XCMG’s Hybrid European AT
Chinese crane manufacturer XCMG unveiled a 60 tonne hybrid All
Terrain crane at Bauma based on the company’s existing XCA60 E. The hybrid
XCA60 EV model was designed specifically for the European market with the help
of Dutch crane customers and will soon be available for sale.
The crane’s hydraulic system is powered by a massive 170kW
electrical motor, with three potential operating modes: the diesel engine which
is equipped with a generator, or the crane can be connected to a 32 or 64 amp
AC power outlet for continuous emission free operation with performance
matching or exceeding the diesel, and finally the crane can also operate
electrically without plugging in, thanks to its built-in 115kWh high capacity
lithium ion battery pack, which is apparently good for up to four hours of
crane operation. The batteries can also be recharged from the AC outlet or the
diesel engine, with excess power topping up the battery pack. This includes
recharging while travelling.
The three axle carrier has all wheel steer as standard along with
front and rear axle drive, although all wheel drive is available. The crane has
an independent suspension system, which looks quite similar to that used on the
Grove GMKs. The ‘Dual-Power’ drive concept is a type of hybrid system, which
combines power from both the diesel and the electric motor, for both road and
off road travel, with the electrical motor intervening intelligently to
maximise the energy utilisation. According to XCMG the combination provides up
to 400kW of power and has been proven to reduce fuel consumption by around 40
percent. In addition to everything else the crane is equipped with regenerative
braking and coasting allowing it to generate electricity to top up the
batteries.
Thinking on the needs of the European market and focusing on the
growing demands for the use of renewable resources and mainly on the reduction
of emissions, which XCMG believes is a trend in large European cities. This
crane was developed with the support from companies in the Netherlands, who
gave XCMG many important inputs in the design phase.
