| Caterpillar Forest Products upgrades innovative bunching saw  Caterpillar Forest Products has made enhancements to the Prentice SH-50 bunching saw to increase performance, durability and reliability and to respond to customer requests for design refinements. Introduced two years ago, the saw features the innovative Strait Grip bunching finger (patent pending) that tucks trees into the accumulating pocket, keeping the tops together and creating tight bunches. Ideal for first and second thinnings, this innovative bunching technology allows the operator to cut, bunch and control more wood before piling. Other saw designs don't keep the treetops together, forcing the operator to drop the load before reaching full capacity.Recent enhancements improve performance and lower operating costs. The discharge chute has been enlarged 130% to quickly exhaust chips and debris from the saw housing. Additional design changes to the saw housing shed debris from the top of the disc and safely direct it toward the ground to improve saw performance, eliminate plugging and greatly reduce wear. Hydraulic hoses have been upsized and rerouted to improve reliability. A new bulkhead holds the bunching finger hoses neatly in place and reduces wear. The bulkhead is removable allowing easy access to hoses when servicing is required. From front to back, all guards that protect hoses and the saw motor have been beefed up to prevent debris build-up and damage from high capacity bunching. Improvements include better bolt retention and reinforced guard supports. The Prentice SH-50 bunching saw is available for the Cat 553 and Cat 563 wheel feller bunchers. When installed on the larger carrier, the Cat 563, the full capacity of this attachment can maximize production in both thinning and clear cutting applications. The SH-50 can bunch 13-15 6-in. diameter trees or 25-27 4-in. diameter trees. write your comments about the article :: © 2009 Construction News :: home page |
