How do you categorize marine cranes?

Marine cranes are important equipment used for loading and unloading cargo and other lifting operations on ships. According to different classification standards, marine cranes can be divided into the following categories:
First, according to the structure form classification
Gantry Cranes: Gantry cranes have a lifting arm that spans the ship’s side like a door, and load and unload cargo by moving the lifting arm and hook. They usually have a large lifting capacity and working range.
Jib Cranes: The lifting arm of a jib crane is mounted on a rotating platform, which enables the rotation and movement of cargo. This type of crane is compact and suitable for ships with limited space.
Tower Crane: Tower cranes are similar to tower cranes on construction sites, with the lifting arm towering over the ship, allowing for the loading and unloading of high-level cargo.


Second, according to the drive mode classification
Electric crane: through the electric motor drive lifting and rotation of the lifting arm, electric cranes have the advantages of easy operation, energy saving and environmental protection.
Hydraulic cranes: the use of hydraulic systems to drive the lifting arm, hydraulic cranes have a large force, rapid response, etc., suitable for heavy cargo loading and unloading.
Manual crane: in some small ships, may use manually operated cranes, although the operation is relatively laborious, but the structure is simple, easy to maintain.

Third, according to the use of classification
Cargo cranes: mainly used for loading and unloading goods, including containers, bulk cargo, etc.
Marine engineering cranes: specially used in the field of marine engineering, such as offshore drilling platforms, offshore wind power generation equipment, such as installation and maintenance.
Rescue cranes: used for marine rescue and salvage operations, with special lifting and rescue functions.

Fourth, according to the lifting capacity classification
Small cranes: small lifting capacity, suitable for small ships and light cargo handling.
Medium-sized cranes: moderate lifting capacity, widely used in various types of ships.
Large cranes: larger lifting capacity, for large ships and heavy cargo handling.
The above classification is just some common methods, in fact, the classification of marine cranes can also be based on other factors, such as the structure of the lifting arm, the control mode and so on. Different types of marine cranes differ in design and function, and users need to determine the most suitable type of crane according to the specific needs of the ship, the working environment and operational requirements when choosing.
Regardless of the categorization, the safety, reliability and efficiency of marine cranes are crucial. When purchasing and using marine cranes, it is important to ensure that they comply with relevant international and domestic standards and have been inspected and certified by professional organizations. In addition, regular maintenance and inspection is also the key to ensure the normal operation and prolong the service life of the crane.
