A deck crane on a ship is a crucial piece of equipment that plays a vital role in cargo operations. It's designed to lift and move heavy loads efficiently.
The maximum load capacity of a deck crane can range from 5 to 50 tons, depending on its size and type. This capacity is critical in determining the crane's suitability for specific cargo handling tasks.
A well-maintained deck crane can operate for up to 20,000 hours without major repairs, which is a testament to its reliability.

Deck Crane Features
Deck cranes on ships are designed with efficiency and safety in mind. They use a braking system that combines mechanical and hydraulic blocking for added control.
The control system of a deck crane is simple and intuitive, making it easy to operate. This is especially important when working with heavy loads.
Sheaves in the center of the jib provide good stability, reducing the risk of accidents. This design feature is especially useful in marine environments where stability is crucial.

A simple hydraulic system is used in some deck cranes, making maintenance and repairs easier. The main equipment is often located in a low-accessible position of the crane's body, which can make it harder to reach.
Sheaves can be easily replaced due to separable bearing housing, reducing downtime and increasing productivity. This is a significant advantage in industries where cranes are used extensively.
Here are some key features of marine deck cranes:
- High loading and unloading efficiency
- High operation efficiency
- Small occupied deck area
- Suitable for loading and hoisting heavy goods
Maintenance and Inspection
Regular maintenance is crucial for the deck crane on ship. It's jointly completed by the driver and maintenance workers during weekly inspections.
The weekly inspection mainly checks the appearance of marine deck cranes, safety status of hooks, retrieval devices, wire ropes, and the sensitivity and reliability of brakes, clutches, and emergency alarm devices.
During daily routine maintenance, operating drivers perform external cleaning, lubricating rotation work, adjusting and tightening parts, and testing the sensitivity and reliability of the safety device through operation.
The daily check also involves checking for abnormal sounds during operation.
Monthly inspections are carried out by the maintenance unit of marine lifting equipment and the relevant personnel of the user department. They jointly inspect the power system, hoisting mechanism, slewing mechanism, operating mechanism, and hydraulic system of the marine crane.
They also check for wear, deformation, and deformation of parts, and look for cracked and corroded parts and components.
Annual inspections are conducted by the professional maintenance unit for ship deck cranes and the company personnel. They test the main technical parameters of the crane, reliability, and safety devices.
The inspection also involves testing instruments to evaluate the technical status of the lifting equipment. Arrangements are made for major repairs, renovations, and renewals after the inspection.

Equipment and Accessories
A deck crane on a ship is a critical piece of equipment that requires regular maintenance to ensure safe and efficient operation. The crane's hoist wire, for example, needs to be inspected regularly to prevent damage.
The hoist wire is typically made of high-strength steel and is designed to withstand heavy loads. It's also equipped with a load indicator that helps the operator monitor the weight being lifted.
Proper lubrication of the crane's moving parts, such as the winch and gearbox, is essential to prevent wear and tear. This helps to extend the lifespan of the equipment and reduce downtime.
Data Logging Standard / Data Logging Advanced
The S-Series Deck Crane comes equipped with a Data Logging Standard "DLS" feature, which automatically records operation data to a general-purpose memory card (SD card).
This feature includes handle operations, operation modes, limit actuation status, and more, providing valuable insights for maintenance and troubleshooting.
Data Logging Advanced "DLA" takes it a step further by recording hydraulic pressure and operation speed, allowing for more detailed analysis and condition monitoring.
This advanced feature also enables periodic performance checks using self-diagnosis mode, helping to reduce life-cycle costs and ensure optimal equipment performance.
By automatically sending and recording logging data on a PC on the bridge of the main ship, S-Series Connected enables the bridge to centrally manage the status of all cranes.
Machinery
Our deck machinery has an established reputation based on over 50 years of performance results.
We offer a range of deck machinery types tailored to different hull forms.
The straight-arm telescopic crane can be used as a 5-ton, 6-ton, 7-ton, 8-ton, and other electric and hydraulic-driven cranes, with a maximum tonnage of 20 tons.
Its working radius spans between 3-20 meters, with 360-degree rotation.
We provide various types of customized products such as food cranes, material cranes, lifeboat cranes, large ship cargo cranes, large dock cranes, container cranes, bulk cargo cranes, and multi-purpose cranes.
Our gantry sea crane has an extendable boom, a lifting rung, a movable bridge, and a cab, making it suitable for full container ships and barges.
The horizontal main beam of the bridge is higher than the containers stacked on the deck, and there's an automatic positioning device for accurate container placement.
The number of gantry cranes on a barge is often more than that on a container ship, and the lifting capacity can reach hundreds of tons.
