Doughty Single Sheave Pulley

Doughty Single Sheave Pulley

The Doughty Single Sheave Pulley is a high-performance rigging solution designed specifically for use in theatre, film, and TV production environments. Built with a modular construction, this pulley system allows for easy assembly using a standard range of components, making it versatile and adaptable to a wide variety of specialist applications.

This single sheave pulley is compatible with both fiber and wire ropes and supports a safe working load of 150 kg (331 lbs). With three available sheave sizes—4'', 6'', and 7'' diameters—users can select the correct configuration based on their specific rigging requirements. The basic pulley is designed to accept a full range of fixings and brackets, enhancing its functionality in complex lifting or directional systems.

Understanding the terminology is key: the term "sheave" refers to the grooved rotating wheel within the overall pulley system. In contrast, the "pulley" represents the complete system used to change the direction of mechanical force via rope or wire. This distinction is important for ensuring compatibility and safe usage in professional settings.
