JIS F2001 Double Bitt Bollard is a type of mooring equipment installed on ships to mooring and towing ropes. It is based on Japanese Industrial Standards, and is mainly designed and manufactured according to berthing capacity and wharf structure to meet the safety and convenience of wharf, mooring, shifting and turning around.
JIS F2001 Double Bitt Bollard is mainly made by welding steel plates and steel pipes. Its appearance has no cracks, no defects or rust that are not conducive to use, and has a good smoothness. The nominal diameter ranges from 100mm to 800mm, and the weight ranges from 18.9KG to 3071KG. Its’ appearance ropes are wire rope, manila and sisal fiber rope, synthetic rope, and so on.
The bollard can withstand use in harsh environments. Due to its dual horn shape, it can accept multiple mooring ropes. Because it is subjected to a lot of force during use, its base is required to be very firm. In order to prevent the rope from slipping off the pile, the top of the pile is usually covered with a pile cap slightly larger than the pile body. On ships, this bollard is usually installed on the bow, stern, and left and right decks of the middle.

Modern ships, especially large ships such as container ships, oil tankers, bulk carriers, etc., can load and unload more than 10,000 tons of cargo within a few hours. As a result, the draught of the ship changes rapidly. Therefore, there are automatic mooring machinery and bollards, which can automatically retract and unwind the cables according to the changes in the cable tension to ensure the safety of the ship and the wharf.
