Port of Oakland tenant SSA Marine increased the lift height of four 1999 Port of Oakland ZPMC STS cranes by 26 feet to accommodate the larger vessels calling at the port.
DP World purchased two used Paceco Espana ship-to-shore cranes from a terminal in South Carolina to service 16-wide, 6,500 TEU ships calling at their terminal in St. John, New Brunswick, Canada.
Crane Procurement – Long Beach Container Terminal, Automated Stacking Cranes (Yard RMG Crane) Intermodal Yard Cranes (Wide Span RMG Crane)
LBCT purchased up to 70 ASCs and 5 IYCs from ZPMC. Liftech provided crane technical specifications, structural design assistance and design review, and limited fabrication review services. We also reviewed the trolley structures.
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.
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.
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.
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.
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.
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.
APMT operates ten Noell machinery-on-trolley cranes at their Pier 400 terminal in Los Angeles. The original trolley structure was torsionally rigid. Some of the diagonal members cracked due to warping caused when one wheel is out-of-plane to the other three. Liftech provided design modifications to reduce the stresses in the members due to warping.
