The gantry crane holds the record for the heaviest weight lifted by a crane. [3] The amount of wire required to operate Taisun is nearly 50,000 meters or just over 31 miles, allowing it to lift a maximum of 80 meters. Taisun seen lifting the 14,000-ton deck box of the COSL Pioneer drilling semi-submersible.
A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. They can range from enormous "full" gantry cranes, capable of lifting some of the heaviest loads in the world, to small shop cranes, used for tasks such as lifting automobile engines out of vehicles.
VB-10,000 is capable of lifting 7,500 short tons (6,800 t) in a single lift, nearly doubling the 4,000-short-ton (3,600 t) capacity of its predecessor. [ 14 ] Each barge is approximately 300 feet (91 m) long by 72 feet (22 m) in beam, and each barge carries four 1,000 horsepower (750 kW) dynamic positioning thrusters for station keeping without ...
A rubber tyred gantry crane (US: rubber tired gantry crane)/ RTG (crane), or sometimes transtainer, is a wheeled mobile gantry crane operated to ground or stack intermodal containers. Inbound containers are stored for future pickup by drayage trucks, and outbound are stored for future loading onto vessels. RTGs typically straddle multiple lanes ...
Gantry-style overhead cranes of the Hainaut quarry in Soignies, Belgium. An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap.
Some new cranes have a 120-tonne load capacity, enabling them to lift up to four 20-foot (6.1 m) or two 40-foot (12 m) containers. Cranes capable of lifting six 20-foot containers have also been designed. Post-Panamax cranes weigh approximately 800–900 tonnes, while the newer-generation super-post-Panamax cranes can weigh 1,600–2,000 tonnes.
Each crane has a span of 140 metres (459 ft) and can lift loads of up to 840 tonnes to a height of 70 metres (230 ft). Their combined lifting capacity of almost 1,700 tonnes is one of the largest in the world. Prior to commissioning, the cranes were tested up to 1,000 tonnes, which bent the gantry downwards by over 30 centimetres (12 in).
In July 2001, a 5000-ton gantry crane collapsed at Hudong Shipbuilding Group while being erected, killing 36 workers and injuring another eight. It was the first gantry crane designed and built in China. [7] In May 2008, two 600-ton gantry cranes collapsed during a lifting operation, killing three and injuring another two. [8]
