If this was a usual telescoping holeless hydraulic elevator, it would not be anything special. But on this one, instead of extending both parts of the piston simultaneously, first the upper part is extended until the top of the lower part is seemingly caught by the cab. Finally said lower part of the piston is extended. This is hardly, if at all, noticeable while riding.

Brand: Dralle
Capacity: 630kg / ~1390lbs / 8 people
Type: hydraulic (holeless two-stage, stages extending seperately)
Year built: 1990
Travel distance: 2 floors
