Description: FRAME FOR MATERIAL -HANDLING EQUIPMENT AND A MATERIAL-HANDLING EQUIPMENT INCLUDING THIS TYPE OF FRAME The invention relates to frame for material-hand ing vehicle and material-handl ng vehicle including this frame, and used especially in the engine-driven lift trucks. Well known is a frame for material-handling vehicle, consiting of longitudinal sheet beams, positioned parallel to each other, ending in its front end with brackets with holes for mounting a lifting equipment. iNear the bracket ends and under the longitudinal beams are welded perpendicularly to the longitudinal beams supports for mounting the drive axle. The longitudinal beams are rigidly connected by a front, intermediate and rear transverse beams. The intermediate and rear transverse beams have openings in their middle lower part for mounting the steering axle. On the inner side of the longitudinal beams are welded brackets for mounting the engine. On the outer side of the longitudinal beams are welded perpendicularly and connected to each other front mudguard, rib and rear mudguard. A roof construction is welded towards the upper part of the longitudinal beams and towards the front transverse beam. Well known is a material-hand!ing vehicle including the above mentioned frame ant mounted to the above mentioned frame drive and steering axle, engine, transmission and counterweight. At the inner side of the frame in the engine space are mounted fluid tanks. At the front area of the roof construction is mounted rigidly front shield, and at the rear part is mounted rigidly rear shield, to which is mounted a seat and lointly connected an overengine cover. The disadvantages of the frame for material-handling vehicle are its bad technological opportunity for production, unrationaly situation of the different elements. The frame is not universal for mounting of different drive and steering axles, as well of lifting equipments with different mounting dimensions and outer view, because a general change of the separate basic elements or the whole frame to match the requirements of the different versions. This worsens the possibility for a greater variaty of lifting capabilities and wheel bases of the material-handling vehicle with minimum changes of the frame. At the same time the frame is a part of the outer view of the material-handling vehicle. The mounting and dismountling process as well the servicing process of the vehicle units is quite difficult, because of the unproper mounting of the roof construction and the bad functionality of the basic frame elements. All these disadvantages raise the production prises of the frame and the material-handling vehicle, as well the expences for servicing and repair. The disadvantages of the material-handling vehicle are its bad technological opportunity for production, difficult servicing,, painting, because of the rigidly mounted front and rear shield, and roof construction. The fluid tanks, situated in the engine area, are with worsened efficiency, because of the engine temperature. As a result of the frame construction the vehicle is limited about the possibility for using different drive and steering axle, lifting equipment and wheel base matching the different lifting capacities. The outer view of the vehicle depends on the frame. Production and servicing opportunities are quite expensive. Task of the invention is to provide frame for material-handling vehicle, that gives the opportunity for good technological opportunities for production, servicing and repair, universal about the possibility of mounting different drive and steering axles, lifting equipments, engines, transmissions, wheel bases and outer view of the material-handling vehicle, and at the same time with reduced production expences. The material-hand!ing vehicle including that frame should have good technological opportunity for production, servicind and repair, to be multy-variant about the possibility of mounting different drive and steering axles, lifting equipments, transmissions, wheel bases, to assure the possibility for painting of the unit forming the outer view of the maqterial handling vehicles separatly, to decrease the harmful influence of the engine temperature over the fluids and possibility for different outer views of the material-handling vehicle and high painting capabilities. The solution is a frame for material-handling vehicle consisting of two parallel longitudinal sheet beams, connected by means of front, intermediate and rear transverse beams. On the outer side are welded perpendicularly to the beams welded in advance front mudguard, rib and rear mudguard. At the inner side are welded brackets. According to the invention on the front transverse beam are rigidly mounted at suitable distance two brackets for mounting both the drive axle and the lifting equipment. The intermediate and rear beams are with concave form. At the middle part of these beams is mounted rirgidly unmovable support to which in a suitable way are mounted rigidly eyes for mounting the steering axle. The front and rear mudguards have holes for mounting the roof construction. The material-hand!ing vehicle includes the former mentioned frame, tounted to it front and steering axle, lifting equipment, engine, transmission, roof construction with front shield, fluid tanks, overhead cover with jointly connected to in little cover with the help of an axle, rigitly mounted to the counterweight. A seat is dismountably connected to the overengine cover. At the front part of the roof construction is attached by means of dismountable joints a sheat, to the lower part of which