A high-pressure hydrogen tank includes a metal circular cylinder configured to store high-pressure hydrogen therein, a cap part configured to cover each of opposite end portions of the metal circular cylinder, an outer cylinder surrounding an outer periphery of a circular-cylindrical portion of the metal circular cylinder, and a fastening part configured to fix the cap part to the outer cylinder.

A hydrogen fuel cell forklift truck with a distributed architecture includes a frame, and, a hydrogen storage system, a fuel cell, a cooling system and an energy storage system arranged on the frame, and the fuel cell is connected with the hydrogen storage system and the energy storage system for charging the energy storage system and providing kinetic energy; the hydrogen storage system is located outside the fuel cell and exposed to the frame for supplying hydrogen to the fuel cell; the cooling system is located outside the fuel cell and connected to the fuel cell for cooling the fuel cell; the energy storage system is located outside the fuel cell and connected to the fuel cell for recovering braking energy and providing kinetic energy together with the fuel cell.

A rotary telescopic boom lift, which comprises at least one self-propelled machine, which can move over ground and supports in an upper region a rotating assembly, associated with the machine by way of a rotary coupling element. The assembly comprises at least one turret and an operating boom, which is articulated to the turret with a first end thereof.

The boom lift comprises elements for supplying electrical power, at least for the movement of the machine, the rotation of the assembly and the actuation of the boom. Such elements comprise at least one first battery which is integrally supported by the machine and is arranged substantially below the element, and at least one second battery which is supported by the assembly and can rotate with respect to the machine integrally with this assembly. Such second battery is arranged substantially above the element.

An industrial truck comprises a support having a plurality of receptacles and a hydraulic fluid tank comprising a plurality of feet engaged with a bottom surface of the hydraulic fluid tank. Each of the plurality of feet is configured to be received by one of the plurality of receptacles.

A modular assembly for a fuel-cell vehicle is configured to connect to a bracket arranged along a longitudinal frame of the vehicle. The modular frame can include one or more components for powering the vehicle, including one or more of a fuel cell, a battery, a battery cooling system, and hydrogen storage tanks. The modular assembly can communicate with the fuel-cell vehicle through standard integration components regardless of the particular components in the modular assembly. The modular assembly can be readily removed from the fuel-cell vehicle and replaced with a different modular assembly containing different components.

A hydraulic module is provided for a materials-handling vehicle. The hydraulic module can include a mounting frame configured to mechanically connect to a frame of the vehicle but isolate the vehicle frame from vibrations occurring in the power pack. The mounting frame supports the primary components of a hydraulic energy recovery system, including, for instance, a hydraulic tank, a hydraulic pump, and an electric motor. The hydraulic energy recovery system components can be secured to the mounting frame before the mounting frame is connected to the vehicle frame. Standardized integration components such as cables, tubes, and wiring can be used to connect the module to the electrical and hydraulic systems of the vehicle. A fluid level sensor and indicator can be provided to indicate the fluid level of the hydraulic tank. Check valves can be mounted to adapter blocks to ensure low delta pressure during operation.

The present disclosure relates to an apparatus for fixing a pressure vessel, the apparatus including: a frame part disposed separably from a subject and configured to support a pressure vessel; and a lifting device configured to selectively raise or lower the frame part relative to the subject, thereby facilitating a process of replacing the pressure vessel.

Commonly available industrial vehicles may be constructed with a frame originally designed for a particular fuel source where such a frame is used to construct an industrial vehicle that uses a different fuel source with a different fuel storage compared to the industrial vehicle for which such a frame was originally intended. Such a truck powered by a different fuel source typically includes an empty space that was originally intended to house the original fuel, and such empty space may be used to increase the hydraulic storage capacity for such a truck.

The invention concerns a fluid container (1) for a motor vehicle, in particular a fuel tank. The fluid container (1) comprises at least one clamping strap (3) surrounding this to hold it at predefined fixing points of the bodywork (4) of a motor vehicle. The fluid container (1) according to the invention is characterized in that the clamping strap (3) is premounted captively on the fluid container (1) without additional fixing means.
