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, completing the change from loader to the excavator loader digger is mainly used for the highway construction and protect of the city and village, the electric cable build, electric power and airport engineering, municipal services construction, farmland irrigation construction, village residence construction, opening mountain to take stone and various small scaled and multi-function engineering machine, generally used in the small project after the completion of the big ones. FIRST: A CLASSIFICATION OF THE LOADERDIGGER The loader digger is so called “two favour” having two kinds of funcitions of lading and scooping out in the meantime. The classifications are as fallows ONE: from the structure According to the structure, loader diggers have two kinds of forms: one is with oblique tones move frame, the dinging device can be moved with side, which is easy to work in the special place, the center of gravity is lower when it transports. It is advantageous to loading and transporting. The weakness is: because of the restriction of the structure, the ground jack usually adopts vertical leg. The supporting point is within the wheel edge, the distance of the two supporting point is relatively small. While scooping the whole machine’s stability is bad. ( especially the scooping device moves to one side). The functional main point of this kind of machine is in the aspects of loading, producing more in Europe ; the excavation device of the latter can’t move to side, the whole excavation device can make 180皌urn-over through the rotary supporting, the ground jack is like the frog l
