ABSTRACT:
A device for climbing a tree, pole, or other vertically elongated generally cylindrical device is disclosed which comprises an operator's basket, a pair of identical hangers adapted to encompass the object to be climbed, and to be adjustably supported at selected elevations thereon, one above the other, and a block and tackle assembly which the operator connects between the uppermost hanger and the basket to move the basket with the operator therein relative to the uppermost hanger. The bottom hanger is used to support the basket in a fixed position while the upper hanger and upper block is repositioned further up the tree when climbing or further down the tree when descending. Alternate moving of the hangers, which alternately supporting the basket from one and then the other of the hangers, followed by raising or lowering the basket with the block and tackle assembly enables the operator to climb or descend the tree.
