About this file
This document is a technical specification sheet for Ross Shaft Load Envelopes, Revision 5, dated May 06, 2025, detailing lifting capacity specifications for various cage configurations at Fermi National Accelerator Laboratory (FNAL) for the LBNF/DUNE project. The document provides comprehensive load envelope details for three primary configurations: Single Deck Ross Cage, Slung Load Envelope Double Deck Ross Cage, and Transport Cage & Lifting Adapter Load Envelope, with precise measurements in both imperial and metric units.
Each configuration includes specific lifting capacities, dimensional constraints, and operational notes. The Single Deck Ross Cage has a lifting capacity of 12,500 lbs with dimensions of 11 ft 10 in length, 4 ft 4 in width, and 10 ft 0 in height. The Double Deck Ross Cage has a 13,000 lbs lifting capacity with expanded height to 22 ft 5 in. The Transport Cage and Lifting Adapter have even more significant capacities, with the Transport Cage rated at 18,500 lbs and dimensions of 4 ft 0 in length, 3 ft 6 in width, and 45 ft 0 in height. All specifications include notes about payload limitations, rigging allowances, and contact information for FNAL LBNF/DUNE Rigging Lead Jace Stocker for items outside standard load envelopes.
