Counter-balance weight calcualtion
As opposed to conducting a practical experiment, can anyone help me with calculating the counterbalance weight required to make a frame lift evenly?
I have a frame, 18metres long x 2metres wide weighing 5 tonnes - when it is lifted using a 4 point lifting beam on designated lifting points, it lifts approxiamately 15 degrees out of balance. Is there a calculation for determining the counterweight that needs to be added at one end to rebalance the load?
