Rollout Scaling
Particularly where high value logs are involved a preferred method of scaling is a 'roll out' method. In this process the logs are removed from the truck and rolled out on the ground or on skids a single layer deep. The scaler can then see a good part of every log to assist in determining what if any defects it may have such as sweep, or rot. Roll out scaling has to be done where heavy machinery is available to handle the logs, and requires the space to do the rollout, and time and expense of the extra handling. If handled correctly, rollout scaling can be more efficient (at least for the trucks) as the trucks do not have to wait to be scaled and can be unloaded and leave immediately. This contrasts with the ramp scale where the truck must wait with the load until the scaling is complete.
