Abstract: The present invention discloses methods and apparatus for pre-bunking cut timber and transporting cut timber. A plurality of portable U-shaped bunks or cradles are first releasably attached to a portable skid, and logs are loaded onto the cradles. In an embodiment, the cradles are collapsible. This step may be performed before a transportation trailer is on site. The load of logs, with the portable cradles are then moved as a unit and attached to the trailer. The trailer is provided with attachment hardware adapted to releasably engage the portable bunks. In an embodiment of the invention the trailer attachment hardware is removably attachable to the trailer, permitting the trailer to be used for other purposes. The present system permits improvements in efficiency by permitting logs to be pre-bunked while the trailer is in use elsewhere.

Abstract: A trailer (100) is disclosed having a trailer bed (106) that may be a drop center type trailer and a frame structure extending, including a forward frame (120), rearward frame (122) and upper beam (124) therebetween. Pivotable bunk assemblies (150, 160) having left and right portions are pivotably mounted to the trailer side rails (105), the bunk portions pivotable between a deployed position extending over the trailer and a non-deployed position. A top frame (130) is hingedly attached to the upper beam and engages the bunk assemblies when it is in the closed position. Deployable, load-bearing sidewalls (102) are also optionally provided. The trailer is easily convertible between a configuration suitable for hauling logs in the deployed bunk assemblies and a configuration suitable for hauling other product—for example, wood chips or the like—with the bunk assemblies non-deployed, and the sidewalls deployed.

Abstract: The present invention discloses methods and apparatus for pre-bunking cut timber and transporting cut timber through the use of a trailer that is adapted to receive portable bunks. Methods and apparatuses of the present invention include a pre-bunking system connected to a scale with a remote readout that can permit the operator to vary the load of logs to be transported. Additionally, methods disclosed by the present invention permit efficient transportation of both logs and wood residuals (or any other load) with a minimum waste of labor and fuel by permitting return trips of wood residuals or other load away from the sawmill or other location, such as a pulp mill. Wood products or any load that can be efficiently used to maximize the value of transportation may be hauled according to the claimed invention.
