What are the classification and technical requirements for cable guide holes? What is your opinion? Maybe everyone has their own
Next, let's also talk about the opinions of Taizhou Wanli Ship Machinery Manufacturing Co., Ltd.
The standard divides cable holes into two categories: closed and open. The overall structure of the closed cable guide hole is closed, making it difficult for the cable to come out when passing through, and suitable for high load or harsh sea conditions; One side of the open cable guide hole is open, making it easy to quickly thread and detach cables, and is commonly used for routine deck operations.
The selection of materials for two types of cable holes should meet the requirements of tensile strength and seawater corrosion resistance, usually using cast steel or stainless steel. The structural dimensions need to match the diameter of the matching cable, and the edges need to be chamfered to avoid wear on the cable.
The technical requirements particularly emphasize the structural stability under dynamic loads. For example, closed cable guide holes need to be able to withstand the impact force when the cable suddenly tightens, while open cable guide holes need to ensure that the cable will not accidentally come out when the ship swings. The welding strength of the installation base of all cable holes also has clear indicators to prevent cracking caused by long-term vibration.
