The Goupitan shiplift ( simplified Chinese: 构皮滩升船机; traditional Chinese: 構皮灘升船機; pinyin: Gòupítān Shēngchuánjī) is a boat lifting system on the Wu River, a tributary of the Yangtze River in Guizhou Province, southwest of China. A system of three boat lifts supplements the Goupitan Dam in order to provide shipping ...
Gin pole derrick. A gin pole derrick (also known as standing derrick or pole derrick) is a derrick without a boom and with single tower or mast supported by four guy wires (two side guys, a fore guy and a rear guy). Its guys are so arranged from its top as to permit leaning the mast in any direction. The base of the tower is hinged and the top ...
The liftboat Kaitlyn Eymard was built in the US by Conrad Industries in 2002. A liftboat is a self-propelled, self-elevating vessel used in support of various offshore mineral exploration and production or offshore construction activities.

Today the boat lift is too short for some barge trains which must be separated to pass the lift. The lift is running near to its capacity with about 11,000 boats passing through each year, [1] so in 1997 the decision was made to build a new, bigger lift. The Niederfinow lift is a popular tourist destination with about 500,000 visitors per year. [1]
Topping lift. The topping lift (more rarely known as an uphaul) is a line which applies upward force on a boom on a sailboat .

The tensioned portion of the rope would fasten the ship to the quay, hoist a foresail, lift a spar into position on the mast or to transfer cargo to or from a dock or lighter. A capstan is a vertical- axled rotating machine developed for use on sailing ships to multiply the pulling force of sailors when hauling ropes, cables , and hawsers .
The VB-10,000 is a heavy-lift twin- gantry catamaran consisting of two truss space frames atop two barges. The design was derived from Versabar's earlier VB-4000 (aka Bottom Feeder), [1][2] which was developed to clear debris from toppled oil drilling platforms in the Gulf of Mexico. Instead of sending divers to section the wreckage into pieces ...
