Supply by Therese Dunphy, Editor-in-Chief tdunphy@randallreilly.com ITʼS HAMMER TIME Whether at the face or breaking a blockage, hammers and breakers keep production moving. Durable and reliable Cat E Series Hammers offer a rugged design for extended durability and solid reliability, and features such as automatic shut-off, silencing, and vibration buffering make them easy on the operator. The hammers are designed to be field serviceable with common hand tools. The H180Es is the largest in the line and is designed for large excavators. The symmetrical housing allows it to rotate 180 degrees to compensate for wear, which effectively extends its life. The lower portion incorporates rock edges that add protection to the housing and enable quick positioning of boulders. Caterpillar | www.cat.com Handheld breakers Chicago Pneumatic Construction Equipment rolled out two new handheld breakers, the CP 1260 and the CP 1290. They include ergonomically designed handles to reduce operator fatigue; a streamlined, flatter profile to improve operator visibility; and new durable polyurethane front head springs that reduce wear and extend the life of the breaker and its internal components. Many components are compatible with previous generations of pneumatic breakers. The 1260 weighs 63 pounds and delivers 1,300 blows per minute. The 1290 weighs 81 pounds and is 28-inches long. It delivers 1,100 pounds per minute. Chicago Pneumatic | www.cp.com Long life and increased production Tramac has pioneered the TR Series excavator type systems. These units, with 350-degree turntable rotation, arched main boom section, and tapered dipperstick, are said to offer extended life and increased production not available with lighter duty units. The line is available with units featuring a reach up to 65 feet and can carry a 10,000-pound hammer. The manufacturer's standard control system is fully proportional electro-hydraulic joystick activated. The main control valve includes manual override handles for troubleshooting and emergency operation.
