Roof-Supported Hoists & Structural Capacity Rating - Concord
Parsways performed a detailed structural assessment and capacity rating of roof-supported manual and electric hoists installed on OWSJs and primary beams within an active manufacturing facility.
The study verified load paths, analyzed concentrated hoist loads, and established Safe Working Load (SWL) limits compliant with OBC Part 4 and CSA S16 structural standards.
