ABSTRACT:
A tool for assisting in manually raising a heavy elongate article off a firm surface, comprises a handle having a pair of co-acting part-cyclindrical jaw members disposed at one end for gripping the article to be raised. A fulcrum member projects from one of the jaws on which the tool can be pivoted to raise the article off the surface. During the raising process the jaws are held together by a second handle pivoted to the first in a scissors-like manner, or by a pair of pivoted locking arms.
