Slab lifter

A slab lifter which comprises a pair of bars, pivot means for coupling said bars one to another to permit said bars to rotate with respect to each other about a mutually perpendicular axis, each said bar having at one end a slab-gripping portion bent at an obtuse angle A of 100 to 140 degrees towards the position of said slab-gripping portion of the other bar so that said slab-gripping portion can be inserted between adjacent slabs and together with the other slab-gripping portion can grip opposite side edges of a slab of distance L apart, the distance from said axis of rotation to said slab-gripping portion of one of said bars being approximately equal to 0.5 L/sine (A), wherein,

• said slab lifter further comprises stabilizer means adapted to contact a horizontal upper surface portion of said slab when said slab is gripped between said slab-gripping portions for stabilizing said slab when said slab is gripped by means of said slab gripping portions and lifted, said stabilizer means including a stabilizer member defining a substantially horizontal stabilizing surface and having one end rigidly fixed at a stabilizing position to said one of said bars such that said stabilizer member extends away from said one bar towards the other of said bars, said stabilizing surface thereby contacting said horizontal surface portion when said side edge, adjacent to said horizontal surface portion, is gripped by said gripping member associated with said one bar, and, wherein
• said bars extend on the other side of the axis of rotation and are of such length and shape that they project laterally at least as far as the vertical plane of the opposite edge of a gripped slab so as to provide handles.
