Bollard, mooring ring, pre-embedded fastening fittings, etc.
First, the size according to the drawings;
Second, the top is marked with specifications (such as 100KN, 150KN, 250KN, 350KN, 550KN, etc.);
3. After the bolt hole is tightened, the asphalt should be used to prevent corrosion;
4. After the installation of the bollard is completed, the concrete is injected into the shell;
5. The surface requirements are smooth, and both are coated with red dan or Zhu Dan anti-rust paint;
Bollard It is a facility for ship mooring installed in the superstructure of the dock. The bollard is generally made of a metal material and is named because it has a column shape.
The bollard is designed and selected according to the berth capacity and the structure of the wharf to meet the requirements of safe, reliable and easy to use for the docking, berthing, mooring and turning of the ship. The bollard consists of a casing, a bolt, a nut, a washer, an anchor plate, and a core packing. Bollard column cast iron (HT200) and cast steel (ZG230-450), specification model: 50KN-2000KN
According to the purpose, there are common bollards, storm bollards, test train bollards, etc.
The position of the center of the common bollard is generally about 0.5 to 0.8 meters from the front line. It is too close to be easily hit by the ship when it is separated from the ship. It is not safe for the cable operation; too late, it hinders the loading and unloading of machinery and damages the cable. For armored and ship repair terminals, because the front edge has facilities such as electrical boxes, it is required that the bollard is slightly farther from the leading edge line, about 0.8 to 1.0 meters.
The storm bollard is used for the tethering of the ship during the storm and is usually located at the rear of the wharf. Some ports have little chance of suffering from typhoons, or ships that do not shelter from the wind during high winds, so there are no storm bollards; in some ports, in order not to hinder the operation of loading and unloading transport machinery, there is no storm bollard behind the pier. Increase the size of the common bollard so that it can be used in high winds.
