Hi,
For the design of a gantry crane I need to know what is the normal mode of operation actually used by crane operators. The crane capacity is 25tons, with height of 15m and a total span of 52m and 32m span between the two legs. I would like to know if it is normal for operators to lower or lift the loaded grab while travelling or traversing.
While I feel it is safer to lock the traveling and traversing movements while the grab is in operation, I am not sure that the locking of movement would apply unwanted stress on operators when they want to do simultaneous operations but they can't.
Any advice is appreciated.
