Span 7.5~35m Nuclear Polar Cranes For Fuel Assembly Reactor Head

Nuclear Polar Cranes For Fuel Assembly Reactor Head

Information

Polar cranes are used for fuel assembly purposes and reactor head removal and replacement. Used to handle multipurpose lifting needs, polar cranes are comprised of a main hoist, auxiliary hoist, maintenance jib crane, and containment inspection man lift. These cranes can perform various maintenance and operational duties while ensuring optimal quality and safety. Polar cranes operate on a circular runway located near the spring line of the containment/reactor building. These cranes are primarily used to removal and replacement of the reactor head, as well as during the refuelling outages.

Nuclear polar cranes is designed for multipurpose usage that maximizes operational capability by combining numerous lifting features into a single compact and weight-efficient trolley. The design improves productivity and reliability by providing four primary lifting systems:

Main Parts

• Main Hoist and Auxiliary Hoist - Perform typical plant maintenance and operational functions
• Maintenance jib crane - Provide lifting capability during maintenance operations
• Containment inspection man lift - Inspecting and maintaining the containment dome
