The wire rope is an integral part of the Marine Crane. It cooperates with the winch, hook, and pulley to complete the cargo lifting work. It is slightly different from the general wire rope. It must be wound in multiple layers on the drum to withstand repeated bending, wear, and impact. , fatigue, etc, so it needs to have high strength, high load-carrying capacity, good elasticity, resistance to bending and fatigue, etc. It must ensure its stability and reliability in order to complete the lifting operation safely!

What kind of wire rope is used for the Marine crane manufactured by OUCO?
The twisting methods of steel wire ropes are divided into right-handed alternating lay, left-handed alternating lay, left-handed mutual twisting, and right-handed mutual twisting, for cranes. There are two types of steel wire surface treatment: smooth surface and galvanized. We choose galvanized steel wire rope, which needs to face the harsh corrosive environment at sea, and galvanized steel wire rope can have good corrosion resistance. We all know that marine cranes involve classification society certification, and the selected wire ropes and other accessories must also meet the corresponding certificate, which depends on your certification requirements.
Sometimes, customers have higher requirements for marine cranes, such as more extended wire rope travel or underwater work, then we will choose imported wire ropes according to these requirements, such as the previously customized 1.5T12M folding arm telescopic crane, the hook stroke reaches 150 meters, this one uses ultra-fine anti-roll imported wire rope, so as a customized product, we will consider the customer's requirements and operating environment to give a good solution!
Relevant standards for marine crane wire rope
Europe and the United States are ahead of us in the development of hoisting machinery. The European Union`s standard system for steel wire ropes has always been relatively complete. Now, with the continuous improvement of my country`s hoisting machinery production technology, the quality requirements for steel wire ropes are gradually increasing. It perfects the standard specification of China's steel wire rope for the formwork, and provides a reliable basis for its production, selection and acceptance. The main standards include GB/T 8918-2006 "Wire Ropes for Important Purposes", GB/T34198-2017 "Wire Ropes for Cranes", GB/T33364-2016 "Wire Ropes for Mooring in Offshore Engineering", etc. These standards are aimed at the materials and technologies of wire ropes. Requirements, testing tests, main uses, etc. list detailed standard terms.

Important testing items for wire rope
OUCO marine cranes attach great importance to the selection of steel wire ropes, because it is related to the quality of our cranes, and must meet the relevant standards and meet the requirements we need. It is understood that these steel wire ropes need to undergo the following important testing items, all testing All projects are carried out in strict accordance with various standards.
The steel wire rope is mainly tested according to the following aspects
Appearance dimensions
Mechanical properties
Chemical composition
Corrosion performance
Plating performance
The maintenance of the wire rope of the marine crane is very important
Regarding the use of wire ropes, we will remind customers to pay attention to the maintenance of wire ropes. When using cranes at sea, corrosion is the main cause of damage to wire ropes, and lubrication is the best way to maintain wire ropes. The better the lubrication work, the better the use of wire ropes. The longer the service life, the maintenance personnel must regularly check the status of the wire rope during use, do a good job of regular lubrication, and record and report problems in time.
