Articulated mast for vehicles, in particular motor vehicles

For this application the priority of the corresponding British application no. 8823/68 of February 23, 1968 in Availed.

The invention relates to a jointed mast ^N for vehicles, particularly lorries, with a liftable and tiltable load stage and a rotatable about a vertical axis support base. The articulated mast consists of load parts that can be pivoted about horizontal pivot pins and has a main mast and at least one auxiliary mast; the main mast is received around a horizontal pivot pin in the support base, and the auxiliary mast or the outer auxiliary mast is pivotably arranged at the end of the adjacent mast part. There are also devices provided for rotating the support base around its vertical axis, for pivoting the main mast around its horizontal pivot pin arranged in the support base and for pivoting the auxiliary or auxiliary

masts around theirs at the end of the neighboring part Pivot pin arranged on the mast part; also are control gate directions on the load platform to operate the devices and devices for fixing the load platform in a horizontal position.

The object of the invention is to improve and improve such articulated masts in an economical manner to enlarge their scope.

In the embodiment according to the invention, the support, Base at the rear end of a transport vehicle, added so that the main mast is practically horizontal in its rest position and to the front of the vehicle is directed, the articulated mast is arranged in such a way that the auxiliary mast or the outer auxiliary mast is has a pivot angle of 180 ° or more compared to its neighboring mast part.

According to the invention is the main mast with the support base connecting pivot pins on a higher level than that Roof of the driver's cab of the vehicle.

In the rest position Xlang, the auxiliary mast or the outer auxiliary mast is lifted laterally and parallel to the adjacent mast partj, with which <sx is pivotably connected; From this position, in a plane parallel to the plane of the benacabartea, it can make an angle of 560 °. .swiveled'tJ.e3? dea *; ·

There is an advantage of the embodiment according to the invention in that the articulation of the articulated mast is is always on the side of the vehicle on which the job is located, so that you can see outside the traffic line is located.

Another advantage is given where dori access to a job is made more difficult by high obstacles, for example when the job is on the far side of a number of telegraph lines and if access is obstructed by power cables lower than the telegraph lines; the articulated connection of the articulated mast can be moved directly under the obstacle before the load platform is raised; this avoids the need for a large free space * ur performing the swivel movement as directed by the Articulated masts of known embodiments is required.

from the driver's cab, and when the latter is out its rest position is pivoted down, the load platform 20 can be brought into line with the entrance door of the driver's cab within the range of the vehicle width, so that the operating personnel can step over directly from the driver's cab onto the loading platform.

The pivoting movement of the main mast around its pivot pin in the support base is effected by a hydraulic, Piston-cylinder arrangement, the two ends of which are rotatable on the bolt 22 of the support base and on the bolt 23 of the main mast are received, wherein the pivot pins are stacked and parallel to the pin 14; the la order the pivot pin and the piston-cylinder arrangement. is such that the main mast from a horizontal position upwards through an angle of 105 ° and after can be swiveled at an angle of 15 ° at the bottom, the pivoting antenna has the purpose that the Load platform, by corresponding swiveling of the auxiliary boom, in a position below the driving plane of the vehicle can be lowered. The auxiliary mast is rotatable the hinge pin 24 is connected to the main mast in such a way that a pivot plane is parallel to the pivot plane of the main mast if j the auxiliary mast is at the same distance. next to the W

Main mast arranged that the auxiliary mast with its load platform can swing freely past the main mast.

The load platform is pivotable at the free end of the auxiliary arm tes recorded on the pivot pin 25.

To carry out the pivoting movement of the auxiliary mast about its pivot pin, a second hydraulic piston-cylinder arrangement 26 is provided, having one end about the B _e lzen 27 rotatably attached to the main mast and the other end by a pin 28 at the ends of the steering lever 29 and a Control lever 30 is arranged; the lever and the piston-cylinder arrangement are pivotable relative to one another. The free end of the steering lever 29 is pivotably received with the main mast on the pivot pin 31, which is arranged between the pivot pin 14 and the pivot pin 24, adjacent to the latter. The free end of the control lever 30 is pivotably fastened by the bolt 32 (FIG. 4) to a switching disk 33, which in turn is fastened to the auxiliary mast coaxially with the pivot pin 24. the Ifcdex disk has four rotary bores 34 which are equally spaced on a common pitch circle, each bore being able to serve to receive the bolt 32; the bolts 27, 28, 31 and 32 and the four holes of the index disc are all parallel to each other and to the bolt 24 »

the position of the bolts and the arrangement of the Piston-cylinder arrangement and the lever are such, . that the piston-cylinder arrangement and the lever move the auxiliary mast relative to the main mast at an angle of Can pivot 180 degrees or more; the four holes in the index disc enable the pivoting bow of the auxiliary mast Can be offset by 90 depending on the Kolbest cylinder arrangement and the levers to the main mast > when the bolt 32 is in the adjacent hole of the index washer is used. The main mast has, adjacent to the bolt 24, a section sleeve 35 (i "ig. 4), dif at each of four predetermined positions of the helper One of the bores is located coaxially to the main mast the index washer, so that a bolt can be inserted through the holes in the sleeve and this blocks the auxiliary mast to the main mast, so that the Auxiliary mast to the main mast "is established * by li of the bolt 32 successively in the four holes of the Index disc, the auxiliary mast can be swiveled at an angle from the main mast. The number of in equal Spaced holes may be two or more depending on the. Size of kungsbogen of the auxiliary mast, ..-.

The means of maintaining the loading platform in one horizontal position consist of a lever 36, the with one end pivotable on the support base by one Bolt 37, which is parallel at a distance from bolt 14, is received, while the other end of the lever is rotatable via a bolt 38 with an angle lever 39 connected rotatably mounted on a bolt 24; the bolts 37 and 38 'are parallel to each other and to the bolts 14 and 24. Dl © arrangement of the bolts is such that the distance between bolts 37 and 38 is the same as between bolts 14 and 24, »Nd that the distance between the bolts 38 and 24 of the is the same as between the bolts 37 and 14c On the angle lever and rotatable with it is a sprocket 40 or a pair of sprockets arranged whose teeth with f ^ en links of a chain or chains 41 in engagement stand, which drives a similar sprocket 42 or sprocket pair that rotates on the load platform on the Bolt 25 is attached. The lever and the chain drive ensure that the load platform to the auxiliary mast swiveled by an angle which is equal to and opposite to the sum of the swivel angles of the two mast parts relative to the support base.

A winch 43 is attached to the support base, and on the Bolts 14 and 24 and the bolt 25 of the load platform is each a freely rotatable wheel 44 arranged to guide a Hoist rope 45, which is attached to a load hook 46 by the winch leads, which is arranged below the load platform or below the free end of the main mast.

The side walls 47 of the load platform are foldable so that they can be folded up to reduce the Height of the platform during transport.

A stall frame 48 is arranged on the roof of the driver's cab in order to hold the load platform firmly in place when the vehicle is driven a long distance. ¹

The truck is equipped with extendable supports 59 »to prevent the chassis from swaying while working with the articulated mast. The interior of the truck is suitable for storage and transportation of tools, fittings such as street lights and the like. _;
