Dromone says its cast-steel, hydraulic quick coupler weighs about 30 percent less than excavator quick couplers with fabricated steel bodies. A range of sizes to fit everything from backhoes to large hydraulic excavators offer designs to minimize extension of the bucket-curl radius and preserve digging force. A hydraulic circuit locks the coupler from the cab and the locking mechanism is always visible from the cab allowing the operator to visually confirm that the coupler is fully engaged. A Dromone coupler sized for a 16-metric-ton excavator, weighs 360 pounds and carriers a manufacturer suggested retail price of $4,000.
