 The vehicle shown in Figure 1 comprises a conventional chassis 1 on which is stowed the lifting and handling equipment according to the invention.

 This equipment comprises a sub-frame 2 which extends over the entire length of the frame 1. This sub-frame 2 is equipped, at its front part, with a crane 3 and, at its rear part, various means 4 which allow to lock and / or move in association with the crane, various loads.

 In the example of Figure 1, the subframe 2 supports on its rear part, a bucket 5 of the waste bin type. A compactor 6 is interposed between the waste container 5 and the mast 7 of the crane 3.

 This crane 3 makes it possible to handle various loads to introduce them directly into the bucket 5, or to introduce them into the hopper 8 of the waste compactor 6.

 This waste compactor 6 is preferably stowed on the front face of the bucket 5. There are two cylinders 9 which serve to maneuver the piston 10 to press the waste and introduce it into the bucket 5 at the opening 11.

 The two cylinders 9 are anchored on the walls of the compactor. The piston 10 may comprise one or more telescopic flaps 12 which make it possible to obstruct the base of the hopper 8 when the waste is pushed towards the bucket 5.

 The bucket 5 can be guided and anchored on the subframe 2 via a cradle 13 which will be detailed below.

 The crane 3 consists of the mast 7 which forms its base. This mast 7 extends in height behind the cabin of the vehicle and above the upper level of this cabin.

 The mast 7 supports a head 14 which is pivotally mounted about a vertical axis. This head 14 is maneuvered by means of a drive member 15, of the rack type, arranged for example at the upper part of the mast 7.

 The boom of the crane consists of a first arm 16 hereinafter referred to as the offset arm. This arm 16 is articulated at the lower part of the pivoting head 14, around a horizontal axis 17. A jack 18 is interposed between the head 14 and the offset arm 16 to maneuver the latter around its axis 17 and pass it from an extreme horizontal position to another extreme substantially vertical position.

 This jack 18 is anchored on an axis 19 disposed at the upper part of the head 14 and on an axis 20 disposed at the end of the arm 16.

 Preferably, this arm 16 will be manipulated by two jacks arranged laterally, on either side of the head 14.

 The axes 17 and 19 are sufficiently spaced, and they are positioned in a plane which is perpendicular to the median plane of the sector corresponding to the two extreme positions of the arm 16, to provide maximum power to this arm 16, in all positions.

 The offset arm 16 supports the main arm 21 of the boom of the crane 3. This main arm 21 is maneuvered by means of a jack 22. The jack 22 is anchored on an axis 23 located on the arm 16 between the axes 17 and 20; the other end of the jack 22 is articulated on an axis 24 situated along the length of the arm 21.

 Preferably, the main arm 21 is of the telescopic type, maneuvered by means of a jack 25.

 The axes 20 and 23 are also arranged so as to offer maximum power to the arm 21, whatever its position.

 The main arm 21 may include, at its end, an additional arm 26 called the jib arm which offers an advantageous possibility of load offset during maneuvers near the cabin for example.

 This stem arm 26 is articulated around an axis 27 disposed at the end of the arm 21. A jack 28 shown in thin broken lines is interposed between the arm 21 and the stem arm 26.

 Figure 2 shows the crane 3 in a folded configuration. In this rest configuration, the crane extends in the longitudinal plane of the truck and partly above the cab.

 This crane has the advantage of keeping the vehicle with a reasonable size which allows it in particular to pass under bridges.

 FIG. 2 partially shows the vehicle equipped with an elevator 30 for small containers 31 of the city bin type.

 This elevator 30 is disposed laterally, at the level of the waste compactor 6.

 This elevator 30, shown in profile in FIG. 3, is either integral with the waste compactor 6 or with the subframe 2.

 This elevator 30, for small containers 31, makes it possible to increase the versatility of the vehicle equipped with a bucket 5 and a waste compactor.

 Figure 4 illustrates an operation of the bucket 5 to place it on the ground or to hoist it onto the vehicle.

 This maneuver is carried out by means of the crane 3, and in particular in the example shown, by means of a hook 32 disposed on the main arm 21 and of a sling 33 interposed between said hook 32 and a ring 34 disposed on the front face 35 of the bucket 5.

