McLaughlin Mfg.

The model McL-48/54 is capable of cased boring sizes ranging from 16 inches to 60 inches in diameter. A quick-connect split-design feature enables machine components to individually be moved in and out of the trench, reducing required lifting capacity and making it easier to position the machine. This powerful boring machine develops 950,000 pounds forward thrust at 5,000 psi, and 170,000 foot/pounds auger torque in first gear. The power train includes an air-cooled 6-cylinder turbo-charged diesel engine that develops 162 horsepower at 2,500 rpm, electromagnetic clutch, and 5-speed transmission with reverse and planetary reduction final drive to the 4-inch hex chuck. The low-profile (only 32 l/2-inch to the bore centerline) and electric Operator Presence Control reduces the risk of roll over, an important feature on high-torque machines. Other features include extended triple-cylinder stroke and auto hydraulic dog plate that increases boring efficiency and speed. (800) 435-9340,
