Chicago Pneumatic RX 30 and RX 38 hydraulic breakers have hybrid gas/oil technology.
Chicago Pneumatic RX 30 and RX 38 hydraulic breakers have hybrid gas/oil technology. Hydraulic pressure lifts the hammer for striking, then a combination of hydraulic power and nitrogen charge drives the hammer to strike. According to the manufacturer, the combination provides 15 to 20 percent more power than single-sourced energy.
The RX 30 has a service weight of 4,850 pounds, an impact rate of up to 620 bpm at 5,500 lb.-ft. It is specified for carriers with a capacity of 55,100 to 88,200 pounds. The RX 38 has an impact rate of 590 bpm at 6,500 lb.-ft. and a service weight of 5,740 pounds. It is specified for carriers with a capacity of 59,000 to 98,000 pounds.
The RX line has noise- and vibration-dampening. The PowerControl Plus feature enables the operator to adjust the breaker’s performance according to the application. Other features include a tie rod system that uses tie bolts, an insert thread system that ensures a long working life and allows tie bolts to be reused, as well as a central lubrication port for extended bushing life.
Essential Case-Mounted (EC) range of hydraulic breaker attachments has expanded with the addition of five Small Range breakers to the lineup.
The Montabert V1800 and V2500 Evolution hydraulic breakers feature an automatic two-speed variation system that adjusts their impact energy and striking rate to deliver high energy per blow on hard ground and high frequency on soft ground.
