An attachment (1) for a fork-lift having at least one tine, said attachment (1) comprising at least one channel (2, 3) adapted to receive at least one said tine, lifting means provided to support articles intended to be lifted and adapted to receive one more accessories (24, 27, 30), and connecting means (11) adapted to secure said attachment (1) to the fork-lift.
Description
WO92/1~23 PCT/AV91/00569 21~1 26g FORX-LIFT ~T~AC~MB~T
~he present invention concern~ impro~ement~ to fork-lift~
and the like. In particular, this invention relate~ to an attachment for enabling fork-lifts to handle drums, machinery and other articl~s which are not readily accommodated on the tines of a ~ork-lift.
In Australia and many other ~ountries there are regulation~ governing the u~e of fork-lifts and the type of arkicles which may be handled. The~e regulation~ are principally intended to protect th~ safety of fork-lift operators and per~onnel who work in the proximity of fork-lifts. ~owever, these regulations al~o make i~ illegal to u~e presently-exi3t~ng fork-lift a~emblies to lift msny article~, ~specially article~ o~ irregular shape.
For example, if it iB desired to handle a large drum it i~
not practical (or permlssible) to balance the drum on the tine~ of the fork-lift, becau~e there i8 a sub~ antial danger that the drum will roll or topple off. In the pa~t, it has been prcposed to replace the ~ork-lift tines by a single jib from which a .hain depended, and to fix the chain to the drum or other article. This type of arrangement i~ prohibited by the ~a~ety r~gulations, b~cause of the likelihood that the forklift will tip over during handling, due to a shift in the centre of gravity.

In addition, because the single jib arrangement referred to above required removal of the fork-lift ti~es before fitting the jib, the procedure wa~ time-consuming and included the further danger that the tines of the fork-lift may not be replaced correctly.
The presen-t invention seeks to overcome or substantially alleviate the problems referred to above by providing an attachment for a fork-lift having at least one lifting tine, said attachment comprising:
at least one channel adapted to receive at least one said tine;
lifting means provided to support articles intended ~-to be lifted, said lifting means comprising a main plate having at least one lug, said lug b~ing integral with or rigidly attached to said main plate; and connecting means adapted to secure said attachment to said fork-lift.
Preferably, the attachment of the invention is designed to - be used with a forklift having a pair of spaced lifting tines and the attachment has a pair of channels, each of which is adapted to receive one tine. For the sake of convenience, the invention will be described hereunder with reference to this configuration, but it is to be understood tha~ the invention is not limited thereto.
In an especially preferred embodiment, the channels are designed so that the fork-lift tines may enter the ... ...... .

channels from one end o~ the channels or the other. In this way, ths attachment of the invention may be connected to the fork-lift from one side or the other.
When the attachment has one lug, it i~ preferred that the lug is located centrally on the main plate.
In one pre~erred embodiment of the present invention the attachment has two lugs, each lug is being located at one of the outer extremities o~ the attachment.
In another preferred embodiment of the present invention, the attachment has three lugs, one lug is located at each of the outer extremities of the attachment and one lug is located centrally. The central lug can be used to lift or handle relatively small or light articles while the outer pair of lugs is useful in the handling of heavy loads.
Since heavy loads can be secured to the attachment at these two spaced points, they may be lifted in a controlled manner. Thus, there will be less likelihood that the load will swing from side to side, or strike the fork-lift during lifting or transport.
