Product Overview
This triple-sheave power line pulley block features a lifting-eye attachment and is available with working load limits from 3.2 to 50 metric tons. Its multi-sheave arrangement is designed for wire-rope guidance during tower erection, line stringing and equipment lifting.
Product Features
- Precision-cast steel sheaves provide greater strength and durability than conventional cast-iron sheaves.
- The hinge components are forged from high-quality low-carbon alloy steel and heat-treated for improved overall strength and service life.
- Heat-treated alloy-steel attachment components provide a compact, lightweight and fatigue-resistant structure.
- The triple-sheave arrangement provides stable wire-rope guidance for higher-capacity lifting and pulling operations.
Applications
Suitable for utility tower erection, overhead conductor stringing, equipment installation and other lifting operations.