is joitly mounted front cover. At both sides of the frame are welded eyes, to which by means of dismountable connections are mounted cover, forming together with the frame space for mounting the fluid tanks. Advantage of the frame for material-hand!ing vehicle according to the invention is the fact that it gives the opportunity for the basic part of the frame, consisting of longitudinal beams, transverse beams and mudguards to be manufactured separately and undependably from the dimensions, for mounting the drive and steering axle, lifting equipment, engine, transmission. The brackets for moumting the drive axle and lifting equipment, the eyes for mounting the steering axle, as well the brackets for mounting the engine and the transmission are produced separately and are independant of the frame. The two groups of elements increase greatly the possibility for mounting different units as well the variaty of lifting capacities and wheel bases of the material-handling vehicle. Improves the technological opportunities for production of the frame, increases productivity and decreases expences. Another advantages of the invention are the possibility for separate production of frame and roof construction, and in that way improvement of the assembly servicind and repair operations and variaty of outer views. Advantage of the material-handling vehicle is the easy access to all unit and systems. Thanks to the dismountable joint between the front shield and the roof construction amd the use of joint connection between the shield and the front cover, it is possible to get an easy access to the hydraulic elements, mounted on the front side of the shield. All parts of the material-handling vehicle that form the outer view of the vehicle are dismountable, which assures good varnishing prior to assembly. The frame is an unvisible element of the outer view of the material-handling vehicle. The additionally mounted side covers assure two more advantages - in the cavity between them and the frame are situated tanks for fluids, which are in this way protected from the engine heat by the frame, which acts like a thermal shield. By changing the overengine cover ant the side covers it is easily possible to change the outer view of the material-handling vehicle as a whole. Fig. 1 and 2 are an example drawing of the frame for material-handling vehicle. The frame for material-handling vehicle consists of parallel longitudinal sheet beams 1, connected rigidly with front transverse beam 2, intermediate concave beam 3 and rear concave beam 4. At the front part of the beam are rigidly mounted at suitable distance from each other two combined brackets 5 for mounting the drive axle 16 and lifting equipment 17. Towards the middle part of the concave beams 3 and 4 is rigidly mounted support 6, connected rigidly along its longitudinal axis with plate 7. Underneath on plate 7 in a suitable way in accordance with with the mounting dimensions of the steering axle 18 are fixed eyes 8. On the inner side of longitudinal beams 1 are rigidly mounted bracket 9 for the engine. On the outer side of longitudinal beams 1 are mounted rigidly and perpendicularly to the beams and to each other front mudguard 10, rib 11 and rear mudguard 12. On the upper sides of front mudguards 10 andd rear mudguards 12 are made holes 13 and 14 for mounting the roof construction. An example execution of the material-handling vehicle is shown on fig. 3 like an axonometric view. The material-hand!ing vehicle consist of a frame 15 and mounted to it drive axle 16, steering axle 18, lifting equipment 17, engine-transmission assembly 19, counterweight 20, roof construction 21; by the help of dismountable joit to it is connected shield 22 with jointly connected front cover 23. The overengine cover 24 and cover 25 are jointly connected to each other by means, of axle 26, which is fixed to the counterweight by means of a dismountable joint. Eyes 27 are rigidly connectd to frame 15 and are used to connect side covers 28 to the frame. In the cavity between frame 15 and covers 28 are mounted fluid tanks 29. On the upper side of engine cover 24 by means of dismountable connection is fixed seat 30. The use of the frame in the lift truck industry is done in the following way. The frame is worked out without brackets 5 for drive axle 16 and lifting equipment 17, without engine bracket 9 and eyes 8 for steering axle 18. Brackets 5 are produced separately and according to the requirements of drive axle 16 and lifting equipment 17. The brackets for mounting the engine 9 depend on the engine type 19. The design of eyes 8 depends on steering axle 18 mounting dimensions. A set of different types of brackets 5, 8 and 9, and only one frame could suit all lifting capacities and wheel base of a whole family of lift trucks. In accordance of the type of the lifting equipment different types of combined brackets 5,8 and 9 could be rigidly mounted to the frame. The material-hand!ing vehicle is assembled and used in the following way. After the assembly to frame 15 of drive axle 16 and steering axle 18, engine-transmission assembly 19, counterweight 20, lifting equipment 17 and roof construction 21; towards the front part of the roof construction 17 is mounted with dismountable joint shield 22 and the jointly connected to it front cover 23. The shield is a base for mounting the hydraulic elements of the truck. The assembly is concluded with the mounting of engine cover 24 with seat 30 and cover 25, that are jointly connected to each other with an axle, that is fixed to the counterweight. The side covers 28 are connected to eyes 27.
