Cab Part
Reasonable layout, the important control elements are arranged in a recent Department operator, while another suitable operating space and access, reduce operating power while reducing operator fatigue. Bright, to minimize the visual blind spot. Large, comfortable seat belt configurations; addition to the high, low, and before and after the elevation adjustable, the head is also on the lower adjustable; same seat before and after the two adjustable steering front and rear adjustable fully meet the needs of different body operator. Configure advanced power conditioning and sound system, in a tense work, relaxed and enjoy life. Easy to clean the cab floor. Advance commitments from the six cab vibration, reduce the cabin vibration.. To open the cab front window and skylight. Storage box to facilitate storage of food and beverages. Easy-to-read instrument panel can simultaneously read multiple messages, the equipment working conditions under control. Cab air circulation through the renewal of foreign air, keeping indoor air clean driving. Exports in the cold air after the operator head right and left sides and the front window on the right, hot air exports in the seat. -------------------------------------------------------------
- Hydraulic and electric control system -------------------------------------
Major international procurement of hydraulic components, with advanced electronic control system to maximize its function.
1. Negative flow control system, main pump, main valve combined with proportional pressure reducing valve and electrical control system to achieve the engine output power and pump absorption power, minimizing power loss.
2. Automatically increase (decrease) rate system, through the engine electronic control system can automatically increase (decrease) speed function. When you select automatic idle feature, electronic control system can excavator working conditions (with or without operation) automatically set the response time to adjust the engine speed, this can reduce fuel consumption and reduce power loss.
3. The main pump flow control system when there is no work, on the one hand because the engine automatically increase (decrease) speed system reduces speed, while the main pump will be reduced because of the negative flow system and flow, to minimize power consumption.
4. Transient increase power system through the electronic control system to achieve the primary relief valve on the second booster, which must increase the pressure relief valve in the open in order to achieve 10% power increase; that is particularly suitable for excavators require temporary additional force to achieve some special operating conditions such as Tu Yu hard rock.
5. Overheated the engine control system for automatic protection system has been monitoring the engine cooling system, coolant temperature, when the coolant temperature exceeds a set, the controller will automatically reduce the engine speed, to protect the engine, and alarm.
6. Automatically starts the engine warm-up system, the control system if the detected engine coolant temperature is too low, the control system will automatically increase launch speed and achieve the purpose of warm.
7. Separate pilot pump and the brake pump to ensure the operation of the sensitivity and reliability of braking and safety. --------------------------------
- Travel systems ------------------------------------------------------
Transmission and drive axle have selected internationally renowned brands, quality, performance is guaranteed. Rear axle rigid connection; before the bridge (to bridge) by articulated connections, fuel tank with a swing adjustment, in the process of moving to strengthen the adhesion; brake reliable performance. gearbox lubrication system automatically; road stalls, off-street stalls, trailer stalls ranging; reliable braking performance. walking motor automatic transmission, with a balance valve, enabling traffic shift. -----------------------
- Rotary System ------------------------------------------------------
Reasonable rotation system layout, piping to the natural, easy to maintain. Torque, smooth up the oil circuit, and with anti-reversing valve enables rotation starts fast, precise control of parking brake function. ----------------------------
- Vehicle reliability and maintainability of the structure ----------------------
The key point of working device hinged steel castings are used to effectively reduce the residual stress of these parts.
Under the frame on the frame and box structure are extensively used, supplemented by good welding performance, high strength steel plate, to ensure adequate structural strength and rigidity. Structural strength of a good blade unit can excavator digging operation greatly increased the stability of the time.
Radiator (oil dispersion, Water casual, cooler, evaporator) installed on the radiator support on the connection from the radiator support and platforms to improve the overall reliability of the radiator.
Cab door locks, all hood lock kit locks share the same keys, simple and natural.
Open the hood and hood left and right side of the door, the whole car has become an open platform; can easily check and hit the engine, radiator, air filter, electric control box, the main pump and other major components, easy to maintain, maintenance .
Large-capacity fuel tank and hydraulic tank ensures continuous maximum working hours and hydraulic system cooling requirements.
Batteries and power the main switch is located within the toolbox, easy inspection and maintenance.
Reserved for legs and hydraulic hammer interfaces.
