Q:How do you become a crane operator?
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

Q:How many of you will bow down to me, I am Denny Crane after all?
I loved Denny Crane!!!!!!
Q:What are Cranes and Derricks used for?
Cranes are used for lifting heavy equipment. Derricks are used to drill for oil. They are two different things.
Q:How do they erect the construction cranes?
How do they erect the construction cranes? Not very well according to the news of them toppling down of late. Seriously, the cranes are lifted upward one or two floors at a time as the building progresses upward - this is usually accomplished by pulling them up into place with heavy cables and powered winches.
Q:Equipment safety of tower crane
The boom of a tower crane is divided into two types: horizontal and compressed arms. When the movable arm is horizontal, the carrier car runs along the horizontal arm with variable amplitude and amplitude, and the movable arm is longer, but the boom has a larger deadweight. The arm for the strut type when the tractor boom luffing mechanism pitch amplitude, amplitude motion than horizontal smooth, but its relatively small weight.The weight of a tower crane varies with its amplitude. The product of the weight and the amplitude is called the load torque, which is the main technical parameter of the crane. Through the rotary mechanism and slewing tower crane, lifting height, rotation and walking the inertial mass, so it needs to have good control performance, especially the lifting mechanism can fast, slow, heavy and light load installation fretting. In addition to the general use of resistance speed regulation, but also often use eddy current brake, FM, pole change, SCR and mechanical and electrical joint speed regulation. When the crane in the layout to drawing, especially in real estate development area, residential buildings, such as tower crane, but also to consider the safety distance of adjacent tower crane, two in horizontal and vertical direction to ensure the safe distance of not less than 2m, the adjacent tower crane tower crane and interference can not occur. Try to ensure that the tower crane in the wind is too large to be free of rotation. The safe distance between the rear arm of tower crane and adjacent buildings shall be no less than 50cm. The safe distance between tower crane and power line meets the requirement.
Q:A crane lifts a 425 kg steel beam vertically a distance of 117m?
Force=mass x (acceleration) -Gravity must be taken into account F=425 x (1.8 -(-9.8)) F=4930 w= F x deltay w= 4930 x 117 w=576810J
Q:What happens to the sky crane after it drops off the Curiosity rover?
Well, ..., it flies away and crashes in the distance. In the coming days the MRO will fly over the landing site and send pictures back of both the parachute, Heat Sheild, Capsule, and Sky Crane. In the meantime watch the video below. It will help you learn more information about what happened. --- Edit --- Check out the last link below. it show the parachute, Capsule, and the heat shield (after separation) all still in free flight. Give it some time they'll find the sky crane for you. --- Edit 2 --- Here's the link to a photo showing where the Heat Sheild, Backshell and Parachute, Curiosity, and yes, the skycrane are in relation to each other on Mars. See: www.nasa.gov/mission_pages/msl/mu...
Q:Are steam cranes still used to clear train derailments?
No, they don't. They have to use road cranes - think of the accident at Grayrigg some while back. They had terrible trouble clearing the line as heavy lifting equipment had to be brought quite a distance over muddy fields. I seem to remember special temporary roads had to be laid. Similarly with the freight accident in Scotland a few weeks back, roads were closed, again whilst wreckage was cleared.
