ASTM F1106-87(2018)

Standard Specification for Warping Heads, Rope Handling (Gypsy Head, Capstan Head)

ABSTRACT
This specification covers warping heads used with windlass, winch, and capstan drive units to pull rope on board ships. Warping heads are primarily for use with fiber rope, natural, or synthetic. Warping heads with external ribs or whelps on the barrel, notched flanges, attached storage drums, unfinished drums, or non heat-treated fabrications, are considered special. The size of the warping head shall be identified by the nominal barrel diameter measured at the smallest point of the barrel. These warping heads are furnished in two types: Type I is with a cylindrical barrel which is generally used in but not restricted to horizontal shaft applications and Type II is with a conical barrel which is mounted with the large end of the barrel toward the drive machinery. It is generally used in but not restricted to vertical shaft applications. On the other hand, the warping heads are divided into four grades according to composition: Grade 1 is fabricated from any combination of structural steel plate, pipe, tubing, or steel castings and joined by electric welding; Grade 2 is made from mild to medium strength steel; Grade 3 is fabricated from any combination of steel plate or steel castings and joined by electric welding; and Grade 4 is cast from high strength steel castings. Principal dimensions, tolerances, and strength requirements are discussed.
SCOPE
1.1 This specification covers warping heads used with windlass, winch, and capstan drive units to pull rope on board ships. Warping heads are primarily for use with fiber rope, natural, or synthetic.  
1.2 Warping heads with external ribs or whelps on the barrel, notched flanges, attached storage drums, unfinished drums, or non heat-treated fabrications, are considered special and are permitted within the scope of this specification when fully described under special ordering information.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The size of the warping head shall be identified by the nominal barrel diameter measured at the smallest point of the barrel.
4.2 Warping heads under this specification are furnished in two types as follows:
4.2.1 Type I Warping Head With Cylindrical Barrel—Generally used in but not restricted to horizontal shaft applications. Also
known as a gypsy head (see Fig. 1).
4.2.2 Type II Warping Head With a Conical Barrel—Mounted with the large end of the barrel toward the drive machinery.
Generally used in but not restricted to vertical shaft applications. Also known as a capstan head (see Fig. 2).
4.3 Warping heads are divided into four grades as follows:
4.3.1 Grade 1—Fabricated from any combination of structural steel plate, pipe, tubing, or steel castings and joined by electric
welding.
4.3.2 Grade 2—Cast from mild to medium strength steel.
4.3.3 Grade 3—Fabricated from any combination of steel plate or steel castings and joined by electric welding. Heat treated to
provide a surface hardness ( ⁄8 in. (3 mm) deep) of 200 to 250 Brinell on rope contact surface. Rope contact surface finished to
an average 125-125 to 160-μin. (3175-(3175 to 4064-μmm) finish.
