in the better days if a hiab for example reached its overload it would slowly release pressure and lower to the ground no f**king drama but not with todays machines where you have to either try and press two buttons together and pray your quick enough or it just locks out and won't do anything which is a great safety feature its a lot harder to recover from a mistake today than it was back then and i'm talking from experience of running crane lorry's and having the certificates training etc
