Q:Kobelco excavator computer alarm P0405 is what mean?: 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.

Q:everyone says that if you open 6 first it will excavate it before the other ones. i always open excavator 6 1st but the excavator nevers turns on or it does #11. plz help: Where the excavator breaches is largely based on luck, but it is more likely that it will breach tunnels you have opened already. I have also found that opening to the power room at round one will cause the excavator to breach at round one sometimes. Hope this helps!

Q:its a john deere 27c and i cant stand the beeping, we need to work into the night without bothering the neighbors....HELP: If you can easily get to the beeper itself, just remove one of the wires. You can plug it back in later. Or if they don't unplug, duct tape will do a great job of silencing a beeper. I've actually done that before on a forklift. You can still hear it, but I doubt that it would bother anyone.

Q:What kind of documents do you need for driving an excavator?: It is issued by the Chinese machinery department. It is common in the whole country and has the skills to be reported in our school

Q:im 35, i have blue card ,green card,first aid,confined space,working at heights,excavator and forklift tickets: Hi Dave, I am a geologist in Sydney ~ email me and I'll see what I can advise, plus pass your details to others. Cheers, John.

Q:I don't see what the difference is between the two of them.: A backhoe is usually mounted on the back of a rubber tired tractor while a trackhoe is mounted on a caterpillar-style tractor -- or is manufactured as a stand-alone track-mounted vehicle.

Q:I have 30 feet long on driveway side and 40 feet long in the back yard that needs to be dug up and hauled away ( it's probably alot of clay)? I believe it's about 65 yards at 8 feet down, 3 feet out but I'm not sure how far out you need to go. And how much will pea gravel and sand be to buy and back fill? When everything is dug out, I will need to jack up my house and jack the 2 walls back in place and then fix the drain tiles if needed, tar and fix cracks before back filled. Might have to be a mini excavator.: when I had my french drain dug out around my back wall they said something about not exposing too much of the foundation as it will not be supported by the soil that used to be against it. sounds like you have a heck of a project, just thought this might be one thing to consider before you dig out too much at once.

Q:I was so curious, what is the best substrate that you can purchase for Bearded dragons that is easy to clean and not very expensive? I know that sand is the last thing to put in the tank. But i have heard of Repti Carpet. What is that and if you know can you give me some details? Plus what is a Repti hammockgt; What is it used for? Should I get one? Please answer these and remember you guys are saving my life one anwser at a time!: This is the question that everybody asks me, Don't go with Repti-Carpet, it has tiny holes usually on the sides which means the nails will get caught and have seen toes come off because of it. i use Excavator Clay its good for desert Species and can be molded into land scape's by just adding water, just make sure it drys fully before putting bake your Bearded dragon, hope this helps!!!!!

Q:How do you drive the forehand and backhand drive of an excavator?: As we all know, the hydraulic excavator operation is accomplished through two handles, two handle before and after, left and right four directions, respectively control the excavator and the moving body part arm, bucket rod, and the rotating bucket. But according to the corresponding way, the operation mode of excavator is divided into two kinds, "left and right spin" and "front and back rotation". Then, I will talk about some differences between them.Two modes of operationThe first kind is the Japanese second-hand import machine and senior veteran driver as the representative, the left hand handle of the front, back, left and right corresponding control is the excavator's right rotation, left rotation, bucket extension and bucket recovery. We used to be referred to as "front and back spin"".The second type is the domestic new machine and the new generation of young drivers as representatives, left hand handle of the front, back, left, right, respectively, corresponding to the control of the excavator's bucket stick, bucket recovery, left rotation and right rotation. We used to be referred to as "left and right spin"".There are people who have called these two modes, "mobile phone" and "mobile phone", but due to the lack of a unified nomenclature, caused the differences on the way, before and after rotation is called mobile phone, the mobile phone is called reverse rotation, but also to rotate around the mobile phone is called, before and after the rotation is called reverse mobile phone. So to avoid confusion, said only this, before and after the rotation and rotation, to note here is "mobile phone" is refers to the rotation, and rotation or rotation before and after the "anti mobile phone", two kinds of the different mode of operation is only the left hand excavator operating handle, right invariant handle mode.

Q:What kind of excavator is trong?: 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.
