Definitions
- ABSTRACT A lift truck is stabilized in the aisle of a material storage facility by a pair of trolleys which travel on parallel horizontal guide rails on opposite sides of the aisle.
- Releasable connecting means engage the lift truck as it enters the aisle to latch the trolleys to the lift truck as it operates within the aisle. On movement of the truck from the aisle the latch means automatically operate to disconnect the trolleys from the lift truck, the trolleys staying on the guide rails in the material storage facility.
- the present invention employs a pair of trolleys which ride on rails at opposite sides of the aisle of a material storage facility.
- Releasable connecting means are provided to releasably secure a lift truck to the trolleys when it is driven into the aisle between the trolleys.
- the releasable connecting means automatically disconnect the trolleys from the lift truck when the latter is driven from the aisle thereby leaving the trolleys on the rails at the end of y the aisle in condition for re-entrance of the lift truck.
- a primary objective of the present invention is to provide a means for achieving high stacking with a lift truck in. a narrow aisle facility while maintaining good lift truck stability.
- This invention is particularly useful in connection with an order picker type truck engaged in high level retrieval.
- an order picker truck the operator is the order picking attendant who rides the carriage of the lift truck up and down to pick the materials from various points in the warehouse, and, in the interest of safety, it is desirable to prevent lateral and forward tilting of the truck.
- FIG. 1 is a top view of an order picker lift truck in an aisle of a material storage facility
- FIG. 2 is a side view of the lift truck illustrated in Referring to the drawings, a material storage facility 11 includes material receiving shelves 12 mounted on support structures 13 at opposite sides of an aisle in which an order picker lift truck 14 is disposed.
- a pair of horizontally disposed parallel guide rails in the form of channels 16, 17 are securely fastened to the support structures 13 as by welding.
- the channels are disposed with their open sides in confronting relation to one another.
- the lift truCk14 includes a mast 18 and a carriage 19 with order picking station 21.
- a conventional operators station 22 is provided for the truck so that the operator may operate the truck in a normal manner when it is not in the aisle of the material storage facility. When the truck is within the aisle of the material storage facility, the operator rides on the order picking station 21 where appropriate controls 23 are located for operating the truck.
- a drive-in attachment 26 is provided to releasably connect the lift truck to the guide rails to stabilize the lift truck against lateral and forward tilting.
- the attachment 26 includes a pair of trolleys 27, 28 with longitudinalmembers 29, 31 disposed alongside the channels 16, 17 and to which'front and rear rollers 32,33, 34, 36 are rotatably mounted. These rollers are of a size permitting them to be disposed between the upper and lower flanges of the channels 16, 17.
- the trolleys 27, 28 also includes latches 41, 42 adjacent the rear rollers tive latching parts in the form ofpockets 51', 52 in laterally opposite sides of the lift truck 14.
- the trolleys 27, 28 are interconnected by a transverse beam 56 secured by welding to the lower front end of the members 29, 31.
- a pair of upright legs 57, 58 are secured as by welding to the forward ends of the members 29, 31 and are reinforced by braces 59, 61.
- the upper ends of the legs 57, 58 carry brackets 66, 67 having downwardly facing abutment surfaces 68 which are adapted for cooperative engagement 'with upwardly facing abutment surfaces 69 formed on lugs 71, 72 on laterally opposite sides of the front of the truck.
- the truck is operating in the aisle of the material storage facility and the latches 41, 42 have been cammed to their locking positions by the vertical walls of the channels 16, 1.7.
- Apparatus for guiding and stabilizing a lift truck in the aisle of a material storage facility comprising:
- a pair of laterally spaced trolleys including 3 a pair of longitudinally extending members disposed alongside said rails, front and rear longitudinally spaced roller means on each of said members adapted for cooperative engagement with said guide rails for longitudinal movement therealong and whereby upward movement of said members is restrained, and
- said releasable connecting means includes a releasable latch shiftable between latching and nonlatching positions which automatically moves to its latching position for cooperative engagement with said lift truck when the latter is driven between'said trolleys.
- said retaining means comprises abutments on said latches and rails which engage when the truck is backed from between said rails.
- said latches include fingers adapted to cooperatively engage pockets in transversely opposite sides of said lift truck when said latches are in their latching position.
- Apparatus for guiding and stabilizing a lift truck in a material handling facility of .the type having support structures on opposite sides of an aisle comprising:
- a pair of laterally spaced stabilizing trolleys reciprocably mounted on said rails, respectively, each including front and rear rollers cooperatively engaging the associated rail and latch means mounted on said trolleys and operable to connect said trolleys to said lift truck by engagement with said cooperative latching parts in response to said truck being driven between said trolleys and rails, and means in said guide rails operable to disconnect said trolley from said lift truck in response to said truck being driven from said aisle.
- said trolleys each includes a frame member and wherein said rollers and latches are pivotally mounted on said frame members and further comprising means automatically operating said latches on movement of said truck into said aisle between said trolleys to releasably connect said trolleys to said truck and automatically operating said latches on subsequent movement of said truck from said aisle to release said truck from said trolleys.
