Description
Hutter Putter Gearbox Rotor Turning Device – Our Model Number RTD-168
Hutter Putter Gearbox temporarily replaces existing vertical turning gear motors.
Provides additional gear reduction making it more powerful at lower speeds.
Eliminates need for running bearing lift oil to save outage time.
Eliminates crane pin turning and dangerous air motors!
Installs in minutes!
Model Number RTD-168 is our second most popular model. It rotates large turbines with pedestal mounted turning gears. It provides ultra slow speed turning capability and turns without need for bearing lift oil (hand oil instead). Requires removal of existing turning gear motor. Replaces it with Hutter Putter gearbox shown above. Gearmotor installs in minutes and can be done before or right after outage starts.
RTD-168 varies existing turning gear speed from 1/2 down to 1/168th of normal speed. It includes soft start” technology so as to not jar the gear teeth and includes motor overload protection. The RTD-168 package includes gearbox, motor, mounting plate, electrical panel, speed control box, speed control pendent, and safety switch.
Details: RTD-168 Hutter Putter is similar to RTD-12 except it includes it own custom made gearbox that replaces the existing turning gear motor. It is built specifically y for existing turning gears with vertical motors. It plugs into any nearby 460 power source. Includes a safety switch for easy lockout. 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)
- Useable on different makes, models, and sizes of turbines with “built in” turning gears
