Abstract
A davit arm holder 30,50 for a davit arm 11-18 for suspending lines 4 from elevated heights by mounting the davit arm 11-18 on a structural substrate 1. The davit arm holder 30,50 comprises a base 50 formed from one or more planar layers 52 of sheet material adapted to lie parallel to the plane of a surface of the substrate 1, and an attachment 30 adapted to be fixedly attached to the base 50 and to provide a connection 32 to engage a davit arm 11-18. The base 50 includes an outer layer 52 and at least one inner mount 60. The outer layer 52 has a plurality of first engagement portions 70 that are radially spaced from a centre point 54 of the base 50. The at least one inner mount 60 is integrally formed with the outer layer 52, is fixedly securable to the substrate 1 and is adapted to space an inside surface 68 of the outer layer 52 from the substrate 1 to form a gap 66 under the outer layer 52. The base 50 is adapted to have a low-profile when anchored to the substrate 1. The attachment 30 is adapted to be releasably engaged to the base 50 by a plurality of second engagement portions 40 adapted to engage the corresponding plurality of first engagement portions 70 by rotation of the…
