Abstract
A clamping device for lifting and transferring objects can employ slanting interfaces to convert a pulling action on the clamping device to a clamping action on the object. A pulling element in the form of a triangle can be disposed between a jaw and a jaw support of the clamping device. When the pulling element is pulled up, the base of the triangle shape pulling element can exert a force on the jaw against the jaw support, for securing a gripping action on the object.

A clamping device comprising
- a clamp bar;
- a first jaw assembly coupled to the clamp bar,
- wherein the first jaw assembly comprises a first jaw;
- a second jaw assembly coupled to the clamp bar,
- wherein the second jaw assembly comprises a jaw support,
- wherein the second jaw assembly comprises a second jaw,
- wherein the second jaw is coupled to the jaw support,
- wherein the first jaw and the second jaw are configured for clamping on an object,
- a pulling element interfacing with the jaw support and the second jaw,
- wherein at least one of the interface between the pulling element and the jaw support and the interface between the pulling element and the second jaw comprises a slanting interface,
- wherein the slanting interface is configured so that when a force is applied to the pulling element in a direction comprising a vertical direction, a second force is generated pushing the second jaw in a direction comprising a direction from the second jaw to the first jaw.
