Cramer Engineering is experienced in designing wood or steel zip line towers. We have worked on multiple adventure parks throughout the country. Typical tower heights range from 50ft to 100ft and with tandem zip lines. Cramer Engineering was hired to design, and value engineer the towers to save money for a design build client. We successfully reduced the construction cost of the zip line adventure park at the Toledo Zoo in Ohio, and saved the client thousands. Cramer Engineering models the towers in Ram Elements for a detailed analysis of the structures with fully loaded zips lines and rope bridges. Cramer Engineering tested and commissioned the towers in April of 2016.
