ABSTRACT:
A multi-function logging machine is disclosed. The machine uses several simple components in various configurations to perform the functions of lifting, rolling, winching and holding a log, which can vary in size, in the field. The Logging Device replaces several devices that now must all be transported to the logging field with one easily transported unit. A body is provided in two feet. A handle fits through openings in the feet and is prevented from withdrawal and turning until released. A support member is mounted at one end of the body. An arm is mounted to rotate in the body. A claw with teeth is mounted on the arm. A cleat is mounted on the body opposite from the support member frame for preventing backward movement on a rope when the Logging Device is used as a winch.
