The handrail handle on the deck of a ship is one of the indispensable safety facilities on board. It not only provides safety support for the crew and passengers, but also plays an important role in bad weather conditions. This paper will introduce its design principle, material selection, installation location and maintenance in detail.
design principle
Safety and practicability are the primary considerations in the design of ship deck handrail handles. Ergonomics should be fully considered in the design to ensure that users can easily grasp and effectively support their bodies in case of slipping or imbalance. In addition, in order to adapt to the particularity of marine environment, such as salt corrosion, wind and wave impact, etc., strict requirements on corrosion resistance and strength are needed.
Material selection
Commonly used materials include stainless steel, aluminum alloy and plastic composite materials. Among them:
Stainless steel: it has good corrosion resistance, is not easy to rust in seawater environment and has long service life.
Aluminum alloy: light weight, high strength, easy to process into various shapes. Its corrosion resistance can be further improved by surface treatment.
Plastic composite material: a new material developed in recent years, which has good weather resistance and low cost advantage.
Installation position
1. Both sides of the main passage: it is convenient for people to grasp and stabilize themselves at any time during walking;
2. Stairs and upper and lower sections: ensure that people have reliable support points when going up and down stairs;
3. Driving indoors and outdoors: It is very important for drivers, especially in bad weather;
4. Lifeboat storage area: In the process of rapid transfer to lifeboats, you may encounter bumps, and handrails are particularly critical.
maintaining
Due to long-term exposure to seawater, regular cleaning is very necessary:
1. Wash away the salt and other impurities attached to the external surface with clear water;
2. Where slight oxidation has occurred, it can be lightly polished with sandpaper and coated with antirust oil;
3. Check whether the joint is firm without looseness, and tighten the screws when necessary;
4. According to the frequency of use and personal experience, formulate a set of reasonable and effective inspection cycle table and strictly implement it.
To sum up, although the handrail handle on the ship deck is only a small accessory, it bears a great responsibility-to ensure everyone's safety during navigation. Through the selection of materials, reasonable layout planning and careful daily maintenance and management, these "little guardians" can better serve the crew and passengers!
