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: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:How do excavators distinguish between positive and negative?
The left joystick, if it is front and rear control rotation, that is backhand, if it is left and right spin control, turn is forehand
Q:Modern excavator 220LC-5 detailed parameter 20
Just lift the arm slowly, if the other action is no problem, then that master is in your car speed problem, only to tune the pumpIf so, you can remove the big arm associated with the safety valve, commonly known as "gun", no need to change before cleaningIf the vehicle is slow if it is the big problem that the master pump was fast speed but the speed is inversely proportional to the load causes you to hold the car if the pump is no problem that the engine not load your pump if the engine is no problem that you lead to serious wear of pump leakage hold car the hydraulic pump is the inside of the cylinder piston disc what are very delicate wear will lead to slow my car(as is the same reason to drive gearbox speed express boring speed is slow. This is why a second start)
Q:What can an excavator do?
More, go, dig the ground, repair the slope, dig trenches, dig the floor, build roads, load cars, and so on...
Q:Method and steps of slope repair by excavator.
The slope is an inclined plane. Turn left and turn right | general dig one or more like groove, to make reference to the sample groove is generally a bucket width, by the excavation line to the excavation line, line connection, and then by the sample groove extended into a surface. In the second case, it is harder to cut from top to bottom. In the slope below the ground excavated roadbed. Turn left turn right | repair this slope is more complicated, many factors, such as irregular excavation line slope ratio (the ratio of height and width of the slope), table height etc..
Q:Origin of Volvo excavator
At the beginning of production, crawler excavator was mainly produced.In 2007, Volvo building equipment company completed the Chinese engineering machinery enterprises - Shandong Lingong Construction Machinery Co (Shandong Lingong) 70% equity investment. So most of the machines are Shandong Lingong production.
Q:What are the skills of an excavator?
Q:Use of excavators
(3) the quarry, tunnel, underground powerhouse and heap loading operation in the field of material; 4) excavation channel, canal and waterway dredging;
Q:How big is the digging bucket of Komatsu 200 excavator, what is its length, width and depth?
Baidu search Komatsu china"The first page is Komatsu official website, product center, which can look at the specifications of each vehicle configuration
Q:31 excavator 75 how much is it?
31 75 new machines in Sishiyierwan around. About two hundred thousand of second-hand excavator, excavator second-hand price according to the condition of the machine, the use of time, there are no major accidents and maintenance evaluation, suggestions of second-hand excavator, the risk of small, quick returns, but don't go to the market, you can go and see the two dragons and fishes jumbled together, large hand excavator market, such as Kunshan dig Xiang second-hand excavator market.