 These maneuvers of the bucket 5 are facilitated by the use of the cradle 13 which acts as a ramp.

This cradle 13 has at its rear and lower end rollers or a roller 36 in contact with the ground.

 A jack 37 is interposed between the subframe 2 and this cradle 13 to allow longitudinal maneuvering of this cradle in order to position it as required. This cradle is guided on the subframe 2 by means of rollers 41 arranged at the rear end of the latter.

 Figures 5 and 6 illustrate the movements of the bucket 5 to place it on the ground for example.

 Figure 5 shows the rearward movement of the bucket 5, by means of the cradle 13 under the effect of its operating cylinder 37. During this maneuver, the bucket 5 is accompanied by the crane 3 by means of a sling 43 interposed between the end of the bracket 26 and the ring 34 disposed on the front of the bucket 5.

 Note, Figure 6, the tilting of the cradle 13 and the bucket 5 under the combined effect of the cylinder 37 and the crane 3. When the bucket 5 is in contact with the ground, the forward movement of the truck allows this grab to leave the cradle 13 until it is completely deposited on the ground.

 FIG. 7 represents an arrangement of the bucket 5. This bucket comprises an intermediate partition 45 which makes it possible to separate waste in the case of collection of several types of products.

 Figure 8 shows the front panel 35 of the bucket 5. Note the ring 34 used to manipulate the bucket by means of the crane. Note also the opening 11 which allows the compacted waste from the compactor 6 to be introduced into the bucket 5.

 This bucket comprises, in a conventional manner, two longitudinal members 46 at its lower part, provided with fasteners 47 to allow its tipping from the rear for example.

 We also note, still on this front face 35 of the bucket, arranged between the side members 46, two rollers 48 of rolling, which cooperate with the cradle 13 during the maneuvers of the bucket relative to the truck.

 Figures 9 and 10 show a portion of the cradle 13 and in particular its rear part which is provided with rollers or rollers 36. This rear part comprises pawls 49 and 49 ', mounted on a transverse axis 50. These pawls 49 and 49' are used alternately to carry out maneuvers for translating the load placed on the cradle 13.

 FIG. 9 shows a pawl 49 in the active position for an operation for translating the load towards the front of the vehicle. During this maneuver, the pawl 49 'is in the rest position.

 FIG. 10 represents the pawl 49 ′ in the active position for an operation for translating the load placed on the truck, towards the rear of the vehicle. During this maneuver, the pawl 49 is in the inactive position.

 Figures 11 and 12 show a vehicle whose crane is equipped with a grapple for the collection of bulk waste and bulky waste of all kinds.

This grapin 51 has the advantage, as shown in Figure 11, of being able to position and store in the waste compactor, without harming the general size of the vehicle.

 FIG. 13 illustrates a use of the vehicle for selective collection of glass and paper for example. The waste container 53, suspended from the end of the crane 3, is emptied into one of the compartments of the waste container 5 '.

 The crane 3 allows, thanks to its main telescopic arm 21, to position the waste container 53 above one or the other of the compartments of the bucket 5 '.

 FIG. 14 illustrates a tilting operation of a bucket 5 by means of the crane 3. This tipping, around the rear transverse axis 54, of the sub-frame 2, is carried out directly by the crane by means of a sling 55 interposed between the front of the side members 46 of the bucket and the hook 32 located at the end of the main arm 21 of the crane.

 FIG. 15 shows the crane in the transport position but also in a position which corresponds to that of the start of a rear tipping operation.

 FIG. 16 represents the vehicle fitted with lifting and handling equipment, provided with an additional device which allows full power use of the crane 3.

 This additional device consists of a kind of stand 56 which extends between the rear axis 54 of the subframe 2 and, by means of a retractable extension 57, up to the upper part 58 of the mast 7 of the crane 3.

 The extension 57 is either of the type articulated on the end of the stand, or telescopic and lockable on said stand.

 A jack 58 is interposed between the stand 56 and the subframe 2.

 Figure 17 shows, in top view, the vehicle without the crane. Note the stand 56 which pretends from the rear of the subframe 2 and in particular from its axis 54 to the front part of said subframe. The jack 58 is interposed between a cross member 59 secured to the subframe 2 and an axis 60 located on the stand 56.

