Turnbuckle for rigging
Published on April 30, 1999
China State Shipbuilding Corporation
Implemented on August 1, 1999
CB/T3818—1999
This standard is a revision and merger of GB561-65 "Types and sizes of turnbuckles for open rigging for ships", GB562-65 "Types and sizes of turnbuckles for closed rigging for ships", GB563-65 "Types and sizes of turnbuckles for rotating rigging for ships" and GB564-65 "Technical conditions for turnbuckles for ship rigging".
The original standard is too old and the strength level is not matched, which cannot meet the selection requirements of various types of ships. This revision expands the scope of application and the selection of materials, establishes 11 types and 19 specifications, and gives the safe working load of the strength level of the turnbuckle to meet the matching of various ships.
From the date of implementation, this standard will replace GB561-65, GB562-65, GB563-65, and GB564-65. This standard is proposed by the National Technical Committee for Ship Equipment Standardization. This standard is under the jurisdiction of Jiangnan Shipyard (Group) Co., Ltd. The drafting unit of this standard: China Shipbuilding. The main drafters of this standard: Li Fuchang and Song Ren.
