tools.
