Davit column
The davit column is an assembly of an inner column, an outer column and a self-braking worm gear unit. The self-braking properties of the worm gear guarantees that the davit is kept in position ever under extreme list and trim conditions.
Standard the SCM-L davit is delivered with a fixed inner column which should be flanged onto a counter foundation/pedestal.
Optionally the davit can be delivered with a fixed outer-column. The main advantage of this type of column is that manual slewing can take place from a fixed position on deck.
