Background of the Invention The work machines that operate on tracks are generally very slow and, consequently, transfers even at a very short distance from such machines are preferably covered using separate carts Ref. 031383 or wheel systems mounted on the work machine. Such a last type of apparatus is known, for example, from GB Patent Publication No. 1,044,074. In the apparatus described in GB Patent Publication No. 1,044,074, a work machine is secured to a wheel system, whereby the chassis of the work machine must be equipped with separate coupling elements, which can lead to higher costs. The prior art apparatus involves disadvantages in terms of its use as well. The use is inconvenient and slow, because it requires special measures and, in addition, the operator of the work machine must step outside the cab of a work machine to fix the system of the wheels in place or, respectively, to release the wheel system. An object of the invention is to provide an apparatus, which can be fixed simply and quickly to a work machine and such apparatus does not need any modification to the work machine. According to the invention, this object has been achieved and an apparatus of the invention is characterized in that a work machine is adapted to be driven on a loading platform, the loading platform is provided with a protection to stop the advance of the machine working at a desired point on the loading platform and the protection is equipped so that, when the work machine is in contact with the protection, the mass of the work machine supply to the loading platform a forceful moment the loading platform so that it moves in a pivoting manner against the lower surface of a track of the working machine, and so that the loading platform is provided for each track with at least one holding element to eliminate a relative slip between the track Caterpillar and the loading platform and to fix the work machine against protection. When an apparatus of the invention is used, a work machine can be brought very quickly to a transfer condition or to an operating condition without forcing the driver to step out of the cab. It is also not necessary for the driver of a tractor vehicle to step out of his vehicle since, when an excavating machine is transferred, for example it is sufficient that the bucket of the excavating machine be clamped or braced against the platform of the tractor vehicle. The invention will now be described in greater detail with reference to the accompanying drawings, in which: Figure 1 is a side view, showing an apparatus of the invention in a condition, wherein the apparatus is ready to receive a working machine that is going to be driven on it.

Detailed description of the invention The apparatus, generally designated in the drawings with reference numeral 1, is proposed to transfer hinges of a work machine 3, especially an excavating machine, movable on tracks and provided with an excavating mechanism 2 or some other lifting mechanism. The apparatus 1 includes at least 2 wheels 4 spaced apart, mounted for free rotation and a loading platform 5 equipped therebetween. The loading platform 5 comprises a trough-like carriage, the floor of which is constituted by a number of beams 12 spaced apart, which are welded at the ends thereof securely to the sheets making up the side walls. for the loading platform 5, to which in turn is securely welded a rear wall similar to a plate and / or a beam 13 connecting the side walls 10 together in the upper portions thereof at the rear of the loading platform 5. The wheels 4 are mounted in a manner known per se on the side walls 10 of the loading platform 5. The fixing point is selected in such a way that, as a result of gravity, the loading platform 5 has its leading edge always exerting a pressure against the ground or floor, any time that the apparatus 1 remains freely in a condition unloaded on the ground (Figure 1), the working machine 3 it is derivable on the loading platform 5 in such a way that one end of the working machine will remain on the loading platform 5. The loading platform 5 is provided with a mechanical protection 7, which in the example of Figure 5 comprises a beam 13, to stop the advance of the work machine 3 at a desired point on the loading platform 5. The protection 7 is equipped in such a way that, when a work machine is in contact with the protection 7, the The mass of the work machine 3 supplies to the loading platform 5 a moment which forces the loading platform 5 to move pivotally against the external surface of a track 8 of the work machine 3. The loading platform 5 has a support surface which is provided for each track 8 with at least one fastening element 9 for eliminating a relative sliding between the track 8 and the loading platform 5 and for fixing the working machine 3 The protection 7. In the example of Figure 5, the fastening element 9 included in the loading platform 5 is constituted by a protrusion, which extends outside the support surface of the loading platform 5 and designed to correspond with a respective clamping element 11, included in the track 8. Naturally, the clamping element 9 can also be constituted by a recess, in which the respective clamping element of the track is retained and prevents a relative sliding between the track. caterpillar 8 and the loading platform 5. Depending on the weight and size of the transferable work machine 3, the apparatus 1 of the invention can be designed as shown in Figure 4, with both caterpillars 8 of the work machine 3 propped up in the same apparatus 1. Especially when it comes to heavy duty work machines 3, the exemplary embodiment shown in Figure 3 is more preferable, with each caterpillar 8 provided with its purpose 1. In this case, both pieces of the apparatus 1 are designed as independent units, separated from each other and only coupled together by the working machine 3. To prevent a convergence or divergence of the front wheels in the projection horizontally is developed between the wheels 4 of the separate parts of the apparatus 1, the loading platforms 5 have an internal width which is sized to be only slightly larger than the width of the track 8, whereby the loading platform 5 always it adjusts itself substantially in alignment with the track 8. In the solution of Figure 3, which uses two pieces of the apparatus 1, the side walls 10 of the loading platform 5 are adapted to diverge from each other as they progress upwards from the support surface of the loading platform 5. Accordingly, the apparatus 1 is incunable freely when transfers are made on uneven or uneven ground. In a preferred embodiment of the invention, the apparatus 1 is equipped with wheels 4 which are fixed automatically during the removal of a load outside the loading platform 5. Such braking mechanism ensures the immobilization of the apparatus 1 also on a sloping surface , thus facilitating the use of the apparatus 1. In an exemplary embodiment shown in Figures 5-7, the braking mechanism comprises a lever 4 articulated in the intermediate part to the external surface of a side wall of the loading platform 5. One of the legs, the lower one, of the lever 14, is pivotally equipped with a plate spring 15 or the like. In a discharged condition, the plate spring 15 is in the position shown with dashed and dotted lines in Figure 6, the other, the upper leg of the lever 14 leaning against the wheel 4 and blocking its rotation. To flex the spring 15, the loading platform 5 is provided with a flapper valve 16 pivotally hinged at its leading edge and depressed downwardly by the track 8 and, respectively, lifted upwards by the spring 15 at any time that the valve of hinge 16 is not subjected by a pressure application. The apparatus of the invention operates as follows. In the first condition shown in Figure 1, the work machine 3 is urged upward so that it rests on one or two pieces of the apparatus 1, all the way along the way until the caterpillar 8 collides with the permanent protection 7 included in the apparatus 1. After this, the track 8 can still slide slightly relative to the loading platform 5 until the track holds the holding element 9. At this point, the apparatus 1 and the working machine 3 are completely fixed each. Following this, the digging mechanism 2 of the work machine 3 is rotated from the position of Figure 1 to 180 ° around the vertical axis, thereby carrying the digging mechanism 2 over the bed of the tractor vehicle load. 6 and lifting the track 8 of the work machine 3 off the ground by means of the digging mechanism 2, after which the work machine 3 is ready for a transfer. If necessary, the work machine 3 can be used for the braking action by adjusting the digging mechanism 2 in such a way that the tracks 8 touch the ground at the front end of the work machine 3.
