Horizontal Lead Blocks
Tork Winch directional blocks are manufactured from C1045 medium carbon steel. Sheaves are zinc plated for sacrificial corrosion protection, and block housings are powder coated for enhanced corrosion resistance and surface durability. Sheave pitch diameters maintain a minimum 15:1 D:d ratio relative to wire rope diameter. Blocks are rated to their full Working Load Limit at a 180° rope wrap angle. Vertical units incorporate flanged oil-embedded bronze bushings as standard, with sealed or roller bearings available as alternatives.
