Storage System with Mechanical Safety Provision

Storage system, comprising a mobile base for supporting at least one cabinet, that is:

• movable and in particular rollable with respect to a support surface, provided with
• a drive mechanism that extends via a transmission between
• at least a first engagement point for receiving a driving force or torque, to
• at least a second engagement point for exerting a driving force or torque on the surface,
• wherein the cabinet is provided with:
• an emergency braking facility, with at least:
• one activating member, which emergency braking facility is
• adapted to stop the cabinet to a standstill with a limited braking torque or with a limited braking force when the activating member is enabled, wherein the emergency braking facility is adapted to block the drive mechanism at a blocking point located between the first and the second engagement point, wherein a first force or torque limiter, such as a slip clutch, is present between the blocking point and the second engagement point,
• wherein:
• the drive mechanism comprises a manual operating element, such as a wheel or a handle at the first engagement point for manually driving the shelving unit further comprises a second force or torque limiter, such as a slip clutch arranged in said transmission for manually driving the shelving unit;
• wherein:
• the second force or torque limiter, such as a slip clutch in the transmission for manually driving the shelving unit, has a threshold torque above which it starts limiting or slipping, that is lower than a threshold torque of the first force or torque limiter, such as a slip clutch, of the emergency braking facility.
