GRAVITY ACTUATED CRANE STOP

摘要

PROBLEM TO BE SOLVED: To provide a gravity actuated crane stop of a crane.SOLUTION: A gravity actuated crane stop 300 has a first connector at a first end configured to couple to a first crane member and an interface 308 at a second end 306 configured to couple with a second crane member. A gravity actuated mechanism 312 is disposed on a body 302 and has a first configuration in which the gravity actuated mechanism 312 disables the interface 308, and a second configuration in which the gravity actuated mechanism 312 does not disable the interface 308. The gravity actuated mechanism 312 is automatically changeable from the first configuration to the second configuration as the body 302 is moved from a first orientation relative to a horizontal plane to a second orientation relative to the horizontal plane.SELECTED DRAWING: Figure 3
