Shark Fin was originally designed and patented for use in a high-speed application with Automatic Lumber Grading Systems, accommodating up to 225 boards per minute. We started to develop Shark Fin in 1993 because we were unable to find a non-mechanical board turner that would work at these high speeds. With Automatic Lumber Graders quickly becoming a reality, Shark Fin will help to prepare mills for this transition while increasing productivity and preventing grader injuries. NO TOUCH Grading System
Shark Fin is designed to have singulated boards put onto lugs on the grading table and automatically turn the boards over in front of each grader. This is a “no touch” system except where the grader is required to physically put a crayon mark on each board. Shark Fin is a totally non-mechanical board turning system not driven by gears, chains, belts or anything else. This system is inertia driven where the board helps to turn itself as it is pushed along the line by the lugs.
Shark Fin can be used on grading tables with 1 to 7 graders. It can be easily coordinated into separate colours for easy identification so that each grader is always aware of which boards they are responsible for grading. For example, the grader using the red board turner, will only grade the boards presented to them in the red lugs and should mark with a red crayon. This allows for the grader to easily identify their next board and helps to make training new graders easier.
Installation of your Shark Fin System can be completely finished within two days and even faster if your present lug loader or board dealer is on the infeed of your grading table and you are presently dealing into lugs. This installation can be done by the mill.
Double Pulp Safe
All Shark Fin components are manufactured from high-impact REDCO Double Pulp Safe polyurethane to ensure your products are protected from marking, dents, grease, and oil. A piece of metal is embedded in the middle of the lugs and stars to ensure that they are picked up by your metal detectors in the event of any breakage. In the event that they are not picked up by the metal detector, these parts are heavier than water so they will sink to the bottom of your pond and not go through your mulcher.
