Abstract

The invention relates to an arrangement at a breakdown lorry 1. This has a lifting boom 2 extending centrally in the longitudinal direction of the lorry 1. In its forward end, the lifting boom 2 is swingably journalled around an axle 3 being arranged between the forward and the rear pairs of wheels 4, 5 of the lorry 1. The lorry 1 further has a lifting plane 9 arranged above the lifting boom for placing of a vehicle to be salvaged. The plane 9 extends from the driver's cabin 10 of the lorry 1 and towards the rear end of the lorry. In order to prevent the placed vehicle to bump against the driver's cabin 10 in connection with manoeuvring of the lifting boom 2, the loading plane 9 is swingably journalled at its forward edge around a crosswise extending axle 11. The latter is preferably arranged immediately behind the driver's cabin 10. The loading plane is slidably arranged on the lifting boom 2 at its rear edge. <IMAGE>

Description

- 7905003-5 E' Ändamålet med föreliggande uppfinning är att förhinïrefätï dylika skador" uppstår och detta åstadkommas därigenom att bärgningsbilen har de känne- tecken som framgår av bifogade patentkrav. 9 ^ Uppfinningen skall i det följande förklaras ytterligare med hänvisning till bifogade ritning som schematiskt i en sidovy visar ett utföringsexempel av en bärgningsbil enligt föreliggande uppfinning. - 7905003-5 E ' The object of the present invention is to prevent such damage " occurs and this is achieved by the tow truck having the characteristics characters which appear from the appended claims. 9 ^ The invention will be further explained in the following with reference to attached drawing which schematically in a side view shows an embodiment of a tow truck according to the present invention.

På ritningen är 1 en bärgningsbil med en lyftbom 2 som sträcker sig centralt i bilens längsriktning. Bommen är i sin främre ände lagrad kring en tväre gående axel 3, vilken är anordnad mellan bilens främre och bakre hjulpar 4 resp 5. Lyftbommen kan höjas och sänkas med hjälp av ett vid lyftbommens bakre ände verkande hydraulmanövrerat cylinderkolvaggregat 6. I lyftbommens 2 bakre ände finns en hydraulmanövrerad s k vikbom 7 som är utrustad med en likaså hydraulmanövrerad s k sticka 8 till vilken ett fordon som skall bog- seras kan kopplas på konventionellt sätt. Över lyftbommen 2 är anordnat ett lastplan 9 för uppställning av ett fordon som skall bärgas. Lastplanet 9 sträcker sig från bärgningsbilens 1 förarhytt 10 bakåt mot bilens ändparti. Enligt uppfinningen är lastplanet 9 vid sin främre kant vridbart lagrad kring en tvärgående axel 11 företrädesvis anordnad strax bakom förarhytten 10. Lastplanet 9 är vidare vid sin bakre kant utrustad med en glidsko 12 som är glidbart anordnad på lyftbommen 2.In the drawing, 1 is a tow truck with a lifting boom 2 that extends centrally in the longitudinal direction of the car. The boom is mounted at its front end around a crossbar moving axle 3, which is arranged between the car's front and rear wheels 4 resp 5. The lifting boom can be raised and lowered with the help of one at the lifting boom rear end acting hydraulically operated cylinder piston assembly 6. In the lifting boom At the rear end there is a hydraulically operated so-called folding boom 7 which is equipped with a also hydraulically operated so-called stick 8 to which a vehicle is to be towed can be connected in a conventional manner. A load plane 9 for arranging a vehicle is arranged above the lifting boom 2 to be salvaged. The loading platform 9 extends from the tow truck's 1 cab 10 backwards towards the end of the car. According to the invention, the loading plane 9 is at its front edge rotatably mounted about a transverse axis 11 preferably arranged just behind the cab 10. The loading platform 9 is further at its rear edge equipped with a sliding shoe 12 which is slidably arranged on the lifting boom 2.

Medelst en vid Iyftplanet 9 fixerad hållare 13 som delvis omsluter lyft- bommen 2 stabiliseras lyftplanet 9 mot sidorörelser.By means of a holder 13 fixed to the lifting plane 9 which partially encloses the lifting the boom 2 stabilizes the lifting plane 9 against lateral movements.

Enligt särskilda kännetecken för nppfinningen är lastplanet 9 strax bakom axeln 11 utrustat med stopporgan 14 mot vilka ett av ett uppställt fordons hjulpar är avsedda att ta stöd. Vidare bildar lastplanets 9 främre del en trubbig vinkel med lastplanet 9 i övrigt så att tillsammans med stopporga- nen 14 erhålles ett stabilt stöd för nämnda hjulpar samtidigt som dessa hindras att glida eller rulla bakåt.According to special features of the invention, the loading plane 9 is just behind the axle 11 equipped with stop means 14 against which one of a vehicle is parked pairs of wheels are intended for support. Furthermore, the front part of the load plane 9 forms one obtuse angle with the load plane 9 otherwise so that together with the stop 14 a stable support is obtained for said pair of wheels at the same time as these prevented from sliding or rolling backwards.
