how many power required to drive 45 Meteric tonne load with its calculation?

Question

above quesion for eot crane

Answer 1

You have not furnished sufficient data to compute an answer. I don't know what an EOT crane is, but you need to know the rate of ascent. (ex. meters per second)

In the mean time, here is some material to assist you with the necessary calculations.

Power = work / time = (force * distance) / time
Work = force * distance
Force = mass * g

Power = (mass * g) * distance / time

Power = (45,000 kg * 9.8 m/sec^2) * distance / time

Power units are N-m/sec, which are also equal to watts (W)

Convert to horsepower using the conversion factor of 1 HP = 746 watts.

Good Luck.
