ABSTRACT:
A tong apparatus having first and second hand grippable members, a first work gripping element associated with the first hand grippable member, and a second work gripping element associated with the second hand grippable member, the improvement comprising structure for amplifying movement of the first work gripping element relative to movement of the second work gripping element and also relative to the first hand grippable member, in response to relative movement of the first and second hand grippable members. Amplification of motion of the work gripping elements is provided, aiding in pick-up of both large and small work pieces. The surfaces for the operator to grasp are long enough that two hands may conveniently be used, if required, for heavy loads.
