LRV Vehicle Design

Adoption of the LRV vehicle design will result in a Light Rail Vehicle with energy consumption, maintenance and environmental advantages when compared with currently available products. Such a design will cost considerably less to build due to use of technology transfer volume produced components and less to buy as a result of increased competition through licensing arrangements.

LRV Vehicle Design Key Aspects

SERVICEABILITY AND LOW COST OF OWNERSHIP

Individually replaceable wheels on ‘inside bearing’ axles.
Maintenance-free body mounted motors
Driveline, air and vehicle electrical components common with road haulage / P.S.V. industries.
Traction and power control electronics use proven, mass-produced industrial motors, inverters, joysticks etc..
Long life corrosion free “Cromweld” body structure
Built in test equipment (B.I.T.E.) for electrical fault analysis

LRV Vehicle Design Key Aspects
