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.
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.
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.
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.
APL needed two quay cranes quickly for their operation in Colon, Panama. Liftech helped them convert one crane and transfer both. The Paceco crane on the left in the picture above began life in 1982 at the Port of Oakland on 100’ gage rails. Several years later, it was moved to Seattle. In 1994, Liftech designed a scheme to modify and move the crane to its current location in Panama.
A new client at the Port of Oakland required post-Panamax cranes. The Port had two Hitachi Panamax cranes available at the client’s berth and a Paceco Panamax low profile crane at another berth. The two Hitachi cranes were raised 20 feet.
When it became possible for shipping lines to economically avoid the Panama Canal, ship size increased from 13 containers wide to 17 containers wide. Ships could carry thirty to forty percent more containers. The pictured Mitsui Panamax crane was converted to post-Panamax configuration.
