The cradle with rollers that roll down the trackway and then down the ship's side into the water is associated with which gravity davit type?

Gravity davits use the weight of the boat to lower it safely into the water. The Miranda gravity type is defined by a cradle that sits on rollers and runs along a track, then continues down the ship’s side into the water when released. That arrangement—cradle with rollers riding a track and guiding the boat over the edge—is the hallmark of the MIR gravity system. Other terms describe more generic lowering gear or different configurations and don’t specify this track-and-roller mechanism, so they don’t fit as well.
