A storage lift has two columns, and a hoisting shaft for a conveyor unit ( ) movable up and down between the two columns. A light grille ( ) is arranged in the storage lift on the end of the conveyor unit ( ) facing a charging and discharging opening ( ). The light grille provides measurement of the height of the goods on the storage lift, and also acts as a safety element. Safety aprons ( ) are mounted on the top edge of the charging and discharging opening ( ) and on the lower front edge of the conveyor unit ( ) for compensating for shifting delays during braking of the conveyor unit ( ).

Goods lift

In the case of a storage rack, in each case a plurality of load carriers (9, 10) are assigned to the storage locations, the load carriers forming a load-carrier stack. The load-carrier stacks can be transferred from the respective storage locations, with the aid of a vertically displaceable storage and retrieval apparatus (6), to a charging and removal location (4) of the rack. In this arrangement, the storage and retrieval apparatus is provided with a lifting mechanism which exhibits pivot levers (24), arranged in pairs to the sides of the load carriers (9, 10), and which makes it possible to separate the load carriers (9, 10) from one another in the region of the charging and removal location (4) by raising up the respectively top load carrier (10) from a load-carrier stack comprising two load carriers. In order to be able to remove storage items from the bottom load carrier (9), it is only the latter which is transferred into the region of the charging and removal location (4), whereas, for removal from the top load carrier (10), the entire load-carrier stack carries out a horizontal movement.

Storage rack

In a high-rise shelving having two shelving columns (2, 3) and a vertical conveyor (6) disposed therebetween, the bases (9) of shelf-racks (7), which shelf-racks can be transferred by the vertical conveyor (6) into the compartments of the shelving columns (2, 3), are provided with respectively at least one recess (11, 12), through which, in the region of the feed or removal opening (13) of the shelving, parts (20) of an auxiliary conveyor (21) can be brought into engagement with objects (22) deposited on the shelf-racks (7) so as to load or unload these objects.

High-rise shelving

The present invention provides a circulating rack having an electric drive which can be pivoted, to a limited degree, in opposed directions dependent upon the transmitted torque of the electric drive. The drive is mounted on a pivotal rocker element which is displaced against the force of two counteracting elastically deformable abutments. A torque transmitted by the electric drive to overcome non-uniform loading of the circulating rack system causes the pivotal rocker to be displaced in either a clockwise or counterclockwise direction. A displacement measuring sensor measures the extent of pivotal movement of the rocker to provide an indication of the non-uniform loading condition so that corrective action may be taken. If the rocker is pivoted beyond a predetermined range, as for example that caused by a severe overloading condition, the displacement measuring sensor will cause the electric drive to turn off and prevent further circulation of the system until the overload has been corrected.
