Construction machineryHeavy Duty Backhoe Loader
The D-50L compact front end loader and backhoe provide superior digging, trenching, back-filling and material handling capability and can be used for many applications, including but not limited to General Construction, Demolitions and Excavations, Landscaping, Breaking Asphalt and Paving. Backhoes deliver the power and precise handling you need when operating in areas where using larger equipment is not practical.
Multifunctional backhoe loader performance is characterized by: backhoe loader chassis a chassis is the foundation of the whole machine, diesel engine and working devices are installed on it. The chassis consists of a rotating system, a traveling system, a rotating system and a braking system. Backhoe loader loading device The loading device mainly consists of bucket, moving arm, working cylinder and so on, which is used to shovel materials. The loading device is placed in the forefront of the machine. Excavating loader excavating loading a digging device at the rear end of the machine, mainly composed of excavating bucket, drawbar, bucket rod, movable arm, bucket cylinder, bucket rod cylinder, slewing body, slewing cylinder, outriggers and outrigger cylinders, etc., which is used to carry out the control of digging operations. The slewing body and hydraulic outriggers are installed on the rear frame. Backhoe loader hydraulic system a digging device and loading device using the same working pump, the principle is: from the hydraulic pump out of the hydraulic oil through the priority valve, all the way into the steering system, the other way through the two-link distribution valve directly to the seven-link distribution valve, and then back to the tank through the radiator. Operation of the two-link valve can realize the loading device lifting, lowering, collecting bucket, tipping bucket, unloading and other actions. The linkage of seven valves can realize the hydraulic outrigger expansion and contraction, slewing body rotation, digging device and the action of the additional device. Backhoe loader electrical system a mainly by the generator, starter motor, battery. Instrument panel, wire speed and other components, used to control the starter motor, generator and instrumentation, lighting
