Service vehicle

A service vehicle for movement on a rail system comprising a first set of parallel rails arranged in a horizontal plane and extending in a first direction and a second set of parallel rails arranged in the horizontal plane and extending in a second direction which is orthogonal to the first direction, wherein the first set of parallel rails and the second set of parallel rails form a grid pattern in the horizontal plane comprising a plurality of adjacent grid cells,

• the service vehicle comprising:
• a chassis and an upper portion mounted on top of the chassis, wherein the service vehicle is divided into a first part relative to a horizontal extent of the upper portion and a second part relative to the horizontal extent of the upper portion, wherein the first part is a container handling vehicle part including one or more components configured for mechanically interacting with a container handling vehicle to be serviced, the container handling vehicle part configured for storing the container handling vehicle operating on the rail system in a loaded position, and wherein the second part is a cab-area configured to contain one or more persons;
• wheels for allowing movement of the service vehicle along the rail system during operation,
• a displacement mechanism, and
• a hoist arrangement connected to the displacement mechanism and configured to be releasably fixed to the container handling vehicle,
• wherein the displacement mechanism and the hoist arrangement are configured for moving the container handling vehicle between an operational position on the rail system and the loaded position within the container handling vehicle part.
