LADDER-MOUNTED MATERIAL LIFT
A ladder-mountable material lift for mounting on an extension ladder, having a hoist for engaging with an upper rung of the extension ladder and a platform moveable by the hoist between a lower end of the extension ladder and the hoist. The platform has upper and lower side brackets on each side of the platform, the lower side brackets for sliding along upper surfaces of the side rails of the ladder base section and the upper side brackets for sliding along upper surfaces of the side rails of the ladder fly section, such that operation of the hoist causes the platform to move upwardly or downwardly along the extension ladder.
