Product Description:

We can design and produce excavator buckets for all brands, scientifically solve stress problem as different construction conditions and customer requirements, and have ability to ensure structural strength, use performance and product quality by selection of high-quality material, advanced computer-aided design and complete control over process welding quality. The specification ranges from 0.1m3 to 12m3.

By bucket type and material, there are common bucket, imitated original bucket, reinforced bucket and rock bucket, which are made from domestic high-tensile structural steel 16Mn (Q345B), in addition, the tooth plate and side edge board of reinforced bucket and rock bucket can be made from domestic high-quality wear-resistant steel NM360 and Sweden ultrahigh-strength wear-resistant steel HARDOX according to customer demands.

By function, there are ditching bucket, grid bucket, cleaning bucket, and tipping bucket, etc. The ditching bucket is suitable for ditching in different forms, and is featured by once forming, no finish and high work efficiency. The grid bucket is used to separate, excavate or salvage bulk materials excellently at a time, and is widely applicable to municipal administration, agriculture, forestry, water conservation and earthwork, and cleaning bucket and tipping bucket are suitable for finishing of slop and other planes and huge desilting and cleaning of riverway and ditches, and the tipping bucket can change the dip angle of cleaning bucket by the hydro-cylinder, which greatly improves work efficiency.

Q:What are the brands of excavators? What are the signs of each brand?
Imported brands: [US] CAT (Carter), CASE (Keith) [Japan] KOMATSU (Komatsu), HITACHI (Hitachi), KATO (Kato), SUMITOMO (Sumitomo), KOBELCO (Shen Gang). [] Korea DAEWOO (Da Yu), HYUNDAI (Modern), SAMSUNG (Samsung). [Sweden] VOLVO (Volvo). Domestic brands: Liugong, XCMG, Sany, Xiamen, Yuchai etc..
Q:31, 75 excavators
Carrying 8, forty-two, carrying 9, forty-four, the whole paragraph. So you must be careful when you buy 31 new machines. Because 312 mobile phones depreciate badly. A few days ago I went to the market to buy second-hand excavator Jincheng when Komatsu 60, saw a 13 year -9 2000 hours of work that only sold more than 20. No, I bought 10 years Komatsu 60-7 expensive. So it's better to add tens of thousands to buy Komatsu 60-7. Comparative hedge
Q:Construction units excavator access, what materials should be submitted to the supervision unit?
The construction organization design, a variety of special programs, pre construction permits, personnel readiness, the establishment of full-time management personnel qualification certificate, measurement and control instrument, audit personnel quality and technology management system and system.With the construction contract and the supplementary agreement signed by the parties (the construction need to be reported, but according to the site requirements, may also submit supervision units), qualification of construction units, safety production license, management system, construction organization design, various operator certificate copy of the emergency rescue plan, the main construction machinery and equipment remove / install aproval special safety construction scheme, material / re inspection, the progress report
Q:What are the main parts of the excavator structure?
The common excavator structure includes power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities, etc..In appearance, the excavator consists of three parts: the working device, the upper rotating platform and the walking mechanism. According to its structure and use, can be classified as: track, tire, walking, full hydraulic, semi hydraulic, full rotation, non full rotation, universal, special type, articulated, telescopic arm and other types.A work device is a device that performs the task of digging directly. The utility model is hinged by three parts, such as an arm, a bucket rod, a bucket, etc..
Q:What are the brands of excavators?
Komatsu, Doosan, Nagano, 31, Hitachi, Kaiyuan, rhino, diamond, Juli etc.
Q:What is the difference between a loader and an excavator?
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.Both are earthwork operations, excavators (commonly known as hook machine) bucket can be below the horizontal line. The bucket of the loader can only be above the horizontal line. The difference is that the two uses are different. Sometimes they can substitute for each other. There are many types. Under normal circumstances, a large number of materials on the horizontal surface are installed in the loader, and the utility model has the advantages of large bucket capacity, flexible movement, high loading efficiency and good economy. But the loading and excavating of materials under the horizontal plane can only be done by excavators.
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:What kind of industry does excavator belong to? What's your occupation?
Excavators belong to the construction machinery industry, excavators usually require excavators, driving license, of course, there is a master band, there is no evidence, the problem is not large.
Q:What about sunward excavator?
Sunward lost on domestic machines, small digging is fairly good in domestic sales, in the big dig on how.Cheapness。 Look, what price do you belong to?.At the end of the price to buy the country, yuchai. (cheap, no good)High price to buy 31 machines. (domestic sales first. Mainly after-sales service is good. The digging machine in the same tonnage configuration with Komatsu. Just like Hitachi. But the price is much lower than the bottom. Is the highest price of the machine) suggest to buy (a small earthquake in Japan nuclear leak is to buy 31 pump. The highest pump in 31 Chinese group)If you have money, you'll buy komatsu. Carter. No, I said. Is more than 90 years of digging machine brand)What stage do you think you belong to?. This place a lot of 31 excavator. Small to 55. to 460. after-sales really nothing to say.
Q:Komatsu excavator GPS positioning system, how to go inside to see?
In addition, you can keep abreast of vehicle conditions and remind you of timely maintenance. Through the computer, mobile phone terminal query, a prerequisite is that you must Komatsu and communication agency procurement excavator opened "KOMTRAX", is bound to your mobile phone number, the system will automatically send information to your mobile phone, convenient and quick!This is generally available for 3 years free of charge
