Magnum Force Track Mounted Flail

Magnum Force 6300  Track Mounted Flail

The CBI Magnum Force Track Mounted Flail is engineered to be the industry’s most rugged and productive delimber/debarker. The development of this flail was dictated by the market and is based on the needs of logging contractors and particularly those operating in the Southern Hemisphere who work with Eucalyptus and other species with “stringy” bark. This debarker is an ideal complement to our 2-pocket and 4-pocket chippers used for the production of boiler fuel, traditional pulverized fuel and feed stock for pellet fuel manufacturing. With this design, material is fed into and out of the flail chamber by pivoting top feed roll assemblies with position sensing cylinders to ensure a controlled feed. Top Feed Rolls are driven by Poclain High Torque Wheel Motors.

CBI’s three-flail design provides optimum contact with wood to deliver maximum debarking action. It consists of two 50” swing diameter (1.27 m) top flail drums X 48” wide (1.21 m) with 11-link chains and one 40” swing diameter (1 m) bottom flail drum with 8-link chains. The top flail positions are determined by the top feed roll cylinder positioning sensors and the flail RPMs are automatically adjusted based on log diameters. Flail drums are driven by Rexroth hydrostatic pumps and direct coupled motors with variable speed from 0-700 RPMs.

The bottom feed rolls are driven by direct-coupled Char-Lynn Motors through a Brevini Gearbox. The inside of the flail chamber has replaceable wear liners for easy maintenance and overall longevity of this machine. Residue is discharged from the flail chamber by a large hydraulically-actuated push ram that utilizes a 5 1/2” bore, 90-inch stroke cylinder. The Magnum Force Flail Debarker also features a closed-loop hydraulic system with a 95-gallon (361 L) reservoir. The B-5 undercarriage features two-speed, heavy-duty drive motors and Bonfiglioli Planetary Gear Drives. Also, a folding maintenance platform on the non-drive side allows for easy maintenance. The 765 HP Caterpillar C-18 electronic diesel engine (not pictured in downloadable brochure) is equipped with a heavy-duty radiator and a hydraulically-actuated, reversing Flexxaire fan. Finally, the Magnum Force Flail Debarker weighs approximately 73,000 lbs. (33,121 kg) with a 250-Gallon (950 L) fuel tank. It is completely controlled by radio remote.
