H&H was contracted for complete system inspections on two movable gantry cranes (100 and 30-ton capacity) in the Robert Moses Power Plant in Lewiston, New York. The project included in-depth inspection and data collection on the structural, mechanical, and electrical systems of both cranes. Non-destructive testing of critical mechanical components was also performed. Complete structural analysis of 100 and 30-ton gantry cranes was performed to verify conformance with Crane Manufacturers Association of America (CMAA) standards and OSHA Overhead and Gantry Crane Regulations. H&H developed CMAA and OSHA rating inventory for each gantry’s primary structural elements. 2D and 3D models were developed using SAP for each crane for the purpose of performing structural analysis and determining critical stresses. A comprehensive final inspection report was developed, which included recommendations and cost estimates for the rehabilitation of both cranes to satisfy CMAA Class A and OSHA requirements.
