Not only are these two elevator special in that they open up to the street, but they also have a rather long travel distance for being hydraulic. The drive sytem these use would normally be called "holeless", as the piston is attached to the car top, avoiding the need to drill a hole for the cylinder. This does not quite hold true here, since each of the piston's three segments has to be at least two floors tall.

Brand: Dralle
Capacity: 600kg / ~1325lbs / 8 people