 This stand 56 and its extension 57 are in the form of beams arranged in the center of the subframe 2, in its median plane. They constitute a kind of strut or triangulation which increases the capacity of the crane 3.

 These capacities are for example used to mount a heavily loaded bucket 5 on the vehicle.

 This bucket 5 is raised, at its front part, by means of the crane and then it is pulled on the cradle 13, still by means of the crane.

 The upper end of the mast 7 may - include a special arrangement for accommodating the end of the stand, in the form of a shoe 61 or a yoke.

 Note also in FIG. 17, the cradle 13 in the form of a frame, guided on the rollers 41 located at the rear of the subframe 2, which rollers are mounted on the axis 54.

 The front part of the cradle 13 includes a locking mechanism which cooperates with the stand 56. This locking mechanism will be detailed below in FIG. 27.

 Figures 18 and 19 correspond to a use of the vehicle and its lifting equipment for the transport of standardized containers 5, provided with fastening means.

 For this type of container, the cradle 13 has transverse arms 62 arranged at its front part and at its rear part. These arms 62 have at their ends latches 63 allowing the container 5 to be hooked by its corners. These latches can also constitute longitudinal articulation axes which make it possible, cooperating with a bucket, to dump right or left using the crane to lift said bucket.

 The cradle 13 has a width which is greater than the width of the subframe 2. I1 rolls on the external rollers 4 disposed at the rear part of the subframe 2 and also, on rollers 64 arranged along the length of the subframe 2.

 Note also in this FIG. 19, the central position of the jack 37 which is used to maneuver the cradle 13 relative to the subframe 2.

 For this type of handling, the container 5 can receive a roller 65 anchored at its front part, to roll on the cradle 13.

 The container 5 is maneuvered by means of the crane 3 and, optionally, with the use of the stand 56.

 Figure 20 illustrates the versatility of the equipment by showing one of the multiple capabilities of the vehicle equipment. The crane 3 can be equipped with a lifting beam 66 which makes it possible to lift loads such as for example cars by taking them from the ground to deposit them on a plate 67 associated directly with the sub-frame 2 for example. This tray or floor 67 is supported by arms not shown, integral with the subframe. It can also be placed on the cradle 13, fixed to the arms 62.

 FIGS. 21 and 22 represent an arrangement of the end of the main arm 21.

 This main arm has an end section 70 on which the bracket 26 is mounted. This end section is associated with the main arm 21 by means of a pair of axes 71 and 72 which are perpendicular to the axis 25 which constitutes the articulation of the stem on this section 70.

 The axis 71 allows the section 70 to pivot so as to bring it back against the main arm 21. The axis 72 simply constitutes a locking axis of this end section 70.

 In the configuration shown in Figure 22, there is a significant reduction in the length of the crane.

 Figure 23 illustrates the operation of a bucket 5 with the use of the stand 56 as a strut. Note that the stand 56 can also be used to initiate tipping, as shown in FIG. 23, of a bucket articulated at the rear of the subframe 2, on the axis 54.

 FIG. 24 illustrates a vehicle simply equipped with all the lifting and handling equipment and in particular with the strut 56 which is folded and whose end section 57 appears, and with a cradle 13 placed on the subframe 2.

 FIG. 25 represents the rear part of the sub-frame 2 showing its end axis 54, the rollers 41 and latches 74 for the fixing of standardized containers for example.

 The stand 56 is articulated on the axis 54. It is maneuvered by its jack 58. This stand 56 can also be used, as shown in FIG. 26, for fixing the jack 37 which allows the longitudinal displacement of the cradle 13. For this purpose, the end of the stand has a yoke 76 and its end has a first orifice 77 for the passage of the axis 54 and a second orifice 78 for the passage of the anchoring axis of the jack 37.

 Figure 27 shows the locking means of the cradle 13 on the stand 56. These means consist of a hook 80 which cooperates with a fitting 81 secured to the stand 56. This fitting 81, which also appears in Figure 25, extends over a part of the length of the stand 56 so as to allow movement of the cradle 13 relative to the stand 56, while remaining locked relative to the latter.

 The hook 80 can be operated remotely by a jack 82 or any other means.

 The reference signs inserted after the technical characteristics mentioned in the claims are intended only to facilitate the understanding of the latter and in no way limit their scope.
