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
