Abstract:
1. A system for managing operations on a vertical peripheral surface of a building, the system comprising: a first wheeled device; a cable having a first end and a second end; a first reel of the first wheeled device directly connected to the first end of the cable; a second reel of the first wheeled device directly connected to the second end of the cable; a first motor connected to at least one of the first reel and the second reel for tightening and loosening the cable while the cable is completely wrapped around the vertical peripheral surface of the building; and a second motor connected to at least one wheel of the first wheeled device for moving the first wheeled device along the vertical peripheral surface; and at least one connector directly connected to at least one hydraulic cylinder for coupling the first wheeled device to a second wheeled device while on the vertical surface of the building, the at least one hydraulic cylinder capable of directly connecting to a second connector on the second wheeled device and capable of extending and retracting to vary a distance and angle between the first and second wheeled devices; wherein the cable can wrap all around the vertical peripheral surface of the building so that when the first reel and the second reel tighten the cable it securely affixes the first wheeled device to prevent movement along the building, and when the first reel and the second reel loosen the cable it provides enough slack to allow the first wheeled device to move vertically along the vertical peripheral surface of the building via the at least one wheel.
