Abstract: A mounting socket and method for removably attaching a platform supporting davit to a rooftop. The mounting socket includes a folding handle and wheels permitting easy transportation from a storage location to a position near a compatible building supported mounting pedestal. A pair of fixed hooks formed by the socket engage a pair of holes formed by the platform. The socket includes a hollow cavity adapted to receive the davit. As the socket is rotated into vertical position, a locking clamp having movable hooks engages the platform and a secondary locking lever acts to ensure that the locking clamp remains in a locked position on the pedestal. A davit locking pawl prevents inadvertent removal of the davit from the socket when the socket is in the vertical position.

Abstract: A tension sensing device for scaffolds suspended by at least one hoist cable is described. The tension sensing device generally comprises a support structure adapted to be secured to the scaffold and having guide means for directing the hoist cable through the device, lever arm means for sensing the tension on the hoist cable, and switch means for detecting a slack cable or a strained cable condition. The support structure includes a cover plate assembly with at least one section of the cover plate assembly constructed from a transparent material so that the tension on the hoist cable may also be visually observed.
