The Project Consists of the Acquisition of the E-RTG that we have introduced
consists of the improvement and conversion of the traditional machinery with a
fossil fuel, to a machine, for the movement of containers, more
respectful with the environment “E-RTG” by providing a system capable of
contact the power grid.

The new system installed on the machine is fed from the electrical network through
an installation of electrical conductors (catenary type) located in the

The system installed thanks to its “drive in” system allows connection / disconnection
of the machine automatically when entering to work in the blocks of containers.
The diesel generator of the machine has not been disassembled to allow
movements between blocks (see attached electrical diagram).

The drive in unit has been installed next to the diesel generator under the portal beam.

These couplings / decouples are monitored and protected by a series of control circuits.
security control and sensors. Activation of movement units
horizontal, vertical and carriage are controlled by independent electric motors.
All processes are controlled by a PLC.

This new control installation is installed inside a refrigerated cabinet
made of stainless steel, accessible next to the electrical room.

These machines also have a diesel engine of the fuel saver type, which allows
the reduction of the rpm automatically when the machine is idle, when
does not work in electrical mode, exclusive use outside the storage area,
approximately 10% of the operating time.

Likewise, the traditional technology luminaires have been replaced by a
LED type with automatic shutdown.

This achieves an estimated saving of up to 30%.

With the following Results:
Energy consumed before and after the action (tep / year)

  • Energy consumed before the action = 371.10 tep / year

Final energy savings (tep / year) and primary (tep / year) 1 and equivalent in euros

  • Final energy savings = 269.60 tep / year
  • Primary energy savings = 177,51 tep/año
  • Economic savings = 122.883,09 €

Reduction of CO2 emissions associated with the proposals.

  • Reduction of associated CO2 emissions = 392,16 tCO2/year
