Transportation is the final step in the harvesting business to move all the logs or trees to the mill. Finally, they are forwarded to location e.g. the shipping yard in order to send for further transportation onwards.
There will be hardly any scenarios in the forestry business where the timber that is harvested will not be first moved by the truck to off-site.
Based on the distance that is needed to travel, trucking will always be too expensive components of the whole business of harvest. Therefore, it is very important that you must optimize the payload.
In most cases, it will mean that you need to maximize the payload. However, from the public point of view, all the log transportation is also one of the most visible parts of logging operation. Also, the transportation is affected by many different regulations.
Therefore, you can commonly find remorque à bois (English Meaning is wood loading trailer) in use for transportation.
Most of the trucks come in many different configurations. Also, they have certain pros and cons. One of the first consideration will be what form your product should be.
This may be logs, tree-length or short-wood, which is defined as logs and short enough to get stacked across deck of the truck or it can be in certain processed form e.g. wood chip. A consideration while selecting truck is machinery used for loading and unloading the trucks.
At the rear of the trailer, semi-trailers have wheels that are supported at front by the tractor that is attached to tractor by kingpin.
When it is not attached to the tractor, the trailer front must be supported, normally by landing gear or downriggers. Semi-trailers may have single, tandem or tri-axle configurations.
Full trailers will have set of wheels both at front and rear side of the trailer which are attached with the tractor, or some other trailer, with pintle and tongue hitch.
Usually, they never rely on tractor for supporting any of the load weight. Also, there is B-train configuration available with the tractor for pulling a 5th wheel dolly which supports smaller semi-trailer.
Straight truck will be a tractor having an extended chassis to carry load directly on tractor.
Axle configurations will be variable as well as important for the load capacity and also traffic ability on the soft roads (like any northern conditions during the break-up). Even weight distribution can also affect axle selection and also legal GVW that is Gross Vehicle Weight.
