Q:How does the excavator cross the ground cable?
Slowly as before to walk down the wire frame in excavator digging machine below can go over to the other side in the same ibid.
Q:Excavator voltageLow voltage alarm for several hours,
I suggest you use the multimeter to test the generator's voltage and see if there is any problem with the generator. If the above inspection does not have the unusual, must ask the specialized maintenance to help you to solve the problem.
Q:What is the function of the central swivel joint of the excavator?
The excavator chassis and the upper body do relative rotation movement, and the central joint is to ensure the supply of hydraulic circuit when turning. When the excavator turns, the hydraulic oil is sent to the walking motor through a central joint. It is difficult for an ordinary pipe to perform such a function as a central joint, and even if it is done, the pipeline life is not as good as that of the central joint
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:Import Sumitomo A5-210 excavator fault code 0087 what does that mean? Is the engine system abnormal?
Plug the road, the big pump may plug, plugging the electronic pump, and there is a large pump into the East and West, and all kinds of blocking.
Q:How much oil does a large excavator use in a day?
Komatsu 200 level 18-20 liters / hourLook what you've done. On average, 200 litres a day is enoughWhat's the bigger grade of a day for 3/400?
Q:Which is the most popular excavator on the Internet? What do you mean?
This is the Lan Xiang school enrollment advertisements, sporadic NetEase first in the region and keep abreast of Dili, after Baidu, became the popular language of network.
Q:How do you determine the bucket capacity of excavators when you know the type of excavator?
Model is 35, that is, 3.5 ton bucket capacity of about 0.11 cubic metersModel is 60, that is, 6 ton bucket capacity of about 0.3 cubic metersModel is 120, that is, 12 ton bucket capacity of about 0.5 cubic metersModel is 160, that is, 16 ton bucket capacity of about 0.65 cubic metersModel is 200, that is, 20 tons, bucket capacity of about 0.8 cubic metersModel is 220, that is, 22 ton bucket capacity of about 1.1 cubic metersModel is 240, that is, 24 ton bucket capacity of about 1.2 cubic metersModel is 270, that is, 27 ton bucket capacity of about 1.5 cubic metersModel is 300, that is, 30 ton bucket capacity of about 1.6 cubic metersModel is 400, that is, 40 ton bucket capacity of about 1.9 cubic metersModel is 250, that is, 45 ton bucket capacity of about 2.1 cubic metersThe above generally refers to the natural excavation pileDifferent brand excavator models are differentPC200-8, PC stands for the Komatsu excavator series, 200 represents the 20 ton class, and the -8 represents the new generation of algebra.Carter 306, 3 represents the Carter excavator series, 06 represents the 6 ton class, and the new algebra is represented by ABCD
Q:Which expert knows the excavator of this brand of Singway?
Shanghai dragon road foreign trade company purchased the domestic excavator factory, OEM production,Shanghai dragon road translates into English, is Sinoway
Q:220 how much earthwork can an excavator dig in an hour?
If you work ten hours a day, you can do eight hundred or nine hundred parties a day. An hour, that is, dig eighty or ninety parties
