LOWER FUEL CONSUMPTION
The E-One2 provides fuel savings of up to 60% compared to
conventional RT Gs by combining our Variable Speed Generator,
system and the optional hybrid package. Combined with the
array of energy-saving features found on the E-One+, this puts
an unbeatable cost-saving combination at your service.
VARIABLE SPEED GENERATOR (VSG)
With its new optional Variable Speed Generator (VSG), the
E-One2 provides considerably better fuel economy, as the
engine runs at a lower RPM level when idling. The system
automatically optimises the engine’s RPM according to
power needed, resulting in lower fuel consumption. Auxiliary
loads, such as air conditioning and working lights, are
powered continuously. When compared to conventional RT
Gs consuming around 21 litres per hour, CO 2 emissions are
reduced by 100.000 kg/year (assuming 4.000 operating hours/
year). Other emissions are also reduced accordingly.
Fuel savings of up to 45%.
HYBRID PACKAGE
The E-One2 is modularly designed and ready for Hybrid Package
adaptation. It can be equipped with an energy optimized
Variable Speed Generator set combined with an energy storage
system. Regenerative energy is stored in the energy storage
system and is used again in hoisting. Energy consumption,
emissions, noise and operating costs are reduced even further.
Fuel savings up to 60%.
The Kalmar SmartPower RT G minimizes fuel consumption even
further. Requiring merely 9 liter of fuel per hour in a typical
configuration the SmartPower RT G saves up to 10 liters per
hour in comparison to conventional RT Gs. Additionally, based
on an assumed 4000 operating hours per year, it will save up
100.000kg of CO 2 emission per year (per crane)!
BALANCED PERFORMANCE
The SmartPower RT G provides a better balance between
productivity and cost efficiency. The new crane is equipped
with an intelligent power management system, which ensures
the most economical engine RPM is used at all times during
operation and controls speeds and accelerations to reduce the
peak power requirement. The Kalmar SmartPower RT G has been
designed for typical applications handling between 9 and 18
containers per hour, where it provides the perfect balance
between productivity and cost efficiency.
The RT G has a significantly smaller diesel engine compared
to conventional RT G’s. These technological innovations
lead to a fuel consumption of only 9 liters per operational
hour in typical RT G applications, which is the lowest fuel
consumption without energy storage in the industry. Typical
RT G engines range from 450 to 550 kW. Conventional RT Gs
consume approximately 18 to 21 liters per hour while the
more modern E-One2 RT Gs with a large engine consume
between 11 to 15 liters. The SmartPower RT G features a
much smaller engine (250 to 280 kW), resulting in the much
lower fuel consumption.
