JoeScan: Carriage Headrig


			3-D Scanning for Carriage Headrigs


	For carriage headrig applications, we recommend using one of our multiple-laser models – the JS-20 X2 or the JS-20 X3. The dual-laser X2 offers 12-inch spacing, while the triple-laser X3 provides 6-inch spacing.

The carriage headrig has continued to evolve with the industry – from manually operated to photo-cell arrays to front-side-only shape scanning. And today, complete-coverage 3-D scanning is the gold standard. JoeScan's complete-coverage 3-D scanning is based on our standard JS-20 scanners, known for their simplicity, flexibility and reliability.

Front and Back Advantage

By scanning both the front and back side of every log, our scanners provide the optimizer with a complete picture of the possible value of every log. The optimizer can then select a cut that maximizes that value.

Flexible Placement

The multiple-laser JS-20 X2 and X3 models offer a careful balance between cost and flexibility. Multiple-laser units can be individually placed and oriented to ensure every laser is getting a good scan, avoiding the many obstructions present in a mill environment and allowing the user to choose between 6- and 12-inch laser spacing, providing for the option of higher scan density if needed.

Our 24-head snapshot scanner has been running great since 2003. Even with nine heads riding on the carriage for Surround Scan, we've had no problems with the JS-20 scan heads.
