A device for use by arborists for handling heavy tree limbs and main stems including a base for attachment to the tree trunk and a cylindrical member for receiving a rope mounted on the base. In an alternate form of the invention, the cylindrical member is mounted on an axle which is attached to the base and ratchets permit selective rotation of the cylindrical member in at least one direction. In still another form of the invention, a lever is attached to the cylinder to give an operator great mechanical advantage so that the device may be used to raise heavy loads by turning the cylindrical member.
