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:What is the structure of the excavator?
Thoroughly inspect the surroundings and bottom of the locomotive in accordance with the following sequence: 1, whether there is oil, fuel and coolant leakage. 2, whether there are loose bolts and nuts?. 3 、 is there any broken wire, short circuit and loose joint of the battery in the electrical circuit?. 4, whether there is oil pollution?. 5, if there are rumors accumulation. Daily maintenance notice of daily inspection work is to ensure that the hydraulic excavator can be an important part in maintaining long-term efficient operation, especially for the self-employed, do the usual daily inspection work can reduce maintenance costs. First of all, around two laps to check the appearance of mechanical and mechanical chassis or unusual, and whether there is a rotary bearing oil flows out, and then check the braking device and bolt fastener track, tighten the screw, the change of the change in time, if you need to check the tire wheel excavator is whether there is abnormal, and pressure stability. Excavator bucket teeth to see whether there is greater wear, it is understood that the bucket teeth will greatly increase the wear and tear in the construction process of resistance, will seriously affect the work efficiency and increase the wear and tear of equipment parts. See if there is crack or oil leakage in the bucket and the cylinder. Check battery electrolyte to avoid below level line. The air filter is an important part of preventing dust from entering the excavator. It should be checked and cleaned frequently. Always check the fuel, lubricating oil, hydraulic oil, coolant, etc. whether to add or not, and choose the oil according to the requirements of the manual, and keep it clean. After starting check 1, whistle and all instruments are in good condition. 2, engine starting state, noise and exhaust color. 3 、 is there any leakage of oil, fuel and coolant?.
Q:What machine/or tool can my boss rent to remove desert shrubs quickly and efficiently?
a 4x4 truck with a winch or a long chain
Q:Which brand is good for excavator?
The man upstairs is detailed enough. Buy a brand car, those who have never heard of it, then buy parts are not good to buy,
Q:Dozer\excavator work. How much $$ to dig a hole?
You would need to hire two machines to have4 flat verticle sides. A front end loader and a back hoe. I would take only one day and both usually are hired for $125 per hour with an 8 hour minimum. So your looking at $2,000. If you dont mind one side having a ramp to the front end loader can go in and out. Then you'll only need the one machine. $1,000. This time of year, find a pool builder. He's probably and slow, needs the work, and willing to negotiate.
Q:How about automatic flameout of excavator?
Two, new equipment or condition has been good, is too much moisture in diesel, or diesel filter plug, or air filter plug, leading to inadequate combustion in the engine, the symptoms are black smoke, suppress the car flameout.The solution is..:1. check that the oil circuit has been damaged, leaked or blocked.2. water the diesel tank and oil-water separator every morning before the train starts.3. often do maintenance, often change the filter, the engine is worth more than the filter.4. and the formal way to diesel, fuel in the fuel tank cover stockings filter.5. clean the tank every other period of time (3~6 months)
Q:how much can a used komatsu excavator pc200-5 clocking about 4000-6000hrs cost?
even tho it has that many hours on it plan on dishing out 50 grand or better. Personally Id go for a John Deere. I used to be a heavy equipment mechanic so i think my opinion is valid.
Q:what uses hydraulics or pneumatics???
hydraulics excavator, forklift, bobcat, bulldozer, crane__pneumatics elevator, pneumatic car shocks,pneumatic pistons,robots,air power tools.
Q:Are there any benefits to owning construction equipment other then for personal use?
The benefit is that you can write off a lot of expenses. You are still out the money. But, save a lot on taxes. The best benefit is that you are friends with the boss. HA!
Q:Modern 305-7 excavator oil consumption per hour, how many liters oil full load?
Diesel engine can be estimated by specific fuel consumption, but to know the normal work of the power consumption, if this is full load work, you can press the nameplate power, generally 180 grams / horsepower * hours, about 0.2 liters / horsepower * hours.
