Other crane types, such as gantry or Goliath cranes may have similar capacities, but the jib reach of the ring crane allows them to work over a large area. This ability for a single crane to make lifts over a large area may reduce the amount of other expensive high-capacity plant needed, such as self-propelled modular transporters (SPMT). [6]
Left Coast Lifter made its first lift on the new Tappan Zee bridge in April 2015, [22] a steel-reinforced concrete pile cap which formed part of the bridge's foundation. The massive crane was being used for heavy lifts of large bridge sections, [23] and placed the final steel girder for the new Rockland-bound (westbound) span in October 2016. [24]

The advantage of the box girder type configuration results in a system that has a lower deadweight yet a stronger overall system integrity. Also included would be a hoist to lift the items, the bridge, which spans the area covered by the crane, and a trolley to move along the bridge. The most common overhead crane use is in the steel industry.
The crane can lift 1,000 tons of debris, Maryland Gov. Wes Moore said Friday. But “one of the challenges is that the Key Bridge, which sits on top of the vessel right now, that weight is ...
The floating barge-crane, originally named Marine Boss, was built for Murphy Pacific Marine.The barge was assembled by Zidell Explorations from scrapped ship steel in Oregon [2] in 1966 and fitted in San Francisco with a heavy 500-ton revolving crane made by Clyde Iron Works [3] to perform the heavy girder and deck-section lifts for construction of the 1967 San Mateo-Hayward Bridge.
