  • This invention relates in general to the construction of shelf handling and in particular, to a new and useful shelf handling device having an upstanding-mast formed by spaced apart vertical mast members which are connected at their bottom end to a basket stand of a lift truck which is movable vertically along the masts, the truck also being movable, along with the masts, along a shelf corridor on a defined trackway.
  • Shelf handling devices of the type with which the invention is concerned include an operators stand for the operator so that he can move along the shelves and move upwardly with the lift stand to remove stored material from the shelves or to store it thereon.
  • the lift trucks of the known shelf handling devices are provided as needed with various load carriers, for example, with fork-lifts or telescoping tables which are extendible in transverse directions and which facilitate the placing in and taking out of storage of the various shelf items.
  • the operators entrance to the stand on the lift truck is provided from the front end or if this is not possible due to any existing load carriers, it is located on the side of the lift truck opposite to the lift masts.
  • a shelf handling device which is constructed with a base stand which is movable upwardly and downwardly in respect to a vertical mast and which is of such a sturdy construction, so that the load receiving means, for example the supporting tables, or forks, can be constructed in an optimum manner adequately adapted to the particular storage conditions.
  • the manufacturer of such shelf handling devices may manufacture certain portions of the device as standard elements unchanged in all of the various designs so that they may be manufactured in relatively large quantities. These basic elements are supplemented by independently produced elements of uniform design sized to the variations required. Such changes and additions may be installed subsequently, that is after delivery of the unit.
  • the lift stand is constructed with four columns which are interconnected by longitudinal and transverse beams in order to dispose load receiving means and access doors at the columns.
  • a shelf handling device with such features may be provided with any desired load receiving means in accordance with the customers desires, and access to the stand for the operator may occur from the side which does not carry a load receiving means.
  • the columns on the lift mast side are interconnected by a traverse type longitudinal beam and the columns on the outer side away from the mastare interconnected by an additional longitudinal beam.
  • the longitudinal beams of opposite sides are interconnected by two transverse beams.
  • the transverse beams are preferably made of L-shaped configuration.
  • the transverse beams transmit the vertical forcesand moments acting on the columns farther away from the lift masts to the longitudinal beam arranged between the columns on the lift mast side which also receive the vertical forces and moments and conduct them into aca'ble for moving lift truck vertically on the masts.
  • the longitudinal and transverse beams are, in accordance with a feature of the invention, dimensioned to accommodate the highest moment to be absorbed by the two columns in order to permit the fork lifters, vertically adjustable lift tables, and/or folding tables to be-arranged on both sides of the lift truck at the columns, and to arrange at the longitudinal side of the lift truck standfurtherremoved from the lift mast at one of the two ends of the stand,-an access door permitting access to the stand without removal'of the-loads.
  • FIG. 1 is a front elevational view of a floor traveling shelf handling device having a lift mechanism drive at the bottom thereof shown in a direction crossways to the direction of traveland constructed in accordance with the'invention;
  • FIG. 2 is a section taken'along the 'line IIII of FIG. 1;
  • FIG. 3 is a section taken along theline IIIIII of FIG. 1;
  • FIG. 4 is a view similar to FIG. 1 of another embodiment of shelf loader
  • FIG. 5 is a side elevational view of the device indicated in FIG. 4.
  • FIG. 6 is a top plan view of the device indicated in FIGS. 4 and 5.
  • FIGS. 1 to 3 the invention embodied therein in FIGS. 1 to 3 comprises'a lift truck generally designated 1 which is 'movable vertically upwardly and downwardly in respect to two upright lift masts 2, 2 by the action of a lift mechanism drive (not shown).
  • the lift truck I together with the lift mast are mounted so that they be moved together along the shelf corridors and for this purpose a travel drive 4 located at the bottom of the truck 1 is arranged to drive rollers 50 which run over rails 5.
  • the lift truck 1 includes a basket portion or stand 7 for the operator.
  • the stand carries a treadle 8 and preferably, on the lift mast side, control devices 51 for the operation of the truck.
  • the lift mast side is provided with safety means for the protection of the operator and in particular, the overhead roof 9.
  • the four corners of the stand 7 are formed by columns 10, 11, 12 and 13.
  • the two columns 10 and 11 on the lift mast side are rigidly interconnected by a traverse type longitudinal beam 14 which extends approximately at mid-height of the columns.
  • two L-shaped transverse beams 15 have an upper leg fastened in a symmetrically equal manner to the longitudinal beam.
  • These two transverse beams 15 carry the foot board 8 and are fastened at the outer end of their other leg to a longitudinal beam 16 which rigidly connects the two columns 12 and 13 at the side further away from the lift mast 2.
  • the columns 10, ll, 12 and 13 of the transverse beams 15, and the longitudinal beams 14 and 16 are so dimensioned as to strength that they are able to absorb the highest moment which can occur in the load receiving means in question for the attachment to the lift truck under the most unfavorable load distribution.
  • This thereby provides a possibility for using the lift truck frame structure for all possible customary requirements provided the dimensions are changed correspondingly.
  • the lift truck 1 of the form of construction of FIG. 1 is provided on the broad side with a fork lifter 20 and on the opposite broad side with a vertically displaceable table 21.
  • an access door 22 is arranged on the longitudinal side, namely at one end of the longitudinal side so that the lift truck must be moved out of the shelf corridor by as small an amount as possible.
  • a similar access might be provided additionally or alternatively at the other end of the longitudinal side of the lift truck as the walls of the lift truck have no supporting functions to fulfill.
  • FIGS. 4 to 6 A variation of the type referred to above is shown in the embodiment of FIGS. 4 to 6 wherein similar parts are similarly designated but with primes.
  • the travel drive generally designated 52 for driving the wheels 54 at the upper end of the masts 2 is provided to permit the rolling of the device along the rail trackway 6 which is located adjacent the top of the mast 2.
  • the lift truck 1, l' is designed primarily as a basket type stand 7, 7 for the operator.
