Reactor Room Overhead Cranes
Since reactor servicing cranes often run on circular runways, the cranes are often termed as Polar cranes. Whiting pioneered the concept of a polar crane.
The design of these cranes may also be subject to seismic considerations from earthquakes. In terms of design complexity, there are four methods for determining the forces that may develop from a seismic event:
• Static forces
• Single-mode modal analysis
• Multiple-mode modal analysis
• Time-history analysis
For specific answers to application questions, please contact the Whiting Nuclear Power Solutions Team or call 800-861-5744.
Gantry cranes are adapted to applications where overhead runways would be very long & costly to erect.
Medium/Heavy Duty Cranes
Pre-engineered or Customized crane designs for CMAA classes C, D & E.
Heavy Duty Cranes
Customized cranes for CMAA crane classses D,E & F.
Reactor Servicing cranes sometimes called Polar cranes may handle critical loads and so may be subject to strict regulation by the NRC. They are often also subject to seismic considerations from earthquakes.
