Abstract

ABSTRACT OF THE DISCLOSURE:

Mixed usage vehicle for towing and for hoisting loads. The technical problem is to provide an air-transportable vehicle having reduced size and improved performance. The vehicle comprises a platform disposed to the rear of the driver's cab and bearing a telescopic crane which operates both in hoisting and handling loads and in towing and recovering broken down vehicles. The crane is adjustable between a horizontal retracted working position in which it can support a towed vehicle, and a raised and extended position in which it can be used for hoisting loads. The invention's main application is for a technical support vehicle accompanying a group of autonomous vehicles in desert regions.

Description

~2~

The present invention relates to a cross-country automobile vehicle of the kind usable for towing and for hoisting loads, comprising a platform dlsposed to the rear of the driver's cab.
In the automobile industry vehicles known as "recovery", vehlcles are available whose function is -to recover and tow another vehicle which has broken down and which usually have a towing hook fixed on a cable wound on a winch, solid with a frame of the vehicle and enabling the broken down vehicle -to be towed in a raised position or hoisted on the rear platform of the recovery vehicle. In the field of handling and hoisting heavy loads, various systems are available and in particuler, various kinds of cranes of which some can be installed on heavy vehicles such as trucks. However the cranes are usually small and are basically rotatable pulley hoists or small derrick systems with limited rotational ability, or alternatively strong capacity cranes which are very bulky but only have a limited jib reach.
A requirement has appeared for a cross-country automobile vehicle which can perform both functions, towing vehicles and hoisting loads, and featuring the reduced size of a light vehicle so that it is air transpor-table and an ability to handle heavy loads with large jib reaches, par-ticularly with a view to usage as dual function vehicles in a family of vehicles forming a unit which is autonomously mobile, for example for studies and research in desert zones.
According to the present invention, there is provided a vehicle for lifting and towing loads, comprising: a crane for lifting and towing loads, said crane comprising an extensible crane boom pivotally and rotatably mounted to said vehicle wherein said crane boom has a plurality of hoisting positions and a relatively -~ retracted and generally horizontal tow position; lifting O

jack means for lifting said boom; and a crane boom support, coupled to an end portion of the vehicle, for engaging the crane boom in its tow posltion to support -the crane boom while the crane is towing a load, said crane boom support being extensible.
According to the present invention there is also provided a cross-country automotive vehicle of the type intended for use in towing and hoisting operations and including a driver's cab and a platform a-t the rear of the cab; a dual-function telescopic crane for towing and hoisting loads, said crane being operable between a first horizontal retracted work position for use in load towing operations and a second lifted extended work position for use in load hoisting operations; said crane having a telescopic boom provided with a hook tackle-block at the free end thereof, which boom in said first work position extends along and slightly beyond said platform, and lifting jack means for lifting said boom. The invention is characterized in that: said boom is mounted on a crane support, on said platform, for pivotal movemen-t about a vertical axis; said liEting jack means comprise at least one jack mounted between said crane support and said boom between the ends of said boom; in said first position, said crane boom bears, at the free end therreof, on at least one support articulated at one end on said boom and at the other end on said platform, said support being adjus-table in length.
This arrangement enables a vehicle in accordance with the invention to have appropriate dual functions of hoisting and towing, while present a reduced overall size and an adjustable jib reach.
These arrangements give the vehicle reduced size both in height and length (and also in width) when the boom is retracted, which enables the vehicle to be air-` - 2'~

~LZ~

transportable. The swivelling and extending of the crane gives a high capacity formanoeuvre both radially and angularly.
Other features and advantages of the inventlon will appear from the following description of a preferred embodiment given by way of example with reference to the accompanying drawings, in which:
- Fig. 1 is a rear perspective view of a vehicle in accordance with the invention.
- Fig. 2 is a diagrammatic side elevational view of the vehicle of Fig. 1 with a boom of a crane in two working positions.
- Fig. 3 is a partial rear view of the vehicle operating as a lifting or material handling appliance.
- Fig. 4 is a diagram of the loads which can be handled by the crane as a function of the adjustable reach of its jib.
In Fig. 1, a vehicle in accordance with the lnvention is shown generally, and comprises an ordinary chassis 1 mounted on wheels 2 and bearing a cab 3 disposed at the front of the vehicle, and a horizontal rear platform ~. The platform 4 supports a crane indicated generally by the reference 5, and comprises a telescopic boom 6 which can pivot vertically on a crane support 7 fixed rotatably 25 , on the platform 4 and bearing on one side a seat 8 for an operator and a control panel 9 of ordinary kind shown very s c - 2a -and, on the other side, a spare wheel forjthe vehicle. In addition, the vehicle comprises four telescopic ide feet, which are con-nected to telescopic horizontal cross-beams I2 and which, ~hen extended as shown in Fig I bear on the ~round to stabillse the whole vehicle on the terrain.
In Fig I, the crane 5 ls shown swivelled sideways at a certain angle relative to the longitudinal axis of the vehlcle and in a position in which its telescopic boom is retracted. Fig 2 shows the crane 5 broug'nt into the longitudinal axis of the vehicle in a lowered position shown in full lines, ln which the boom 6 is horizontal and retracted and in an oblique position shown ln chain dotted lines, in which the boorn 6 is raised and extended. Moreover, in Fig 2, the vertical side feet II are in a non-operative retracted positlon.
~5 In the following description, reference will be made indif-ferently to Figs I and 2.
The telescopic boom 6 of the crane 5 comprises a first boom part I~ which can pivot vertically on the crane support 7 and a second sLiding part I4 carrying a hoist pulley block I5. The part I4 can slide within the boom part I~ under the action of a hydraulic ram I6, whose rod is solid with the boom part I4 and ~hich is mounted inside the part :t3 Or the boom 6. Otherwise, the pulley block I5 ~-:ries a hcist hook I~ by maans o~` a cable I9 w~.ich is wo mc ~n a hydraulically operated winch 20 installed on the crane support 7, As may be seen in the drawings, the boom 6 of the crane is connected to the base of the crane support 7 by two coupled parallel hydraulic rams having pivoting connections such as 22 shown very schematically in Figs 1 and 2 connecting the rams to the boom 6 ap-proximately in the middle of its retracted length. In addition, in its retracted hori~ontal position (shown in full lines in Fig 2), the boom rests on two generally vertical crutches or removable la-teral support~ 2~ close to the free rear end o~' the boom carrying the pulley block I5, the crutches 2~ being disposed on opposite sides of the booln ~ and connected to it by hinges 24 and being connected to the rear of the pla~form L~ by hinges 25. The hinges 21~ and 25 are for exarnple o~ the klnd comprising a lug bearing a shaft on 8~ ^

