DF-496
HEE
The scientific name is Panama's cable hole or bulwark cable guide or mooring pile support ring. The commonly used materials are ductile iron (QT450-10) or cast steel (ZG230-450), and surface treatment is generally divided into two methods: hot-dip galvanizing or paint anti-corrosion treatment. The specific treatment needs to be judged according to the usage scenario.
Main purpose
◆ Core function: Guide the cable to dock/depart at the ship's side, change the direction of the cable, and prevent friction and wear between the cable and the sharp angle of the ship's side.
◆ Installation location: at the deck bulwark, mooring deck.
◆ Applicable scenarios: various types of merchant ships, bulk carriers, oil tankers, warships, engineering ships, especially mooring conditions that require large angle left and right guidance.
◆ Advantages: Large guiding range, sturdy structure, impact resistance.
How to choose the appropriate model
Ordinary merchant ships, large angle guidance → Panamax
Heavy load, high-speed cable winding → roller type
Small boat, compact space → sheep horn style
Anchor chain fixation → Chain stopper
Standard certification requirements → Standard cable guide holes
