Product Description:

1,Hydraulic system provide perfect power and accurate control to ensure continuous digging operation.

Main components, such as pump, valve, are manufactured by international top brand enterprises.

There is an open hydraulic system with Tri pump & Tri circuits, controlled by load sensing system and limit power to ensure higher efficiency and productivity at the lower est hydraulic loss. Reasonable power distribution and double pumps with crossover power control system can reduce circulation time under multiaction operation and promote productivity.

Swing secondary pressure control for better starting and braking pressure so as to ensure fast and stable swing operation.

Hydraulic hose, connection: world famous brand with excellent performance ensure better reliability for operation in mine.

High efficiency features:

Starting with zero displacement with better starting load and starting performance

Technique with minimum flow control at neutral position for best energy saving and economical efficiency

Technique with pressure cut-off to provide better system protection

Control of constant power of single pump, limited power of three pumps for reasonable distribution of engine power

Confluence of three pumps for combined movements and increasing of operating efficiency

Logic valve control for automatic straight traveling, automatic release of swing brake

Confluence of two pumps for increasing operating efficiency

2,Power system(Unique power-driven technology in China)

Electromotor

Clean energy: zero-displacement, environmental friendly

Low cost: compare to diesel engine, the electromotor is more economical

Maintenance free: lower operating cost and easy maintenance

Separate hyd-oil cooler with better cooling effect and easy maintenance

3,Welding&casting structure for working attachment

Adopt international top brand cylinder seal for better sealing property

Working attachment pins are made of special wearresistant alloy, hardening and chroming treated for getting high strength and long circle life

4,Automatic central ludricating sestem

Top brand automatic central lubrication at setting time interval, for specified quantity and at all lubrication points. which results in saving of manual daily maintenance, reduced manpower and increased productivity

5,Classified esign & manufacture based on working condition

Special design & manufacturing of bucket, undercarriage, working attachment and other structure parts based on different working condition; customizing design on power unit, hydraulic system, oil products and electrical system to make our products suitable for all kinds of adverse circumstance

Working attachments such as breaker, cultivators, quick-change connector can be equipped to meet different working requirements

Q:What are the manufacturers of excavators in Shandong?
Shandong excavator production manufacturers a lot of ah, like Komatsu, leiwo, temporary workers, mountain reconstruction machine, heavy truck excavator, sea Takeuchi, hunter, too much.
Q:Excavator slewing support which good?
Excavator slewing support which good? For medium and large slewing bearing 70%, Shenzhen Dazhong Slewing Bearing Co. Ltd is located in Shenzhen, the Pearl River Delta on the east coast, near Hongkong, is an important international air hub and foreign trade port city.
Q:How long does it take to learn how to start an excavator? Do you learn it in two months?
Find a master to take you, schools are deceptive, the whole class dozens of students, one person on the train 5 minutes, all TM pinch table count, skilled; 7 thousand and 8 thousand small meaning, by hour count money, technology is good, an hour 100 fast. A month closed eyes 5000 hands, but the premise is that a good boss, looking for the master, it is best to find their own excavators. I have a master, he did not hand up how I love dearly, I learned more than 1 months, the average daily bus 2 to 3 hours, is the actual combat, do my master's work, I do not want my master in the estimation of dry, fine, but also for 3 months, and the society skilled.
Q:What does "200" in Komatsu 200 mean?
The quality of the vehicle itself is 20 tons
Q:Dragon excavator 150 price
320DL advantages: similar models of the largest mining, durability, stability of the whole car, although high prices, but cost-effective. Disadvantages: large fuel consumption, short arm, resulting in some work can not be a molding, waste of time.
Q:The reason why the excavator holds down the engine is 150
[cause of trouble]1 hydraulic large pump failure2 excavator two valve problems3 hydraulic pump regulator variable chaos will also choke machine flameout failureFourIs the confluence valve of the solenoid valve blocked?5 hydraulic oil will also be more excavators hold machine flameout failureSixIf the fuel supply is poor, check whether the oil pipe is blocked or leaking[corresponding cause of failure]1 there is a problem with the circuitTwoCheck the wood and see if it's blocked. If you don't see it, get into the system3 there's something wrong with the engine4 there is water in the fuel lineFiveIf the air enters the fuel pipe, the excavator will stop and stall6, the gas supply is poor, causing the engine to stall7, the power of the engine is insufficient to achieve the power required by the hydraulic pumpEightThe hydraulic part has the stem to clamp, also can the excavator hold down the engine to extinguish the faultNineValve stem movement is not smooth, resulting in hydraulic power is greater than the output power of the engine, so the engine will stall[supplement]Corresponding troubleshooting:1., although you said that the inspection is no problem, but still suggested from the most basic fuel road cleaning, replace all filter elements, began to check. The diesel pump is removed from the oil line to see if the injection length can reach about 6~7cm.2. small arm and walk, mainly pump 2 oil supply, check the main pump cleaning 2 of the regulator.3. choke 90% is fuel road failure, it is best to carefully check the oil circuit to confirm that there is no leakage of space, such as pipe joint seal damage, filter is not in place, oil-water separator, water supply cover is not tightened, etc.. Direct connection with fuel tank test can be used.
Q:Is it a lie to hire 5000 to 8000 of the company's excavator and forklift drivers?
Look at which company and polish your eyes when you apply for it!
Q:Who can tell me about Doosan and Sunward Intelligent excavator which good? What are the advantages and disadvantages?
Doosan accessories cheap, only a small sunward no large excavator digging machine
Q:Excavator standard
(7) GB, 25684.5-2010, safety of earth moving machinery, fifth parts: requirements for hydraulic excavatorsAmong them, GB/T 7586-2008 and GB/T 9139-2008 are the main specifications of excavator performance, and GB 25684.1 and GB 25684.5 are mandatory standards for excavator safety.
Q:What should we pay attention to when purchasing excavators?
Excavators should pay attention to the chassis, hydraulic systems, walking systems, walking systems of steel (especially rail training and bucket teeth) is normal.Open the engine cover and check the exhaust pipe for signs of smoke. You can pull out the dipstick and check whether there is smoke. Too many usually illustrate the need to replace the piston rings of smoke, and may soon have to overhaul the engine also includes basic inspection and check the radiator and engine oil liquid, the corrosion degree of the engine and check the battery, check around there is no obvious leakage.Excavator, also called excavating machinery, is a kind of earthmoving machine that uses bucket to excavate material that is higher than or lower than the machine surface and is loaded into transportation vehicle or unloaded to the stacker. Excavators are mainly made of soil, coal, sediment, and soil and rocks that have been pre - loosened. From the development of engineering machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are operation weight (quality), engine power and bucket bucket capacity.
