What are Marine Cranes Used For?

Marine cranes are used to ease heavy lifting. It facilitates the maneuver of tons of equipment and cargo from one place to another. Here are some of the marine crane applications:

  • Deal with ship-to-shore work or erecting oil platforms offshore
  • Used for various hoisting operations
  • Moving equipment on the seabed
  • Submerging or recovering materials from the ocean
  • Maneuver materials around the deck
  • Transferring materials or personnel from ther marine vessels, barges, and structures.

What are the Types of Marine Cranes?

The following are the various kinds of marine cranes suitable for offshore and marine applications:

Gantry Marine Cranes – The biggest type of crane. These cranes are several stories tall. It is utilized in loading/offloading shipping operations. Gantry cranes can effectively transfer cargo on and off ships dockside. It has a design which is the operator’s cabin is on the top end of the crane. It is suspended from the trolley.

Telescopic boom crane – It can be hydraulic extended. This crane retracted without a knuckle function.

Overhead Jib Cranes – It uses horizontal pieces such as a jib or boom. This supports a moveable hoist. A jib or boom is permanently fixed to a wall or a floor pillar. Jib cranes are used in offshore drilling industries, lifting materials to different floors, construction sites on the tops of buildings, etc.

Stiff boom crane – specifically made for general cargo handling. It can be utilized on offshore units and ships.

Knuckle boom crane – Used on fixed platforms. It is found on vessels with a large deck area. This has lesser joints thus easy to maintain.

Foldable telescopic boom crane – It needs minimum deck space. This crane ensures constant torque moment. It reduces the pendulum effect’ of the load.

What are the Features of Marine Cranes?
  • High-quality rigging equipment
  • Constant Lifting Capacity
  • Meet the safety standards
  • Handle various heavy weight loads
  • Meet extreme environmental conditions of the marine industry
  • Can be designed according to customer specification

What are the Key Factors to Consider When Choosing a Marine Crane?

It’s important to consider some factors in choosing a specific type of crane. Some are the following:

  • Nature and environment of the ocean – Weather and bottom suction can affect marine crane functioning. It also simulates material handling capabilities. It needs great care and experience to safely and efficiently operates marine crane in water.
  • The impact of each piece of cargo will have on a ship’s listing behavior
  • Stress and load conditions
  • Marine crane manufacturer – select manufacturer wisely to assure smooth operations. Consider all application-specific requirements and cooperate well with your provider.
What are the important parameters for marine cranes?

Whether it is a marine crane, a port crane or a platform crane, it mainly includes the following performance parameters, such as lifting weight, lifting moment, working radius, lifting height, working speed, self-weight and other indicators.
These parameters indicate the working performance, technical indicators and economic indicators of Marine cranes, The above are also the technical basis of crane design and the main basis for users to choose cranes.

What is the lifting moment of marine crane?

The lifting capacity of marine crane and the corresponding working radius is called the lifting moment, which is a comprehensive indicator to measure the operating mechanism of the crane.

What is the lifting height of marine crane?

The lifting height of marine crane means the hook travel.we usually design it as 20m, can also customized according to the clients’s requirements.

What is the working range of Marine crane?

The working radius of marine crane means the distance from the crane rotation center axis to the center of the hook, usually measured in the lifting weight state, due to the lifting weight of structural parts and other deformation may occur. Therefore, when the general tonnage product is hoisted, the amplitude is about 0.5 to 2 meters larger than that when it is empty.

How to measure the working speed of marine cranes?

Working speed is a measure of the actuator operating speed , mainly include lifting, luffing, slewing and telescopic speed.

  • Lifting speed: Lifting speed of the crane hook, divided into single rope speed, empty hook speed and full load speed.
  • Full load speed:all expressed in units of m/min.
  • Slewing speed :expressed in units of r/min.
  • Luffing Speed:means the time for Marine crane lifting boom to luffing from horizontal state to minimum working radius of lifting boom,in unit of seconds.
What is the self-weight of marine crane?

The self-weight of the crane is the entire weight of the crane itself when the crane is in working condition. For a crane of the same performance, the lighter weight means that the crane design is reasonable and manufacturing is reliable.

What is the marine crane lifting capacity?

The crane lifting weight value is called the lifting capacity, crane lifting weight parameters are usually expressed in terms of  SWL(Safe Working Load).
