Marine cable is part of the normal operation of the indispensable
As is known to all, Marine cable is normal operation of the indispensable part of the quality of the cable problems, though not threaten the safety of navigation, however, for the safety of the ship on the docks, a narrow waterway is crucial.
So, how do Marine cable specific classification?
In use process need us to pay attention to what problem?
And what machine matters need to pay attention to when buying?
The classification of the Marine cable, Marine cable points from the production process can be divided into: three, six, stereotype, twelve, general cargo ship, the commonly used is a stereotype.
Marine rope made from materials that can be divided into: polypropylene filament, polyester filament and polymer polyethylene, luminous ropes, aramid cord, chemical fiber, nylon monofilament ropes and network, commonly used mainly on general cargo ship or polypropylene filament polyester multifilament cable.
Rope in use process pay attention to the problem: the right to use the cable in addition to operating the sailors and the safety of the ship, deputy raised the guarantee can also lengthen the service life of the cable.
1. Before use, first mate (
Or the second officer (
Carefully check the cable in good condition, a rope to certain parts of the broken ends of excessive wear or large, timely replacement cable, can not afford time to change the process of using try not to let this cable tensile strength of the bear is too big, to prevent sudden rupture.
(2) with LAN personnel must be familiar with oneself will operate the types and characteristics of the cable, targeted operation, such as synthetic fiber rope before fracture will not make a sound, there are no signs can be very intuitive to see, if you made this cable in the cable force, must have good mastering a pull rope bearable, prevent sudden rupture.
(3) listed with sailors and ship must wear safety helmet, gloves, safety shoes, work clothes.
'Should never be allowed to wear slippers and shorts, with listed to bring' a lot of boat of individual ship and sailors do not pay attention to the protection of their own, once appear accidental, cable rupture, huge function in the fracture of the cable head cable rupture strength, speed, threaten their safety.
(4) head (
And the second officer (
At the time of operation stir cable car note.
The practice proved: the cable fracture is mainly due to the continuous impact load.
For this reason, stir the cable car to operating personnel, must be skilled operation, try to reduce the impact load to the cable, reduce cable fault causes for this reason.
(5) with LAN personnel must be familiar with LAN operation involved in the process of gestures and sign language, such as: put, closed, stop, stop, etc.
6. Position requirements: the position of personnel and outboard of the cable with cable section;
All personnel shall not stand in the rope ring;
All personnel shall not stand in the 'rebound' area of the cable.
Is summed up in a ship's mooring operation, has a good seamanship seamen, in a safe working environment, and the use of safety rope, use safety of machinery and equipment, use of safety operating rules, will ship securely attached to the dock.
Marine cable purchase considerations Marine cable is life, this life is often and cable material, processing technology, the use of cable frequency, the use of the cable and the cable's daily associated karma.
Usually the service life is 2 -
In the old cable need to change the new time how we choose safe and reliable, long service life and high quality range?
(1) the choice of materials.
The same thickness of the cable under tensile and wear resistance is small, the cause of this situation is the different material, such as simply improve the tension of the cable can choose polypropylene filament material of the cable, if you worry about rope drag and drop on the deck when the excessive wear, need to add a layer on the outside of the cable of the polyester layer increased wear resistance, 'polyester multifilament' structure is adopted,
Internal is sustain tension polypropylene filament, external is to increase wear resistance of polyester package)
In this process and can increase the service life of the cable material, usually can increase 1 year.
(2) the brand and the selection of classification survey certificate.
Cable is an important safety equipment on board, the international maritime organisation for the supply of Marine cable requirements: must have a certificate of classification society, that is, on the shore personnel (
Usually refers to the crew)
At the time of purchase the cable, must pay attention to the classification society certificate issued by cable manufacturers.
Outside, buying cable brand is also very important, choose a cable manufacturer with a long history is very important to use safety and service life of the rope, small factory production of cable quality closes nevertheless, cut corners on raw material, craft in behind, such cable using hidden trouble on the ship is too big.
Unexpected rupture, besides may cause the ship and terminal berth collision, also is likely to cause casualties.
So, it is important to the quality of the cable.
