Leer is a fence that no modern boat can do without. Why is this so, and not otherwise, what function does this attribute have and how to make sure that its installation does not hit your pocket hard? All this - below.
What is a handrail?
The birthplace of the word is Holland. Initially, a lifeline was a tightly stretched cable along which you can move during bad weather conditions. Currently, such a fence not only provides security, but also carries several other functions.
The primary task is to ensure the safe descent and ascent of passengers on board the vessel. Many are embarrassed by the small height of the fence, but if a person slips, the handrail will be able to prevent him from falling.
Foul weather or sudden movements often increase the risk of loose luggage going overboard. And the presence of a railing will not allow this to happen.
The handrail is also a significant space saving, because the fastenings of modern accessories (spinning holder, table, etc.) for boats are designed for the presence of a handrailpipes.
Views
There are a huge variety of railings that can be divided according to:
1. From installation type:
- stationary;
- collapsible;
- temporary.
2. From Installation Location:
- ship;
- road;
- decorative and protective;
- balcony;
- roofing;
- stairs.
3. From function:
- protective;
- safety;
- signal;
- guide.
4. From installation method:
- combined;
- welded;
- reference;
- mounted.
Standard raw material for the manufacture of a vertical railing element is the most durable structure: pipe, profile, channel, etc.
The simplest ship handrail is an ordinary cable connected to the boat by means of a holder. The use of this type is considered the most suitable for those cases where everything depends on the mass, for example, when it comes to a sports yacht.
But it is better to equip a motor boat, boat or yacht with a metal fence. The most common material is aluminum or stainless steel.
Homemade handrail
If the purchase of a professional lifeline is very inappropriate at the moment, do not despair. This attribute can be made independently. All you need is to buy a pipe, rack bases and a few fasteners. Required tools are a drill (to drill holes) andgrinder (to cut pipes).
The rail is a very important detail on the ship, so you should not start work without a sketch. The most common size (if the length of the vessel does not exceed 7-8 meters) is a pipe, the diameter of which is 25.4 mm, less often 22 mm. In addition, you need to purchase 2 types of fittings: one is needed to connect the pipes to each other, and the second - to attach the pipes to the ship's hull.
Types of rigging
"Ship's rigging" is a phrase that can be used in relation to any rigging or rigging of a single mast, sailing or any kind of lifting work.
Fixed rigging on a large ship is provided with steel and iron cable with a long service life, and on a small one - synthetic or tarred hemp. Ship rigging also calls for short link chain as it provides much more flexibility.
For the movable option, hemp, flexible steel or synthetic cable is suitable. A sling or chain can be used in conjunction with a lifting device (elevator, crane, hoist or conveyor) needed to lift a large load.
Rescue equipment
When going to sea, one must adhere to an immutable law, no matter what happens, the most important thing is to save human life. The life-saving equipment used on the ship can be individual or group.
Personal life jacket and life jacket should becalculated for each member of the team and for each passenger.
Any lifeboat primarily refers to a group facility. For a very long period, she was an open rowing boat. Currently, wood, metal or plastic is used for its manufacture. A modern lifeboat has several airtight galvanized air boxes that require corrosion-resistant sheet steel.
Large lifeboats are usually equipped with engines, and the latest models are even equipped with closed quarters for victims.
The navy has recently been increasingly using plastic lifeboats with a capacity of up to 33 people.
Closed type This device is supposed to have a hatch with a waterproof cover. In such a boat, a person is not afraid of fire, smoke, or heat, or even a surface covered with burning liquid fuel.
A lifeboat for a tanker must be powered, and its speed cannot be less than 6 knots. Raising and lowering is carried out by means of a gravity davit equipped with an electric winch.
Structure of railings
The place where the wire rope will be located should be determined during the design of the vessel. The characteristics and design of the handrail are described in detail in GOST 5.2124-81.
The height of such a design must be at least 110 cm.rack connections are best used with longitudinal jumpers or a special mesh.
The railing must be continuous and encircle the entire deck. The gap can only be made if it is necessary to install special equipment. The passenger exit/entry area must be equipped with a removable chain guard.
The handrails should be fixed in such a way that there is no more than 45 cm between them and the edge of the board.
About altitude and safety
Reliable railing should perform many functions, but the most important thing is that the standard load is observed and human safety is ensured. So, the handrail of the fence should not be afraid of a load of 400 N / m.
If we are talking about a safety modification, then the value of the permissible standard load increases to 700 N/m.
The height of the safety fence varies depending on the application and the materials used.
Storm line
Without a ship ladder, it is impossible to conveniently and safely enter the ship and leave it, as well as access to a room or workplace located on any deck.
Storm lines are needed in order to ensure the safe movement of personnel during a storm overboard.
If a ship can choose a tropical area as a base, then during the stay, an awning device is installed on it. The canvas awning is pulled over the tent rails.
