Hello. I’m working at horbor, and I’m really curious about the difference of level luffing jib crane and normal luffing jib(single jib) crane. Normally, level luffing jib crane can move horizontally, and hook doesn’t move up and down when horizontal move, than single jib crane. Except this thing, what difference is considered to buy new crane??? What is the merit to level luffing crane??
