Q:The hourly fuel consumption and digging capacity of excavators 10
Hitachi 200-3 as an example:Fuel consumption about 12~15 liters per hour or so, mainly depends on the size of the excavator work intensity.The amount of excavation is 10 hours a day, about 1000 square meters (general dumping does not include loading and other special operations).
Q:What does the excavator pay attention to?
Six, pipelinesEach city has a complex underground pipe network, excavator working in urban areas need to pay special attention to mining, underground pipelines, ruptured or Waduan pipeline is very dangerous, but most did not see drawings of the underground pipe network, do not know the location and depth of pipeline, which requires the driver to pay special attention to in the work. Because the pipeline is mostly the excavator landfill, so we can also according to the experience of the pipeline position to do some estimation and judgment, is the general pipeline and road parallel to or in the roadbed or green belt, and a manhole cover, manhole cover will indicate the name of the pipeline, to a manhole cover line is pipeline. Usually a road is buried under a variety of pipelines, the deeper is the rain and sewage, mostly cement pipes used before, and now use bellows. Then some shallow is tap water and gas pipe, the tap water is very thick cast iron pipe, gas pipe is the appearance of a protective layer, and now the use of pe. A bit more shallow is power and communications, usually in the exterior protected by a PVC tube, with wires or cables. Including water, electricity and gas are very dangerous, if you Waduan defense military fiber optic cable is very serious consequences, excavation operations in urban areas must pay special attention to.
Q:Who knows all imported excavator brands?
The following has covered all the mainstream brands Caterpillar: American brands, old brands, independent production. (CAT) advantages: adequate strength, durability, strength, and not bad. Disadvantages: high price, high fuel consumption, short arm, small work range. Especially mine type models, large fuel consumption, after-sales service in general. 20T model: reference price: CAT320DGC 97-100W 320D 110-115W Komatsu: Japanese brand, excavator industry leader, the total cost-effective, independent production. (KOMATSU) advantages: better strength, strong and durable, low fuel consumption, hydraulic pressure is its strong point, the overall coordination is good, the speed is very fast, not easy to bad, good hedge, used car good shot. Disadvantages: high prices, accessories expensive. (Note: because of the domestic market share is very high, deputy plant parts, so it is relatively cheap) 20t models: PC200-8 97-100W PC200-8 hybrid reference price (earth preferred fuel consumption is 30% less than the average car) 110-118W Hitachi: Japanese brands, excavator sales are also very large, generally also can be assembled. (HITACH) has the advantages of mechanical matching, hydraulic system, flexible action, general value, durability, cost, fuel consumption, power, price 3-5 million cheaper than Komatsu.
Q:When did excavators first come out?.
In the current social construction, excavators are becoming more and more integrated with our daily life. The excavator is the earliest human or animal power for digging deep river dredger, bucket capacity is generally not more than 0.2~O.3 cubic meters. The first excavator manual has been developed for more than 130 years of history, has experienced a gradual development process of automatic hydraulic excavator driven by steam rotary bucket excavator to the internal combustion engine and electric drive rotary excavator, application of mechatronics technology during the. 2012-4-15 22:37:57 upload download attachment (7.39, KB)American Otis 1833~1836, the design and manufacture of the first steam engine, composite structure, semi rotary, rail mounted single bucket excavator, productivity is 35 cubic meters per hour, but because of poor economy without application. The improved steam shovel was formally produced in 1870s and applied to strip stripping. In 1880, the first semi - rotary steam shovel with tractors as the chassis appeared.From the early twentieth Century to the late 40s, excavators entered the stage of diversification of power and walking equipment.In 1910, there was the first motor driven single bucket excavator;In 1912, there was a full rotary single bucket excavator driven by gasoline engines and kerosene engines;In 1916, a single bucket excavator powered by diesel generators was produced;In 1924, diesel direct drives began to be used on single bucket excavators; crawler walking devices were introduced in 1910. With the development of the automobile industry, the tire walking device is widely used in small excavator.In 30s, a walking device appeared.Due to the application of hydraulic technology, a suspension excavator equipped with hydraulic backhoe was installed in the tractor in 1940s.
Q:Does the excavator include the off-site transportation of excavators?
Excluding off-site transportation, the Hebei is limited to this chapter in the major machinery, one safety, and off-site transportation charges
Q:Introduction of excavator
First, the definition of excavators, excavators, also known as mining machinery (excavating machinery), is digging with bucket mining materials above or below the surface of the machine, and loaded into the transport vehicle or dump to the stacker of earthmoving machinery. The main materials are 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, and excavator as one of the most important construction machinery models in engineering construction, the correct selection is also more important. Two, a brief history of excavator first hand excavator has been developed for more than 130 years of history, has experienced a gradual development process of automatic hydraulic excavator driven by steam rotary bucket excavator to the internal combustion engine and electric drive rotary excavator, application of mechatronics technology during the. The first hydraulic excavator was successfully invented in japan. Due to the application of hydraulic technology, 1940s has been installed in the tractor equipped with a backhoe hydraulic excavator suspension, in early 1950s, and have been developed in the mid towed rotary hydraulic excavators and crawler hydraulic excavator.
Q:How many hours does the excavator usually last?
Look at the life of the maintenance, the service life of various excavators will have a fixed range, for example, an excavator to dig the mountain, mining, heavy work, so no matter what brand is probably in 7 years would be scrapped, the so-called good quality that is nonsense, and good times, were at most for a year, so buy excavator want to make money do not buy luxury brands such as excavators, Carter Komatsu, and can choose the price at the end, practical such as Liugong, you can receive the cost within three years, and four years can be earned a Carter about one million to what time to recover the cost?
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:Are there any differences between backhoe and crawler hydraulic excavators?
There are differences and connections between backhoe and crawler hydraulic excavators:1. Crawler hydraulic excavators include backhoe crawler hydraulic excavators and shovel crawler hydraulic excavators;2. Backhoe includes backhoe crawler hydraulic excavator and backhoe wheel hydraulic excavator.The difference between the various excavators can be seen in the following figure.
Q:What are the loading skills of excavators? Just a few words!
This question can not be made clear in 32 words! It feels like you have to do some systematic training! I learned it at the school of engineering and machinery of Zhumadian City, Henan province! Feel this home is pretty good, 1, want to be loaded quickly, the first is to be loaded with. Not half shovel. If you think so, it's all a bucket, how much you dig and how much you dig. If you dig a little more than other people, you'll be less loaded with 1-2 shovels in a car, so you're not faster than others?.
