Abstract
According to one or more aspects of the invention an interlock device is adapted for connection within a load path of a tubular support device to lock the tubular support device in a closed position in response to detecting a load suspended from the tubular support device. The interlock device includes a first member moveably connected to a second member and a biasing mechanism operationally connected to the first member and the second member providing a load setting resisting movement of the first member and the second member relative to one another. The first and the second member may be rotationally locked with one another to transmit rotation across the interlock device to the elevator.
