Load cells in cranes.
When for any reason the cargo runner (the wire lifting the hook) in a crane, is not pulling in the actual vertical direction (as in the case commonly found when working in 2-cranes lift modality) do the load cell sense the higher component involved or just the true weight?
This question comes from the so many times that when handling weights with vessel's equipment, as I said, in 2-cranes lift, Ch. Officers complain that the weight is higher than declared.
I started to suspect that the laod cells are actually detecting the (obviously higher) component when the wire is not in the exact vertical.
Ian, maybe you could chime in?
