Product Description:

Excavator big and small booms include standard boom and lengthening boom, wherein the lengthening boom can be classified into two-piece lengthening boom, three-piece lengthening boom, slipping telescopic lengthening boom and barreled telescopic lengthening boom. Moreover, we can design and produce all kinds of standard booms and lengthening booms for other brands of excavators, and have ability to ensure structural strength, use performance and quality of product by stress analysis, selection of materials, technology and process, design and making by virtue of advanced computer-aided design system, diversified processing equipment, well-trained staff and actual application and experiences. An internal buffer board inside the boom can bear tension loading and further the service life of excavator.

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:Excavator theory
The excavator is driven by the engine work in pump operation, the pump is divided into pump and pump, and then by the operation of the hydraulic excavator driver rod of the hydraulic oil distribution to the pilot valve and main control valve, such as the hydraulic oil distribution to the main control valve, hydraulic oil delivered by the main control valve to the arm; small arms; dig bucket cylinder, and then drive the arm; small arms; digging bucket. If the hydraulic oil is allocated to the pilot valve, the hydraulic oil drives the motor through the pilot valve to make the excavator rotate and drive.
Q:Which country is Carter excavator?
In fact, Carter is also produced in Japan on the nameplate, there are MADE, IN, JAPAN
Q:Is the power supply voltage of the excavator AC or DC?
The motor and control system of the excavator is supplied.
Q:Ask you, great God, excavator, fight wild, is the main Q, vice W, or the main Q, vice e!!!?!???
The main w Kiyono fast, the main Q for arrestChasing the answerAlthough not played, but I think it should be the main W, deputy Q, e point
Q:How much are the first pilot pressure and the two pilot pressure of the excavator?!
The two pilot pressure is usually 10% of the pilot pressure, and the two pilot pressure is controlled by the handle button. A pilot pressure is required with the normal operation of the system is generally about 35kg, two pilot pressure used in special conditions, such as the bucket bucket must use to dig out from the stone soil and the mining stress exceeds the system overflow pressure 345KG system set in a mining buried in the earth stone, then open the two pilot system, the sum of the overflow pressure at that time as one and two times the pilot pressure is 380kg, the working pressure increased to complete this action.
Q:Is the excavator a motor vehicle?
Excavators are special motor vehiclesIt is not allowed to carry passengersAnd you need a special driver's license to drive the excavator
Q:Explanation of tail slewing and tailless rotation of excavators
Ultra low noise designThe engine adopts semi floating cylinder head cover and coating molybdenum disulfide piston, and adopts low noise F fan, with sound proof effect of sound absorption material and other sound insulation measures, realized low noise.ROPS/FOPS cabThe world standard ROPS/FOPS cab (with seat belts) is adopted. Improved operator safety.Auto idle = fuel efficientThe joystick stops for 4 seconds, the engine is automatically converted to idle operation, the joystick is operated again, and the engine immediately reverts to its original speed.Liquid crystal display with self checking functionData, hours, fuel, water temperature, engine speed, registration information of "SS keys", etc. can be clearly displayed during normal operation. Once there is an exception, it will show up immediately, allowing you to keep the equipment running at any time and place.The automatic display of fault detection information can be conveniently reported from the scene to the maintenance personnel, and the automatic save function of the fault history record can be automatically saved, and the inspection time can be saved.Simple operationSpecial operations are not necessary.Just insert the key and turn it as usual.Single key system.Start, door lock, hood, tank cover and other common keys.Security anti-theftThe engine cannot be started with a non registered key of the same shape. If the attempt is started with a non registered key, the security system starts working immediately and gives an alarm.(even if the key is removed, continue to call the police; start with the correct key and stop the alarm)
Q:What are the differences between a hydraulic excavator and a backhoe?
According to the different work methods used excavator backhoe excavator item. Hydraulic excavator is a very abstract concept, it can be divided into positive shovel, backhoe, dragline and so on. You can say is that if the hydraulic excavator shovel, including backhoe, dragline and other types of construction, and only one, and generally use the backhoe excavator backhoe excavator, so apply the item
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.
