This 1968 crane was originally located in San Francisco but has been relocated to Oakland. The “bell-bottoms” are filled with heavy weight concrete for stability. The concrete aggregate is steel punchings. The crane is still productive, outliving its 30-year design life.

Matson Terminal

This terminal is constructed on unconsolidated fill and is at risk of an embankment failure and sliding into the harbor in a large earthquake. Liftech has performed studies on how to improve the seismic performance.

Schnitzer Steel

Berths 57-59 Wharf

Liftech designed the wharf at Berths 57-59 around the year 2000, and assisted the Port in procuring 10 cranes by providing performance specifications, design review, fabrication review, seafastening review, and offload review.

The wharf sections are keyed together using 3-three foot deep replaceable steel beams that will yield in shear during a large earthquake, helping limit the damage to the wharf. This is the first application of such beams.

Berths 55-59 Cranes

These 10 nearly identical cranes have the longest booms in the Port. Liftech assisted the Port in procuring the 10 cranes by providing performance specifications, design review, fabrication review, seafastening review, and offload review. 1

Berths 55-56 Yard Structures

Liftech, working with JWD, designed the various yard structures for the new terminal around 1998.

Charles P. Howard Terminal 8

The terminal was originally operated by Mr. Howard, whose descendants still live in the Bay Area. Legend has it that the articulated boom cranes inspired George Lucas when he conceived the Star Wars At-Ats. Mr. Lucas has since disclaimed that legend. Two of the cranes have been raised approximately 20 feet to clear taller ships. The articulated booms were provided for aircraft clearance requirements. There used to be more low profile cranes at the Port similar to the remaining one at this terminal. Now that the naval base in Alameda has ceased operating, articulated boom cranes and low profile cranes are not required in Oakland and have slowly been removed.

Middle Harbor Wildlife Habitat – Shoreline Park

The wildlife habitat and shoreline park were established as part of the Vision 2000 work and construction of Berths 55-59. The original estuary was wider. The marker was in line with the side of the channel. A lighthouse was located just east of the marker. The lighthouse was moved to 16th Street and was converted to a restaurant.

Ben Nutter Terminal

11 Outer Harbor

Ben was the visionary Port of Oakland executive director who foresaw the viability of containerization. He and the Board of Commissioners made the bold decision to bank its future on containers—a wise and invaluable choice for Oakland, so it is fitting to name this terminal after Ben.

These terminals display a spectrum of crane styles. Some are old and some new, some modified and some original.

When Ben decided to pursue containers, the director of the Port of San Francisco jokingly said, “Ben, you can have the containers, we’ll take the break bulk cargo.” And so they did.

The black A-frame cranes are original cranes installed in the 1960s.

12 Early A-frame Cranes

13 Left Coast Lifter

Liftech participated in the design, review, or both of the original low profile cranes. All have been removed.

Liftech participated in significant portions of the Left Coast Lifter, the large barge-mounted derrick crane that was critical in assembling the new eastern span of the Bay Bridge.

10 XC40 and XC41

These are the heaviest cranes at the Port at 1,500 t. Liftech provided procurement services and the engineering for relocating XC40 to Berths 20-26.

5 Berths 57-59 Wharf Facts 1. The wharf is 3,600 feet long with expansion joints separating it into roughly 600-foot sections. The wharf sections are keyed together using three large steel beams at each expansion joint, designed to yield and dissipate energy during large earthquakes. This is the first time that this design has been used in seismic wharf design. 2. The east end of Berth 59 is designed so a curved rail can later be installed and connected to a future curved rail on the modified Berth 60 wharf. This will permit the sharing of cranes from Berth 55 through Berth 60. 3. The wharf is supported by 1,872 reinforced concrete piles. The longest piles are 168 feet long. They are designed to support vertical forces ranging from 300,000 to 550,000 pounds each or the weight of roughly 100 to 180 cars. 4. The piles are typically 24 inch octagonal in section. The piles in the second landside row are 4 foot diameter hollow cylindrical piles placed every 12 feet. These piles provide a majority of the lateral wharf strength required to resist seismic forces. 5. The mooring bollards and wharf are designed to resist a force of 330,000 pounds or the weight of 110 cars. 6. The mooring fenders are designed to dissipate up to 485,000 foot-pounds of energy during ship berthing. This is enough energy to lift an average car 160 feet in the air. The wharf is designed to resist a fender force of 800,000 pounds or the weight of 270 cars. 7. The crane stops that will be installed at the east end of Berth 59 are designed to resist a force of 600,000 pounds each. If a runaway crane collides with them, the wheels on the opposite side of the crane will lift off the rails before the crane stops fail. 8. The deck was poured in roughly 100 foot lengths. The first pour was on August 20, 2001.

6 Berths 55-59 Crane Facts 1. The height of the crane apex above the wharf is 220 feet, as tall as a 16-story building. 2. With the boom raised, the boom tip height is 370 feet above the wharf, as tall as a 27-story building. 3. The distance from the landside end of the trolley girder to the boom tip is 450 feet. If set on its side, the crane will not fit inside AT&T Park. 4. The crane weighs 2.7 million pounds. This is equal to the weight of 900 cars. 5. The crane is capable of lifting a hook load of 224,000 pounds. This is equal to the weight of 75 cars or 1,500 people. 6. The crane braking system is designed to resist an 80 mph wind. In addition to the brakes, a pin from the stowage system located at the center of each sill beam can be lowered into the wharf. Each stowage system can resist a force of 350,000 pounds, enough to also resist storm wind forces.
