Q:A giant excavator (used in road construction) can apply a maximum vertical force of 2.25×105 N. If it can vertically accelerate a load of dirt at 0.200 m/s2, what is the mass of that load in kg? Ignore the mass of the excavator itself.
mass = Force/acceleration Force = 2.25e5 N acceleration = 0.200 m/s? I refuse to believe that U need this calculated as U must have these skills to be in a course in physics
Q:Method and steps of slope repair by excavator.
Due to the irregular unexcavation before the original terrain, so the excavation line will not rule, the general site surveyor will indicate the excavation line through the instrument, the law is high point there will be a corresponding concave convex, some low points will be appropriate, in order to meet the slope of the best effect. At this time, the driver's mind should be a 3D slope effect, slope repair method is similar to the first case, first dug groove. Here is a kind of groove to the foot of the slope excavation line, line connection. But in most cases we can not see the foot. Then you can only rely on experience to estimate, or locate the slope foot, total station and other tools, dig several kind of groove, then connect the sample groove, forming plane. In addition, some drivers are accustomed to using the scraper at the bottom of the bucket when the slope is repaired. Some drivers just use the bucket tooth plane. Unless it is a special soil, in general, it is better to use bucket planing. Because, because the 5 teeth are horizontal on one line, the first shovel leaves the 5 teeth print, the second shovel can be placed in the first shovel of 5 teeth print in 2, third shovel and set second shovel 2 teeth print. You can see the contrast clearly. 1 and 2CM can see that unless there is a high protrusion between the tooth print and the tooth print, then scrape it with the bottom of the bucket. All of them are regular teeth prints, and the slope will have an imaginary effect.
Q:What are the common brands of excavators?And the English logo (for example, the 31 excavator is SANY) is also written!

Q:a portion of an ancient skeleton haas been uncovered in asia. since the skull is missing, the discoveres can not determine whether the skeleton is from a human or some type of ape. the only portions that the excavators have been able to find are the pelvis and one complete leg. what should they look for?this is not true lol, just a skeletal discussion question in anatomy.
Skeletal system..the blood formation refers to the function of the bone marrow..the others are pretty self-explanatory.
Q:Ok, so the simple quot;unbolt the rod end plate, slide out the ram and replace the sealquot; isnt quite what I'm looking for.The ram is on a JCB excavator and holds probably 10 or 20 litres of fluid (which I dont want to just throw on the floor), also its 15 feet up in the air.What I hope you will be able to tell me is method, like: 1 disconnect hydraulic couplings at the piston (plug pipe to digger unit. 2 connect manual hyraulic pump to expel fluid. 3 remove clevis pins... etc. etc how to bleed (if necesary)remember this thing is big, heavy and not easy to get at.
well you pretty much either going to have to manhandle it or used something as big to get it down to the ground taking it apart is about what you think not really much to any of them but the size..... but once you get the thing off just what the order the seals come out and pretty much replace the same way sorry replacing the seals is not hard its get it where you can work on it.... man ive done a few when i was logging and they all about the same will be o rings and packing seals.... im sure you can do it but get it on the ground
Q:How come I can't find any hydraulic circuit to read and learn. I just want to read more practical hydraulic circuits to learn. I am more of a advanced technician.
See okorder /
Q:where is the backup alarm on a cat 345 excavator?
the travel alarm can be located in several places on ours they were behind the boom down by the circle gear box I have seen them behind the cab also in the right rear compartment
Q:It’s for coal mining,so the quality must must be super good.
Try this. Last time when i was sourcing a large bucket like KOMATSU PC4000,I saw they were still carrying large backhoe bucket for Hitachi excavators.Good luck~
Q:please help
Open-pit mining (as opposed to underground mining) has several advantages:- 1) Low cost of recovery - large trucks can enter the mine, get filled up with rock from a large excavator and drive away to the processing plant. 2) No need to leave stability pillars, necessary to hold up underground mine workings but which may contain valuable ore that is effectively lost to the mining company. 3) Ease of beneficiation - surface mines are usually composed of materials (oxides in the case of metalliferous mines) that are easier to handle and easier to treat in order to recover their marketable product as a result of being so close to surface. 4) Safer environment - so much less problem of rock falls, hanging wall collapse resulting in a lower injury rate than in underground mine.
Q:What's the difference between a big excavator and a small excavator?
Operation is the same, big digging faster, higher technical requirements, and slowly practice.The big dig that large excavator is the weight (weight) between 40-200 tons, bucket capacity in 0.8-1.0 between the price of approximately between 80-100W, mainly used in various large-scale open-pit mining and large-scale infrastructure construction, land reclamation and harbour dredging project.A little digging small excavator, is the weight (weight) of less than 15 tons to 4-10 tons, the bucket volume in the 0.25-0.35 between the price of approximately between 34-48W, mainly used in highway maintenance, landscaping, residential construction, municipal engineering and construction projects in the field.
