Canton crane的意思|示意

'

Canton cranes are large, old-fashioned ships with two or three masts and low, flat sterns. They were the workhorses of the shipping industry in the 19th century, used for carrying large loads of timber, coal, and other items. The name “canton” comes from their original use in the Canton Province in China, where they were used extensively for cargo transport.

Canton cranes can still be seen in action today, often used to carry heavy items such as gravel, rocks, and logs between ships. They are also used to load cranes on larger vessels. The hull of the canton crane is usually made out of wood, while the masts are made out of metal.

On a canton crane, the masts are set close together, allowing them to act like a single unit. The tops of the masts often have lugs or blocks attached to them, which allow for various manoeuvres. The sails are also set close together and connected to a winch. This allows them to be adjusted to create the most efficient amount of thrust.

The canton crane is powered by either a jib sail or a sprit sail. The jib sail is a triangular piece of sailcloth that is attached to the mast and runs from the top of the mast to the bottom of the boat. The sprit sail is a square piece of sailcloth that is attached to the lower portion of the mast and is used to increase the thrust of the canton crane.

Canton cranes are used in modern shipping and can be used to transport both heavy and light loads. They are capable of operating in shallow water and can move large amounts of cargo quickly and efficiently. They are also used to load vessels in ports and can be used to launch boats. While they are not as popular as they once were, canton cranes can still be seen in use today.
