A key difference between old and modern lifts lies in the machine room. Time ago nearly all lifts in the 1.0 m/s category required one above the shaft to accommodate the bulky drivetrain and the controller. Around the 2000s technological progress enabled smaller components, and machine room-less lifts came about to make do with a shaft that needed to offer just a bit more headroom above the top landing. Measured from the finished floor of the top level, a typical standard shaft head for a machine room-less elevator is around 3.400 mm. With the option of the extra-reduced shaft head EOX Rebuild now will fit within standard room heights of as little as 2.500 mm at the top floor. This means: Whichever type your outgoing elevator is, replacing it with EOX Rebuild won’t give you any headaches – except maybe having to decide what to do with the old machine room.

Benefits of the extra-reduced shaft head
Machine room to repurpose
Because all components of EOX Rebuild are located inside the shaft, a machine room is no longer needed and can be used, for example, as a storage space.
Maintenance from the cabin
On standard machine room-less elevators, technicians service the components in the shaft head from the cabin roof. EOX Rebuild comes with a ceiling-integrated foldable platform, enabling all maintenance tasks to be performed from within the cabin. It’s safer and quicker.
Exceptionally quiet
If the noise from your old lift’s machine room is making you hesitate: Performance data proves that EOX Rebuild is a quiet lift system. The entry value (at 630 kg, 1 m/s) of just 24 db(A) in adjacent rooms means that an EOX Rebuild from next door is quieter than a whisper.
Reduced shaft pit
Optionally, EOX Rebuild is also available with a reduced shaft pit. The minimum achievable height is as low as 450 mm, instead of the standard 1.000 mm. It can be combined with extra-reduced shaft head, although restrictions may apply.
Certified solution
The options for the extra-reduced shaft head and reduced shaft pit are type-tested and conform with the latest regulations like EN 81-20/50 and EN 81-21.

Further information on the application of extra-reduced shaft head
The extra-reduced shaft head and reduced pit options are available for EOX Rebuild elevators with max. 1 m/s. Extra-reduced shaft head is applicable to standard dimension cabins and also when flexible cabin dimensions are applied. Cabins are exclusively available with Steel Lightbox and Steel Grille ceilings. Minimum achievable shaft head is dependent on the chosen rated load, cabin height, door height and door type as well as door model. For example, the lowest extra-reduced shaft head of 2500 mm is achieved at 630 kg with 2100 mm cabin height and a low-buildup door model of 2000 mm height. Combination of extra-reduced shaft head and reduced pit (min. 450 mm) is possible, although restrictions may apply depending on the specific configuration of your EOX Rebuild elevator.
