Abstract: A work gondola apparatus is provided with: a work cage into which a worker boards; equipment mounting parts disposed on both outer sides of the work cage; battery-driven elevating/lowering mechanisms which are mounted to the respective equipment mounting parts and which elevate/lower the work cage to a working location by means of cables that are being suspended; and batteries for driving the respective elevating/lowering mechanisms.

Abstract: A work vehicle (1) including a suspended platform includes a work cage (10) to carry an operator, an arm mechanism (60) having a distal end, the distal end movable to an intended position by at least one of a rotating mechanism (30), an extension mechanism (40), or a derricking mechanism (50) installed on a vehicle body (20). The suspended platform (100) includes a support post (70) located at the distal end of the arm mechanism (60), a suspension frame (80), from which the work cage (10) is suspended, mounted on an upper end of the support post (70) to allow the operator to perform an operation above the upper end of the support post (70), and a lift mechanism (90) that raises or lowers the work cage (10) suspended from the suspension frame (80) with a plurality of lanyards (91) to a work position.

Abstract: A squeegee device (10) for cleaning includes a main supporting base (20) in which an opening (24) is formed along a cleaning width direction of a cleaning surface (W), and a pair of squeegees (30) and (40) arranged to extend along the cleaning width direction along the periphery of the opening (24) and formed of an elastic body. Tips of the pair of squeegees (30, 40) are arranged at an angle relative to each other and contact each other in an airtight state, and pressing the tips against the cleaning surface (W) can open a gap between the tips.

Abstract: An automatic squeezee pressing device for pressing a squeezee against a window pane with a constant pressing force comprises a squeezee to be pressed against a window pane for cleaning the window pane, a squeezee moving mechanism for moving the squeezee toward or away from the window pane, a sensor provided in association with the squeezee for detecting pressing force of the squeezee pressed against the window pane and producing a detection output, and a control circuit responsive to the detection output of the sensor for supplying a control signal to the squeezee moving mechanism so as to maintain the pressing force of the squeezee constant.
