ABSTRACT:
Aid devices to facilitate the transport and raising of heavy ladders. To raise or lower the ladder, a lifter is provided in the form of a long pole having a transverse piece attached to one end thereof, the length of the piece being almost equal to the distance between the sidepieces of the ladder. Secured to the ends of the piece are resilient clips adapted to engage and clamp onto any rung of the ladder to be raised. In order to transport the ladder to a work site, a caddy is provided in the form of a pair of transverse pieces having clips installed thereon, the pieces being attached at spaced positions to the bridge of a two-wheeled carriage so that the pieces are adapted to straddle and engage a pair of adjacent rungs on the ladder in wheel-barrow position.
