Selection of the Liebherr models 316 EC-H 12 Litronic and 550 EC-H 20/40 Litronic were key for complete coverage on the 4.9-acre project site. These Morrow hammerhead cranes are a proven product on large scale, multi-crane applications like Oceanwide Plaza. Webcor Concrete is a strong believer in the quality and range of Morrow’s Liebherr products. Features including free standing heights, tie-in spacing, versatile climbing systems and heavy lifting capacities separate Liebherr cranes from the competition.
Above downtown San Francisco rises the Salesforce Tower. A gleaming, glass structure that, when completed, will be the tallest building in the Western United States and the 7th tallest in the entire country. Two Liebherr 542 HC-L Litronic luffing boom cranes were deployed to construct the 61-story office building to a height of 1,070 feet, each with a single part lifting capacity of 19.8 tons.
Both tower cranes were erected in Fall 2015 and are planned to be dismantled by late Spring 2017. Each crane was initially erected with an initial height-under-hook (HUH) of 135 feet. Tower one will rise to 1067 ft HUH with a hook reach of 197 ft and tower two will level out at 1086 ft HUH with a hook reach of 213 ft. Eleven tie-in assemblies connect each crane to the core of the structure.
When completed the 970 ft building will cover 1.4 million square feet and house a 5.4 acre city park with redwoods included. A concrete core is surrounded by uniform steel and a glass curtain wall system. Morrow’s engineering department assisted with the location and positioning of the cranes and tie-in connections to determine the most suitable connection and placement points for the building. Many revisions to equipment application drawings were required during the refinement of the cranes locations and tie-in connections.
Salesforce Tower is a joint project between Clark Construction and Hathaway Dinwiddie for client Boston Properties and Hines. The building is scheduled to open in 2018 at a cost of 1.1 billion USD.
Construction contractor Lend Lease employed two new Liebherr 542 HC-L luffing boom cranes and three Alimak FC 7100-12D construction hoists on the Darling Harbour Theatre project. As part of the greater International Convention Centre Sydney (ICC Sydney), the theatre will seat 8,000 and is specifically designed for large gatherings and entertainment acts. The building features many innovations including seating in a fan like pattern.
Both 542 HC-L’s are configured with a height of 47 meters of tower, with 60 meters of jib on one luffing boom and 65 meters of jib on the other. Three twin Alimak hoists were supplied to the project to deliver men and materials to various sections of the structure. Morrow provided erection and dismantlement services as well as equipment servicing for the duration of the project.
Morrow is proud to provide these two new Libeherr 542 HC-L tower cranes to Lend Lease, one of the largest construction contractors in Australia, for a prestigious project at Sydney’s new landmark.
MoMA Tower is one of New York’s most anticipated building projects this decade, with its innovative design, structural features and location. It is fitting that the crane used to build that tower is the Liebherr 710 HC-L, the lift equipment industries highly anticipated luffing boom tower crane that premiered in North America in late 2015. Sorbara Construction was awarded the high-profile project and sought Morrow’s expertise and innovation in tower crane services to bring this high-profile project to final completion. Morrow provided Sorbara with support, planning, crane erection assistance and field services.
Sorbara was looking for a high-capacity tower crane that featured fast load cycles, a low external profile, and clean operation. The 710 HC-L arrived in North America just-in-time to meet the expectations of contractors in high-density urban environments. Sorbara leased two 710 luffing boom cranes from Morrow’s New York District. The first crane was erected within 17 hours of delivery to the jobsite keeping Sorbara on schedule and under budget for this phase of the project. This crane will have a 148 ft Hook Radius and will climb to 430 feet.
The second crane will be erected during the summer of 2016. This luffing boom crane will have a 197 ft Hook Radius and will climb 711 feet. The second crane will be mounted on a platform outside the building on the 20th floor and top climb to a height of 1050 feet. The first crane will be used to erect the second crane and when the first crane has completed its tasks, the second crane will dismantle the first crane.
Located at 53 W 53rd Street, the MoMA Tower will stand 76 stories at 1,050 ft tall and house 139 luxury apartments. The 710 HC-L will be integral in the construction of the tower, helping place 7,357 tons of reinforcing steel and 48,850 cubic yards of concrete. When completed MoMA Tower will bring 676,000 gross square feet of mixed-use space to downtown Manhattan.
World-renowned architect Jean Novel’s design will be a masterpiece that integrates with the Museum of Modern Art located next door. This integration extends into the Tower where 3 floors are to be designated as MoMA art gallery spaces. General contractor Sorbara is well known in New York for concrete superstructures; 1 World Trade Center Freedom Tower, AOL-Time Warner, 7 World Trade Center and Hearst Headquarters among other projects.
Together the MoMA Tower and Liebherr 710 HC-L will rise above New York’s skyline in a graceful embrace of design, form and structure.

After Mortenson was awarded the NFL Minnesota Vikings stadium project, they contacted our St Louis district office to fulfill their need for a versatile and reliable lifting solution. Morrow Sales and Engineering provided a plan for Mortensen project managers that included a range of tower crane capacities from the 316 EC-H up to the 630 EC-H. In all, 5 Liebherr hammerhead tower cranes were employed on this $1.027 billion dollar project. The stadium is scheduled to open on time for the 2016 NFL season due in part to these reliable machines with responsive support from Morrow service at our St Louis and Chicago districts.
