【正文】 the domestic excavation car loader development should develop high grade, multipurpose, the multivarieties, the multispecification series product and strengthens the foundation part, the part production, Enhances the hydraulic pressure part in particular the quality Achieved in satisfies under the product reliable premise reduces the product cost, And enhances the product the postsale service level. 。the rear axle is the transmission, adopting the bipole deceleration structure .The Drive motor is equipped on the hull of the main decelerator, moved by spiral taper gear, the roundside decelerator is the plaary gear system, the stiffness of the whole structure is good ,output speed is 9 steady .Between the main decelerator and the effect of semi axle when the axle housing is working in the process of distortion .The Running system adopts the static hydraulic pressure transportation. The truck frame adopts a whole weld type structure, having the characteristics of good rigidity and great strength.. The ground jack is Htype vertical leg, connected with the truck frame into a integral .The drive of transmission adopts hydraulic pincer tray type ,the advantage of the hydraulic manipulation is celerity and reliability. Applies the brake in the vehicle for the drum central brake, manoeuvring mechanically. The antispade of the cab room is integral largewindow rollin structure ,which is beneficial for aeration and mindexpanding, convenient for operating, the rear driving tire adopts diameter lowpressure tire ,when running ,it can buffer vibration and ease vehicle to jolt, raining the fort of the pilot .Because the development of the loader digger in our country starts late ,pared with abroad we have a long distance to run, such as the range of product, functional parameter ,the credibility and aftersales service...etc. 2: Domestic excavation car loader petition enterprise and domestic trend of development At present the domestic excavation car loader petition enterprise and divides into: ① Export modeif :Sichuan road machine shop production multipurpose project machinery 80﹪ above all for sale abroad, moreover the sale is continuously very good moreover, Guilin Forestry machine shop produces the small marching excavation car loader specially, product major part exportation. ② Overseas enters, the domestic assembly: If Shanghai CASE 590580 series product. Overseas import domestic agent: if JCB 2CX/3CX/4CX。 adopting special frame of the loader digger. The cab room can be replaced respectively, associated with frame through five damping decouple devices the 8 hydraulic tank and burning tank also can be replaced ,and laid in low bit ,benefit in lowering the machine’s center of gravity ,exalting the stability ,and is suitable for fuel add and fixcheck on the ground. They also bee the part of stairs when ascending the truck. ⑤ The WZ3025 of TAIANSHI loading machinery incorporated pany: Motive system: This machine adopts the 4 B T 74 turbine pressurization engine, with the characteristics of tight structure ,great power, low oil consume, little noise ,work credibility and long life span etc. The hydraulic system: This machine adopts the original pump and manoeuvring valve of German LELISHI. The system adopts load telesthesia control technique, when the valve plug of the king valve is situated in meso position, the differential pressure that is produced by manoeuvring valve feedback to varable delivery pump, so as to reduce the output of the pump automatically, make the discharge nearly to zero。 5 EXCAVATES THE CAR LOADER DOMESTIC PRESENT SITUATION AND THE MARKET DEVELOPMENT ANALYSIS The loader digger is so called “two favour”. Because it has special structure, loads device being the head and the equipment for the excavation behind. in the workplace , you need to turn the chair, pleting the change from loader to the excavator loader digger is main
