Q: Stolen : Chain Saw, axles for a trailor... help jjj
Find a concrete and solid evidence to nail the culprit (ie. photo or hidden video camera, credible witnesses, etc.). Send all the collected evidence to the concerned authorities in the company for appropriate action. As much as possible, be anonymous and avoid exposing yourself in danger.
Q: It's about 10 x 15 feet and also includes a wooden deck.
I run a penal complex in VA and we had an same problem with a clean outdoors freezer that change into laid in part in the floor on a concrete base. It rose 14 inches till contractors got here across out we laid it on precise on an undrground move. i desire that is not your case; we had to desert the unit at it is modern-day placement and ended up growing to be a drainge pond there. there is a few thing causing the pool to enhance upwards, concrete doesn't flow in that way except it is helped. seem into that theory for a lengthy time period. Godspped and sturdy success.
Q: How to learn excavator
Eager to ask friends, 2011-10-10 ha ha! Well, that's a good question. If you want to know the answers that are in place, the answer is not mine. Here you are.. Don't ask who I am, nor ask me what I do. I'm just a legend!! Want to learn excavators, you must first determine whether you want to enter the industry, yes, in recent years, the industry is very popular, wages are very generous. Importantly, there will be a lot of money in return. Simply speaking, must be afraid of hardship, because most of the work conditions are relatively barren hills, wild mountains and the like, sparsely populated. Be tolerant of loneliness. The beginning of learning excavators, the most important thing is to listen to the master's words, to please the master. Keep in touch with people, and these don't need to be understood. The master at work when you have to pay more attention to the observation of many master movements, the penetration angle of the bucket, with the combined action of arm two arms. In fact, the operation and so on are not very difficult, about a week can master.
Q: a. true b. false
a. true more capital to labor means replacing hand shovels with excavators.
Q: The tracks are kinda loose and I want to adjust them.
you hve a plate in the front on the outside, remove the plate and you will see a grease fitting, pump grease into the fitting until you reach desired tension. aint sure what the measurment is on it but dont get to tight or youll do more harm than good. track should droop a couple inchs i would think. good luck
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: Bobcat= small front end loader not animal
You could build a pond with a bobcat, you wouldn't be able to just dig down though, bobcats don't have enough breakout force to do it efficiently. If your pond site is mostly created by building an earthen dam, then you could certainly do that. The bigger problem would be packing the clay layer with the bobcat, it just doesn't really weigh enough or have the proper drive system, you could always pin up some pigs in the pond to pack the clay, that's how the old farmers used to do it here in Missouri.
Q: How long does the excavator take on the moon?
depending on how many people you have the time may very from 30mines-2hours
Q: is there a graph or chart showing the maximum gradiant a 360 tracked excavator can dig at?
Manufacturers usually have that information. Try their web site,
Q: 31, 75 excavators
Do not know where you are a friend, you can consult the local agents, prices are somewhat different, but not large, 9 models should be around 440 thousand. According to industry reports, 31 machines last year sales of 20614 units, the first national sales, especially small excavator, China each sold 4 units, one for 31.
