ABSTRACT:
A lifting aid attachment for a conventional snow shovel or like tool features an elongate lever arm pivotally attached to the shovel handle, the opposite end of said lever arm terminating in a curved fork, spanned by a foot-engaging cross-bar. The curved fork serves as a fulcrum for the application of downward foot pressure by the user on the cross-bar, which combined with a rearward pull on the shovel handle enables a smooth and comparatively effortless raising of the loaded shovel to hip level, substantially free of the high stresses on the back, upper body and arms that accompany the use of conventional shovels. At the top of the lift the lever arm is suitably biased to support the raised load stably in a "cradled" position, requiring minimal effort by the user, prior to disposal of the load. Where desired an additional leg may be pivotally attached to the free end of the shovel handle, and enable the hand-free tabling of the raised load. Variations of the invention are suitable for use with lifting poles and other long-handled tools.
