Otis Machine Replacement
Our client had a machine in need of a major overhaul, but were not ready for a full modernization. Tri-State recommended a new Hollister Whitney machine with new hoist motor, cables and shackles. The new equipment was installed, tested and returned to service in 5 days.
We just wrapped up an entire modernization which included a new machine.
