BHI Energy - Excel Modular Scaffold
Excel Modular Scaffold is an ISO 9001:2000-certified scaffold staging system that utilizes a patented positive-locking trigger mechanism and locking vertical legs for easy assembly and disassembly without the use of hand tools. Excel is adaptable to virtually every scaffold configuration and increases overall builder efficiency as compared to older style systems such as tube and clamp. Excel is used at nuclear power plants, shipyards, oil refineries, offshore drilling platforms and chemical plant facilities.
Deltak Manufacturing, Inc. is a full-service fabrication facility and the sole manufacturer of Excel scaffold. Deltak specializes in full-service design, development, qualification and fabrication of components for custom applications.
The following two patents for innovative scaffold components have been developed by Deltak for BHI Energy:
Reactor Vessel Head Flange Adapter (RVHFA)
The RVHFA is a lightweight assembly that enables faster and more cost-effective reactor head inspections. It is compatible with existing Excel scaffold components and custom-designed pieces are available to fit your facility.
- Reduces time & dose associated with installation
- Eliminates need for conventional tube & clamp components
- Provides lightweight components that are safely & easily handled
- Enables installation of lead shielding blankets to further reduce dose
- No welding, drilling or bolting to existing head structure required
- Plastic-covered inserts protect the reactor head flange & stud holes
- Eliminates need for any type of support structure from the charging floor
These seismically-qualified components enable scaffold towers, work platforms and lead shielding racks to remain installed on a long term basis in containment, while at power. This approach improves dose savings for shielding evolutions and reduces labor costs, worker exposure and critical path time.
Features & Benefits
- Seismically tested & qualified in accordance with IEEE standards
- Custom components fit areas normally requiring tube & clamp
- Increased flexibility using Excel’s fully adjustable diagonal sway strut braces and telescoping load-bearing trusses, load-bearing horizontal bars and metal toe boards
- Reduced labor time & cost
- Reduced material handling & radiation exposure
- Reduced OSHA-required inspection time
- Reduced critical path time
- Increased safety & efficiency
