To calculate the work done by the two tandem heavy lift cranes, we can use the equation:
Work = Force x Distance
First, we need to calculate the total force exerted by the cranes to lift the concrete beam. The force can be calculated using the weight of the beam:
Force = mass x gravity
Given:
Mass of concrete beam = 120 MT
Gravity = 9.8 m/s^2
Force = 120 MT x 9.8 m/s^2 = 1176 kN
Now, we can calculate the total work done by the cranes:
Work = Force x Distance
Given:
Distance = 7.5 meters
Work = 1176 kN x 7.5 meters = 8820 kNm (kilo Newton meters)
A 120-MT concrete beam is lifted from the floor by two tandem heavy lift cranes up to a target height of 7.5 meters.
