1. A clamping device comprisinga connection element;
- a first jaw coupled to the connection element;
a jaw assembly,wherein the jaw assembly comprises a second jaw and a jaw support,wherein the first jaw and the second jaw are configured for clamping on an object,wherein the jaw support is coupled to the connection element,wherein the second jaw is movably coupled to the jaw support at least in a direction away from the jaw support toward the first jaw,wherein the jaw support comprises a metal core at least partially embedded in a jaw support body,wherein the metal core is configured to provide a structural support for the clamping device,wherein the jaw support body comprises a material different from the material of the metal core,wherein the jaw support body comprises a hollow portion mating with the second jaw as a lid,wherein the hollow portion comprises a dimension between the second jaw and the jaw support that is larger at a location farther from the connection element than at a location nearer the connection element;
a pulling element,wherein the pulling element is partially disposed in the hollow portion formed between the second jaw and the jaw support,wherein the pulling element comprises rollers, wherein one or more first rollers of the rollers are configured to roll on a first surface of the jaw support, wherein one or more second rollers of the rollers are configured to roll on a second surface of the second jaw.

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. Components of the clamping device can include a metal core embedded in a body of a different material. The embedded core construction can allow a simplified fabrication of the clamping device for high stresses, high forces, high durability and high reliability.

16. A method to form a clamping device, the method comprising
forming a connection element; -
forming a first jaw; coupling the first jaw with the connection element; forming a second jaw; forming a jaw support; wherein the jaw support comprises a metal core, wherein the metal core is configured to provide a structural support for the clamping device, wherein the jaw support comprises a jaw support body surrounding the metal core and protruding from the metal core, wherein the jaw support body comprises a material different from the material of the metal core, wherein the jaw support body comprises a hollow portion mating with the second jaw as a lid, wherein the hollow portion comprises a dimension between the second jaw and the jaw support that is larger at a location farther from the connection element than at a location nearer the connection element; coupling the jaw support with the connection element; coupling the second jaw with the jaw support with springs; forming a pulling element, wherein the pulling element comprises rollers; placing the rollers in the hollow portion between the jaw support and the second jaw, wherein one or more first rollers of the rollers are configured to roll on a first surface of the jaw support, wherein one or more second rollers of the rollers are configured to roll on a second surface of the second jaw.
