Forwarder

The forwarder is a rubber-tired or tracked machine used for the extraction of trees. Other machines that can be used for this sub-process are the cable skidder, grapple skidder, clam-bunk skidder, farm tractor equipped with a forwarding trailer, and cable yarder.

The forwarder is mainly utilized for the extraction of short logs with a maximum length of 6 m (so called crane length).

An integrated grapple loader lifts the logs onto the forwarder, where the logs are held by stanchions. Since the load does not touch the ground during the transportation process from the trail (buffer 32) to the forest road (buffer 33), this type of extractions is assigned to the carrying extraction.

The forwarder is commonly used in combination with a harvester. The combination of both machines is called “fully mechanized cut to length method” or short “cut to length method”.

A farm tractor equipped with a forwarding trailer is also used in some cases as a substitute for the forwarder.

The work with the forwarder is described as advanced mechanized work.
