ABSTRACT:
An easily transportable self-powered conveyor device, for use e.g. in transporting pieces of wood over rough terrain, has a drive chain and driven disc installed on a chainsaw in place of a saw chain and bar, the drive chain being in driving engagement with the driven disc. A sheave is connected to an output of a reduction gearing for rotation thereby and a rope extends around the sheave, with securing devices attached to the rope and spaced apart along the rope for temporarily securing objects to the rope for conveyance thereby as the rope is pulled by the sheave. A retaining device anchors the sheave to any suitable support, e.g. a tree.
