Design, manufacture and supply of Road/Rail Vehicles
Why is RailPro different?
RRVs have a long history, but until now, the transmission mechanisms used have been heavy, energy inefficient, and cumbersome.
How Does the DSDS™ Work?
RailPro have patented a unique system where the engine power is transmitted through the gearbox as per normal road use. A transfer box is located between the gearbox and the truck differential. This is used to divert power via a conventional drive shaft through to the rear rail axle.
Design Excellence Awards!! RailPro’s DSDS™ System was recognised with an SABS Design Excellence Award in 2009.
Key Design Advantages
? A large “rigid” road-going truck, with retractable rail wheels, can run on rails, as it would on a road
? Direct drive through truck’s gearbox to the rear rail wheels
? Active use of truck’s existing suspension; Front suspension provided by RUBAX axle while on rail
? Speed is dramatically increased
? The truck’s braking system is used to slow the vehicle
? Lightweight – the rail gear mass is approximately 65% lighter than existing products
? Ground clearance almost double that of competitors
? Rail gear is fully “deployable” and “retractable” in minutes
? Simple, efficient driveshaft system – direct drive through truck’s gearbox to the rear rail wheels
? Active use of truck’s existing suspension while on rail
? The truck’s braking system is used to slow the vehicle
? Excellent ground clearance & departure angles
? Reliable, requiring low maintenance
? Bolt-on system, requiring minimal chassis modification
? Solid axles front and rear
? Can be offered to suit a wide range of rail gauges
? Minimal modification required to standard chassis
? Overall length of vehicle with rail gear raised is virtually unchanged from standard
Features of the Elevating Work Platform
? Electro-mechanical stability control mechanism (i.e. requires no PLC)
? Able to function as both “cherry picker” and crane
? Full proportional control from basket or deck controls
? Reliable, requiring low maintenance
? Side-shift capability incorporating counterweight in base
? Rotation capability +/- 180 degrees
? Able to load tools & personnel at ground level
? Incorporates use of outriggers while in crane mode only
? Comprehensive suite of safety interlocks
? Fully compliant with ISO 16368-2010
