A capstan is a machine that makes it easier to raise a heavy weight by turning a drum. The technology has been around for hundreds of years, including on sailing ships and industrial machines. So, let’s find out more about this marvellous contraption and how it is implemented in today’s industries.

Capstans have long been used by sailors to aid in raising and lowering anchors on ships. Attached to a cross-shaped axle, the drum was easily turned by a handle and could lift heavy anchors so that the ship could be anchored in place. As it developed, the capstan became increasingly more sophisticated, efficient and powerful, becoming a sailor's essential on the high seas.
The concept behind a capstan is fairly basic—a drum is turned by a rope or chain that is wound up around the drum, hoisting heavy objects in the process. The drum is coupled to a gearbox that provides leverage to the tensile force applied to the handle to facilitate lifting heavy objects. Size and style of the drum may vary, with some capstans being small and portable to be used for non-industrial applications and others being large, heavy duty units which are used for massive hauling applications.
In current industries, a capstan is used in industries as diverse as construction and manufacturing, transportation and logistics. You can see them in factories, warehouses and on construction sites moving heavy loads like steel beams, machinery or construction materials. Capstans are also commonly found on the deck of a ship, and help in sailing the ship, and to moor the ship at the port or harbor, but can also be used in other heavy hauling operations, such as to tow a vehicle, or even to move almost any heavy machinery.
When selecting a capstan for an application the weight of the load to be pulled, the length it will need to be lifted and the amount of space available to actually house the machine need to be considered. Various sorts of capstans exist to fulfill distinct preferences and needs of users, including electric capstan, hydraulic capstan and manual type respectively has its advantages and disadvantages. WorkSafe recommends that a capstan be selected to suit the job requirements for safe and effecient operations.
Capstan technology has improved greatly in the 21st century—new materials and designs have made these machines more powerful and easier to work with than ever before. Today, electric capstans are utilized in industries that require accuracy and control, while hydraulic capstans are often selected in heavy-duty applications where larger lifting capacities are required. With developments constantly happening, these capstans are set to further evolve to keep up with the demands of today’s industries.
