Do you understand overhead crane, gantry crane? they are the most commonly used hoisting equipment, you will find them in factory, steel mill, port and wharf.
Sometimes we are very puzzled for no motor power, now I will tell me a formula which can help you get the power very fastly, only 10 seconds, even 5 seconds.
P=Q *V *0.2 P -Power,KW Q -Capacity, Ton V -Hoisting speed, m/min.
For example, overhead crane 5 ton, hoisting speed 5m/min, and so power P= 5*5*0.2 =5kw.
Of course, you can calculte it more exactly if you are a design engineer.
Dear my friend, have you learned it?
