Abstract: A system for a climbing apparatus including a housing assembly, a wheel assembly, a lock assembly, a rope assembly and a chainsaw assembly is disclosed. The housing assembly includes a housing having a rope wheel therein. The housing is mounted to a chainsaw to power the components within the housing to allow a user to ascend and descend a structure. The rope is secured to the top of a structure and then mounted to the rope wheel at an opposite end. The chainsaw is actuated to also actuate rope assembly. The rope wheel rotates to allow for rope to be fed, allowing a user attached to the housing to ascend or descend, as needed. With the lever the user may lock the rope in place to allow the user to work at a desired height on a structure.
