Abstract: A method of logging utilizes a combination log yarder and processor vehicle having a basic vehicle structure not unlike that of a track-type excavating machine, but with a boom arm assembly arranged for operation in conjunction with a log processing head apparatus and its particular requirements for the handling and processing of felled logs and trees. The vehicle mounts a collapsible yarder tower arrangement which rotatably mounts a cable guide head member for relative rotation between the cable guide head and the vehicle on the same center axis of rotation as the vehicle turntable rotates on its undercarriage, thereby permitting the vehicle full rotational capabilities and operation of its boom arm apparatus when the yarder apparatus' cables are extended and anchored and in operation, and thereby permits a yarding operation of felled trees to be conducted simultaneously with a log processing, log sorting and log loading operation by a single personnel at a destination location at a logging site.

Abstract: A vertical lift hoist and winch is taught which can be used, for example, for suspending wild game animals for the purpose of field dressing. The assembly is collapsible without any disassembly of major parts, to be able to fold up into a convenient carrying position, or to be capable of storage in a normal automobile truck, Jeep or station wagon compartment or a truck tool box. The winch lift assembly permits convenient storage and ease of set-up, where all pieces are held together as one. The pulley's are recessed in the upper boom which allows a tight closure in the collapsed position which is an advantage over other types of lifts. Nothing hangs down below the boom, thereby eliminating any cable tangles or interference when setting up or storing.
