10.3.5 King Post

The king post is the moving upright part of the structure to which the runway beam and bracing are anchored. It may be in the form of an upright member with journals top and bottom which fit into the bearing brackets and allow the jib to slew (see Figure 10.3.5-1  a) or in the form of a fabricated section with bearing spigots and rollers which perform a similar function on tubular column free standing jibs. (See Figure 10.3.5-1  b)
