Fig. 10 is a detail side elevational view showing a front mounting arrangement for the load carrier.
Referring to the drawings, there is illustrated a road vehicle according to the invention, indicated generally by the reference numeral 1. The road vehicle 1 has a chassis 2 mounted on wheels 3. An engine and driver’s cab 4 are mounted at a front end of the chassis 2. A load carrier 6 associated with the chassis 2 is demountably secured on the chassis 2. The load carrier 6 includes a mounting frame 7 for engagement with the chassis 2. A ram operated mechanism, indicated generally by the reference numeral 8, is operable to move the mounting frame 7 between a raised demounting position, as shown in Fig. 1, and a lowered chassis engaging position in which the mounting frame 7 sits on top of the chassis 2 (Fig. 2 shows the mounting frame 7 partially lowered onto the chassis 2). A stand 10 is provided for supporting the load carrier 6 in the raised position as shown in Fig. 1.

-4The ram operated mechanism 8 includes a ram 14 which is operably connected to an associated folding linkage mechanism having an inner link 15 and an outer link 16. An inner end 17 of the inner link 15 is connected by a pivot pin 18 to the chassis 2.
An outer end 19 of the inner link 15 is pivotally connected to an inner end 20 of the outer link 16 by a pivot pin 21. Rollers 25 are pivotally mounted at the outer end 23 of the outer link 16 and engage with a rubbing plate 26 on an underside of the mounting frame 7. A guide arm 28 is pivotally connected to the outer end 23 of the outer link 16 and extends to a pivot mount 29 on the chassis 2 spaced forwardly of the pivot mount 18. This guide arm 28 constrains the outer end 23 of the outer link 16 to move primarily in a vertical direction as the ram 14 is extended and retracted although the outer end 23 will of course move through an arc as the guide arm 28 pivots about the pivot mount 29.
The ram 14 has an inner end 32 pivotally connected to the pivot pin 18 on the chassis 2 and an outer end pivotally connected at 35 to the outer link 16 intermediate the inner end 20 and outer end 23 of the outer link 16. It will be noted from Fig. 4 that two pairs of links 15, 16 are provided with the ram 14 housed therebetween and operating both pairs of links 15,16 together. Operation of the ram 14 moves the links
,16 between a folded stored position, as shown in Fig. 4, on the chassis 2 and an opened position as shown in Fig. 3 for raising and lowering the mounting frame 7 on the chassis 2.
Mounting pins 40 project laterally outwardly on opposite sides at a front end of the mounting frame 7. Each mounting pin 40 locates in an associated cradle 41 at a front end of the chassis 2. Similarly, central mounting pins 42 project laterally outwardly at opposite sides of the mounting frame 7 for engagement with associated intermediate cradles 43 on the chassis. At a rear end of the mounting frame 7, mounting brackets 45 are provided on each side of the mounting frame 7 for complementary engagement with associated mounting pins 46 which extend laterally outwardly at a rear end of the chassis 2 below an upper support surface 27 of the chassis 2 upon which the mounting frame 7 sits in the lowered position. Thus, the rear end of the mounting frame 7 is pivotally mounted on the chassis 2. Fig. 9 shows the arrangement in more detail. The mounting bracket 45 has an inverted U-shaped
0552
-5member 48 with an outwardly tapered mouth 49 for reception of the mounting pin 46 on the chassis 2. A locking pin 50 is engagable within associated through holes 51, 52 in the U-shaped member 48 to retain the pin 46 in engagement with the mounting bracket 45.
Fig. 10 shows the mounting arrangement between the front end of the chassis 2 and the front end of the mounting frame 7. The cradle 41 has a U-shaped receiver 55 with tapered inlet 56 for reception of the mounting pin 40 on the mounting frame 7. A locking pin 58 engages through holes 59 in the receiver 55 to lock the pin 40 in engagement with the receiver 55. The centre mount 42, 43 is of similar construction.
The support stand 10 comprises a pair of front ground engaging legs 60 and a pair of rear ground engaging legs 61. Each front leg 60 has an upright post 62 with an inwardly extending support arm which engages with a complementary receiver socket
63 on the mounting frame 7. Similarly, each rear leg 61 has an upright post 65 with a cylindrical support arm 66 at its upper end which engages within a complementary cylindrical socket 67 on the mounting frame 7, thus forming a pivot connection between the rear legs 61 and the mounting frame 7.
In use, Fig. 1 shows the mounting frame 7 supported on the support stand 10. The chassis 2 is reversed in under the mounting frame 7, as shown in Fig. 1. The ram 14 is operated to engage the rubbing plate 26 on the underside of the mounting frame 7 with the lifting mechanism 8. It will be noted that the rollers 25 engage the rubbing plate 26 on the front half of the mounting frame 7. As the rollers 25 move upwardly, the mounting frame 7 pivots about the socket 67 which engages the rear leg 61, lowering the rear mounting bracket 45 into engagement with the pins 46 on the chassis 2. The locking pins 50 are then inserted to pivotally secure the rear end of the mounting frame 7 on the chassis 2. The rear mounting legs 61 are then removed, pivoting the mounting frame 7 upwardly further, if required, to enable their removal. By retracting the ram 14, a front end of the mounting frame 7 pivots downwardly about pins 46 and the front legs 60 can be removed. Further retraction of the ram 14 lowers the mounting pins 40, 42 on the mounting frame 7 into their associated cradles 41, 43 on the chassis 2. After lowering the ram 14 fully, the mounting pins 40, 42 are secured in their cradles 41, 43 by the locking pins 58.

-6Removal of the load carrier 6 from the chassis 2 is the reverse of the abovementioned procedure with the exception that the front legs 60 are mounted on the mounting frame 7 after the rear legs 61.
It will be appreciated that any suitable load carrier may be provided on the mounting frame 7. In the illustrations, a mixer bottle for cement has been shown. However, other types of load carriers may be provided, for example, a tipper body or a block body may alternatively be provided on a suitable mounting frame 7. Thus, advantageously the vehicle can be used for a number of different functions by simply changing the load carrier 6 as required.
Advantageously only a single ram is required to allow changing of the bad carriers on the vehicle chassis. The system is relatively simple allowing cheap manufacture and simple reliable operation in use.
The invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail within the scope of the appended claims.