The Minnesota Vikings stadium will seat 65,000 fans with expansion up to 72,000. Fans can also choose from 8,000 club seats and will enjoy the 430 concessions, a restaurant, shops, and the Vikings hall of legends. If you cannot catch a Vikings game yourself then expect to see the stadium highlighted in upcoming Superbowl LII. One unique feature of this stadium will be it’s 60% transparent roof structure made out of a new material called ETFE. This co-polymer resin is an extruded thin film that is extremely light-weight and very durable.
Mortenson is one of our many partners involved in stadium and theater projects from Sydney, Australia to New York, New York. If you have a stadium or theater project planned in the near future then contact your local Morrow district office to develop a plan for success.
Contractors such as GLY Construction, Skanska USA Building, Sellen Construction, Nash-Holland and many others have leased equipment from Morrow during this period of expansion. These contractors relied upon Morrow for erection and dismantlement services, equipment inspection and parts supplies. Seattle’s construction activity continues to gather momentum with many projects slated for 2015 and beyond.
One of the most active companies in the Seattle area has been Amazon.com. Morrow leased equipment to Sellen Construction and GLY Construction, two of the main Amazon contractors, for use on new corporate office spaces. In 2014 alone, Amazon.com added 4 million square feet of office space. The company is planning for an additional 6 million sq. ft. to house an estimated 71,000 employees. These buildings include a 38-story high-rise and the Amazon “bubble building”.
After GLY Construction was awarded the contract for the Allen Institute for Brain Science, they turned to long-time partner Morrow for their lift equipment needs. This new high-throughput science facility will be six stories tall with 245,000 sq. ft. of floor space for laboratory work, high-powered computing, robotic and other automated systems. A Liebherr 420 EC-H hammerhead crane and an Alimak FC 7100-12 construction hoist were used on this project.
Many of the new commercial and residential high-rises utilize either the Liebherr 316 EC-H or 420 EC-H tower cranes, as can be seen in the accompanying panoramic image. The Alimak FC 7100-12 construction hoist can be seen throughout the Seattle-metro area and is a reliable choice for contractors to deliver workers and materials. Contractors are beginning to employ the luffing boom class of tower cranes such as the 540 HC-L and 542 HC-L. As Seattle’s urban core increases in density we expect the luffers to become a common site on the horizon.
Just south of Piedras Negras in northern Mexico is one of the largest breweries in the world. Recently acquired by Constellation Brands, the Piedras Negras brewery is a fully automated warehouse and distillery with state-of-the-art systems that is now undergoing a major expansion. To bring the project to completion is the Liebherr 1000 EC-H, the highest capacity tower crane in its class. Deployed on a job site for the first time in North America, the 1000 EC-H has a maximum capacity of 88,200 pounds (40,000kg) and a jib length of 262 feet (80m).
Contractor Ziemann International opted for the new 1000 EC-H to handle the large loads in the construction of the breweries additional tanks and warehouses. Production will increase from 10 million hectolitres to 20mhl making this brewery one of the largest. Among brands produced at the plant are Corona, Corona Light, Negra Modelo and Modelo Especial.
The automated warehouse was built by System Logistics with Sidel providing the line conveyors and robotics for packaging. Ziemann International was responsible for the design of the plant and equipment. Constellation Brands is an S&P 500 Index and Fortune 1000 company with more than 100 brands in their portfolio, sales in approximately 100 countries and operations in approximately 40 facilities.

With hyper-demand for mobile devices increasing daily, the world’s leading manufacturer of microchips has embarked on an estimated $6 billion expansion of their Hillsboro campus. This expansion centers around the D1X research factory which will house the state-of-the-art equipment used in the manufacturing of ever smaller chips in mobile computing. To meet their 2015 production start date, several Portland-area construction contractors turned to Morrow to handle both phases of development.
Hoffman Construction Company worked with Morrow Engineer, Daryl Hicks, to help coordinate placement of their five Liebherr 630 EC-H 20 Litronic cranes. With these five Morrow-supplied cranes, Hoffman was uniquely challenged with application and deployment of their equipment.
“The hardest challenge was finding configurations that would allow all of the cranes to clear the buildings as well as provide adequate crane to crane clearance,” explains Daryl. “Hoffman required a 20 foot minimum vertical clearance between cranes. Application planning took a number of iterations before project requirements were satisfied.”
Howard S. Wright Constructors used a 630 EC-H 20 Litronic along with a 316 EC-H 12 Litronic to complete their area of the site. These cranes, together with an Alimak FC 7100-12D construction hoist, provided an efficient means to deliver materials and personnel. Turner Construction will also employ this strategy of coordinated crane and hoist delivery vectors. Together with a Liebherr 100 LC, used by Ness & Campbell Crane, will make for a concerted effort unprecedented in scale for private industry in the Pacific Northwest.
