ELECTRIFICATION
Danfoss and Sany extend electrification of
off-highway machines
At Bauma 2022 in Munich, Germany,
Danfoss revealed that its electrified powertrain
system was driving a new electric
crawler crane, the Sany SCE800TB-EV.
This will be Sany's first fully electric volume-model
crawler crane and is available
for batch order in the European market,
where Danfoss states that there is increasing
demand for zero-emission construction
machines.
The Sany SCE800TB-EV is an 80-ton

product management at Scania.
engine earlier in the starting process, so
we don't have to get up to a certain
engine speed before we can start injecting
fuel. "
Reducing operating costs is not only
about reduced fuel consumption and
extending service intervals. Engines that
are easier to service save time and potentially
cost in maintenance programs.
" If you look at our current engine lineup,
we don't have all the service points
on the same side of the engine, " Nilsson
said. " With this new engine, we've tried
to gather them in the same area location-wise
on the engine, to make it easier.
We can service from one side rather
than having service points spread out on
the engine. We are also offering various
options of cartridge filters and spin-on
filters, depending on customers' demands.
So, from that perspective, with a
spin-on filter, in some applications it is
easier to service as well. "
The engines have been designed to
conform to the emissions regulations in
markets with the strictest legislation, effectively
Europe, the United States and
China. This means conformity to EU Stage
5 for power generation and industrial use,
China Phase 4 for industrial applications
and U.S. Tier 4 Final certification level. " All
these engines will be available for nonregulated
markets, where we can really
focus on CO2
optimization and fuel efficiency, "
Nilsson said.

telescopic crane with a maximum lifting
moment of 300 ton-meters and a maximum
boom length of 47 meters (155 ft).
The electric system features a permanent-magnetic
synchronous motor and
an inverter supplied by Danfoss's
Editron division as well as a Danfoss
D1P hydraulic pump.
" We've been a strategic partner of
Sany's for several years, jointly developing
a number of fully electric and hybrid
machines such as a 25-ton truck crane, "
said Chao Wang, head of Editron China
at Danfoss Power Solutions. " Our experience
in off-highway applications and the
high efficiencies offered by our products
are assisting Sany on its electrification
evolution and helping the company's
products reach more parts of the world. "
Victor Yin, business development
manager of Sany's crane division, added:
" We have an excellent relationship
with Danfoss, as it offers the rich experience
and European service system
that we require from our suppliers. The
company's experts also go above and
beyond to meet our needs, such as by
testing the hydraulic system of our new
fully electric crawler crane before installation
to ensure all the components
function well together. "
