How The Exterior Elevator (Xel) Works

The Xel reaches unlimited heights. Like a passenger elevator or ski lift, it has no height limitations. Unlike them, it is transportable. It can quickly be working and then moved to service many different structures.

The Xel uses the structure for support. Since you can’t pull over a building or most structures with a steel rope there are no structural limitations. The winch is on a truck or trailer. The forces on the winch are upward so it doesn’t need outriggers and won’t tip over.

The Xel uses a traction sheave (the same as a ski lift or a passenger elevator) instead of a winding drum to generate its lifting capacity. The sheave can be small instead of the very large drum that would be needed for high structures.

The Xel winch can be breech loaded. That allows a loop of rope to be quickly inserted into the winch at any location on the rope, not just the end.

The Xel winch generates traction from the load. Traction increases as the load increases. This minimizes wear on the wire rope and automatically maintains sufficient traction regardless of the load. Traction winches have constant speed and torque regardless of the height.

The Xel load does not swing freely in the wind as loads hanging from a crane or a hoist swing. Tail line tension will snug the load against the load line until it reaches the desired height. If windy, a fan will push the load towards the structure while the tail line pulls it away, stabilizing the load.

The Xel’s hydraulic drive provides overload and under load protection, precise speed control up and down and dynamic braking. Loads can be safely lowered without power.
