• W and E Electric Vehicles and Iveco Ford Special Vehicle Operations have jointly produced the first electrically powered Iveco Ford Cargo.
A prototype, based on the 0609 Cargo chassis, is currently operating at Gatwick Airport as a baggage carrier for British Airways, and the airline has already ordered a further 12 vehicles, equipped with bodywork supplied by J Gardiner and Sons of Edenbridge, Kent.
Shown at the Airport '88 exhibition last week, the sixtonne electric Cargo with a 3.2m wheelbase has a payload of 1,940kg.
The conventional 4.2-litre 66kW Cargo diesel engine is replaced by a 17kW DC electric traction motor — but the radiator matrix and gearbox are retained.
Dual header tanks behind the cab hold coolant and diesel to power the Eberspacher D5W water heater, allowing normal operation of the truck's heating and ventilation system.
The Cargo's conventional four-speed gearbox is retained — normally locked in second gear — to provide an alternative gearing option should the vehicle's type of operation be changed. An automatic-type gear lever provides a choice of direction. A Cableforrn Mk X foot-operated controller is specified to give smooth, precise manoeuvering.
Air pressure for the standard air/hydraulic brake system, operating discs on all wheels, is produced by a compressor, independently driven by an 0.75kW DC motor.
With a top speed of 511un/h the vehicle has a range of between 50 and 65km.
The 60-cell lead acid battery system incorporates an AC/DC converter to reduce voltage levels from 120V to power the standard 12V vehicle electrics. An automatic topping-up system reduces the need for constant attention.
W and E claims the electric Cargo has several benefits for airport use: it is quiet; produces no fumes or oil/fuel spillage; the driveline is designed to give consistent performance Prototype electric Cargo is based on a 0609 chassis, but with a 17kW DC electric motor. in all weather conditions; spares are readily avaialble from Iveco Ford dealers; and all servicing related to the power unit is deleted.
▪ W and E Vehicles says that it can still produce an electric version of the Leyland Daf Roadrunner, although it now no longer appears to be a major priority for the chassis manufacturer. According to Leyland Daf the electric Roadrunner is unlikely to be commercially viable until the advent of Sodium Sulphide batteries.
