Definitions

• the object of the present invention is to provide an attach ⁇ ment device for a crane of the type on a cross-country vehicle mentioned by way of inroduction, which constitutes a simple, reliable and non- expensive complement to a cross-country vehicle of this kind and this has been achie ⁇ ved by the features stated in patent claim 1.
• Fig. 1 shows diagrammatic from the side a crane stand accor ⁇ ding to the invention intended for a cross-country vehicle and provided with a crane therein, and
• Fig. 2 is a view straight from the rear of the crane stand with a crane and shown in a slightly larger scale.
• Fig. 3 shows in a view corresponding to Fig. 2 a modified design of a device according to the invention.
• Fig. 1 and Fig. 2 show from the side and from the rear respectively a device at a rear mounted crane stand for a light cross-country vehicle whereby the cross-country ve ⁇ hicle only is shown in Fig. 1 and in this only as fragmenta ⁇ ry mounting details 4,5.
• the device comprises a frame 1, which in the shown embodiment contains two upper 2 and two lower stays 3, which with each end is attached to the fixed details 4,5 provided on the vehicle, whereby the attaching points for the upper and the lower stays respectively are symmetrically arranged about the longitudinal axis of the vehicle, and the opposite ends of the stays are fixed in a plate 6, which supports a standing guide tube 7 for a crane post 8.
• the stays 2, 3 extend from their mounting points at the vehicle inclined to the rear, so that said plate 6 will be situated behind the rear rim of the vehicle.
• Two at the rear angled arms 9 extend from the mounting points of the upper stays 2, which at the centre above the first guide tube 7 support a second upper guide tube 10 for the crane post, which thus accurately will be guided by the two guide tubes.
• tow hook 16 connected to the plate 6, which hook 16 by a further forward directed stay 1 ⁇ is coupled to the regular attachment for a tow hook. Since the regular attachment for the tow hook is situated relatively far ahead in the rear part of the cross-country vehicle, and at least in the front of the crane stand, the regular tow hook could not be used in the intended way, when the crane stand with support leg was coupled to the vehicle. By moving the tow hook to the region for the plate, the tow hook will be available and a trailer coupled to this will not be obstructed in its turning by members situated at the rear.
• Fig. 3 is shown a view corresponding to that of Fig. 2 of a modified design of the device according to the invention whereby the device instead of the self locking support legs which are displaceable in slides, is equipped with hinged legs 18, 19, which can be folded down individually by means of hydraulic pistons 20 into contact with the basis and be folded up respectively.
