Hydraulic system for a vehicle or a container, and vehicle or container having such a hydraulic system

A hydraulic system for supporting a vehicle or a container on a substrate, the hydraulic system comprising:

• at least two supporting cylinders for extending ground supports;
• at least two hydraulic main lines;
• at least two hydraulic pumps, each being connected to one of the two hydraulic main lines;
• at least one of the two supporting cylinders being associated with a first of the two hydraulic main lines;
• at least one of the two supporting cylinders being associated with a second of the two hydraulic main lines;
• a main valve for connecting or disconnecting the first and second hydraulic main lines to one another or from one another, respectively;
• at least one hydraulic motor or a further working cylinder;
• the at least one hydraulic motor or the further working cylinder is configured for controlling movement of an extendable space of the vehicle or the container, an interior of the vehicle or the container being able to be enlarged thereby;
• or
• the at least one hydraulic motor or the further working cylinder is configured for controlling a closing element of a storage space or an interior of the vehicle or the container;
• or
• the at least one hydraulic motor or the further working cylinder is configured for controlling a lifting platform provided on the vehicle or on the container;
• or
• the at least one hydraulic motor or the further working cylinder is configured for controlling an entry system;
• or
• the at least one hydraulic motor is configured for driving a movement system for moving the vehicle.

A vehicle comprising:

• at least two extendable ground supports;
• and
• a hydraulic system for supporting the vehicle and extending and retracting the ground supports, the hydraulic system comprising:
• at least two supporting cylinders for extending the respective ground supports;
• at least two hydraulic main lines;
• at least two hydraulic pumps each being connected to one of the two hydraulic main lines;
• a first electric motor connected to one of the two hydraulic pumps;
• a second electric motor connected to another of the two hydraulic pumps;
• at least a first one of the two supporting cylinders being connected for fluid communication with a first of the two hydraulic main lines such that the first one of the two supporting cylinders is supplied with fluid by the first hydraulic main line;
• at least a second one of the two supporting cylinders being connected for fluid communication with a second of the two hydraulic main lines such that the second one of the two supporting cylinders is supplied with fluid by the second hydraulic main line;
• and
• a switchable main valve disposed to selectively fluidly connect or disconnect the first and second hydraulic main lines to one another or from one another, respectively.
