Ripping is becoming more popular-and not only because of drilling and blasting regulations. The popularity is due in part because of advanced hydraulic systems, which have allowed ripping to actually become a production process. Track-type Tractors with rear-mounted rippers are the traditional tool. However, large Cat Hydraulic Excavators feature enough hydraulic strength to pull rippers through rock that would have been thought impossible to penetrate only a few years ago. Some rippers are available in both pin-in and Quick Coupler settings. The rippers are built for heavy work, with reinforced, one-piece shanks. Add an increased hydraulic flow and you get production power. Cat Hammers are ready for even tougher materials and a heavy, destructive blow and can easily handle the reduction of quarry oversize. The hammers also feature vibration dampening to reduce stress transmission to the stick and boom. And ripping of overburden has become even easier with advances in work tools and ground engaging tools.Caterpillar Inc: www.cat.com
