Q:What is the name of the excavator?
There is no specific introduction to the work of the excavator. This is a special type of work. Including the excavator is also a special operation of the documents. This document is national, regardless of area!
Q:Excavator hydraulic oil how much?
Hydraulic oil filling capacity according to different types of filling, generally 6 - 15 tons of small excavator hydraulic oil filling capacity of 120 - 200 liters; 20 - 35 tons of medium-sized excavator hydraulic oil filling capacity of 250 - 500 liters; the above said oil includes hydraulic oil system.
Q:Attentions of excavator operation
Three. Travel on soft groundExcavators in the swamp, flood and other soft ground work, should first use the bucket to try whether the ground can withstand the weight of excavators. If you forget the process, there may be serious consequences unless you are driving an amphibious excavator. Although the excavator is tracked design, contact the ground area is large, but the excavator into the mud, can not move events also occur! Just note that this can be avoided. In the swamp, flood and other soft ground work, to avoid excavators trapped, should pay attention to these: 1, first with the bucket test. 2, do not stay long in the same place. 3, go straight, turn less.Wetland excavatorIn case the excavator gets stuck in the mud, don't worry. Never try to climb out of a climbing system. That will only get you deeper and deeper. There are many ways to save. 1, if it's not deep enough, try to hollow out the two tracks. 2, if it is not, on the first try, how deep mud, if not very deep, directly to the front of the silt layer, for their own way, slowly toward the shore near the hard ground. 3, if it is infinitely deep silt, can rent a few piece of iron or board, sideways pressure to the track below, you can easily out.Four, vision blind areaThe driver's cab is on the left, the middle of the passive arm blocks the view, so there is a large blind spot on the right, especially in the rear of the right. Many excavator accidents are caused by falling or dying of the right side of the tail! So in the not very wide field work, try to let the excavator on the left, the right to set aside more space.Excavator rearview mirrorRearview mirror in the excavator is a very fragile things, often in work or transport in the touch off, many drivers will feel touched, it is not important, it is not in time to replace the new rear-view mirror. In fact, the rearview mirror is very important in excavators, especially on the right side. Accidents are often due to a lack of safety awareness!

Is the slope of the excavator climbing, what is the maximum degree of slope?,
Q:How about Komatsu excavator?

Q:Excavator drivers abroad labor groups
And we are witnesses of Hanban Chinese teachers Department CETTIC certification IPA Certified International Chinese teacher qualification exam only three institutions, two certificate commitment one-stop employment, help you houguwuyou!
Q:LOL, who controlled the new hero excavator?
And no one made it. The new hero excavator is the full name of void lurker ray Alexis, she was a group leader, who is not manufacturing.Is she in the population size of thunder Alexis, the most violent temper. She is a ruthless predator who can dig tunnels in the ground to ambush and devour her prey. Her insatiable hunger has made the peak moment to Rama Empire over the ruins. Businessmen, traders and armed caravan will bypass 100, to avoid these vast areas of people, but cunning bandits will lure unwary into thunder killing of alexis. Once detected by ray, fate is doomed. There is no hope of escape; she is death from gravel.

Nonsense, of course, the diesel.0# targetAny heavy machinery is diesel engine. Because the heat after the combustion of diesel oil and gas ratio.
