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.
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…
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…
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.
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.
