The vessel is typically fitted with two Gantry cranes for self-loading and unloading, with a typical SWL (safe working load) between 30 and 80 tons.Different equipment is connected to the gantry crane depending on cargo type as vacuum clamps for paper, unihook for unitised cargo, container frame and grab for bulk cargoes.
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.
The Guinness World Records state that Taisun holds the world record for "heaviest weight lifted by crane", set on April 18, 2008 at 20,133 metric tonnes (44,385,667.25 lb) by lifting a barge, ballasted with water. [3] However, it was surpassed by the Honghai Crane when the new crane was completed in 2014, with a lift capacity at 22,000 tonnes. [5]

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).
