The floor panel includes: a front floor panel and a rear floor panel that cover an upper surface and a rear surface of the fuel tank. and that have a roof section located above height positions of flanges of the side members. The rear floor panel has: a bottom surface located below the height positions of the flanges of the side members; rear vertical wall sections raised upward from both of left and right sides of the bottom surface; and rear flat sections folded to the left and the right at upper ends of the rear left and right vertical wall sections and joined to upper surface sides of the flanges on a vehicle inner side of the pair of side members.

The mobile foundation for tower cranes and fast-erecting cranes comprises at least two floor elements made from metal, which may be releasably connected to one another, in particular screwed to one another, wherein the floor elements have anchoring devices for a crane tower. Transportable, reusable ballast weights may be supported on at least one support surface of the foundation. There is provided a passage element having uprights and/or side walls, wherein the uprights or side walls, respectively, have a height of at least 2.1 m, preferably of at least 2.3 m, wherein the passage element may be releasably connected to the floor elements, in particular screwed thereto.

Presented are battery assemblies with integrated fuel tanks, methods for making/using such battery assemblies, and fuel cell electric vehicles having rechargeable traction battery packs with integrated fiber-composite hydrogen fuel tanks. A rechargeable energy storage system (RESS) assembly includes a battery pack housing with an internal battery module compartment located between two tank mounting cavities. Each mounting cavity is recessed into a respective lateral side of the battery pack housing. Multiple rechargeable battery modules are electrically interconnected with one another and mounted inside the battery module compartment. Each battery module contains multiple battery cells, such as a stack of series-connected lithium-ion pouch cells. A fuel tank is mounted in each of the tank mounting cavities on the lateral sides of the battery pack housing. Each fuel tank, which may be fabricated from a carbon fiber reinforced polymer, stores and selectively dispenses a fuel, such as a hydrogen-rich, compressed gas fuel.
