secured in the passages 31 and 38 respectively by the locking pins not shown which engage in locking pin passages 73 and 74 and are secured therein by a locking member as described in the present applicant 39 s earlier application no pct au2015 000460 although other locking pin assemblies would be suitable the inclined bottom face allows the outermost passage 64 to be positioned lower in the end piece then would be the case without the inclined section as can be seen in fig1 a horizontal line passing through the centre of passage 64 and pin 31 therein is lower than centre line 67 passing through the centre of connecting tube 53 which will be described in more detail later thereby providing better performance for the spreader bar as a whole fig1 shows that passage 65 is spaced horizontally from passage 64 by a distance of 750 mm and is also spaced vertically from passage 64 by a distance of 400 mm in this case in which the passages 64 and 65 are designed to take 6 inch diameter pins the length of each space horizontal and vertical is selected to achieve a specified angle u201c b u201d to the horizontal for a line passing through the two pin passages as can be seen in fig1 depending on the bucket and material with which the spreader bar is to be used it will be appreciated that the horizontal spacing of 750 mm or whatever the case may be results in the length of the spreader bar between the vertical plane containing the centre of passage 65 where the upper voice chain is connected is significantly less than it would be if the two passages were aligned vertically.
