ABSTRACT:
A pulpwood harvesting system for cutting and transporting trees upon a fragile terrain so as to have a dispersed and minimal impact on the terrain. A rail network is supported above the surface of the terrain upon spaced vertical pilings. Trees are cut and reduced to bulk by a mobile tree harvester and transported to the rail network by a mobile forwarder. The tree harvester and forwarder move upon tracks or other means to disperse their weight. The rail network is progressively installed by a mobile rail layer supported upon previously installed rails. Automated lorries receive the bulk pulpwood and transport it upon the rail network to a distant unloading site.