which the support can plvot. The supports 2~ are also adJustable, for example they may be telescopic (as shown) comprising a lower member 26 which can slide and be locked by any suitable mean.s indicated by the reference 27 withln an upper ~.ember of cooperating shape.
As already indicated, and in accordance with the inven-tion, the vehicle also comprises vertical lateral feet II each of which contains a hydraul-lc ~ack such as 29 (Fig I) whose body 30 is solid ~llth a top part 3I of the foot and whose rod 32 is solld I0 with a bottorn part ~3 of the foot II and which itself is solid with a horizontal shoe for be~ring on the ground, for example.
The ~acks 29 ~ay be operated by means of individual levers 34 which control the flow Or hydraulic rluid to operate the Jacks.
The feet II are fixed on both sides Or the vehicle to telescopic I5 horizontal cross-heams I2 which can be extended and retracted in part of the structure Or the platrorm 4 by means Or internal hy-draulic rams such as ~5 whose body ~6 is solid with the platf`orm and whose rod 37 ls hinged on the cross-beam I2.
To improve the stability of the vehicle, it also com-prises a ballast 38 (Fig 2) formed by a layer of concrete inserted horizontally between the chassis I of the vehicle and the plat-form 4.
'rhe hydraulic operating system WLll ilO~ ~e descr~bed, controllin~ the different~rc~ms for raising and extending the boom 6 f the crane and the different ~acks for ad~usting the belescopic feet II and their horizontal cross-beams I2. The chambers of the rams 2I ror raising the boom 6 are connected by a distributor indicated by the ref`erence 39 to a fluid pump 40 through flexible conduits 4I, while the ram I6 is similarly connected (by means not shown) to the distributor 39i the chambers of the jacks such as 29 and 35 are connected by ;flexible conduits such as those indicated by the references 42 and 43 and by individual distributors ~not shown) to the main distributor 39. A fluid reservoir 44 installed behind the cab 3 Or the vehicle is connected to the fluid pump 40, which itself is operated by a power take-off on the output of the gear-box 45 from the main drive engine (not shown) of the vehicle.
The vehicle, ln accordance with ;the invention, is used as follows : -I) ~len the boom 6 of the crane is horizontal and retracted (see Fig 2 - position in full lines) the boom only e~tends heyond the rear of the vehicle by its rear end carrying the pulley block I5 and the towing hook I8. In this position, the boom 6 can swivel through a certain angle relative to the ~ongitu-IO dinal axis, or can be aligned with this axis to tow another vehicle~
which has broken down for example, the boom then being fixed and held by the rear supports 23.
2) ~len the vehicle is to be used for hoisting and handling material (Fig 2, raised position of the boom shown in I5 chain dotted lines in Fig 2, and Fig ~), the boom 6 is raised by operating the rams ~I, and extended to the desired length by ope-rating the extenslon raln Io, and the crane support 7 is swivelled to the side~as desired; the wirlch 20 may then be actuated to drop the hook I8 to the level of the top of` a load to be lifted~ such as a container 46 disposed on another vehicle 47, for example.
Previous to the operation of actually hoisting the load~ the vehicle accordlrlg to the inventlon bearin~ the crane 5 (sr,own on the lert in Fig ~) is stab-ilised by extending sideways the telescopic cross~
beams I2, and controlling the extension Or the vertical telesco-plc feet II so that they bear firmly on the ground to ensure a more stable carriage of the vehicle bearing the crane and enabling a higher load moment and ]onger lateral hoist distance. Once the stabiliser feet are ad~usted, the load 46 is attached to the hook I8 by means of suitable slings 49 or the like, and it is then noisted by actuating the hydraulically onerated winch driven by the fluid ~ump 40 in the usual ;ay (not sho~m!.
~lg 4 is a diagr~m relating to the performance of the ~rane 5 on a vehicle in accordance with the invention, from which can he read off directly the 103d (in kg) which may be hoisted at a given distance sideways from the longitudinal axis 50 of the ~-ehicle, at a given inclination. In the diagram, the abscissa axis , ~22~ ~30 .," .

. ' is graduated in metres and represents the dlstance from the axis 50 of the vehlcle at ground level, while the ordinate axis graduated in metres gives the height of the tip of the boom above the ground. In addition, the re~erence 5I indicates the axis of rotatio~ o~ the boom 6, and the chain dotted lines represent three inclined positions, 52, 53 and 54 corresponding to respec-tive angles of ~ 75, ~ 50 and - I5 measured algebraically relative to the abscissa axis. Thus, for example, if the boom 6 is-extended to a length of 8 metresl its hook I8 can hoist a load ol IO 5 tonnes at a l.ateral distance o~ 4 m and for a height o~ 6J6 metres ror the hook I8.
