Post-type for Liftech projects

Treasure Island Ferry Terminal, Treasure Island, San Francisco, California

Liftech provided the structural design of the steel float for a new ferry terminal located at Treasure Island.  The design included the float structure, support and connection to the gangway ramp, guide pile collars to restrain the ramp laterally while permitting vertical motion, access for future battery systems, and berthing, mooring, and access systems compatible with WETA ferry vessels and…

Manzanillo International Terminal Crane Raises, Republic of Panama

Manzanillo International Terminal (MIT) hired Global Rigging and Transport (GRT) to increase the lift height of eight ZPMC ship-to-shore (STS) cranes located in Panama, and potentially for other terminals in Mexico and Chile.  Liftech provided design review for structural modifications to increase the lift height of two STS crane designs.  Earlier, Liftech assisted MIT with the initial procurement of these…

Maher ZPMC Crane Raise, Elizabeth, New Jersey

Maher Terminals planned to increase the lift height of their 2006 ZPMC STS cranes from 120 ft to 165 ft (36.6 m to 50.3 m), an increase of 45 ft (13.7 m), to accommodate larger vessels calling at their Elizabeth, New Jersey, terminal. Liftech helped Maher by providing structural engineering services including reviewing wheel loads and stability, preparing structural and…

Articulated Balance Crane Design

Liftech conceptualized and designed the Articulated Balance Crane (ABC) concept, a design that reduces the weight and wheel loads of ship-to-shore (STS) cranes. Operationally, the ABC functions similar to a conventional STS crane. For stowage, the elongated boom and apex rotate as a unit about hinges near the top of the waterside legs, providing vessel clearance, while the machinery house…

Truss Boom Crane Design

The client operates terminals at a port in southern China and wanted to procure five new super post-Panamax cranes for a terminal with limited wheel load and tie-down load capacity. ZPMC proposed a truss boom and girder design to reduce wheel loads and tie-down loads. Liftech assisted the client by participating in the conceptualization and design of the upper works structure…

Ro-Ro Ramp Design, Matson Navigation, Oakland and Hawaii

Matson retained Liftech to design roll-on, roll-off (ro-ro) ramps suitable for transporting automobiles and light trucks onto and off ships. Liftech provided analysis, design, and fabrication audit of the ramps, which were fabricated in China. We designed the primary structure, the articulation, structures to support the wheeled dollies, and collaborated with naval architects to design the ship interface structure. The ramps latch…
