SIMOCRANE Advanced Technology
SIMOCRANE ECO Technology
■
Overview
Crane configurations with diesel generators in conventional con-
stant-speed mode with their high fuel consumption and unnec-
essary environmental pollution are a thing of the past.
With SIMOCRANE ECO Technology, the diesel generator runs in
tune with the energy requirements of crane operation at optimum
speed without any reduction in performance. Operation of the
diesel generator with load-dependent speed control results in a
reduction in fuel consumption and emissions.
With SIMOCRANE ECO Technology as the basis, Siemens has
established the trend for fuel saving and emission reduction for
cranes with diesel generators and therefore sets the standard to-
day.

Benefits
Energy and cost saving
The most important, reliable and low-cost source of future en-
ergy is energy saving. Depending on the configuration of the
drive system, the crane type, plant layout and operating condi-
tions in the terminal, the new SIMOCRANE ECO Technology
supports significant savings in actual fuel consumption of
the crane. The ECO configuration with its specially developed
energy management software is designed such that all de-
mands are satisfied with regard to operating cranes with diesel
generators. Through ECO Technology, energy flow within the
system can be optimized.
Experience gained from the operations of numerous terminals
worldwide demonstrates that terminal operators can save con-
siderable quantities of fuel by implementing SIMOCRANE ECO
Technology with the same operating conditions, the same struc-
ture and throughput. With integrated energy storage, even
higher savings are possible. Investments in the ECO system are
soon amortized by these savings. Furthermore, the considerable
reduction in fuel consumption reduces CO
2
emissions by the
same amount.
Flexible configurations
Siemens has bundled its expertise in a software package that
utilizes the standard industrial drives platform SINAMICS and
which can therefore be individually adapted to the situation and
requirements of the crane.
Benefits of SIMOCRANE ECO Technology
•
Savings in operating costs due to reduced fuel consumption
•
Reduction in the CO
2
balance of the crane due to reduced fuel
consumption
•
Reduction in the noise emission due to variable load-
dependent motor speeds
•
Smaller spare parts inventories due to the use of standard
Siemens components
•
Lower maintenance costs
•
Easier modernization of existing cranes
■
Application
SIMOCRANE ECO Technology is not only a powerpack system
for rubber tired gantry (RTG) cranes, but also for all electrically
operated cranes with diesel generators, such as straddle carri-
ers, diesel-electric container bridges, mobile and floating
cranes as well as driverless transport systems (AGV and
1-over-1 straddles).
The core component of power management is an easily oper-
ated software package that can be integrated into SIMOCRANE
Basic Technology.
The crane configuration comprises SINAMICS and SIMATIC
standard products. With this new concept, ECO configurations
can be aligned with environmental protection goals with opti-
mum results with regard to cost savings, performance and via-
bility.
■
Design
SIMOCRANE ECO Technology is power management software.
It is designed for use in cranes and vehicles that are operated
with an engine and an AC generator (diesel generator). These
components are used to generate the energy for performing
movements and for infeed of auxiliary energy.
SIMOCRANE ECO Technology can be easily implemented with
SIMOCRANE Basic Technology. In this case, special ECO
blocks are simply linked to SIMOCRANE Basic Technology
blocks. The SIMOCRANE ECO Technology can also be used
without the SIMOCRANE Basic Technology.
ECO Technology varies the speed of the engine in accordance
with the actual energy required for the purpose of optimizing the
fuel consumption. As compared with cranes operating with con-
stant speed engines, or cranes with 2 speeds, fuel consumption
is reduced in every operating mode.
