Abstract

A side-shift attachment for a fork lift truck comprises a part-circular bearing surface 1 for attachment to the lift carriage of the truck and a subframe 7, 8, 9, to which forks or other load engaging devices may be secured, having a bearing member 3 complementary to the bearing surface 1 and arranged to slide therealong under the action of a hydraulic piston and cylinder lever 9. <IMAGE>

Description

SPECIFICATION Forklift shift attachment This invention is concerned with improvements in or relating to lifting apparatus, particularly lifting apparatus associated with a self propelled motor vehicle, commonly known as a forklift truck. Forklift trucks conventionally have means for raising and lowering a load and it is also known to provide means for moving that load sideways relative to the median line or central backwards and forwards axis of the truck. In referring to such trucks as forklifts it will be appreciated that attachments other than forks are well known for use with the lifting mast of a forklift truck and the expression herein to forklift includes other attachments for lifting loads other than with the conventional forks.
An object of the present invention is to provide a side shift attachment for use with a forklift truck which gives improved visibility and which is relatively simple to manufacture and to attach to a conventional truck without substantial modifications.
The present invention provides a side shift attachment for use with a forklift truck comprising a first bearing member for securing to the frame of the forklift truck, said bearing member extending substantially the width of the truck, a co-operating second bearing member secured to a sub-frame, means for locating the second bearing member in slidable connection relative to the first bearing member and means for moving the second bearing member relative to said first bearing member, so that the sub-frame moves side ways relative to the truck. In a particular embodiment the first bearing member is a circular or part-circular rod and the second bearing member is a part tube of the same diameter as the rod and adapted to slide thereon. The means for moving the sub-frame relative to the forklift truck comprises a hydraulic piston and cylinder.
Referring now to the drawings: Figure 1 illustrates in exploded manner the parts and components of the attachment according to the present invention; Figure 2 illustrates the attachment according to the present invention just before securing to the forklift truck; and Figure 3 is a side view similar to Figure 2 showing the attachment secured to a forklift truck; and Figure 4 is a perspective view showing the sub-frame assembly according to the present invention.
In the Figures a first bearing member 1 consists of a circular or semi-circular rod having an ear 4 secured thereto and having a groove 1 a for being received and secured to a frame 10 of the forklift truck. A sub-frame comprises vertical members 8, a horizontal member 9 and an attachment bar 7 having a pierced ear 5 depending therefrom. The attachment bar 7 is suitable for securing for example forks 11 thereto or any other load lifting frame or attachment according to the known art of forklift trucks.
Member 1 is secured to the frame 10 of the forklift truck and has mounted thereon a cooperating second bearing member 3. Member 1 is part circular in cross section and member 3 is of a co-operating cross sectional shape, preferably slightly more than a semi-circle so as to ensure its retention on member 1. As will be seen from Figure 2, the bearing member 3 is able to rotate about the central axis of the bar 1.
To secure the lower end of the attachment to the frame 10 to the forklift, a hinged clip 14 is pivoted at 13 to a member 12 secured to the frame member 9 and is provided with a nose 17 which extends over a ridge 1 5 formed on the frame 1 0. When the nose 1 7 engages over ridge 1 5 the clip is secured in position by a pin 16 extending into member 12 as will be seen more clearly in Figure 4. The sub-frame is thus secured to the forklift truck in a manner which permits second bearing member 3 to slide along bar 1. A hydraulic ram comprising a hydraulic piston 6 and cylinder 2 is secured by a bolt to the ear 4 secured to member 1 at one end and the piston 6 is secured to the apertured lug 5 mounted on member 3 at the other end.Operation of the hydraulic piston 6 enables the sub-frame 7, 8 and 9 to be moved sideways in either direction relative to the central axis of the forklift truck.
It is thought that the present invention provides a simple and useful side shift attachment for use with forklift trucks.
Claims
1. A side shift attachment for use with a forklift truck comprising a first bearing member for securing to the frame of a forklift truck said bearing member extending substantially the width of the truck, a co-operating second bearing member secured to a sub-frame, means for locating the second bearing member in slidable connection relative to the first bearing member and means for moving the second bearing member relative to said first bearing member so that the sub-frame moves sideways relative to the truck.
2. A side shift attachment according to Claim 1 wherein the means for moving the second bearing member relative to the first bearing member comprise a piston and cylinder device.
3. A side shift attachment according to either Claim 1 or Claim 2 wherein the first bearing member comprises part-circular bar extending transversely of the width of the truck and the second bearing member has a co-operatingly shaped part-circular portion for engagement with the part-circular rod defining the first bearing member.
4. A side shift attachment according to any of the preceding claims wherein the first and second bearing members are located at the substantially uppermost position of the side shift attachment relative to the frame of the forklift truck.
5. A side shift attachment according to Claim 4, further including means at the lowermost
