Safe slow variable speed turning for turbines 50 MW and larger
For all turbines with pedestal mounted turning gears with horizontal or vertical motors
Eliminates crane pin turning and dangerous air motors!
Can be used on Westinghouse removable bull gears! Extra bolting sold separately.
Installs in minutes!
Model Number RTD-12 is our most popular model. It rotates turbines with pedestal mounted turning gears. It varies existing turning gear speed from 1/2 down to 1/6 of normal speed. Includes soft start” technology so as to not jar the gear teeth and includes integral motor overload protection. Can be used on Westinghouse units with spacer type bull gears. (extra bolting is sold separately).
Details: RTD-12 Hutter Putter electrically connects to existing turning gear motors. It plugs into any nearby 460 power source. Includes a safety switch for easy lockout. No mechanical alterations are required. It operates by a portable controller that goes anywhere along the turbine centerline. No expertise is required to operate. Speed can be varied “on the fly”, making it ideal for critical path outage tasks such as coupling alignment checks, coupling reassembly, in-place rotor inspections, and balance weight installation.
Cost Saving Benefits of using a Hutter Putter:
- Slashes coupling alignment and assembly time
- Improves worker safety by eliminating the overhead crane from rotor turning
- Improves worker safety because it can be controlled right at the coupling being worked on
- Improves worker safety by eliminating dangerous air motor and pony motor rigs
- Provides backup to turning gear MCC (Palo Verde saved millions in downtime during a startup)
- Usable on different makes, models, and sizes of turbines with “built in” turning gears
