A device for absorbing shocks of a liftable and lowerable object such as a spare tire includes a first hoisting cable having a hoist-side end and an object-side end and a hollow cylinder encompassing a folded or coiled length of the first hoisting cable near the object end inside the cylinder. Lower and upper ferrules at the lower and upper ends of the cylinder are held in position by a second auxiliary cable having two ends, each end attached to one of the ferrules, the second auxiliary cable having a smaller tearing strength than the first hoisting cable.
