Putzmeister Formkret Automates Tunnel Lining

Formkret formwork filling system automates the final tunnel-lining process, according to Putzmeister America.

The automated system is regulated by a set of two-way valves integrated into the formwork structure and connected by a single delivery line that links the entire system in sequential rows. It reduces the need for manual work, bringing safety and speed to the process, the company says.

“Putzmeister is working hard to continue to expand tunneling equipment that meets the needs of our customers,” said Bob Harmon, sales manager in shotcrete technology, in a prepared statement. “The Formkret is something we, as a global company, are very excited about. Automating this process makes a safer environment for our customers and advances mining technology.”

The process reduces workforce-related costs by up to 60 percent along with streamlining project timelines, according to the company.
