With a lifting capacity of 660 tons, the Columbia Giant meets the safety requirements for the Atomic Energy Commission heavy lifting projects. The derrick sits on a steel grillage on an existing dock so it can be slid out of the way when not in use. The pipe compression struts are above grade and can be disassembled. The boom and poles can be removed or reused for other derrick or gin pole applications.

4,000 t Floating Crane Design Review, Guangdong Salvage Bureau, China
Liftech provided structural design assistance and review services to ZPMC and assisted them in developing the overall concept and layout arrangement. Liftech also provided preliminary design of the boom tip and typical details of the boom structure, checked member sizes, reviewed design drawings of typical details, and provided suggestions for improvement.
Round Mountain Tunnel Relocation, Nevada
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.
Crane Move System
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.
Nuclear Reactor Vessel Removal, Haddam Neck, Connecticut
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.
Port of Oakland Crane X437 Demolition Plan
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…
BCT Low Profile Crane Relocation
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.
Liebherr Crane Move, Manila, Philippines
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.
Coal Loader Crane Assembly and Transportation
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.
