CROSS CUT SLASHERDEBARKER INFEEDCONVEYOR/DEBARKERWhen strength really mattersSplitSprocketChallenge – Debarker Infeed conveyorStart/stop operation is required by the operator. This places demanding and varying loads on the drive chain.LambdaChainSolutionDrive chain: HT chain provides up to 30% greaterultimate tensile strength over standard roller chain.Mill chainSprockets: Forward/backward operation can resultin keyway backlash. The use of Powerlock sprocketseliminates the need for a keyway.Typical size range for this applicationRS80HT to RS160HT single and multi strand.WD(H)104, 110, 120. WH124(XHD) with C cradleattachment.Challenge – DebarkerFor ring debarkers there is shock load from crooked logs. Also high speed operation limits the effectiveness of lubricationdue to centrifugal force. Knife jam-up can require forward / backward operation. For drum debarkers, general operationoverload and/or high impact.ChallengeSolutionTypical size range for this applicationSolutionDrive chain: Lambda chain offersmaintenance-free operation.Mill chainSprockets: Remote access and the need for quickchangeout can be solved by split design sprockets.Remote access.Typical size range for this applicationRSD100Lambda to RSD140LambdaWR124(XHD), WR132(XHD)Drive chain: SpeedMaster designed for speeds greater than 400feet per minute. Special material, surface treatment and conn link.HT chain for higher tensile strength to resist shock load.Drag chainSprockets: Forward/backward operation can resultin keyway backlash. The use of Powerlock sprockets eliminatesthe need for a keyway.For ring debarker RS80SM or HT to RS160SM or HT single andmulti strand. For drum debarker Super 120 to Super 160-3.WD(RS)480(XHD), also sizes 104, 110, 120 and 132.With or without wing attachments.94 95
