Abstract
A pulley suspension assembly for assisting a user to vertically transport a cable to an elevated location may include a base member adapted to be positioned at the elevated location. A plurality of prongs may be statically coupled the base, extended upwardly therefrom, and seated adjacent to a rear edge thereof. A rectilinear guide rail may be statically mated to the prongs and spanned therebetween. Additionally, a plurality of stabilizing brackets may be statically affixed to the top surface and front of the base member. Further, a rectilinear shaft may be connected to the brackets and spanned therebetween. A plurality of pulleys may be journaled about the rectilinear shaft and rotatable thereabout. Such pulleys may be uniformly juxtaposed side-by-side and freely reciprocated along the shaft while rotating about the fulcrum axis. Anchor cables may be included and engaged with the prongs and an existing support surface at the elevated location.
