ISO 13795 Type A Welded Steel Bollards With Compact Base Plate Ship Towing Equipment
Description:
ISO 13795 type A welded steel bollards with compact base plate ship towing equipment is a double bitt type bollard. It is used for both mooring & towing. The nominal sizes are: 150, 200, 250A, 250B, 300A, 300B, 350A, 350B, 400A, 400B, 450A, 450B, 500A, 500B, 550A, 550B and 600. Base plates is weldable steel plates having a yield point of not less than 235 N/mm 2 ; posts material is weldable steel plates having a yield point of not less than 235 N/mm 2 or equivalent steel tubes. The posts of the bollards is constructed from steel pipes or formed from plate. Fins is installed to keep the ropes as low as possible so as to reduce the loads to the bollard posts from the mooring/towing ropes. An eye plate for tying the stopping-off rope or chain is provided.
