The RCB line of construction breakers is available in monoblock or tie-rod configurations.
Eight monoblock models fit excavators ranging from 1,600 to 28,000 pounds. Polyurethane jackets are designed to reduce impact vibrations transferred to the machine and help reduce noise. The diaphragm accumulators do not require recharging. Five tie-rod models fit excavators ranging from 28,000 to 130,000 pounds. Their internal components can be accessed and repaired without dismantling the tie-rod assembly, Rotobec says. They also feature a manual stroke adjuster and pistons mounted on three bushings for longer life.
