For this type of application, very specialized equipments
are generally used in order to be achieve
maximum efficiency with the complete free fall of
the weight, generally through the use of a specially
designed weight release system (hydraulic clamps,
hooks..). After an initial phase with equal acceleration,
the clamping device releases the weight in total free
fall (no damping or friction effect from the winches or
cables). After the impact, the device grabs the weight
