WITTUR’S SOLUTION FOR MODERNISATION
The MRM W-Line, Wittur’s flexible machine roomless electric lift, offers an ideal solution for new lifts in existing buildings based on an innovative modular design. The MRM W-Line has been designed specifically to permit optimised use of space and energy consumption in buildings with up to 10 stops and a travel height of up to 30m, with a maximum rated load of 1000 kg and a maximum rated speed of 1 m/s
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, subject to technical feasibility analysis) and EN81-71 (vandal-resistant).
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 and confusion. 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’s “Plug and Play” concept. All the customer has to do is connect the components as instructed in the manuals.
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.
Wittur Inside: the MRM W-Line incorporates components manufactured by Wittur to the highest standards of quality, reliability and safety.
REDUCED ENERGY CONSUMPTION
The MRM W-Line offers low energy consumption thanks to its efficient ECO design. Both the gearless drive motor and car door motor 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” watts when the lift is not being used.
COMPACT AND FLEXIBLE DESIGN
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 does 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 can be 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 (technical study requested in case of reduced headroom). MRM W Line 320 dimensions are suitable to be fitted into existing hydraulic lift shafts for modernisation purposes.
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. The noise level perceived by the passenger from inside the car is limited to 50 dBA.
A new and user-friendly logistics concept has been designed for Wittur’s new range of elevator systems. The elevator’s sub-components are delivered in pre-established spacesaving 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. Each module is easily identifiable and is opened only when its contents are needed, thereby increasing the ease of assembly whilst dramatically reducing the risk of loss of components from boxes that have been opened before it was necessary. Once the contents of the box have been used, the box can be removed from the site and recycled.
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.
