A compressible stop (100) for use in a crane (10, 50) is disclosed. The compressible stop has a housing (102), a rod (112) slidably mounted within the housing, a floating piston (124), and a valve assembly (132). 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 (142) allowing a liquid to flow from the reserve portion into the support portion, a pressure sensitive valve (140) 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 (138) configured to rupture when the liquid pressure exceeds a rupture pressure.
