Loading a forwarder. Select the right statements! Several answers might be correct. Select ALL that apply!
What is the key goal when forwarding?
To finish the work as fast as possible.
All wood that is fit for sale should be forwarded to the landing.
Work very fast.
Forwarding in harvesting sites. Select the right statement!
It is the best way to begin a harvesting site from the nearest from the landing.
Logs are best loaded back and forth across the havesting site.
Start at the location furthest from the landing.
Maximizing quality by forwarding assortments in the correct order. Select the right statements!
The cheapest wood with the lowest volume is forwarded first.
Wood at risk of being downgraded due to fungal infestation should be prioritized for forwarding.
Wood should be properly sorted; this is done more easyily if the assortments are forwarded in a suitable order.
It is only important that the sawlogs are completely forwarded.
Example of forwarding in declining order of quality. Which one is the right order?
Special pine logs, normal pine sawlogs, small pine logs, softwood, fuelwood.
Fuelwood, normal pine sawlogs, special pine logs, small pine logs, softwood, small pine logs.
normal pine sawlogs, softwood, fuelwood, special pine logs, small pine logs.
Which is the right method when there is a risk that wood may be snowed over?
The prioritized wood method.
The trail by trail method.
Forwarding in declining order of quality.
Clearing a harvesting site containing snow-covered wood. Select the WRONG statements!
Consult with your supervisor and colleagues about the situation so that everyone involved works together and understands the objectives.
The trail by trail method should always be used
It is a good practise to place little flags in the snow coverd wood to find it.

Sometimes it is more effecient to load two or more assortments
It is forbidden to choose the combined forwarding when the wood is buried under snow.
If the forwarder needs only drive 20 meters to load up fully, the work will naturally be done more quickly than if it has to drive 200 meters to do so.
Combined forwarding needs more time for cleaning a trail.
What does skidding mean?
Skidding means to load one or more assortments into a forwarder without loading it to capacity and then forward them towards the landing.
Skidding means to forward the hole logs from one trail to the landing and piling in in single piles.
Skidding means, to grab a single big log and pull it out of the forest to the landing. These big logs are too heavy to load them up onto the forwarder.
When is skidding appropriate? Select the WRONG statements!
When you have long distances with 400 meters or more.
When you have short forwarding distances and high wood concentrations.
When you are forwarding wood over long distances across difficult terrain and the volume harvested per hectare is low.
