Specification of our tower crane:
- Q: How often should the crane be inspected regularly?
- Lifting machines are inspected regularly every two years, and explosion-proof lifting machines shall be inspected regularly every year. Must have the corresponding inspection qualification inspection.
- Q: I am doing uni coursework to design an ergonomic layout for an operator cab for a tower crane and so I need to list the required operator controls.Thanks!
- There are only two control levers that are on a tower crane.There is one on either side of the seat called joy sticks the right side joy stick controls the hoist cable to go up and down pushed forward to go down and pulled back to hoist up.The left has four functions it controls the swing of the crane and also the boom of the crane to control the swing you push the lever to the left to swing left and push the lever right to swing right.You pull the lever back to boom up and puh it forward to boom down.
- Q: type of dc motors used by electric train/subway,crane & fan.give a brief explanation to your answer?
- I believe that electric trains and subways use series motors when DC motors are used because the series motor has a torque vs. speed curve that provides high torque at low speed and low torque at high speed. Since power is equal to torque times speed, that is essentially a constant power mode of operation. I believe that mode is selected because it results in a smaller and less expensive complement of power delivery equipment and more efficient operation. Although it has been many years since DC motors were used extensively for cranes, I believe that series motors were used more than other types for the same reasons stated above. However, compound or separately excited motors may have been used for better speed and torque control at low speeds. Except for heater fans in vehicles, I don't believe DC motors have ever been used much for fans. Today, permanent magnet DC motors are used for all of the little motors in vehicles including the radiator fan that was formerly belt driven by the engine. A permanent magnet motor is like a separately excited motor or a shunt motor. The optimum DC motor for a fan would probably be a shunt motor because a fan requires increasing torque as speed increases. Today, computers are cooled by brushless DC motors.
- Q: How many meters is the tower crane installed on the edge of the deep foundation pit?
- Tower crane foundation, if set up in the foundation pit, the foundation is to pile other, general tower crane is to support the wall.Therefore, how far away from the foundation pit is determined by the distance from the retaining wall.According to the industry standard "technical specification for concrete foundation of tower crane tower crane foundation installation" (JGJ/T187-2009), the installation of tower crane foundation concrete should reach more than 80% of design strength, the tower crane foundation concrete design strength should reach 100%.
- Q: Which one is right? Are there two different kinds? This bird is confusing me.
- Whooping Crane is the name for the tallest bird in north america. A whopping crane is just a big-*** crane.
- Q: What kind of force acting in the brake system which encounter the lifting material force and to maintain its level.
- Cranes work using hydraulics and cables. The cables are wrapped around pulleys and the pulley is turned using hydraulic power. The brake system is simply stopping the pulley from turning by reducing power. The hydraulic system typically will turn a series of gears which in turn spins the pulley that the cable is wrapped around. It's different than a brake system say on a car where when you hit the brakes, pads squeeze on the interior of the wheel rim slowing it down. Cranes you just reduce power and stop the pulley from turning. They also have emergency stops. Older cranes have wedges that would be released onto the cable and then the wedges would grab the cable and slip into a ring. The narrow end of the wedges would slip into the ring first and then as the wedges increased in diameter the grip on the cable would get tighter and then stop the cable from moving. They also have systems on the pulleys to stop the pulley from spinning. They essentially work the same way as a car break. When the emergency brake is triggered, pads will squeeze on the rim of the pulley to stop it. These mechanisms work by friction. They could also have holes around the pulley and a steel pin would be pushed into one of the holes to stop it from spinning. Of course if the force of the weight exceeded the strength of the pin, it would shear.
- Q: The war stories i'm looking for are A mystery of Heroism and The Little Regiment
- i think of if a guy or woman have been to apply roman numerals i think of that they try to make the tale look exciting and eye catching by fact in case you think of approximately it there are not allot of books with roman numeral chapters, so i think of that's unique. it is not snobbish in any respect, that's distinctive and exciting than a million/one or 2/2. i think of a financial disaster with in simple terms numbers is easy yet exciting incredibly if the e book develop into approximately an murderer or undercover agent. i think of it says that the financial disaster speaks for itself no longer the quantity. i think of even naming the financial disaster could be much greater helpful by fact tit's ingenious. BQ: I p.c. on what the form is and what could greater healthful superb with my tale. as quickly as I write a narrative in a distinctive era or 3 hundred and sixty 5 days I frequently could exchange the font to make it journey. i think of that the financial disaster sort ought to journey up with the books plot. If my tale develop into ordinary i could carry on with the numbers, in spite of the undeniable fact that that's all approximately what you sense is nice and what you think of is superb on your tale. super question to invite.
- Q: I know that the whooping crane population recovered through captive breeding but how many are left currently (right now).
- There were 535 total in 2009--the population increased slightly last year but I have not seen a total for the population of 2010. Deaths can occur at any time so the number changes constantly. The Journey North site counts 281 adults in the wild western population and 106 birds in the reintroduced eastern flock. They did not give a number for the birds in captivity so I cannot give you a total. You can follow the reintroduced whooping crane population and their migration each spring and fall on the Journey North (in fall called Journey South site). They also track song birds and hummingbirds and monach butterflies.
- Q: are crane flies the most venomous insect in the world,or is this just an urban myth?
- This one is definitely a myth, one that has been applied to both crane flies and the arachnids known as daddy longlegs (more properly known as Opilionids, or harvestmen). A simple fact of their biology can put this to bed: the adults of many species of crane fly don't even have mouth parts--the adult form is used soley for reproduction, with no time for food acquisition. Essentially, they mate and die. Production of a highly toxic venom is extremely energetically costly, and when they have no ability to inject it into anything (not even for self defense), it makes no sense for a life strategy. Common sense and simple observation will also tell you that this isn't true. There are stories all the time telling of people who have died from killer bees, or snake bites, or black widows, but when's the last time you saw a news bit on a crane fly fatality? I mean, news outlets, not to mention Discovery Channel and Animal Planet, *live* on stuff like this--yet I've yet to see a special entitled Crane Flies: Nature's Perfect Assassin. ;)
- Q: I am writing a story for school about working in Dubai as a crane driver but I need to know what the purpose of a Crane driver is, how much they get payed and stuff like that. And if you could tell me how a crane driver can get admission in the first place, it would be really great. Thanx. And btw, this story is for Geography.Thank you. :)
- i am not a crane driver myself , but into this field of construction . get a licence as driver from authority just as a car driver. know how to drive the crane ad a driver know how to operate a crane as a operator. know the performance of the crane and its limits. the salary can vary depending on the type of crane and its special features. but not in the high end grade for sure unless its a very specialised crane operation. u can ask any thing more .
