Manufactured in accordance with GOST 25573 - 82.
Safety factor relative to breaking load is not less than 5.
The split triangular link is used as the top end element of the sling. The lyre - shaped link has found wide application in the manufacture of multi - branch lines.
The split link design is more versatile in use in comparison with T - type links. Pt - type links are made of round steel by cold or hot bending. Link Pt3 is used for the manufacture of multi - branch slings of the "spider" type, it is smaller in comparison with Pt1, while maintaining the carrying capacity, as well as thickening in the upper corner.
Pt links are not recommended for use in slings of 1Sk and 3SK types (odd number of branches), since the load is unevenly distributed at the corners of the link.
