Lifting clamp
Provided is a lifting clamp capable of automatically tightening at the same time as lifting while having a simple configuration. A lifting clamp 1, wherein a body 2 has a pair of facing pieces 2a, 2b arranged so as to face each other so as to form a gripping space S where an object to be transported can be gripped. The gripping space S side of each of the facing pieces 2a, 2b has a contact portion 4, 5 that makes contact with the object to be transported. A handle 8 is attached to the body 2 so as to be pivotable about a pivot shaft that is disposed along the gripping direction shown by the alternate long and short dash line. The present invention is equipped with a conversion portion 10 between the contact portion 4 and the facing piece 2a, the conversion portion 10 converting the rotational movement by the turning of the handle 8 into a gripping movement that pushes the contact portion 4 in the gripping direction. The contact portion 5 is attached to the pivot shaft 17 that supports the handle 8 on one side, and the size of the gripping space S can be changed by sliding the pivot shaft 17 with respect to the facing piece 2b. The slide position of the pivot shaft 17 is selectively fixed by a plunger 19.
