Water Emergency Transportation Authority (WETA) Downtown San Francisco Ferry Terminal Expansion

WETA is expanding ferry service dramatically to accommodate a significant increase in ridership during the past several years. Part of this expansion includes increasing the overall size of the WETA Downtown San Francisco terminal, adding two new ferry gates, and refurbishing the float at an existing gate. The additional gates and more spacious terminal will significantly improve capacity and quality…

Water Emergency Transportation Authority (WETA), Central Bay Operations & Maintenance Facility Design, Alameda, California

This new Operations & Maintenance Facility is the home base for the SF Bay Ferry fleet in the central bay. The facility will be used to maintain vessels operating on the Alameda, Oakland, Richmond, and South San Francisco ferry routes, and to coordinate emergency transportation services during a regional disaster, disruption in transportation, or both. Liftech is the design prime…

Maher Liebherr STS Crane Design Review

Maher Terminals purchased four ship-to-shore cranes from Liebherr. Two of the cranes have a longer outreach and heavier rated load. Liftech provided crane procurement services including a review of the structural design of the cranes and trolleys, as-needed review of the mechanical design, and crane manufacturing audits at Liebherr’s facilities in Killarney, Ireland.

MES Barge Crane for Matson with Rotating Boom and Headblock

Liftech helped design this Mitsui Engineering and Shipbuilding Co., Ltd. barge crane with a rotating boom and headblock for Matson. The headblock hangs from a rotating hoist platform. During normal operations, when the boom rotates, the headblock rotates relative to the boom so that the headblock does not rotate relative to the vessel.

TRP ZPMC Crane Boom Extension

Terminales Rio de la Plata S.A. purchased two ZPMC cranes in 2005 and 2007 for their Buenos Aires terminal. The cranes, with 65 LT capacity, 18.5 m rail span, and 36-m lift height, had a 45-m outreach. Liftech provided engineering services to TRP to extend the outreach by 6 m to 51 m. Liftech initially provided a study, which verified that the calculated wheel loads for the crane with boom extension were within the allowable values, and the modified cranes met the specified stability requirements.

Sydney Low Profile Crane Procurement

Liftech assisted Sydney International Container Terminals Pty Ltd with structural design and review of four post-Panamax ZPMC low profile shuttle boom cranes for their new container terminal across from an airport in Sydney, Australia.

FastNet

Liftech participated with APM Terminals to conceptualize and design FastNet, a crane technology that enables STS gantry cranes to work adjacent, instead of alternate, bays of a large container ship. APMT estimates that FastNet can deliver berth productivity of 450 moves an hour.

POLA STS Crane Portal Frame Fatigue Study

Fatigue cracks were found in the portal beams of Noell cranes at Pier 400, Los Angeles. Cracking had occurred most frequently at the end of an internal stiffener where the portal beam tapered, and at seafastening lugs that remain on the cranes at the portal-to-leg connections. Other cracking had occurred in the main equalizer brackets.
