    BE2018 / 5938
    Detailed description of some embodiments
    Figures 1 and 2 show a portal carrier 1 as an example of a container-handling carrier. The revealed solution can also be used in shuttle carriers. The main difference between the portal carrier and the shuttle carrier is that the shuttle carrier is only designed for transporting containers, while the portal carrier is designed for transporting and stacking the containers. Basic structures of the portal carriers and shuttle carriers are the same.
    The carrier 1 comprises two lower frame portions 2a, 2b which are spatially spaced apart from each other. The frame parts 2a, 2b are provided with wheels 3 and drive units 4 for moving and controlling the carrier 1. The drive units 4 can comprise electric motors 4a. The number of wheels 3 can be 2 - 4 per each frame part 2a, 2b, depending on the capacity of the carrier 1, and the wheels 3 can be steered. The carrier 1 further comprises four portal supports 5a - 5d which are supported on the lower frame parts 2a, 2b. The gantry supports 5a - 5d are spatially spaced apart and extend parallel to each other in the vertical direction. At the upper ends of the portal supports 5a - 5d there is an upper frame 6 which connects the four portal supports with each other. The upper frame 6 can comprise four horizontal frame bars 7a - 7d. The frame beams 7a - 7d can lie on the same horizontal plane. Between two opposite portal supports 5a - 5d or between opposite frame beams 7a - 7d of the upper frame 6 there are one or more service platforms 8 that can serve as bridge-shaped elements. The service platforms 8 can be arranged in a direction of travel A of the carrier 1. However, the platform 8 can only be arranged between frame beams which are located in
    BE2018 / 5938 are located in the direction of travel A, wherein the direction of the platform 8 is transverse to the direction of travel A. The platform 8 may be arranged along distribution boxes 9 located at the upper part of the frame. The platform 8 and the distribution boxes 9 comprise spaces for electrical devices and components of the carrier 1. The platform 8 can also comprise safety rails 10.
    On the upper part of the carrier 1 there can also be a control cabin 11 which is provided with manual control and control means for an operator, or alternatively the carrier 1 can be controlled remotely or completely autonomously, so that there is no control cabin 11 is necessary. Figure 2 shows that the control cabin 11 may be located in the center of the top frame 6, but typically it is located asymmetrically to the right. The carrier 1 further comprises a lifting device 12 for lifting containers C. The lifting device 12 is supported on the upper frame 6 by means of monitoring cables 13, chains or corresponding flexible transfer elements. As can be seen, the carrier 1 can be positioned above the containers C so that the lower frame portions 2a, 2b and the gantry supports 5a, 5b and 5c, 5d are on opposite sides of the containers C. The lifting device 12 may comprise a spreader 14 provided with locking elements configured to be inserted into locking holes located at upper corners of the containers C.
    Figure 3 discloses a service platform 8, which is an elongated bridge-like element with length L, width W and height H. A grid 16 can be present on an upper surface side 15 of the platform 8 to ensure a safe anti-slip surface on which maintenance personnel can move . The platform 8 comprises
    BE2018 / 5938 a frame 18 on which the grid 16 is supported. On a lower surface side 19 of the platform 8 there is a bottom 20 of the frame 18. The bottom 20 of the frame 18 can comprise openings. Between the grid 16 and the bottom surface 20 in one or more mounting spaces 21. In Figure 1, the number of mounting spaces 21 is six, but the number of mounting spaces may, for example, be 1 to 10. Transverse partition walls may be located between the adjacent mounting spaces 21. The grille 16 can be divided into different parts that can serve as covers 22 that can be opened for the mounting spaces 21.
    Figure 3 further discloses that the platform 8 can be provided with a liquid cooling unit 23 through which the mounting spaces 21 and devices arranged therein can be cooled. The liquid cooling unit 23 may comprise a pumping device 24 for circulating coolant, such as water or oil, in coolant channels 25, such as tubes or hoses. The unit 23 also comprises a heat exchanger 26 for cooling the coolant. A fan may be connected to the heat exchanger 26 which is rotated by means of an electric motor 27. The unit may further comprise a frame 28 for attaching the unit to the platform 8 or to any other suitable location on the top frame of the carrier . The unit 23 further comprises control means for controlling the operation of the recorded devices and for controlling fluid circulation of the system. The unit can also be provided with one or more coolant reservoirs or tanks.
    Figure 4 discloses an alternative platform 8 that is not provided with a liquid cooling unit. The platform 8 comprises various adjacent mounting spaces that are covered by removable covers 22.
    BE2018 / 5938
    Figure 5 discloses a platform 8 that includes various adjacent mounting spaces 21 in which electrical components 29 such as frequency converters 30 and other electrical control devices 31 are arranged for controlling electrical drive units such as electric motors. The electrical component 29 may include a switch box 32 for connecting the component 29 to an electrical line 33 comprising one or more electrical control cables and power supply cables. The electrical components 29 can also include coolant ports 34 for coolant supply and removal. Within the electrical component 29, an internal cooling circuit can be present which can be connected to an external cooling system. The platform 8 may comprise an electrical connection element 35 and coolant connection elements 36 for connection of the platform to an electrical system of the carrier and to the cooling system located outside the platform 8.
    Figure 5 also discloses that the covers 22 can be removable elements and can be supported vertically on side walls 37 of a frame of the platform 8. Between the mounting space 21 there can be partition walls 38 whose top surfaces can also provide support for the covers 22. Alternative the covers are not completely removable but are connected to the frame of the platform 8 by means of hinges 39.
    Figure 6 discloses that the platform 8 can be located between distribution boxes 9 and a frame beam 7a of an upper frame 6. As can be seen, the frame beam 7a can be located at a transversal distance from an outer surface side of the carrier. The distribution boxes 9 may comprise doors 40 on the side of the platform 8. In this embodiment, no safety rails are required because the platform is located between the
    BE2018 / 5938 cabinets 9 and the frame beam 7a. A liquid cooling unit 23 is located at one end portion of the platform. When the unit 23 is located on the platform 8, service of the unit 23 is facilitated.
    In Figure 7, the top layout of the top frame 6 differs from that of the previous Figure 6. Now the distribution boxes 9 are located between the frame beam 7a and the platform 8. In other words, the platform is located on an open side of the top frame 6. Another difference with the previous figure is that the liquid cooling unit 23 is not arranged in connection with the platform but is mounted on a frame beam 7d and is located at a distance of the platform 8. Subsequently, the platform 8 can comprise connecting means 35, 36 as disclosed in Figure 5. The operation of the unit 23 can be controlled by means of a control unit CU, which can be configured to control the components of the unit as well as possible control valves and other flow control means.
    Figure 8 discloses that the bottom 20 of the frame 18 of the platform 8 can include various passage openings 41 for improving heat transfer away from the mounting space 21. Figure 8 further discloses that the coolant tube 25 or hose to the bottom 20 of the platform 8 can be connected by means of support elements 42. The same type of support elements can also be used for holding the electrical cables in the platform 8. The covers 22 can be supported vertically by means of suitable support elements 43, such as corner pieces. Furthermore, a fixed covering layer 44 can be present under the grille 16 for protection of the fixing space 21 against falling dirt and water.
