BHL220K is large tonnage and largest bucket capacity wheeled excavator in China, the key components adopt imported international famous brands, powerful, stable and reliable, fully hydraulic, electric control. Equipped with Kawasaki main pump main valve, gear box and driving axle are all ZF brand, the engine is JAPAN MADE CUMMINS, 133KW/2000RPM,

1. Cooling and preheating system ensure the operating optimization and quick start; Engine and hydraulic parts are durable in use.

2. Engine and hydraulic system are reachable and convenient for maintenance.

3. Centralized electronic control box facilitating the replacement of the air filter assembly

4. Open the side cover, you can easily check and touch the air filter, such as key components of the electronic control box.

5. Efficient and energy saving hydraulic pump

6. Main pump with EPPR valve and main valve together and electrical control system actualize the match optimization of the engine output power and hydraulic pump absorbing power.

7. High-capacity fuel tank and hydraulic fuel tank ensure continuous Operation and meet the requirements for heat dissipation.

8. Battery easily reachable, Battery located in the front of the excavator frame for easy check and maintenance

The driver cab is Homan-engineering design, it has the follow advantages:

1. Very good layouts, wide eyeshot, decrease the visual blind sector at max.

2. The driver seat is with safe belt, wide and comfortable, the high, low and front and back elevation angle are all adjustable, seat headrest can be adjustable too. The seat cab be adjusted forward and backward.

3. Equipped with high power air conditioner, and high class sound system, let you enjoy easy driving life.

4. The driving can floor is easily cleaned.

5. The driving cab is equipped with 6 shock pad supporting; greatly decrease the vibration of the driving cab.

6. The front window and the skylight of the driving cab can be open

7. Equipped with storage tank to store the food and drinks.

8. The instrument panel is showing multi information and tells you the working condition of the machine.

9. The inside air can be fresh by outer cycling and keep fresh air inside.

10. The air cooling exit located in the left and right side on the back and also in the front right side of the from window. The heating air exit located under the seat.

Hydraulic system, controlling system

1. Main hydraulic parts are originally imported, equipped with advanced controlling system.

2. The main loading flow rate controlling pump, the main valve combining with proportional pressure-reducing valve and computer controlling system, realizing the engine output power are matched with the absorbing power of the hydraulic pump, which decrease the power loss.

3. Automatic speed up and down system, through the computer controlling system the engine will perform the speed up and down function. Once selecting the speed auto idling function, the computer controlling system of the excavator will automatically regulate the engine speed according to the working condition( operating or not), thus decrease the oil consumption and less power loss,

4. Main pump flow controlling system: if not work there, the automatic speed up and down system of the engine will lower the speed, the main pump will decrease the flow and decrease the power consumption to the max.

5. Instantaneous power up system, through the computer controlling system performing secondary supercharging to the main overflow valves, thus improve the charge pressure of the main overflow valves and realizing the power increase by 10%, this function is specially suitable for provisional power charging to the excavator to perform some special work for example encountering very hard rocks.

6. Engine overheating Automatic protection system. The controlling system will monitor the Coolant temperatureof the engine cooling system, once the coolant temperature is over the setting temperature, the controller will automatically lower the engine revolution speed, and protect the engine, and make alarm.

7. Automatic machine warming system, the engine is started up, if the controlling system inspects and finds the coolant temperature is too low, the controlling system will automatically increase the revolution speed of the engine to warm the machine.

8. Independent pilot pump and brake pump guarantee good sensitivity and reliable braking ability.

Travel system:

The gear box and driving axle adopt international famous brand, high quality and reliable features, the rear axle is rigid connecting, the front axle( steering axle) adopt hinge connecting style and swing oil cylinder adjusting, which can efficiently improve the adhesive attraction during travelling. It has reliable braking ability; the gear box has automatic lubrication system.

Steering system

1. The steering devices and pipelines are good layout, easy for maintenance, big torque, feed circuit is smooth, equipped with non-reversing valve, which can realize fast slewing startup, and parking brake is precise

2. reliable structure and easy maintenance

3. the key hinge parts are all cast steel made, efficiently decrease the residual stresses

4. Upper vehicle frame and lower vehicle frame all adopt box style structure, it has very good welding performance, high strength steel plate, and guarantee the structure has very strong intensity and rigidity.

5. The bulldozer bucket has very good intensity, which greatly improve the whole machine stability.

6. Radiator (hydraulic fluid radiator, water cooling radiator, intercooler, and evaporator) installed on the radiator frame, via radiator frame connecting the platform, improve the stability of the radiator frame.

7. All the locks including drivers cab lock, all machine cover lock, toolbox lock use the same key

8. Opening the engine cover and left and right side door of the machine cover, the whole machine turn to be a open platform, convenient to inspect and touch engine, radiators, air filter, electric controller box, main pump and other main parts, convenient for the maintenance and repair.

9. Big capacity hydraulic oil tank and fuel tank can guarantee long time continuous work and heat radiation requirements.

10. The storage battery and main power supply switch located inside the toolbox, easy for the check and maintenance.

11. It has reserved the joint port for the legs and hydraulic hammer
