Hydraulic elevators are proper solutions in places which is
not so busy and which is not possible to establish an engine
room in the upper part. It is applied generally in freight
elevators. The roof problem in factories can be eliminated
by hydraulic elevators.
Dumbwaiter type elevators have generally guillotine type doors.
Guillotine doors not only has great facility in working for the user
thanks to its opening and closing by a simple movement, but also
does not occupy space when they’re opened as the semi-automatic
doors do. Stainless steel cabinet and doors are always preferred
since they must be hygienic.
