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, CNBM 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'm supposed to be critiquing an article for a class of mine.. and I don't feel like I understand the concept enough to critique his use of it... (It's an article about The Red Badge of Courage... the author talks about how the observing narrator Stephen Crane creates in the novel uses patterned reality without ambiguity... he's describing one of the scenes in which the dead soliders are somewhat personified.. describing them in terms of the living...... erm anyone take a class on realism? your help is greatly appreciated
- The okorder
- Q:What is a typical hourly wage, and what kind/how much training is required? Is there a special certificate that you have to get, sort of like a driver's or pilot's license? Does it vary much depending on what type of crane (track crane vs. tower crane)?
- i really don't know
- Q:I don't understand why or how they still exist. I know I'll get some answers saying they're part of the food chain but what animal on earth would get a sufficient meal from one of these?
- What is the point of humans for that matter... And yes I am going to give you a food chain answer. You see, crane flies start off in the water as a larva. The larva is fat and plump and fairly large compared to the adult crane fly. While in larva state the crane fly larva is a sufficient food source for many aquatic creatures such as crayfish and other nymphs such as dragonfly nymphs. While in adult form the crane fly is consumed by many birds, while it may not be a sufficient meal itself, it is one less insect that the bird consume to be satisfied.
- Q:What is the load moment of a crane?
- Cranes are classified according to their tip load of capacity. Moment of a crane depents on its type. Usually moment is calculated by the lenght of its boom multiplied the tip load it carries.
- Q:any kind of sayings
- whoops big whoop don't walk under a crane secure the crane
- Q:crane:300t lift 100t pad sizes:4.5x2 mtrs.ground bearing capacity required?
- This depends on the angle of the lift and the distance away from centre of the crane. With the lift at tipping range all 400t will be distributed along the outer half of the pad or on the extreme legs. Rule of thumb is all the load is placed under the one pad. so one pad is 9 sq metres and the load is 400 tonnes so the bearing capacity must exceeds 400/9 tonnes per square metre. 44.44444t/m^2
- Q:my father has his forklift and crane license. he needs to know how long they're vaild for
- should be good ror 3 years from the date he got it i just got mine new one last month for a sit down fork lift and crane/ trolly and its good till march 2010
- 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:Please write in days, hours, weeks, etc.I need math help!!!!
- If it takes 7*60 + 11 = 431 seconds to make 1 crane, then making one million would take 431,000,000 seconds. There are 3600s*24hr*365.25d = 31,557,600 seconds in an average year. Dividing 431 million by this gives a little over 13 years, with a remainder of 20,751,200 seconds. There are 3600*24*30 = 2,592,000 seconds in an average month. So that gives 8 months with a remainder of 15,200 seconds. There are 3600 seconds in an hour, so that gives 4 hours plus 800 seconds. The 800 seconds = 60*13 + 20 = 13 minutes, 20 seconds. This works out to 13 years, 8 months, 4 hours, 13 minutes, and 20 seconds. Though answers can vary depending on how many days you define to be in a year, and how many days in a month.
- Q:I need the answer badly
- The world would be a little less beautiful. The blue crane's role as a predator in its ecosystem would be left empty, allowing its former prey to breed without check until (hopefully) another predator moves in to pick up the slack. Otherwise the ecosystem will be out of balance.
