Abstract:
A compressible stop for use in a crane has a housing, a rod slidably mounted within the housing, a floating piston, and a valve assembly. The floating piston divides the housing into a gas portion biasing the floating piston towards an end of the housing and a liquid portion containing a hydraulic fluid. The valve assembly divides the liquid portion into a support portion and a reserve portion. The valve assembly includes a check valve allowing a liquid to flow from the reserve portion into the support portion, a pressure sensitive valve inhibiting the liquid from flowing from the support portion into the reserve portion unless the pressure is above a threshold pressure, and a frangible divider configured to rupture when the liquid pressure exceeds a rupture pressure.

Claim (Index 17):
A method of allowing a support column pivotally mounted to a crane component to rotate beyond a normal stop position in response to a sudden load change, the method comprising:\n obtaining a crane that includes a compressible stop comprising:\n a housing including an internal cavity, a first housing end including a first interface interfacing with a first crane component, and a second housing end; \n a rod slidably mounted within the housing, the rod including a first rod end disposed within the internal cavity, and a second rod end located external to the internal cavity, the second rod end including a second interface for interfacing with a second crane component, wherein at least one of the first interface and the second interface is attached to one of the support column and the crane component and wherein the other of the at least one of the first interface and the second interface is attached to the other of the one of the support column and the crane component; \n a floating piston dividing the internal cavity into a gas portion biasing the floating piston towards the second housing end, and a liquid portion; \n a valve assembly dividing the liquid portion into a support portion and a reserve portion, the valve assembly comprising a check valve allowing a liquid to flow from the reserve portion into the support portion, a pressure sensitive valve inhibiting the liquid from flowing from the support portion into the reserve portion when a liquid pressure is below a threshold pressure and allowing the liquid to flow from the support portion to the reserve portion when the liquid pressure is above the threshold pressure, and a frangible divider configured to rupture when the liquid exceeds a rupture pressure; \n rotating the support column towards the crane component until the other of the first interface and the second interface contacts the other of the support column and the crane component; rotating the support column towards the crane component with the other of the first interface and the second interface in contact with the other of the support column and the crane component thereby compressing the compressible stop causing the pressure of the liquid in the support portion to reach the threshold pressure and to flow through the pressure sensitive valve into the reserve portion; and rotating the support column towards the crane component with the other of the first interface and the second interface in contact with the other of the support column and the crane component thereby compressing the compressible stop causing the pressure of the liquid in the support portion to exceed the rupture pressure rupturing the frangible divider.
