T-head Bollard Features
“Tee Bollard”, “T-bollard”, this design has a top shaped like a “T”. Hence, the name. Very prominent in many parts of the world due to its simplicity and it gets the job done well up to 300 tonnes. Suitable for steeper rope angles.
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 operations such as ship leaving the dock, berthing, shifting and turning around. The bollard is
composed of shell, anchor rod, nut, washer, anchor plate and core packing. The bollard is divided into cast iron (HT200) and cast steel (ZG230-450), specification model: 50KN-2000KN .
According to usage, there are normal type bollards, storm bollards, trial bollards, etc. Generally, the center of the normal typebollard is about 0.5 ~ 0.8m away from the front line, which is too close, so it is easy to be hit by the ship when approaching andleaving, and it is not safe for the cable operation. Too far behind, hindering the loading and unloading machinery and damagingthe cable. As there are electrical boxes and other facilities at the front edge of the ship-dressing and ship-repairing wharf, itis required that the bollard be a little farther from the front line, which is about 0.8 ~ 1.0 meters.
Storm bollards are used formooring ships during storms, and are generally located behind docks. Some ports don't have storm bollards because there is littlechance of typhoon, or ships don't take shelter in the harbor when there is strong wind. In some ports, in order not to hinder theoperation of loading and unloading transportation machinery, storm bollards are not set up at the rear of wharves, but the size ofnormal type bollards is increased so that they can also be used in strong winds.
