MAST HEAD FOR A DRAGLINE
A mast head assembly for a dragline comprises an elongated body for connecting to a mast of a dragline. The elongated body includes side plates on opposite sides of the body. The side plates have suspension lugs and chord and lacing stubs for attaching cables from the mast head to the boom of a dragline. At least one of the cord stubs is located above and to the rear of a first chord stub. The chord and lacing stubs are positioned on the side plates so that the maximum stress in the mast head assembly is where the chord stub connects to the original chord. The highest remaining stress is located at the point where the upper/rear chord stub connects to the original chord.
