Forestry Equipment Operations Final Test

Some of the CONS to using the fishbone on two sides harvesting method are:
– smaller piles ( hard to find wood in snow conditions)
– long reaches for harvester to the outside sections
– felling direction must be right

The following factors affect forwarding time:
– cutting type, clear cutting or selective cutting
– average forwarding distance
– cutting scheme ( fish bone, one side, two side, etc) log or pile location on the strip road
– volume m3/m on strip road
– number of assortments
– forwarder load space size
– terrain, weather, circumstances,
– operator skills

Some of the PROS to using the 90 degree one side method are:
– large piles of wood
– easy to forward
– nice looking job
– easier to find wood in the snow

Differences between the operators in productivity and effectiveness come from: 1) how to handle the crane, 2) how to plan the work. With experienced operators the main source of differences is planning.

Cut to length method is using the harvester to cut the product logs in the bush to the desired length, whether it is 9′, 10′,12′ etc.?

The four forwarding phases are: 1. driving empty, 2. collecting the load, 3. driving loaded, 4. ?

Some of the PROS of using the fishbone on two sides harvesting method are:
– most efficient method of harvesting
– regeneration protection
– helps forwarder operator sort different products
– best brush management
– can see the butt of the tree

Some of the reasons for using the cut to length process are:
– social & public acceptance of logging in general
– outcome from forest higher for landowner
– quality of work better, future outcome from the forest better
– pressure for certified wood products and paper from end users

Some of the CONS to using the 90 degree two sides harvesting method are:
– smaller piles, hard to find in snow conditions
– not as efficient as fishbone two sides
– can’s see but of tree
– destruction of advanced regeneration
– falling wood on piles in adjacent trails

The three main cut to length harvesting methods are:
– 90 degrees on one side
– 90 degrees on two sides
– fishbone

Some of the flexibility benefits of cut to length are:
– minimum preparation of landings required before start of production
– suitability to thinning and regeneration operations with same machines
– smaller jobs can be operated economically
– only two machines to move from site to site
– scheduling is easier – less machinery, less people

Some of the PROS to using the 90 degree two sides harvesting method are:
– less travel distance for the boom
– more room to keep different products separate

Some of the benefits to Multi-Stem Harvesting (MSH) are:
– less movement of the crane per tree
– less feeding per tree
– less sawing per log

Some of the CONS to using the 90 degree one side method are:
– very inefficient ( lots of wasted boom movements)
– can’t see the butt of the tree
– hard to get the tree down falling into standing wood

Some of the environmental benefits of cut to length are:
– minimum ground disturbance
– suitable for selective harvesting and thinning
– minimized the damage to residual stand
– tops and branches are evenly spread on the logging site (minimized nutrient loss)
– suitable to sensitive and soft ground
