dc.description.abstract The purpose of this project is to analyze the existing field pole lifting device at Manitoba Hydro’s Grand Rapids Generating Station, as well as design a solution to improve the safety and ease of use of the bottom clamp of the device. Our final design addresses the safety risks, through FEMA analysis, to provide a safer design, while mitigating the risk of the design. This report delivers detailed drawings, hand calculations of our design, CAD models of the assembly and FEA modeling validating that the design meets all constraints and limitations. The final design meets all category five needs and metrics, provided by the client, including a total weight of 35 lbs, a total of two workers for installation and operation, and all sizing constraints. The design also decreases the total set up time and installation time because of its decreased weight. The design meets the minimum 1/3 yield criterion with maximum stresses of 22633 psi and 21408 psi for the tusk and distributed loading, respectively. The maximum crack lengths the design can experience in the stiffeners and tusks locations are 0.788 in and 0.315 in, respectively. These crack lengths can easily be detected before they reach their critical lengths and cause failure. The design can also handle an infinite number of load cycles. The design is to be made out of with six different 70WT steel waterjet parts and welded into one assembly to ensure maximum simplicity, accuracy and precision, while minimizing the overall cost of the device. The design’s total cost is estimated to be $3280. en_US
