Gantry crane vehicles and methods for photovoltaic arrays

A gantry crane vehicle for performing one or more tasks in a photovoltaic array, the vehicle comprising:

• one or more base plates;
• one or more tracks above the one or more base plates;
• one or more gantry assemblies configured to slide along the one or more tracks;
• one or more first support trusses attached to the one or more base plates and substantially perpendicular to the one or more base plates;
• one or more second support trusses, at least one of the one or more second support trusses being connected to at least one of the one or more first support trusses;
• one or more third support trusses, each of the one or more third support trusses being connected to at least one of the one or more first support trusses or being connected to at least one of the one or more second support trusses;
• and
• one or more storage cabinets located on the one or more base plates, the one or more storage cabinets including one or more top surfaces and one or more side surfaces, the one or more top surfaces being located below the one or more tracks;
• wherein:
• each of the one or more gantry assemblies includes a lift component and one or more frame components attached to the lift component;
• and
• the lift component is configured to move the one or more frame components from a first position above one or more planes corresponding to the one or more base plates to a second position below the one or more planes corresponding to the one or more base plates;
• wherein:
• each of the one or more third support trusses includes a first side component, a second side component, and multiple middle components;
• each of the multiple middle components is sandwiched between and in contact with the first side component and the second side component;
• and
• the multiple middle components are separated from each other by one or more slots.
