FAQ
What is the difference between single and double sheave pulleys?
A single sheave pulley has one wheel and changes the direction of the rope while providing a basic mechanical advantage. A double sheave pulley has two wheels on the same frame and can provide a greater mechanical advantage (typically 2:1 or 3:1 depending on the rigging configuration) by allowing multiple rope passes. Double sheave pulleys are used when heavier loads need to be lifted with less effort.
How do I select the correct pulley wheel diameter for my application?
The pulley diameter should be selected based on the rope diameter and the load requirements. As a general rule, the pulley diameter should be at least 10 to 20 times the rope diameter for optimal rope life. For light-duty applications like clotheslines, 2-3 inch pulleys are suitable. For heavier lifting applications, 4-6 inch pulleys provide better rope support and durability.
What rope types are compatible with this pulley?
The LD-061 is designed primarily for wire rope but is also compatible with natural fiber rope, synthetic rope (polypropylene, nylon, polyester), and steel cable. The groove size varies by wheel diameter, so ensure your rope diameter matches the pulley groove specification. Contact our sales team for specific rope compatibility recommendations.
What is the load capacity of these cast iron pulleys?
Load capacity varies by wheel diameter and sheave configuration. Generally, the 2-inch pulley handles up to 100kg, 3-inch up to 200kg, 4-inch up to 350kg, 5-inch up to 500kg, and 6-inch up to 700kg in single sheave configuration. Double sheave versions distribute the load across two wheels, increasing capacity. Always verify the specific load rating for your configuration and include an appropriate safety factor.
