FAQs 6

Can energy storage systems be installed in RTG cranes?

The last 20 years researchers proposed the installation of different energy storage systems, such as BESS, SCESs and combinations of BESSs with SCESs, FESS, in RTG cranes. In this work an evaluation in energy efficiency and purchase cost for these systems is performed and analyzed.

How much energy does a crane use?

Quantifying the energy demand, we see that the crane is active about 50% of the entire operation time of which about 62% of the energy is used by the hoist motors, 31% is used by the gantry motors and about 10% is for the trolley and losses . For the remaining time the crane is in idle mode with the DEG switched on consuming diesel fuel.

How does a RTG crane work?

During the lifting of a container by a conventional RTG crane, the DΕG provides power and energy required by the hoist motors. During the lowering of a container, the hoist motor acts as a generator by creating regenerative braking energy. This energy is dissipated as heat to braking resistors reducing the efficiency of the RTG crane.

How sustainable are RTG cranes compared to conventional cranes?

In Table 6 we present the economical sustainability of the different systems compared to the conventional type RTG crane, i.e., without ESS. We assumed that for the conventional RTG the typical consumption is 2.40 L/move or 1.20 L/TEU, considering that 20 moves/h equals 40 twenty-foot equivalent unit (TEU)/h .

Does a rubber tyred gantry crane save energy?

Net energy savings in Rubber Tyred Gantry cranes equipped with an active front end. EEEIC 2016 - International Conference on Environment and Electrical Engineering, Institute of Electrical and Electronics Engineers Inc.; 2016.

How much power does a RTG crane use?

In RTG cranes the power peak is at 292 kW when the container is accelerated upwards while the power demand drops at 225 kW to maintain a constant speed of 26 m/min. During deceleration the peak power reaches 170 kW when the hoist motor lowers the container. For this single move the average power demand is 61.6 kW.
