Our Mission

SafeHoist is committed to using its knowledge and state-of-the art technology to improve the safety and efficiency of hoisting in the United States and around the world.

Our Story

Caesar Migratti, grandfather of SafeHoist's founders, started work as a miner in the copper mines of upper Michigan. He later operated one of the first Ingersoll-Rand continuous mining machines in the coal seams of Acme, Wyoming. Throughout his life, Caesar related many stories to his family of the importance of mine safety and efficiency.

SafeHoist, a US company, has developed state of the art devices to monitor hoist and conveyance safety and efficiency. The development of these products is a result of extensive shaft safety monitoring and productivity research in some of North America's deepest shafts.

We employ the latest technology using components and products from companies such as DIGI® and National Instruments®. Extensive field trials have been completed in cooperation with several major underground mining companies, such as Hecla and Stillwater. The RopeRanger® and SkipRanger® products allow mine owners and operators to capture and analyze critical safety and efficiency information from mine hoist rope and conveyance. The Company believes that the hoist rope and conveyance are common threads providing dynamic links and real time sampling vehicles for the shaft and hoisting system. Our sensors detect and record data revealing the health of the shaft – in real time, and on every trip.
