Crane is a kind of equipment for loading and unloading goods. It has the characteristics of large lifting capacity, convenient operation, impact resistance, good braking performance, safety and reliability, high loading and unloading efficiency and good adaptability to goods.
Hydraulic crane is a kind of loading and unloading equipment widely used on ships. It has the characteristics of large lifting capacity, convenient operation, impact resistance, good braking performance, safety and reliability, high loading and unloading efficiency and good adaptability to goods. More than 1000 hydraulic cranes of various types are used on ships of major shipping enterprises in China, and more than 500 hydraulic cranes of various types are used on ships affiliated to COSCO (Group) Corporation. Hydraulic crane is a kind of ship lifting equipment with high technical content, which integrates electricity, hydraulic and machinery. In the process of use, technical management personnel with certain professional knowledge are required to carry out daily maintenance according to the requirements. In practice, the hydraulic crane has a high failure rate due to lack of proper maintenance, improper operation and use, poor working environment and disrepair for a long time.
The renovation of
hydraulic crane mainly starts from three aspects: first, the research group organizes relevant experts, maintenance management personnel and management personnel of hydraulic crane to analyze and classify the fault types and causes of hydraulic crane, and prepare technical documents with practical value for ship management personnel to implement and continuously improve in use; Second, improve the maintenance and management level of managers by improving their professional knowledge, fault diagnosis ability and maintenance skills, and actively promote proactive preventive maintenance; Third, for 70% of the faults of the hydraulic system are related to the cleanliness of the oil, strictly control the cleanliness of the hydraulic system to keep it within the allowable range.
Most of the cranes at the wharf do not need to be equipped by bulk carriers. It is basically produced by the equipment factory, and its operation modes include: local operation; By the control valve group at the hatch cover; Above hatch cover.
