By using an E-Deutz diesel engine and driveline to power a generator and store energy in a battery pack, the Manitou telehandler above can down-size from a 3.6 litre/74.5kW engine to a 2.2 litre/54kW engine and tap 20kW from the batteries and generator to make up the difference.
In the past, an engine manufacturer’s responsibility stopped at the flywheel. Today, an increasing number of engine OEMs are paying as much attention to the drivetrain as they are to the engine itself. And this includes, in many cases, electrified and hybrid drive trains.
The fully electric Manitou MT 1135 telehandler has a 360-volt vehicle power supply and an 80-horsepower (60 kilowatt) electric motor with a 30-kilowatt-hour battery, all driven by a Deutz TCD 3.6 litre engine. For the hybrid E-Deutz drive, the company was able to replace the 3.6-litre engine with a Deutz TCD 2.2-litre engine which generates 55kW (73hp) boosted by a 20kW (26hp) electric motor and 48-volt system in a Manitou MT 1335 telehandler
The hybrid Liebherr TL 432-7 telehandler also downsized from a 3.6 to a 2.2L Deutz engine, while maintaining the same aggregate horsepower combining mechanical and electrical output. In both cases the hybrid machines can be powered mechanically or on nothing but electrical power by storing the energy in a 10-kilowatt-hour battery. Deutz says a 15 per cent fuel savings can be achieved depending on load cycle and application.
