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
