运输槽主要由运输槽、抬槽油缸、主传动部分、刮板链、主动链轮、从动链轮和输送液压马达等部件组成。

槽体内衬有进口耐磨板，刮板和主（从）动链轮是用高强度耐磨合金钢制造。控制抬槽油缸伸缩可使运输槽升降，以分别满足工作或行走时的需要。启动液压马达正转可驱动刮板链把料石从料口运送到运输槽尾部卸载，在正常工作情况下，运输槽液压马达绝不可反转。

Tub is lined with a imported wear plate, scraper and main (from) dynamic chain wheel is made of high strength wear resistant alloy steel. Control lift slot can make transport pan lifting oil cylinder telescopic, to meet the needs of the work or walking, respectively. Start the hydraulic motor is turned to drive scraper chain stone from the mouth to the material conveying trough rear unload, under normal working condition, transport pan never reversible hydraulic motor.

履带行走总成主要由履带架体、驱动链轮、导向轮、支重轮、托轮块、链轨节、履带板、缓冲弹簧、张紧油缸、 行走减速箱和行走液压马达等零部件组成。

本总成的功能一是行驶，二是铲取料石。启动液压马达经过行走减速箱减速、驱动链轮带动履带运转。导向轮支承链轨节并引导履带正确卷绕防止履带横向滑脱。支重轮用来将机体的重量传递至履带上，并使机体沿导轨节运动，它还用来夹持履带，使其不横向滑脱，在转向时，迫使履带在地面上横向滑移。

he function of the assembly is a driving, 2 it is to shovel stone material. Start the motor after walking reducer reducer, drive sprocket drive crawler running. Guide wheel bearing caterpillar track section and guide track right winding prevent track horizontal slip. Roller is used to transfer the weight of the body to the track, and make the body movement along the guide rail section, it is also used for clamping the treads, make its not horizontal slippage, in turn, the forced track lateral sliding on the ground.

机架体主要使整机的各大部件联系在一起，并提供了司机室和各液压操纵元件的安装空间。

履带梁与机架通过高强度螺栓及平键组成可拆卸式联接，机架中部铰接运输槽、机架两侧装油箱总成、电机油泵总成、散热器、电控箱、座椅、司机室等部件，机架底部装牵引杆。

Track beam and frame by high strength bolt and flat key removable type connection, hinged frame central conveying trough and frame on both sides of the oil tank assembly, motor oil pump assembly, radiator, electric cabinet, chairs, cab parts, such as traction rod at the bottom of the racks.

电机油泵总成由电动机、双联柱塞泵、双联齿轮泵和联轴器等零部件组成，其中排量大的齿轮泵是专供 散热器油马达的动力源，排量小的齿轮泵专供先导用。

双联柱塞泵提供反铲机构、输送刮板链和履带行走的液压动力。

Double piston pump providing a backhoe, transmission scraper chain and crawler walking hydraulic power.

液压操作系统主要由四联阀、五联换向阀、单向阀、液压泵、液压油缸、液压马达、吸油滤油器、回油滤油 器、液压油风冷却装置、测压装置和手动先导阀、踏板式先导阀等液压元件组成。

以上元件经油管连接大臂、小臂、转臂、铲斗、左行走、右行走、左输送马达、右输送马达、抬槽共九条主油路和大臂液控、小臂液控、铲斗液控、回转液控、左行走液控、右行走液控共六条先导控制油路。

Above components by the tubing connection big arm, forearm, revolving arm, bucket, left to walk conveyor motor, right, left or right conveyor motor, carried a total of nine main lines and large arm hydraulic control, lower fluid control, bucket hydraulic control, walking hydraulic controlled rotary fluid control, left or right walking hydraulic control a total of six pilot control hydraulic system.
