FAQ of TC7021 Tower Crane
Q: What is the principal to quote the right tower crane to the client?
A: First, we need to know clients’ requirements. Normally the following information should be clarified by the client: max lifting capacity, height (height under hook), tip load and jib length.
Second, we need to know what the foundation requirement from the client is. (Fixed/undercarriage/ undercarriage with traveling system), mast section type (panel/integrated), power supply source (voltage, ampere and frequency), the distance between the machine and power supply……
Third if there are special needs, we could suggest proposal according to clear data provided by the clients. End-user, as construction machinery buyer, knows the site situation well and should make decision, such as the machinery specification, type…….
Q: What about our tower crane's warranty?
A: Usually there is one-year quality warranty including main electronic parts (not including consumable parts). There are consumable spare parts together with whole machine and normally they are enough for one year.
Q: What is 3 main mechanism of the tower crane?
A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.
Q: Can you equip with light on tower crane jib, monitor, remote control and anemometer?
A: Sure. All of these could be provided with extra cost upon the clients’ requirements. But according to general practice, remote control is not suggested because most of the operator feedback operation in the cabin will provide a wide working view.
To Lead The Revoluation of International Trade
- Q:I am looking for guidance on determining the optimal design parameters for the design of an overhead travelling crane when considering a span of 60m and a lift requirement of 2500Tonnes. If not possible what would be the maximum lift for the same span
- Is this for a nuclear power station? If 2500 Te and 60m really are the specified loads and span then it is likely that it will be used very seldom. In theory you can design for any load to be lifted but maintenance on a crane system that is used once a year (10 years?) is a real problem. The main items to consider are: Availability of winches and bogies which then dictates running beam and rail sizes. For the spanning beam several alternative sizes needed to be designed and then costed. It will be not just weight but transport costs that determine the most efficient sizes The overall height of the crane will then determine the required roof height assuming that the crane is under cover. For comparison the Harland and Wolf cranes in Belfast called Samson and Goliath can lift 840 Tonnes each. Overall design needs to consider speed of travel, acceleration and deceleration rates and a host of other things.
- Q:I can't find anything about this online, and I've never heard of it before.... I'm looking nearby for a Karate club to join, and came across this.I've heard of white crane kung fu, but not karate...
- Probably an Okinawan style of Karate with strong ties to Chinese White Crane Kung Fu.
- Q:How do they get the tower cranes (the ones used to build sky scrapers) so high? It's not like they can ship them all in one piece so how do they make them taller? I've always wondered that...
- Seems have a big turn in a person's life. The external form of a person is ideal in the eyes of the planet when every feature is assembled in flawlessness or very nearly there. Of all of them, height represents an important role. Height is not just lots is one of the critical standards in plenty of areas: sports, being a part of the security force, wooing someone, obtaining a work or just bolstering one's assurance therefore
- Q:Please help. I need real answers.
- About Ichabod Crane, the school master, Washington Irving writes in A Legend of Sleepy Hollow: He was, in fact an odd mixture of small shrewdness and simple credultiy. His appetite for the marvellous, and his powers of digesting it, were equally extraordinary; and both had been increased by his residence in this spellbound region. Ichabod Crane digests Cotton Mather's (a Puritan preacher) History of New England Witchcraft, a book in which he firmly and most potently believes. He spends many hours reading Mather's work, and fluttered by his excited imagination he believes that he is struck with a witch's token at times. To drive away the evil spirits, he sings psalm tunes. Nevertheless, Crane still delights in the supernatural, so he spends winter evening with the old Dutch wives who exchange tales of ghosts and goblins around the fire. In turn, Ichabod entertains them with Mathers's reports on witchcraft, as well as predicting what the sounds in the winter air portend.
- Q:why the new york cranes collapsed?
- Update, Tuesday, 1:17 pm: Investigators have narrowed down the cause of the NYC crane collapse to a $50 strap of nylon fabric that snapped under the weight of a six-ton piece of steel. More details here.
- Q:Does tower crane belong to special equipment?
- Tower crane is a high-altitude operation, the type of work belongs to special types of work, equipment belongs to special equipment.
- Q:I saw this documentary on ancient buildings like the pyramids and it said that we don't have a construction crane that can life the stones used to build some of these ancient structures.So I gotta wonder how much the strongest crane CAN lift....or is that just fantastical nonsense about cranes not being able to lift those blocks?
- Those stones are small compared to what cranes can lift. I did find this Liebherr the heavy equipment company have developed a new all terrain nine axle mobile crane that is the worlds most powerful. The Liebherr LTM 11200-9.1 has a maximum lifting capacity of 1,200 tons with its powerful 100 metre (328 ft) telescopic boom. another: Deira City Centre was the crane’s first lift as it assisted in completing the work in less than 30 hours in what would have otherwise taken an approximate 20 days. The monster machine can lift up to 1,200 tonnes and cover an area over 100m wide. The operational weight is 96 tonnes and the total counterweight is 202 tonnes. Average weight of the stones in the Great pyramid is 2.5 tonnes. So either of those cranes could lift over 400 of these at once.
- Q:Where are gears used on a crane?
- Don't okorder
- Q:A. Power LinesB. WaterC. FiresD. Overturns
- Dangerous to whom and exactly what does overturns mean? Operators are most likely to be killed when a tower crane breaks (is this an overturn?) because the operator is several hundred feet up in the air in the cab. Hitting power lines can be risky to the operator if dumb but staying in the cab is likely to be safe (stepping out may kill in touching ground) Overturning a ground based crane is going to hurt someone in the area much of the time.
- Q:I am currently in the Air Force reserves as a heavy equipment operator. I really want to learn how to become a tower crane operator. How would I go about doing this? I live in CA.
- Hey Patrick, I was formerly a tower crane erector out of Washington DC. BUt, to yor question, I wold highly recommend you go to your town's Operator engineers Union Hall and inquire as to the qualifications and requirements to enroll in their apprenticeship program. Yes you will have to go thru the apprenticeship program. A tower crane operator is a coveted job among operators... You have to learn to hold your 'P for long periods as well as have great depth perception You coming out of the service, you should be given some preference Good luck
