Performance Characteristics
⊙The CAT 336D lengthen chassis ,which has the characteristic of super stablilty , is fixed on the XR245C. The chassis with high strength adopts the hydraulic telescopic caterpillar which is convenient for transport and with super function of travel .Adopts the C9HHP 261Kw@1800 RPM, EPA Tire Ⅲ engine ,and meets the requirements of Europe and North America etc.
⊙The oil cooler and the radiators are fixed side by side behind the mid cooler. The cooling effect is well-The fun is driver) by hydraulic motor and the speed of the fun is controlled by plunger pump. The noise meets the requirement of noise control. It is much more quiet and protect environment.
⊙The main hydraulic system adopts the negative flow control, and adopts the main power control and limit power control together which can increase the system efficiency and make the most of the engine power{he assistant system adopts the load sensitive control system. The power output can match the operating conditions well, that realize the flow can be supplied according to need and the efficiency of the driven system is increased to the highest point.
⊙The rotary head is operated by a press or draw hydraulic cylinder. The drilling hydraulic motor, top spring absorber and the flange that used to open the bucket are all fixed on the rotary head. The drive case that fit to frictional or internal lock drill pipe and pilot bearing of drill pipe with bearing are equipped.
⊙The intelligent control technique, CANBUS technique and the virtual technique are all applied on the machine. The machine adopts the controller with super reliability and the color liquid crystal display. The chinese man-machine interface in the display can be operated easily and easy for inspection. It can display the perpendicularity of the mast and the depth of the hole and it also can detect the display record, fault record, and the input/output signal of on-line debugging automatically. Also it can display all kinds of warning information such as the mast limit position, amplitude limit position and the main and the assistant winch limit position, the filter warning, and the prompt for the maintenance etc.
