Abstract: A driving mechanism having a braking system, for use on a storage unit movable about guiding tracks, The driving mechanism comprises a frame rotatably carrying at least one driving wheel, which in turn rollably engages a floor-embedded guiding track, A toothed wheel rotatably carried by the frame is operatively connected to the driving wheel and rotates in synchronism therewith, and defines at least one first interlock member, The driving mechanism also comprises a gravity-biased second braking member defining at least one second interlock member, said second braking member movably mounted to the frame so as to be movable between a standby position in which the second interlock member clears the first interlock member, and a braking position in which the second interlock member is interlocked with the first interlock member to block rotation of the rotary first braking member and thus of the driving wheel, The second braking member is biased under the action of gravity towards the braking position when it is

Abstract: A driving mechanism having a braking system, for use on a storage unit movable about guiding tracks. The driving mechanism comprises a frame rotatably carrying at least one driving wheel, which in turn rollably engages a floor-embedded guiding track. A toothed wheel rotatably carried by the frame is operatively connected to the driving wheel and rotates in synchronism therewith, and defines at least one first interlock member. The driving mechanism also comprises a gravity-biased second braking member defining at least one second interlock member, said second braking member movably mounted to the frame so as to be movable between a standby position in which the second interlock member clears the first interlock member, and a braking position in which the second interlock member is interlocked with the first interlock member to block rotation of the rotary first braking member and thus of the driving wheel.

Abstract: The shelving system has a number of electrically powered shelf units movable over ground, each shelf unit including an electronic circuit controlling the displacement of the shelf unit, a power cord connected to the shelf unit with of a power terminal rod, for feeding power to the shelf unit, and a network cable connected to the shelf unit with a network terminal rod, for allowing information to be exchanged with the electronic circuit. The shelving system further has a wire track that may be embedded in the ground, the wire track including an elongated main body having a hollow power wire channel housing the power cord and having an elongated opening allowing access to the power wire channel and forming an elongated power raceway allowing the power terminal rod to extend from the power wire channel to the shelf unit through the power raceway and to slide along the power raceway.

Abstract: The hybrid shelving unit comprises first and second spaced-apart end frame portions, an intermediate frame portion located spacedly between the first and second end frame portions, a first spacer element attached to the first end frame portion and linking the first end frame portion and the intermediate frame portion, a second spacer element different from the first spacer element, attached to the second end frame portion and linking the second end frame portion and the intermediate frame portion, first brackets attaching the first spacer element to the intermediate frame portion, second brackets different from the first brackets and attaching the second spacer element to the intermediate frame portion, first shelves located and supported between the first end frame portion and the intermediate frame portion, and second shelves located and supported between the second end frame portion and the intermediate frame portion.
