Northeast Water Purification Plant Expansion Pulley System

Houston, Texas

As part of the ongoing Northeast Water Purification Plant Expansion project in Houston, Stiver Engineering was asked to provide a pulley system to pick up and place 108-inch-diameter pipe sections which weighed more than 20,000 pounds. An I-beam frame was provided to help with the lifting process. Finite element analysis was performed to size the beam and connections. An anchorage design for the frame was also provided using three alternatives that best fit the client’s needs. The frame was designed so the client could easily assemble/disassemble it as necessary.
