MRL hydraulic elevator with power unit in the shaft at landing level
The Superidrofit elevator model has the power unit inside the elevator shaft. The controller and all electric equipments are placed inside a cabinet next to the landing door frame.
No machine room needed. Main switches, thermostat detecting the temperature of the area, lamps, are inside the cabinet next to the landing door frame. The floor where the power unit and electric equipments are located can be the lower, any intermediate or the upper floor. The minimum dimensions of the headroom and the pit are the same as for a standard elevator with a machine room. In other words the power unit in shaft does not affect the pit and headroom dimensions. Power unit and controller are very close to each other. This simplifies assembling, maintenance and rescue operations. The power unit is very slim; so the shaft size is not increased due to this component. Available layouts: 1 car entrance, 2 opposite, 2 adjacent entrances.
Rescue operations are carried out from the landing by opening the cabinet door frame where the power unit is located. The power unit is extractable onto the landing floor, so that inspection and maintenance operations can be very easy. Rescue operations can be also carried out without extracting the power unit. Maintenance operations do not need to be carried out from inside the shaft as it happens with a hydraulic elevator model with the power unit inside the pit. With Superidrofit, power unit components can be adjusted from the landing floor.
