Abstract
A gravity actuated crane stop for a crane is disclosed. The gravity actuated crane stop has a first connector at a first end configured to couple to a first crane member and an interface at a second end configured to interface with a second crane member. A gravity actuated mechanism is disposed on the body and has a first configuration in which gravity actuated mechanism disables the interface, and a second configuration in which the gravity actuated mechanism does not disable the interface. The gravity actuated mechanism is automatically changeable from the first configuration to the second configuration as the body is moved from a first orientation relative to a horizontal plane to a second orientation relative to the horizontal plane.
