What do you think of Kato excavator？

Advantages and characteristics of Kato excavator

（1） Mitsubishi environment-friendly engine with high power output, low fuel consumption, low noise and Euro II emission standard is selected, which is wear-resistant, efficient and powerful.

1. Fuel saving

Fuel saving has become the consensus of more customers. The outstanding fuel saving performance of Mitsubishi engine is matched with its control system, which makes fuel saving even better. Account: This machine (Kato HD820R) consumes about 15-18L of fuel per hour, saving 3-5 L of diesel oil per hour compared with excavators of other brands of the same specification. We take 4L for calculation. If we work 2000h per year, then 4L × 2000h=8000L, calculated as per average yuan per liter of diesel, then yuan × 80000L=60000 pieces.

2. Unique engine intake system

The air entering the engine first enters a special device for preliminary dust removal, then enters the air filter for secondary filtration, and finally enters the engine. On the one hand, the air intake system makes the air entering the engine more pure, which is conducive to complete, thorough and fuel saving combustion; On the other hand, it also greatly extends the service life of the air filter element and saves the cost of accessories. This technology is very suitable for the working environment of excavators (high dust, high dust). At present, only a few excavators have this technology.

3. Mitsubishi #engines have a long history and excellent quality. They are widely used in excavators, cranes, cars, forklifts and other machinery of some brands (such as KOSCO excavators, KOSCO cranes). Mitsubishi engines are also used as power for some medium and high-end cars (such as Zhonghua, Mitsubishi, BYD, etc.) and some large #equipment in China. Mitsubishi Heavy Industries is also famous overseas.

4. Because #Mitsubishi engines have a high market share, the sources of spare parts are relatively abundant, easy to purchase and cheap, reducing the cost of use.

5. Mitsubishi engine is the best proof of fuel economy and high quality.

(1) In the CCTV authoritative automobile fuel saving contest, Lancer and Lingshuai cars with Mitsubishi engines won the first and second place.

(2) A Chinese car equipped with Mitsubishi engines was exported to Germany, becoming the largest order for Chinese car exports. Mitsubishi engine goes to the hometown of Mercedes Benz and BMW to "compete", and its quality is self-evident.

（2） The advanced APC (Automatic Power Control) system is transplanted from years of mature experience of Kato Crane, which is reliable, practical and perfect.

1. The control of automatic output power can make the hydraulic pump operate in the best state, and control the engine according to different loads, so that it has the most economic output. (As much force is used for excavation, the engine will be used as much force)

2. The self diagnosis function is complete and perfect.

Every time the startup switch key is turned to the "ON" position, 10 important items will be detected one by one, and "Checking!" will be played To start the self diagnosis function. The 10 important items to be tested are: insufficient engine coolant alarm; The engine coolant is overheated; The engine oil filter element is blocked, and the engine oil pressure is abnormal; Engine air filter element is blocked; Insufficient fuel remaining alarm; Alarm for abnormal hydraulic oil temperature; The filter element of hydraulic oil filter is blocked; Insufficient battery charge; APC system is abnormal. The two items of insufficient coolant alarm and overheating coolant monitor the working condition of the engine cooling system. The oil filter element is blocked and the engine oil pressure is abnormal. The two items monitor the working condition of the engine lubrication system. The working condition is very important for the normal operation of the engine. The project that the filter element of air filter is blocked has more practical significance for excavators that often work in high dust environment. If there is no such item, the air filter element is blocked, which will directly lead to insufficient engine power and increased fuel consumption during operation. The alarm of insufficient fuel surplus is also very practical. If the fuel gauge is inaccurate or fails without this item, once the fuel is exhausted and the air is inhaled during use, the air in the fuel supply system also needs to be discharged after adding fuel, which is a waste of time and more troublesome. The item of abnormal hydraulic oil temperature alarm (lamp and display screen) is also very important, because for full hydraulic excavator, too low or too high hydraulic oil temperature will directly affect the normal operation and life of the hydraulic system. The temperature of hydraulic oil is too low, which may cause the action of hydraulic related mechanisms to lag, slow, or even malfunction; Excessive temperature of hydraulic oil will greatly shorten the service life of relevant parts of hydraulic system, and also increase the possibility of leakage. Once the filter element of the hydraulic oil filter is blocked, the operator can be timely reminded to replace the filter element to ensure the cleanness of the hydraulic oil. It is reported that 70% of the hydraulic system failures are caused by factors such as dirt and impurities in the hydraulic oil. The project of insufficient battery charge is common to excavators.

In a word, the self diagnosis function is just right in terms of project selection and quantity.

3. Real time monitoring of excavator operation.

The combination monitor and multi-function display screen are important components of the APC system. They are installed on the control panel of the cab. They not only have language, text, symbols (international or customary), but also sound and light (alarm light is lit or flashing) alarms, which are very eye-catching.

Example:

(1) If the engine coolant decreases below the specified amount, a picture will appear on the display screen and the alarm lamp will turn on. This alarm message is displayed until the specified amount of coolant is increased by refilling.

(2) When the oil pressure becomes abnormal during the engine operation, the screen will appear again. When this screen appears, the buzzer starts to beep, the alarm light starts to flash, and "The oil pressure of the engine is abnormal, please stop the engine!" will also be played And the buzzer keeps beeping until the engine stops rotating.

It is easy to see from the above two examples that according to the urgency of the alarm content, the APC system of Kato excavator adopts different alarm methods to draw the attention of the operator, or even let the operator take measures immediately. Otherwise, the alarm will continue. The monitor display screen can display various information about the engine condition and other information If the APC (Automatic Output Power Control) system and monitor have no abnormal phenomena and there is no alarm information to be displayed, the "OK" qualified screen will be displayed.

4. The automatic warming function can better protect the engine.

When the system detects that the temperature of the coolant is too low, it will automatically increase the number of engine revolutions, set the required warm-up operation time, and display the remaining automatic warm-up operation time. For example, when the engine needs to be warmed up automatically, the engine will automatically enter the warm up operation state (medium speed), and the screen will appear on the display, showing that the remaining time until the warm up operation is completed is 5min15s. The automatic warming function is convenient, practical and intuitive, and is more suitable for protecting the engine in cold seasons or regions.

5. Three hardware tailored for fuel economy

(1) Controlled by the computer, the torque of the engine is always in the best match with the fuel supply of the #hydraulic pump.

(2) The setting of economic operation mode can make the engine speed be set to the speed that can save the most fuel.

(3) The combination of automatic deceleration mechanism and fast throttle switch greatly reduces fuel consumption. The automatic speed reduction function means that when the operating lever is pulled back to the neutral position, the engine will automatically reduce to the medium speed. The fast throttle switch allows the engine to switch freely between idle speed and preset revolutions.

6. The APC system is constantly pursuing perfection, showing itself incisively and vividly from the details.
