Q: Please write in days, hours, weeks, etc.I need math help!!!!
it takes 431000000 seconds
Q: don't its wheel provide the same amount of friction?
the capacity of a travelling crane relates to its resistance to tipping, and is dependent upon wheelbase, which can be extended by use of the outriggers, and counterweight (the big boxy thing at the back of the crane). Every lift requires a firm and stable platform which is what the outriggers provide. For every lift (weight) and reach (how far from the slew point), there is a limiting capacity factor. This is required to be posted within the operator's cab. The actual load lifted may be monitored by a load cell on a running rope (or other location), and through a computer control, limit the actual capacity of the crane.
Q: Equipment safety of tower crane
Some use units over profit, not pay attention to safety, small horse cart, overloading seriously, tower crane accident is one of the main source of high incidence. Some manufacturers in order to meet the construction requirements of the enterprise, expand sales, to occupy the market, will be independent of height increase, the boom will be lengthened to increase the tower coverage, this is bound to reduce the stability of tower crane, reduce the rated lifting weight, increased insecurity. There are some private and unauthorized modification of the tower crane tower crane in the assembly, this part of the tower crane for a long time in the second-hand purchase price is cheap, not willing to invest in maintenance, and frequent failure, which should arouse our attention, we should seek truth from facts, according to local conditions, to solicit the views of all parties on the basis of the introduction of relevant the supporting policies to solve this problem. By strengthening the safety management of several aspects of tower crane, it can effectively prevent all kinds of accidents in the process of tower crane use, and play a preventive role. Practice shows that as long as the construction enterprises, factories, construction administrative departments, in accordance with the tower crane detection institutions can each link to do, to strengthen the safety management of the tower crane, can effectively control the incidence of major accident of crane.
Q: I am making a lot of little paper cranes, and so far I have 144 cranes. I want to know what different number of cranes mean. Like, what do 100 cranes mean? Good luck? Long life? I don't know!!! So what do 100 cranes and 1000 cranes mean?!? Please answer if you know, this question is almost driving me crazy!!!!
A Japanese legend indicates that anyone who folds 1000 paper cranes will be granted a wish. Sadako Sasaki was a Japanese girl who died from radiation sickness from the A-bomb dropped on Hiroshima. She wanted to fold 1000 cranes before her death at the age of 12. There is a peace monument to her memory in Hiroshima, and people from all over the world send paper cranes to the site.
Q: It`s like a big box filled with toys and u insert a coin and then u have 2 handle the small crane to pick up a toy...
Skill Crane. We used to have one in our arcade.
Q: is this normal? I mean VERY VERY afraid. I mean i won't scream but if i see a someone (except other guys) i will hug them tightly and beg for them to kill them... and how can i change this?
Pshh I don't blame you!! Crane flies are ******* hugeee dude!! The fact that there legs are so long and they just come flying at you, omg you just want to diee. But I'm not scared of spiders, unless they are huge like tarantulass!
Q: Like those three hundred or four hundred meter tall skyscrapers, where are the bottom of these tower cranes installed?It doesn't go up from the ground, little by littleWill the crane not fall down?
The installation of tower cranes is certainly a guaranteeThe installer is dangerous,
Q: I ve read about crane flies and many experts say they do not bite nor sting. Ifor that is the case, what is the little piece of their abdomen that looks like a stinger?
It's an ovipositor. The thing goes under bark and lays their eggs there.
Q: Where are levers used in and throughout the crane
the boom itself can become a lever if the load lifted is greater than the cranes capacity and causes the crane to tip over--the weight acts upon the boom(lever)--the pivot point of the boom becomes the fulcrum and OSHA will soon drop by to find out why!
Q: How to distinguish self lifting tower crane with counterweight and lifting tower crane without counterweight
2 the tower crane without counterweight is mainly the city fast loading tower crane. It is characterized by the absence of balance arm, and it is impossible to have counterweightThe layman can not tell the can see the appearance, there are long steel structure before and after the weight of the tower body, and no weight of the tower body with only one steel structure (i.e. jib crane, structure)
