Our Paints And Coatings Standards
Every marine crane we produce uses Jotun paints and coatings that are protective and tacky (sandblasted before painting to enhance paint adhesion).
In addition, we will Check paint thickness to ensure:
Epoxy Zinc-Rich Primer, thickness ≥60 μm
Smooth intermediate coats up to 180 μm
Topcoat with high hardness, thickness ≥ 60 μm
The surface of the marine crane will not be scratched even when touched by sharp objects, and the coating will be free of bubbles, pitting and bottom leakage, meeting the C5M standard for marine use.
Welding Quality Control
OUCO has a team of professional welders who are certified by classification societies. Our marine cranes or grab buckets use fish scale welding technology.
Grinding of dents and welds to ensure quality and appearance of the product.
Non-destructive testing by professional testing personnel or classification societies.
Radiographic or ultrasonic testing, external defects in welds, internal defects or non-destructive testing to ensure that the product quality is absolutely safe and reliable.
Steel Plates We Use
The raw materials of marine cranes are steel plates certified by the classification society, we will choose the appropriate plate according to your needs:
Normal: Q345B (Q355)

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 less 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.
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 other marine vessels, barges, and structures.
- 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
- Bad weather, wind and sea forces;
- Vessel stability and motion
- Adjoining structures, vessels;
- Seabed suction
- Dynamic loading
- Light, noise, spray, etc.
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.
Yes, we can provide you with Hose Handling Crane. Hose Crane is a hoisting machine for handling chemical terminals and oil tankers for loading and unloading oil.
The hose crane includes a hoisting mechanism, a luffing mechanism and a slewing mechanism, supports 360 ° full rotation, and 0-75 ° luffing, the crane adopts full hydraulic drive mode.
Select imported high-efficiency hydraulic working components, it has the advantages of compact structure, easy operation and stable operation.
Hose Crane produced by OUCO is suitable for the hose connecting the lift terminal to the oil tanker. We design according to “Crane Design Specification” GB3811-83, and strictly follow the explosion-proof standard of the chemical wharf.
Send us an inquiry today to customize a cost-effective Hose Handling Crane for you.
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.
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.
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.
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.
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.
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.
The crane lifting weight value is called the lifting capacity, crane lifting weight parameters are usually expressed in terms of SWL(Safe Working Load).
