Lifting Equipment

Load Cells Monitor Weight as Cranes Operate on Temporary Shoring Columns

Forty load cells are used to calculate the total mass and center of gravity of tower cranes and lifted loads during the Century City Mall project in Los Angeles.

An early rendering shows a cross-section beneath the traveling crane. This is an initial concept and not accurate to final installation but it shows where the load cells were placed at the top of a sampling of posts on each level.

New Energy Installations Call for Advanced Lifting Equipment

With the surge in alternative energy, Manitowoc Cranes aids in the unique construction of solar and wind farms.

On this project, Mortenson is using a new wind turbine construction method that would not have been possible with previous generations of crawler cranes: It’s building the 194-ton wind turbine assemblies on the ground first, and then lifting the entire unit 300 ft. into the air before attaching it to the top of the tower. This allows assembly of the unit much faster than in the air, reducing the number of picks and the impact of wind on the project.

First-of-its-Kind Electric Luffing Jib Crane Building San Francisco Skyscraper

Building an 802-foot-tall skyscraper in San Francisco required a crane with very high lifting capacities covering a wide working radius and fast line speeds, while at the same time being as space-saving as possible

The WOLFF 700 B luffing jib tower crane — manufactured by WOLFFKRAN and owned by crane rental company Maxim Crane Works L.P. — is the first of its kind in the United States and stands for the launch of a new generation of high-performance, fully electric WOLFF luffing jib cranes on metropolitan high-rise construction projects in the U.S.

Terex Shuts Waverly Crane Production with Short Notice

Terex suddenly shut down its crane factory in Waverly, IA, on Tuesday, planning to move production to Oklahoma, leaving roughly 175 workers wondering what's next

100 UAW workers at the Terex crane-manufacturing plant in Waverly, IA, were given less than an hour notice to vacate the premises when Terex closed the plant down with intent to move production of rough rerrain cranes, truck cranes and boom trucks to Oklahoma City.

New Manitowoc Crawler Crane Cuts Costs on Highway Construction

MLC300 with Variable Position Counterweight system helps cut jobsite prep costs while providing greater lifting capacity during reconstruction of one of Wisconsin's busiest travel corridors

On the site, Lunda is using the MLC300 to lift and set large tub girders that will support a ramp from Highway 45/I-894 northbound to I-94 westbound. The heaviest tub girders weigh approximately 68.5 tons. Lifts are reaching up to 60 ft.

Terex Crane Makes Precise Placement of Steel Bridge Over Train Tracks a Snap

Terex Superlift 3800 with extremely sensitive controls was the right piece of equipment for a bridge installation that required precise placement

The steel bridge structure was delivered in two sections and welded on-site, resulting in a total weight of 77 tons, including the required slinging gear. After the load was meticulously rigged so that it would be perfectly balanced, the power to the overhead lines was turned off and the precision lifting started.

Terex Crane Keeps French Soccer Stadium Construction on Schedule

Sarens uses Terex Superlift 3800 crawler crane to place roof frame on Parc Olympique Lyonnais

The roof supports were placed around the entire circumference of the stadium, and there was limited room for the crane to do its work. 'Management of the free space inside the stadium was a challenge,' says Voeten. “Terex helped us by studying the specific parking conditions for this project and corresponding maximum permissible wind speeds at the various working radii.'
