For non-perpendicular cranes with lifting arm rotation ability.
A level-luffing crane is a crane mechanism where the hook remains at the same level whilst luffing; moving the jib up and down, so as to move the hook inwards and outwards relative to the base.
How to map
See crane
For cranes running on rails, draw a rectangle that encompasses the outer area of the rails. The work area may be larger due to the boom.
