EWEB Carmen Powerhouse Gantry Crane
The Carmen-Smith powerhouse has been servicing the surrounding community with hydroelectric power since 1963. The Eugene Water & Electric Board (EWEB) recently overhauled the aging gantry crane necessary for moving large equipment in and out of the powerhouse. Coffman provided structural, mechanical, and electrical engineering for the 150 ton gantry crane for phases I, II, and III of the modernization project. In phase I, Coffman provided evaluation and documentation of the current condition of the gantry crane and prepared concept designs to modernize it. Additionally, Coffman prepared preliminary electrical load calculations, collected commercial product data, produced a CAD solid model of each crane incorporating the recommended new components, interviewed and solicited pricing information from vendors, and provided the most current controls upgrade recommendations supplemented with form, fit, and functional analysis of the new equipment. Phase II included the preparation of final specifications and drawings to modernize the gantry crane. In Phase III, Coffman acted as Owner’s Representative performing construction administration.
