I tried to look up the crane signals, unfortunately they were hard to find so as a favor to everyone I have re-posted them here. Interestingly there is no universal signals as signals in USA and UK differ from Australia's crane signaling. From personal experience I dont mind hand signals provided there is a clear line of sight but am not a big fan of the whistles. It is hard to communicate the crane speed required by the dogman when just using whistles and it is easy to mix up signals. Another problem is that building sites are generally noisy, combined with usually being on a main road and a noisy diesel crane as well as guys whistling at the girls walking by it can get frustrating when given whistle signals. :-/
