Abstract
A suspension support device is provided movably on the upper surface of a building for suspending, by means of ropes, an outer wall working machine having fitting and moving members which can be fittedly engaged in a pair of guide grooves formed vertically on an outer wall surface of the building, and lowering and lifting the outer wall working machine along the guide grooves. The device includes a main body, an arm structure connected to the main body, a holding unit connected to the arm structure in a manner to be movable forwardly and rearwardly, laterally and pivotably about a vertical axis and including a pair of holding guides provided at an interval equal to an interval of the pair of guide grooves and being capable of receiving the fitting and moving members, an arm structure drive unit for driving the arm structure to move the holding unit, sensors for detecting the upper edge of the building, and a drive control system for controlling driving of the arm structure drive unit in response to detection information supplied by the sensors. The drive control system controls driving of the arm structure in response to detection information supplied by the sensors to move the holding unit to a position at which the holding guides align with the guide grooves.
