at least one mounting space between the top surface and the bottom surface for receiving at least one electric component; and

at least one liquid cooling unit, the at least one liquid cooling unit comprising:

at least one pump device for circulating a cooling agent;

at least one heat exchanger for cooling the cooling agent;

at least one cooling agent circulation flow channel connectable to the at least one electric component mounted inside the at least one mounting space;

at least one control element for controlling the at least one liquid cooling unit; and

a cooling unit frame for fastening the at least one liquid cooling unit to the service platform or to an upper frame of the container handling carrier.

2. The service platform as claimed in claim 1 , wherein:

the bottom surface of the service platform is provided with a plurality of through openings for improving cooling of the at least one mounting space.

3. The service platform as claimed in claim 1 , wherein:

the top surface of the service platform comprises a grating and below the grating is a solid cover layer for protecting the at least one mounting space from falling impurities and moisture.

4. The service platform as claimed in claim 1 , wherein: the top surface of the service platform comprises openable lids configured to allow access to the at least one mounting space.

5. The service platform as claimed in claim 1 , wherein:

a vertical height of the service platform is less than 500 mm.

6. The service platform as claimed in claim 1 , wherein: one single longitudinal side of the service platform opposing an electrical cabinet is provided with at least one safety rail on an outer side of the top surface of the service platform.

7. The service platform as claimed in claim 1 , wherein:

the at least one mounting space comprises at least five mounting spaces.

8. The service platform as claimed in claim 1 , wherein: the service platform comprises a plurality of electrical drive control elements of the at least one electric component installed inside the at least one mounting space.

9. A container handling carrier for moving containers, the container handling carrier comprises:

two lower frame parts spaced at a track distance from each other, the two lower frame parts being provided with a plurality of wheels and a plurality of drive units for moving and steering the container handling carrier;

four gantry supports which are supported on the two lower frame parts, the four gantry supports are spaced apart from one another and extend parallel to one another in a vertical direction;

an upper frame which connects the four gantry supports to one another at upper ends of the four gantry supports;

at least one service platform arranged between two opposing pairs of the four gantry supports or between opposing parts of the upper frame;

a lifting device for lifting the containers, which the lifting device is supported by the upper frame;

and wherein the at least one service platform comprises:

a top surface and a bottom surface, the top surface configured to permit maintenance personnel to move;

at least one mounting space between the top surface and the bottom surface for receiving at least one electric component; and

at least one liquid cooling unit, the at least one liquid cooling unit comprising:

at least one pumping device for circulating a cooling agent;

at least one heat exchanger for cooling the cooling agent;

at least one cooling agent circulation flow channel connectable to the at least one electric component mounted inside the at least one mounting space;

at least one control element for controlling the at least one liquid cooling unit; and

a cooling unit frame for fastening the at least one liquid cooling unit to the at least one service platform or to the upper frame of the container handling carrier.

10. The container handling carrier as claimed in claim 9 , wherein:

the container handling carrier further comprises at least one electric cabinet mounted in connection with the upper frame;

each of the at least one electric cabinet comprise openable doors; and

the at least one service platform is located adjacent to the at least one electric cabinet and is on a side of the openable doors of the at least one electric cabinet thereby allowing access to the at least one electric cabinet by the maintenance personnel.

11. The container handling carrier as claimed in claim 9 further comprising electrical drive motors of the drive units which are controlled by means of frequency converters of the at least one electric component; and the frequency converters are mounted inside the at least one mounting space of the at least one service platform.
