About Us

The Exterior Elevator is a new product from Marvin May. Some of his previous products are Power Climber and Astro scaffold hoists, Mayco concrete pumps, Mayco-Waco scaffolding and shoring, Mayco climbing tower cranes, Mayco permanent window washing systems, Tusky and Jumbo material hoists and Mayco workmen’s construction elevators. Marvin has an engineering degree from studies at MIT and the U.S. Naval Academy and a Ph.D. from UCLA.

The Exterior Elevator is a result of the World Trade Center disaster. There was clearly a need for a better way to quickly reach higher elevations. The Exterior Elevator has important applications for many other tall structures, as well. U.S. and foreign patents have been issued.
