apital construction, road maintainance„ etc. this model’s shape is bigger, the flexibility is worse, generally it hard to adapt the work of narrow and small place. SECOND: local present condition and development trend of loader digger, local technique condition At present in our country the enterprises producing the loader diggers are more than 10 hours, mainly is SHANDONG mechanical engineering, YANTAI mechanical engineering, LIAOLINGCHAOYANG mechanical engineering, LIUZHOU mechanical engineering, XIAMEN mechanical engineering, XUZHOU mechanical engineering, etc.. Currently the product’s year yield is about the history of our small scaled and multifunction loader digger, we can see that our machine has been dropping behind, its development speed is slow. Our country just started to design it by ourselves at the beginning of 70’s in last century, first the BEIJING building mechanical engineering developed successfully W Z 2 A and W Z 2hudraulic pressure loader digger, the YANTAL mechanical engineering manufactures ZW2Aand WZ2B hydraulic loader digger successfully in 1987,After that the FUJIAN mechanical engineering、 SHANDONG GUANGRAO hydraulic pressure engineering develop the loader diggers of WZ25,DFH904WZ,T55Z/W025 respectively. The LIUZHOU excavate loading、 Liuzhou Project Mechanical Limited liability pany developed WZ3025 and WZ2520 loader diggers respectively in july,2020,the SHANDONG Project Mechanical Limited liability pany successfully developed WZ3025 loader digger. 7 The products produced by the following manufacturers are mainly representing the technique level of domestic loader digger. ① the WZ3025 loader digger of CHANGLIN: the engine system adopts ins turbine pressurization engine . the rated output is 63 kNs ,the tap accords with European standard .The turn round for standard truck(front axle)is nondriven swing axle, the bearings adopt imported pieces .Choose to use imported driving axle(back axle)kitted to loader digger. Having nonmaintenance wet brake, which greatly raise the safety and the credibility of the truck belt difference speed padlock raises the draw bar performance of the whole truck .The standard truck driven by twowheel ,can be equipped with a fourwheel drive according to the customer’ demand .The hydraulic system adopts efficient gear pump system, the main parts such as pump, selector valve and redirector, all choose foreign wellknown panies’ products. ② the WZ2520 of YANTAL Project Mechanical Limited liability pany:WZ2520 loader digger takes loading machine for main part, with the head refitted to multipurpose bucket, the back end added excavation device.. The 904WZ loader digger of one drag DONGFANG red is based on the LF90 tractor whose technique is brought from Italian Fiat, with the corollary design of the agriculture engineering machine of various functions. ③ The WZ3025 if LIUZHOU Excavation car loader factory :The LIUZHOU Excavation car loader factory’s product of WZ3025 loader digger and the WZ3025 loader digger of LIUZHOU engineering machinery incorporated pany , all are new products based on the CAT technique and bine with our craftsmanship. these two models all adopt special bedrock, adopt the technology of the load telesthesia control as the same as the CAT pany .As these two models adopt variable system ,so they have higher request to cleanness and reliability of system. ④ the LIUZHOU AOLIU machine machinery incorporated pany series of loader diggers of HACH995 Engine: provided with the sophisticated turbo pressurization diesel engine, the rated output reaches to 95horsepowers, reaching to the torsional force of 384 mN at the rotate speed of 1500ture/the minute. The core parts adopt the imported famous brand product in the world , the credibility is higher. All new external appearance is pleasing to eyes, the cab room is relatively large。 the standard disposal of 4 in 1 bucket makes the machine have more multifunction。
