Another of our projects of mobile machines is a series of special vehicles – aerial work platforms - on truck chassis designated as service vechicle for railways' catenary lines;

Renault Midlum (DMC 15 T and DMC 18T) - vehicle with a cab of two rows of seats, equipped with a swivel arm with an electrically insulated wooden work platform.



The machine is intended for automatic twisting a mesh of a wire 2.0 to 4.0mm thick. The mesh fizible size is 40 to 60mm. The grid is formed by winding two wires at the same time to a rotating spindle made of a flat bar. At the same time with the winding, the wire slides from the flat bar towards the winding of the finished net. The wire is automatically cut off after reaching a fixed number of turns and the finished net is rolled into the roll at the base of the machine. Machine operation (ie mesh width, number of rolled wires, operating speed) is controlled by a PLC

For our client we have analyzed and developed the technical documentation of the CE marking:
- design analysis, selection of machine specific directives, selection of conformity assessment procedures,
- analysis of hazards arising from the use of the machine together with the warning and information signs,
- analysis of compliance with the essential requirements of EC directives,
- development of instructions for use in accordance with the requirements of the machine directive,
- develop the EC Declaration of Conformity.
The machine meets the requirements of the directives:
2006/42 / EC - Machinery Directive,
2006/95 / EC - Low Voltage Directive,
2004/108 / EC - Electromagnetic Compatibility Directive.

gearbox2Special construction of gearbox have been designed and manufactured by our team and cooperators. The gearbox is intended to transfer momentum from vehicle tires' (by direct contact) to rail wheels'. The vehicle design speed is 70 km/h forward and 15 km/h backwords. The gearbox can be also supplied for various different design requirements.


The reason of double track vehicles, called Road-rail vehicles, is not a travel on both road and railways but they are built for service actions and works provided on railways inaccessable by road. The vehicle have to access the railway at the crossing with the road and then is able to continue the traver on rails.

Our RoadRail vehicle has been built on 4x4 chassis of MAN TGM. Cabin of that vehicle can accommodate 5 people + driver.

Rail drive of that vehicle consists of 4 solid steel hweels that takes power from a road tires by a drum installed by each wheel and hense is able to brake by all 4 wheels as well.

We've already designed and built a number of road-rail vehicles intended for drive on trams' and trains' traks of gauge 1000 mm and 1435 mm and we are able to provide vechicles for any other rail sizes.

We can provide completed commercial vechicles equipped with front or rear crane, elevating work platform of various size, capacity and outreach or provide naked rail chasis for your company assembly as well as bespoke design for your poduction.


Forward drive speed - 70 kph (electronically restricted to 60 kph)

Backwards drive 14 kph

Max total mass of the vechicle 18 ton


The base chassis (MAN TGM) is equipped with automatic type gearbox containing 12 forward and 2 revers stages. MAN PKP3

road rail daily 1 

Next of our road-rail commercial vehicles ! 

The vehicle built on IVECO DAILY chassis works as service - emegrency truck in company WARSAW TRAMS in Poland.

The vehicle has relatively low frame thats why we had to use small rail wheels and foldable rail chassis. The wheels are driven by a pair of hydraulic motors that can achieve travel speed of 13mph (20 km/h)

The best place to maneuver our vehicle on and off rails is a rail-road crossing. The short rail axles gap makes the operation very easy.

The built-on container contains equipment and tools for restoring the tram that happened to fall out. In order to facilitate the staff work, we have built-on HDS crane of capacity 3.4 tm at the rear of the vehicle

The road-rail vehicles' drive system can be open or closed circuit. In this construction (IVECO DAILY) we've made closed circuit oil system. Driving power is supplied from main gearbox of the vehicle by power take off adaptor. The multi-piston hydraulic pum of variable displacement, driven by the power take off adaptor, supplies 2 motors assembled at front rail wheels (more loaded pair of wheels). Driving speed is controlled by both engine speed and the main pump displacement volume and due to that we achieve good acceleration at small vehicle starting as well as good travel speed up to 20 kph. The variable displacement pump provides also smooth and efective decelerating and backwards drive at the same max speed. Main motor and power take off adaptor rotates the same direction at both forward and backward travel of the vehicle.

Equipment installed on the vehicle like: rear loading crane. rail wheels' swingarm folding cylinders, powered by a separate external gear type pump driven by the same power take off of the engine gearbox. Solenoid-and-manual operated levers' of multi-valve block are used for control of all the drives (all but wheel drive).

Radio controll of the crane is a standard equipment of most of HIAB models and many other cranes'.

working platform on tractorTractor mounted work platform was designed by our team for extremely hardly reachable places, ex. in fields or forests where no roads reaches.

Telescopic arm is instaled on rotatable column and fixed to a tractor by special frame construction. The frame has pairs of frond and rear outriggers.

Machine conforms requirements or Machinery Directive 2006/42/WE and european standard EN 280


Working platform operation zone is 21m high and 9m wide.


Towable work platform is designed as single-axle trailer with drawbar of adjustable height and overrun brake. Work platform is placed on single (or telescopic) arm with articulated maneuvering extention - JIB.
