Claims. (01. 214-620) This invention relates to a lifting attachment for a fork lifting truck, and more particularly to such type of attachment for use in handling a cargo carrying unit.
An object of the present invention is to provide a lifting attachment which is capable of ready placement upon a cargo carrying unit, and which when so placed is capable of receiving with facility the lifting forks of .-a truck lift.
Another object of the present invention is to provide a lifting attachment which is adapted to receive the lifting forks of a truck lift from any direction.
A further object of the present invention is to provide a lifting attachment which is highly efiicient in action, and commercially practical.
Other objects and advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings,
wherein: p I v Figure l is a side elevational view of the front of a fork lift truck equipped with the fork lifting attachment of the present invention and supporting a cargo carrying unit.
Figure 2 is a top plan view of the assembly of Figure 1.
Figure 3 is a perspective view of the fork truck lifting attachment according to the present invention.
Figure 4 is a top plan view of a modified form of the fork truck lifting attachment according to the present invention.
, Figure 5 is an enlarged fragmentary view of an end portion of one of the legs illustrating the hoisting chain and its connection thereto.
Figure 6 is a sectional view taken along theline 66 of Figure 5.
Referring to Figures 1 and 2 of the drawings, the numeral 10 designates a conventional fork truck on the front H end of which is mounted alifting carriage 11 for vertical sliding movement, the carriage having spacedlifting forks 12, two in number, projecting horizontally therefrom. Since the lifting truck forms no part of the invention the foregoing broad description of same is believed to be amply sufiicient for a proper understanding of the lifting attachment of the present invention for such truck.
The lifting attachment of the present invention, Figure 3, comprises a pair ofbeams 14, preferably I beams, arranged in intersecting crisscross relation and secured together at the crisscross region to thereby form ananchor 15 having a plurality oflegs 16 diverging therefrom. Aloop 17 is positioned below and extends longitudinally of each of thelegs 16 intermediate the free end thereof and theanchor 15 and is dependingly supported from the adjacent leg. It is to be noted that the spaces within theloops 17 ofadjacent legs 16 are in alignment with each other, thereby enabling the loops of adjacent legs to receive together one of theforks 12 of thelifting carriage 11. Alifting chain 18 is operativelyconnected to each of thelegs 16 adjacent the free end thereof and has one end provided with means or hook 19 for attachment to a cargo carrying unit. As shown in Figure 3, each of thechains 18 has the other end or the end opposite thehook 19 fixedly carried by the free end of theadjacent leg 16 as by means of aneye 20 which is fixedly carried by the free end of theadjacent leg 16.
The thus described lifting attachment, Figures 1 and 2, is secured to thecarriage 11 of the fork truck 10 by a flexible means orchain 21, the chain extending about theanchor 15 and thecarriage 11 with its free ends suitably 2 connected together. Thebooks 19 of thelifting chains 18 engagecomplemental rings 22 on the top of the legs of a cargo carrying unit designated by the numeral: 23.
The form of the lifting attachment of the present ino vention, Figures 4, 5 and 6, likewise comprises a pairof beams 14', preferably I beams, arranged in intersecting crisscross relation and secured together atthe crisscross region to thereby form an anchor 15' having a plurality oflegs 16 diverging therefrom. A loop 17' is positioned below and extends longitudinally of each of the legs 16' intermediate the free end thereof and theanchor 15 and is dependingly supported from the adjacent leg. Just like in the previously described form the spaces within the loops 17' ofadjacent legs 16' are in alignmentwith each other, thereby enabling the loops of adjacent legs to receive together one of theforks 12 of thelifting carriage 11. In this form, each of the free ends of thelegs 16 is provided with a vertically disposedsleeve 25. As shown in Figures 5 and 6, alifting chain 26 is slidably carried by thesleeve 25, the intermediate portion of the chain extending slidably through the sleeve and adjustably secured to the adjacent leg 16' and having one endprovided with means or hook 27 for attachment to a cargo carrying unit. Thechain 26 is adjustablysecured to the top of the adjacent leg 16' by extending it through a hook 29 carried by the top of such adjacent leg to the desired .extent and then twisting the chain until the complemental link engages against the hook, as clearly shown in Figure 6.
In use of the lifting attachment of the present invention, the attachment is placed upon the top of a cargo carrying unit such as illustrated in Figure l and indicated by thenumeral 23,- and thehooks 19 of thelifting chains 18 are in turn engaged with therings 22, whereupon the truck 10 is brought to a position such that it is adjacent to theunit 23. Thecarriage 11 is next elevated until theforks 12 are at an elevation so as to be received within the spaces of theloops 17 of theadjacent legs 16, and the truck then actuated to move it toward theunit 23 and cause theforks 12 to be received within such spaces. At this point, thebeams 14 are attached to thecarriage 11 by causing thechain 21 to extend about thecarriage 11 and theanchor 15 and suitably securing the ends of the chain together, the carriage is then raised sufiiciently to elevate theunit 23 from the floor, and the truck actuated to cause it to transport the unit to the desired location. When reaching such location, the travel of the truck is stopped, the carriage actuated to cause theunit 23 to be deposited upon the floor, and the lifting attachment then detached from the unit and the carriage.
It is to be noted that by virtue of the spaces of the loops of the adjacent legs being in alignment, the lifting truck may be moved toward the cargo carrying unit from any direction and cause the entry of the spaced lifting forks within the spaces of the loops of the adjacent legs.
Having fully described the invention, what I claim as new and desire to secure by Letters Patent is:
1. A lifting attachment for a fork lifting truck comprising a pair of beams arranged in intersecting crisscross relation and secured together at the crisscross region to thereby form an anchor having a plurality of legs diverging therefrom, a loop positioned below and extending longitudinally of each of said legs intermediate the free end thereof and said anchor and dependingly supported from the adjacent leg, the spaces within the loops of adjacent legs being in alignment with each other to thereby enable the loops of the adjacent legs to receive together a fork of a fork lifting truck, and a lifting chain operatively connected to each of said legs adjacent the free end thereof and having one end provided with means for attachment to a cargo carrying unit.
