Port of Houston purchased three dockside container cranes from ZPMC for Bayport Terminal. Liftech provided the technical specifications, reviewed the structural and mechanical designs, and provided fabrication support for the new cranes. We also reviewed the manufacturer’s structural maintenance program. Prior to the purchase of the cranes, Liftech provided a study to estimate the crane wheel load and tie-down forces.

WBCT Crane Structural Design Review
West Basin Container Terminal purchased four dockside container cranes from ZPMC for Berths 100-102 at Port of Los Angeles. Liftech provided the technical specifications, structural design and review assistance, and fabrication support for the new cranes. The design constraints for the new cranes presented a unique challenge. The new crane geometry is similar to that of the existing cranes, but the structure is designed to comply with new seismic criteria, which are more demanding for the crane structure.
TECON Brazil Crane Procurement
TECON Santa Catarina built a new terminal in Itapoá, Brazil, and purchased four ship-to-shore (STS) cranes and eleven rubber tire gantry (RTG) cranes from ZPMC in China. Liftech provided crane procurement services including technical specifications; a review of the structural, mechanical, and electrical design of the cranes; and crane manufacturing audits at ZPMC’s facilities.
APL MES Crane Modification and Relocation
APL modified and relocated a late 1980’s MES post-Panamax crane with articulating boom from their Kaohsiung, Taiwan, terminal to their Dutch Harbor, Alaska, terminal. Liftech provided the structural design for modification and relocation of the crane and reviewed the contractor’s work.
Dual Hoist Tandem Lift Crane Procurement
Liftech and McKay International Engineers provide the conceptual design for the mechanism docking the two independent headblocks and for stowing the headblock under the trolley. These cranes have differing designs stemming from our headblock interface concept.
YICT Tandem Lift Crane Procurement
Liftech provided procurement services to assist YICT purchase 30 dual hoist, tandem lift cranes for their mega-terminal in Shenzhen, China. The services included preparing specifications, reviewing the crane design, and reviewing manufacturing and commissioning. Reference: Yantian International Container Terminals Limited Shenzhen, China
VPA PMT Truss Boom Dockside Crane Procurement
Virginia Port Authority (VPA) needed three new cranes for their Portsmouth Marine Terminal. The wharf, with a 50’ rail gage, had limited capacity for supporting gantry cranes of the desired size and capacity. To minimize the wheel load at the waterside rail, Liftech provided engineering services to VPA to assist ZPMC design the cranes with light-weight truss booms.
Esperance Port Authority Hybrid Crane Review
Esperance Port Authority purchased a hybrid crane from ZPMC to handle containers and bulk material. Robert Reid & Associates and Liftech Consultants Inc. provided procurement services.
DP World Vancouver Crane Modification
To accommodate larger vessels, DP World Vancouver raised two MGM dockside container cranes 20’ (6.1 m) and extended the booms 14’ (4.3 m). Liftech provided the crane modification design including new leg inserts, boom girder inserts and bracing, forestay inserts, boom hoist modifications, knee bracing, and stairs and walkways.
SSA Mexico Paceco Crane Gage Change and Relocation
SSA Mexico relocated a 50’ gage Paceco crane from the Port of Long Beach, California, to Manzanillo, Mexico. The crane was built around 1980 and was raised in the late 1980s. Liftech provided engineering to change the gage from 50’ to 55’ and for the associated rigging work. The frame was strengthened for higher wind loads, and new stowage brackets and tie-downs were added.
