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.
Port Everglades Low Profile Crane Design
Four post-Panamax cranes were designed to meet specific requirements of Port Everglades, including strict aircraft clearance requirements and efficient structures to withstand hurricane winds. The inclined landside leg significantly reduced the weight. An improved adjustable boom hanger system increased reliability and enhanced boom travel performance.
POLB Crane Procurement
Liftech performed structural design review of Mitsui and ZPMC cranes. Liftech Consultants Inc. and McKay International Engineers prepared the procurement specifications, evaluated technical portions of the bids, and reviewed the designs and quality control documents. Liftech reviewed the design and construction in Japan and China.
APL Crane Procurement, Ports of Los Angeles, Kaohsiung, and Karachi
Liftech Consultants Inc. and McKay International Engineers prepared the procurement specifications, evaluated technical portions of the bids, and reviewed the designs and quality control documents. Liftech reviewed the design and a portion of the construction in Abu Dhabi.
Massport Low Profile Crane Design
Liftech provided the conceptual and final structural design and detail drawings for two post-Panamax low profile container cranes. The inclined landside leg significantly reduced the overall weight, reduced the wheel loads, and allowed for a lightweight boom.
