In response to Darwin Port Corporation’s decision to relocate a 1980’s IHI crane to a wharf with a different rail gage, Liftech designed a scheme to change the crane’s gauge from 19.8 m to 25.3 m. The scheme involved extending the existing portal beams by five meters on the land side, relocating the landside legs, and removing the elevator track below the portal beam.

VPA Elevating Girder Crane Design
Liftech worked with VIT and ZPMC engineers to develop the elevating girder crane design. The upper works (including the trolley girder, boom, trolley girder support beams, A-frame, apex beam, and stays) may be hoisted to any of five preset elevations to reduce hoisting time to suit ship sizes. Liftech provided full procurement services for the project.
Matson Paceco Crane Relocation, Oakland to Hawaii
Matson bought two used Paceco cranes from the Port of Oakland for their Sand Island facility. Rigging International transported them by barge to Sand Island. Liftech checked the cranes for the voyage forces, designed the reinforcing for the cranes and the tie-downs to the barge, and checked the barge structure for the voyage loads.
New Century Crane Procurement
Liftech was retained by China Shipping to provide engineering services to procure four dockside cranes. Liftech prepared the technical specifications, assisted with the structural design of the cranes, and reviewed crane design, manufacturing, and commissioning.
VPA Crane Procurement
Liftech provided Virginia Port Authority with crane procurement services including technical specifications, crane design review, and manufacturing review. Liftech also provided engineering consulting with the design of the elevating girder crane whose upper works (trolley girder, boom, A-frames, stays, trolley girder support beams) can be hoisted to one of five preset operational elevations, depending on the ship size, to reduce the required hoist distance and unloading time.
Ceres Halifax ZPMC Crane Procurement
Liftech helped Ceres purchase a 22-wide dockside crane for their 60’ rail gage wharf. The crane has an outreach of 194’ for the future 22-wide vessels. The crane was built by ZPMC in China. Liftech prepared the procurement specifications and provided the design and manufacturing review.
Long Beach Container Terminal Crane Modification
Long Beach Container Terminal wanted to raise five IHI dockside cranes and extend the outreach to accommodate larger vessels. Liftech provided the design of the modifications to Bickerton Iron Works to raise the 1980’s container cranes by 10 feet and extend the boom 10 feet. Two years later, Liftech provided the design to raise the cranes an additional 20 feet for a total of 30 feet lift height increase.
Repair of Damaged Crane Booms
Container crane booms are frequently damaged due to ship collisions. Liftech has been involved in dozens of repairs and provides all aspects of engineering for repairs. Repairs range from rebuilding damaged sections to stiffening damaged sections to heat straightening damaged locations.
Ceres Paragon Terminal Crane Procurement
Nine cranes will operate on both sides of a ship in an indented berth. The cranes will serve future vessels with 22 containers across. Together, the nine cranes are expected to provide a turnaround of 300 containers per hour. Five south cranes will go around the corner between the indented berth and a straight berth.
CentrePort New Zealand Crane Raise
CentrePort needed to raise their cranes to meet increasing vessel sizes. Liftech provided a feasibility study for different raise heights and a design of the modifications to raise two 1970 Vickers Hoskins-Paceco container cranes by 6 meters (20 feet). Liftech also designed a jacking frame for the contractor that allowed them to raise the cranes in less than a week.
