Liftech provided engineering to demolish the articulated boom Crane X437 at Port of Oakland Berth 37, including review of the associated wharf loads
Power Engineering Construction Co. used their DB Pacific floating crane, a Liebherr LR1300 crawler crane, and a hydraulic mobile crane. The crawler and mobile cranes imposed large, localized loads on the wharf structure.
Liftech’s scope included wharf review for the land-based crane loadings and submittal calculations; development of the dismantling plan including strength and stability review, boom lowering procedure, rigging arrangements and details; and construction support with site visits. The boom removal procedure takes advantage of the articulation linkages that simplified removal by lowering the waterside boom segment to a vertical position.
