## Abstract

The invention provides a system for managing operations on a peripheral surface of a building. The system includes one or more cables wrapped around the peripheral surface of the building. Further, the system includes one or more wheeled devices capable of moving on the peripheral surface of the building. The one or more wheeled devices are operatively connected to the one or more cables. The one or more wheeled devices and the one or more cables are capable of moving on the peripheral surface of the building as an assembly. In addition, one or more instances of the assembly are operatively connected to each other.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The system of claim 1, wherein the at least one hydraulic cylinder is configured to angularly move the first wheeled device away from the vertical peripheral surface of the building with respect to the second wheeled device while at least one of said wheeled devices is secured on the building.

### Claim 3 (depends on 2)

The system of claim 2, wherein the at least one of said wheeled devices is secured on the vertical peripheral surface of the building is secured by tightening the cable.

### Claim 4 (depends on 1)

The system of claim 1 further comprising a holding member coupled with the cable, wherein the holding member is capable of holding one of a rescue cable and a hose.
