WITTUR SOLUTION FOR MODERNISATION
The MRM W Line, Wittur flexible machine roomless
electric lift, offers an ideal solution for new lifts in
existing buildings based on an innovative modular
design.

www.wittur.com
The MRM W Line is designed for space optimization:
width and length of the car can be adapted to fit
the biggest car into the existing shaft dimensions.
The MRM W Line offers a package with reduced
energy consumption for buildings with up to 10
stops and a travel height of up to 30 m, with a
maximum rated load of 1000 kg (under development) and a maximum rated speed of 1 m/s.
NORMS COMPLIANCE
The MRM W Line fulfills all the requirements of the
Lift Directive 95/16/EC, as well as the standards
EN81-1:A3, EN81-28 (remote alarm on passenger
and goods lifts) and EN81-58 (landing door fire
resistance test).
Wittur additionally offers the option of supplying
the MRM W Line to comply with EN81-70 (designed
to improve accessibility), EN81-73 (behaviour of lifts
in the event of fire) and EN81-21 (reduced pit and
head room).
Upon request, the MRM W Line can be manufactured to comply with the standards EN81-72 (firefighters lifts) and EN81-71 (vandal-resistant).

QUICK INSTALLATION
The MRM W Line is easy and quick to install.
A new modular logistics concept has been designed
so that each box is opened only as and when its
contents are needed, thereby avoiding time
wastage, confusion and loss of components.
Furthermore, each component has its own
user-friendly manual, making the steps of the
assembly process easy to follow and fail-safe.
The assembly of the electrical components has also
been made simpler thanks to Wittur “Plug and Play”
concept.
ADVANCED FEATURES
MRM W Line
LOW MAINTENANCE
The MRM W Line requires minimal maintenance due to the high quality
and simplicity of its design.
Besides avoiding unnecessary costs, this adds to the safety of the
assembly and maintenance personnel.
REDUCED ENERGY CONSUMPTION
The MRM W Line offers low energy consumption thanks to its efficient
ECO design.
Both the gearless drive motor (WSG T-Series) and the car door motor
(ECO / MIDI / SUPRA) incorporate cuttingedge technology in the form of
permanent magnets which guarantee reduced energy consumption
during the running of the lift, and whose “Sleep Mode” (upon request)
reduces energy consumption to “0” Watt when the lift is not being used.

Wittur Inside: the MRM W Line incorporates components manufactured
by Wittur to the highest standards of quality, reliability and safety.
COMPACT & FLEXIBLE DESIGN
Subject to change without notice !
The MRM W Line makes optimal use of available space and can be
installed in any type of shaft with a pit depth starting at just 320 mm
(only for 320 kg version) and headroom starting at just 2800 mm (both
according to EN81-21).
The MRM W Line uses Wittur bedplates and WSG T-Series gearless drive
which offers smaller dimensions through the use of smaller traction
sheaves with reduced rope sections.
The compact design do not compromise a wide range of door installation: all Hydra, MDS1, Fineline, Ecobus, and Swings series are available
with 1 or 2 entrances (2-90º / 2-180º) option.
Furthermore, the controller is perfectly integrated into the design of the
elevator, fitting snuggly into a compact controller cabinet placed neatly in front of the frame of the landing door itself.
MRM W Line 320 dimensions are suitable to be fitted into existing
hydraulic lift shafts for modernisation purposes.
ADVANCED FEATURES
MRM W Line
A SILENT AND COMFORTABLE RIDE
Through the combination of highly efficient mechanical and electrical
components (like the gearless drive), the isolation of vibrating elements,
drive control by means of a frequency inverter, balanced rope arrangement and low friction sliding guide shoes, it has been possible to obtain
a high ride comfort and low noise levels compliant with VDI 2566-2.
The optional “Comfort Kit”, silent blocks made of platted stainless steel
wiring, offers a reduction of up to 15% in the level of vibration of the
drive, obtaining an enhanced ride comfort and preventing any vibrations
from travelling through the building. In particular, the system is
equipped also with a special drive and traction ropes isolation (320 kg
version).
The consequent noise level perceived by the passenger from inside the
car is limited to 50 dBA.

OPTIMISED PACKAGING
The elevator’s sub-components are delivered in pre-established space
saving and highly recyclable modules which have been clearly identified
and numbered according to the order in which they are needed within
the elevator’s assembly sequence.
This greatly optimises handling and increases safety during transportation.
03_feb_2014
Once the contents of the box have been used, the box can be removed
from the site and recycled.
AVAILABLE FINISHES
Despite its simplicity, the MRM W Line offers a wide and versatile range
of options and car decorations.
The standard decorations, with their functional designs, offer the added
advantage of a short production lead-time, but the MRM W Line can be
supplied in a most versatile range of decorations to suit any request
including skinplate, melamine, laminate, wood, stainless steel and glass.
