Q:Tower crane driver simulation exam which website?
The driver of the tower exam is nothing more than the operation and safety of knowledge.
Q:When is the crane fly season over? I am really really scared of them?
It's like they have no control over their limbs, and flutter onto you. We had one in our living room called Henry who my mum tried to kill because we are all so scared of them, and she disabeled it. It had a squashed leg. I felt sorry for it. It's proably because of global warming that they are still here.
Q:Is a tower crane a fixed type crane? Still can walk? Thank you
The tower crane is the equipment that can be used in the construction site and is not to walk.
Q:In the poem "The Wayfarer”, what is Crane's ironic comment on the pursuit of truth?
On a semi-close inspection, it would seem to me that Crane is saying that, ironically, the truth hurts. He's making a statement similar to Shakespeare in Hamlet. Hamlet is NOT muddled by indecision, as so many poor readers have often thought, but he sees much too much of the truth of the way of the world, and sees how futile and terrifying it is, and is embarrassed, or even humorously angered, that he should be asked to fix the world in the face of such impossible distress and futility. Similarly, the path to truth in Crane's The Wayfarer is overgrown with painful daggers which, if you step onto the path, will cut up your feet; if you take the path and find truth, you'll be hurt and dumbstruck and terrified by this path, so that the Truth (with a capital 'T') itself convinces the poem's 'hero' to turn to a different path, to choose something other than truth. And he doesn't even need to walk the path at all, only get a bit of a glimpse into truth, in order to be terrified by it.
Q:Give me 5 facts about Stephen Crane?
Susie, I am sorry I missed the original question so I don't know what the norm may be. I tend to side with CC. Why compare one country or person to another? Why is being 5 years behind (if that is the case) the rest of Europe bad? One of the heirs to Sam Walton's fortune (huge, monolithic discount store in the USA, Wal Mart) drives a Ford F 150 pickup truck (a run of the mill, average, regular vehicle) certainly not commiserate with the funds she has available to spend. She choses to be 'behind the times' so to speak. Who ever said that all technology is beneficial? Whoever said that having electronic relationships via the internet is better than greeting, smiling and talking with your neighbor? Personally, I would rather be a little anachronistic than futuristic. But that's me. And I have great respect for you and your country. Is it 5 or 10 years behind anybody? I don't know. Is it better or worse than anybody? I don't know. Is it different from anybody? Absolutely, and I am glad for it.
Q:how can i calculate size of battery and how can i design ups system to operate eot cranes which have 100 kw to?
To account for the inefficiencies, and startup currents, you should have a 200 kW (200 kVA) inverter with peak power of 800 kW. The batteries would have to store and deliver about 150 kW. But lead acid batteries would need to be of a higher capacity to guarantee that power level for 1/2 hour, which calculates to 75 kW-hour. I'd say 100 kW-hour capacity. A large 12 volt battery can store about 100 amp-hours which translates to 1 kW-hour, so you would need 100 of this size batteries connected in series/parallel. I made a lot of guesses, you should get better numbers for the motors, the inverters and batteries for a more accurate calculation. An inverter of the size needed will not be a 12 volt unit, but probably 48 or 96 volts DC. so you need to configure your batteries in series parallel to get that voltage. Altogether, the 100 large batteries make this not a practical solution. There are lots of large cranes in the world, what do they use for backup? And why do you need backup. With no power, the clutches would keep the crane and loads fixed in position, my guess.
Q:Hogan Hero Bob Crane was found murdered right? Did they ever solve the case as to who did it,or was it another?
Crane had just spurned his long-time friend John Carpenter. Carpenter was tried for the murder based on blood found in a car he rented, however he was acquitted as a murder weapon could not be found. The case remains officially unsolved.
Q:can some one give me contact details for O & K Marine Crane Manufacturer?

Q:The arm of a crane at a construction site is 12.1 m long, and it makes an angle of 30° with the horizontal.?
(a) What is the magnitude of the maximum torque the crane can withstand if the maximum load the crane can handle is 500 N? τ = FL τ = 500(12.1cos30) τ = 5239.45 τ = 5240 Ν•m (b) What is the maximum load for this crane at an angle of 35° with the horizontal? τ = FL F = τ / L F = 5239.45 / 12.1cos35 F = 528.6109... F = 529 N I hope this helped. Please remember to vote a Best Answer from among your results. It's good karma as it keeps things in balanced exchange.
