Q:How to depressurize a caterpillar excavator?
Did you mean to post this in Travel / NSW? Perhaps you can try one of these categories: Home Garden > Maintenance Repairs Cars Transportation > Maintenance Repairs
Q:I want to buy a good and original excavator, who can tell me where can buy and which brand is good?
There are websites all over the internet selling heavy equipment. I think I have seen excavators on OKorder. Why not rent locally? Does this help any? John Deere and Caterpillar are real good.
Q:What kind of excavator is DEERE?
John Deal excavator,The main brand sales in North America, Hitachi OEM for excavator.In addition, the company had a joint venture with Xu Wa to produce excavators, the company name She John Deal
Q:What can i do to keep the neighbors dogs from digging under the fence! They don't care!?
Unfortunately you may end up bringing a police report or trying to speak with your neighbors again about the dogs digging in, maybe suggest the shock collar.... you can spray apple bitter all day long, use those toe pads, place rocks under the fence line, and they may find a way to dig in, even when the shock collar battery dies. I own a beagal and he'll dig to china if you let him... 3 times and back. We ended up using a shock collar fence line burried under the fence line to keep him from digging under the fences.
Q:hydraulic problem on Cat 325b excavator?
Hydraulic problems are tough to figure out sometimes, but I believe you're right. It sounds like you have internal leaking in the cylinder. Because it shows up under load. Right now it looks like your only option is to tear down the bucket cylinder. If the piston looks good then you could probably get away with repacking it. But if you see scoring on the piston, then have it repaired before repacking. If not than the same problem will show up again real soon. Hope this helps.
Q:weight of american 35 excavator?
Need to know more info. From your question possibly 35000 lbs.
Q:How long is the normal wait to get an excavator to start digging for a basement?
It depends entirely on the area of the country you are in, the weather, and the excavator you have chosen. There is no average wait time. If you are building your own home, you are at a disadvantage with an excavator, and will be at a disadvantage with every subcontractor you deal with during the construction of your home. You are only building one home, while the builders they normally work for build multiple homes per year. Every subcontractor will put off your job and give priority to the builders who hire them month after month and year after year. Unfortunately, you may be a one shot deal. Good luck with your situation.
Q:So when is my new dump truck and excavator going to fall out of the sky and into my lap so I can do gov work?
LOL - Are you saying that gov. workers are dead? After a dump truck and excavator falls out of the sky and into your lap = I strongly believe you would be dead.
Q:easy stump removeal?
Dig it out with an excavator or grind it down with a stump grinder. You can rent either from a local tool/ equipment rental center
