The Multi Purpose Working Stand (MPWS) is designed to

enable maintenance operations on the roof, on the sides

and on underfloor components of rail cars. It consists of:

Roof Working Platform (RWP) with Train Driver Catwalk

(TDC)

Elevated Track.

WORKING PLATFORMSWorking platforms allow a quick, safe and easy access to the relevant workplace at side or on the roof of

the train by the staff. By moving the working platform close to the train the working risks are minimized.

ROOF WORKING PLATFORMSThe design of the roof working platform allows a

safe entering of the rail car roof alongside the whole

rail car length. The roof working platform will be

automatically moved gapless to the train.

FRONT WORKING PLATFORMSFor maintenance work at the front/nose of rail cars.

UNDERFLOOR LIFTING SYSTEMS for lifting / lowering trains for maintenance, repair and replacement of wheelsets, bogies and components.

The initial position of the Underfloor Lifting System is at "Zero" level (T.O.R.) which allows the unobstructed

use and passing of the main working level.

CANTILEVER DESIGNWith this kind of lifting system the bogies to be

replaced can be moved out and in beneath the

whole lifted rail car (train). This is especially

interesting for workshops with space constraints

COLUMN DESIGNThis kind of lifting system allows the replacement of

bogies and components directly behind the lifting

system.

DESCRIPTION OF COMPONENTS

ROOF WORKING PLATFORM (RWP) WITH TRAIN DRIVER CATWALK (TDC)

Supporting Structure welded steel construction hinged from the existing supporting structure of the

building

Platform structure hot dipped zinc coated corrugated steel

Side railing On each RWP, side rails are installed in the longitudinal direction (track direction)

for the safety of the working personnel

Movable Fall Down The Fall Down Protection at the front and rear of the RWP is movable in

Protection at front and longitudinal direction

Rear of RAP

Drive Unit It consists of a gear brake motor with drive shaft, pinion and toothed rack. The

ends of the drive shaft are additionally supported by bearings.

Stair cases The RWP is reachable via a staircase placed directly at the side of the columns

of the building structure.

Crane A crane with a capacity of two (2) metric tons including crane runway will be

provided

Supporting Structure welded steel beams with head and

foot plates..

Stairs, Emergency Exits Stairs, made of steel, are provided on

both ends of the pits for entry or exit.

These stairs are designed from floor

level (-0,0 mm) down to the mid

walkways (-1.750 mm).

One stair case to be installed on the

length of the elevated track of 70 m.

ELEVATED TRACKS WITH RAIL BRIDGES

Allow a quick change of wheelsets both with and without gear. The transport pallets support in an optimal

way the removal and installation. The change of underfloor components is also possible with great efficiency

IMAGE SHOWING ELEVATED TRACKS AND RAIL BRIDGES





WHEELSET CHANGER IN ELEVATED RAIL TRACKS WITH BRIDGES

A combination of wheelset changing system, low-floor lifting truck, body stands and changing cassettes in

the elevated track in connection with bridge elements. This is characterized by a very quick and space-

saving change of complete wheelsets

MOVABLE PLATFORMSAre an integral part of repair workshops in the heavy repair

of wagons and locomotives as well as in long-term

overhaul.

ELECTRIC COMPONENTS

DESCRIPTION OF ELECTRICAL CONTROL SYSTEMThe control system of the RWP will be activated by a key switch. The RWP system will be interlocked with the

existing security system of the workshop including interlock to existing Overhead Catenary System (OCS). The

telescopic platforms elements move out and in simultaneously. The end positions of the telescopic platforms

are controlled by limit switches and interlocked with the access entrance doors. The telescopic platforms

stop when a connecting block is activated or the telescopic platforms reach the limit switch.

Telescopic platforms touching the train will retract slightly for protection of the connecting blocks.

DESCRIPTION OF KEY EXCHANGE SYSTEMInterlocking with the workshop security system will be achieved by a Key Exchange System.

Only when theOCS is switched off, the grounding key can be removed from the related control cabinet of

the OCS. This key is the plugged into the key exchange system at the control cabinet of the RWP. The RWP

can only be operated when the grounding key is plugged in and turned.
