Abstract:
1. A portable power driven rope climbing apparatus comprising: a main support body; a power driven rotational input means mounted on said body; a drive shaft mounted on said body having a main pulley wheel co-axially mounted thereon; a gear reduction mechanism for transmitting a rotational force between said input means and said drive shaft; said main pulley wheel comprising engaging means for securely engaging a rope extending thereabouts such that rotation of said pulley wheel effects displacement of said rope; a rope input guide member and a rope output guide member for maintaining said rope in engagement with said pulley wheel about the majority of the pulley wheel circumference; and an attachment mechanism mounted on said main support body for releasably securing an external load thereto, and a rope entry guide member which supports said rope as it enters the apparatus and provides a fulcrum point about which the mass of the apparatus exerts a first moment, and wherein said attachment mechanism further comprises a seat member for suspending the load therefrom, said seat member being held remote from said main support body such that said load, when mounted thereon, exerts a second, opposed moment about said fulcrum, thereby causing pivotal displacement of the apparatus away from the load.
