Hi all! I have a project. that is STS crane system for port. My system are 4 motor group. Main Hoist, Trolley, Gantry and Boom.My partner chose transformer for the system. and i have to check. I think some problem. + In crane systemMain motor type choice is continuous S1. But in mechanic calculation the duty is S3. In STS crane, the hoist motor frequently have to increase / decrease speed and braking. I think, when we calculate, we have to calculate is P2=PRMS*1.4. + i don'tknow what the calculations were correct or not? Please help me! Caculation file attached thanks!
