Liftech provided design assistance and review services to American Bridge/Fluor Enterprises (ABF) for procurement of a shear leg derrick. The derrick is used to erect the major components of the San Francisco-Oakland Bay Bridge self-anchored suspension span. The crane with a 100-m boom has 1,700 t capacity at 60 degrees. The crane has two auxiliary hooks with capacities of 100 t and 10 t. The boom is configured to lay down for transport within the USA river system.
Global Rigging & Transport, LLC (GRT) was retained to relocate four concrete tunnel sections within the Round Mountain gold mine facility in Nevada. Each tunnel section, weighing up to 1,100 tons, was lifted using a special purpose transporter, moved along approximately 1.5 kilometers of the terrain with slopes of up to 5%, and set at the new location.
Liftech designed a crane move system for moving container cranes that was easy to ship and assemble. Liftech designed a modular system with container sized components for shipping. The system can be assembled away from a crane, allowing the crane to continue working until it is moved. The container crane is secured to the system with four pins and lifted for transport.
Bechtel Power Corporation executed the decommissioning of the Connecticut Yankee Nuclear Power Plant. The reactor vessel was removed for offsite disposal. Rigging International was a subcontractor for the reactor vessel removal. Liftech assisted Rigging International and Bechtel Power Corporation. The lifting scheme took advantage of the existing polar crane. A shoring tower provided an additional support for the polar crane during the lift of the reactor vessel.
Barranquilla Container Terminal S.A. (BCT), Colombia, acting as agent for Sociedad Portuaria del Norte S.A., purchased three Kocks ship-to-shore cranes from the Port of Miami. BCT retained Global Rigging and Transport, LLC (GRT) to relocate the cranes.
The goal: reposition a Liebherr Tango lightweight dockside crane. The Liebherr Tango crane is light and flexible. Unlike typical dockside container cranes, the landside legs are pinned at the top. The crane loses stability when its landside legs are not supported by the gantry rail. Liftech successfully designed a scheme to move the light crane safely on dock.
The crane was designed by Krupp, built in Malaysia, and shipped in pieces to Los Angeles. Bickerton Iron Works was responsible for assembling the crane and transporting it from the assembly site to the LAXT terminal. Liftech provided engineering assistance for the assembly of the crane and devised a scheme to connect two barges and roll the crane onto them.
