- Q: Drag Line Excavator - Are there any Digging Functions where this kind of Excavator can't be used?
- Any kind of precision trenching or digging where accuracy is required, such as foundations, etc requires a backhoe or other controlled digging device. A drag line is better for open pit mining or other kinds of excavation where accuracy is not as important.
- Q: What is it? Did it shock the ground with hydraulic pressure?
- The principle of hydraulic hammer is to select the most suitable hydraulic crushing hammer according to the type of excavator and the environment of operation.According to the mode of operation classification: hydraulic hammer broken into hand-held and airborne two categories; according to the principle of classification: hydraulic crusher is divided into full hydraulic type, liquid gas combination and nitrogen explosion type three categories. Liquid gas combined by hydraulic oil and rear compressed nitrogen expands and pushes the piston to work, the vast majority of breaker belongs to this kind of products; according to the classification of valve structure: hydraulic breaker divided into internal and external valve type valve two.
- Q: Ok, I'm going to repost this question, because it's NOT Bob the Builder! Since when was Bob the Builder in the early 90s??? lolHere's my question: Ok, this is driving me crazy. I can't think of a show I used to watch as a kid. I'm pretty sure it was on PBS kids (that's really all I used to watch), but I looked at a list of old programs and I can't find it! It was a show where there was this man (possibly a construction worker) and he was friends with a living excavator-like machine. I can't remember exactly if the machine talked, but it was definitely quot;alivequot;. She had a name too, I think it started with an quot;Mquot;? I just can't think of it! I used to watch this show in the early 90s. Any ideas of what this show is?Thank you!

- Q: I'm puzzled and there must be a logical explanation. Why for year's did they say that the 2 missing Romanov children were likely to be Anastasia and Alexei, and people were convinced she may of survived. (I'm not convinced now however). And now that 2 more bodies have been discovered the media are saying MARIA and Alexei's remains have been found. Does that mean then, that Anastasia's body was discovered back in 1991 with 4 other members of her family, when we assumed it was Maria? Or are they still unsure whether it's Anastasia or Maria that has just been found? Sorry but you may agree it's all a bit confusing and I just wondered whether anyone out there can clarify the situation with Anastasia and Maria. Thanks.
- Guess what? Rachelle can copy paste! All the Ramonov girls were close in age. I recall reading that there was always some confusion over which girl was missing even though popular culture honed in on Anastasia. I believe the confusion came because of their size (anastasia being younger yet bigger than maria (?)). Anastasia also had imposters like Ana Anderson who many people believed to be the escaped Grand Duchess but now we know they were all frauds. Once the last 2 bodies were found though it became clear who was who and yes Anastasia was found in 1991.

- Q: i put in a fake rock background and side walls too by the way its really nice so anyways the substrate is excavator its really neat. it is a sand substrate but when you mix it with water it hardens to a concrete like sand really low risk of impaction and just in case she does get impacted i give her warm baths with a massage 1 day a week and no signs of impaction so every time i take her out to hold her she poops when i give her baths not even when she hits the water yet she pooped but never in her enclosure please help but every day i do make sure she poops but i would really like her to poop without me having to take her out to poop before this setup she was on repti carpet and pooped without any problems please help and give ideas thanks
- Maybe the best thing to do is test some new foods and substrates out. Every week you just change the substrate type and food type here are some good simple substrates you should try newspaper, artificial grass and reptile carpet. And with the food try feeding her a differant type of food every week, basically it's just about trying to find the right combination for your reptile.
