Deck crane maintenance and damage prevention suggestions

In order to facilitate loading and unloading operations and reduce the dependence of ships on the loading and unloading capacity of the terminal, many bulk cargo ships and some container ships are equipped with deck cranes. Compared with traditional single-boom and double-boom cranes, deck cranes are easy to operate, flexible in operation, and can adapt to the operation of various types of cargo. While deck cranes greatly improve loading and unloading efficiency, they are also prone to damage due to their frequent use during loading and unloading. Once a deck crane fails or an accident occurs, it will not only affect the ship schedule, but also cause damage to the ship, machine, cargo, and casualties. Subsequent repairs and treatments require huge manpower, material and financial resources. Next, we will explain the maintenance of deck cranes from the following three points:

I. Maintenance measures

1. Regular maintenance: According to the maintenance cycle recommended by the manufacturer, the deck crane is maintained by replacing hydraulic oil, cleaning the filter element, and checking electrical components to ensure that the equipment is in good condition.

2. Preventive maintenance: For wearing parts and key components, preventive replacement or repair is carried out to reduce the probability of failure.

3. Standardized operation: Strengthen crew training to ensure standardized operation of deck cranes and avoid failures caused by human factors.

II. Management precautions

1. Strengthen the management of hydraulic oil

2. Prohibit overload operation, clean the cooler regularly, and prevent the hydraulic oil from overheating and causing oxidation and deterioration.

3. Engine personnel should strengthen the study of hydraulic professional knowledge and improve fault diagnosis ability and maintenance skills.

4. Pay attention to the pre-job knowledge training of shipping company crew members to eliminate blindness and experience.

III. Loss prevention suggestions

1. Effectively implement the maintenance and care of deck cranes: The maintenance and care of deck cranes cannot be left on paper. The frequency of inspection of the easily worn parts of cranes should be increased. If the wear limit is exceeded, they should be repaired and replaced in time.

2. Conduct safety project inspections before work

3. Strengthen supervision of loading and unloading operations

4. Actively respond to accidents

As the person responsible for the management of deck cranes, daily inspections, maintenance, care, and testing must be careful and rigorous. Details that are easily overlooked are often the accumulation of signs of failure. Only by taking effective maintenance measures can we ensure the safe and efficient operation of the deck crane and provide strong guarantee for the smooth operation of the ship.
