Premium open type pulleys designed for industrial lifting and rigging applications. Heavy duty open pulley blocks for wire rope, cable handling & material transmission with customizable sizes and high load capacity. OEM open pulley supplier from China.
The Rongda Metal Open Type Pulley is a robust industrial component designed to facilitate wire rope lifting, cable guiding, tensioning and material handling in heavy-duty applications. Featuring an open sheave design that allows easy installation and wire rope alignment, this pulley block is ideal for rigging, lifting equipment, construction machinery and power transmission systems.
Open type pulleys are essential in mechanical systems where flexible rope or cable routing and high load capacity are required. They ensure smooth rope movement, reduced friction and optimized mechanical performance — critical for industrial efficiency and safety.
Our open type pulleys are engineered from premium cast steel or carbon steel with precision machining to ensure exceptional durability, high tensile strength and long service life. The open design makes it simple to install and maintain the pulley sheave, especially in confined spaces where closed pulleys may be difficult to fit.
These pulley blocks are widely used in lifting, hoisting, tensioning systems, wire rope guides and conveyor setups, offering stable operation under heavy loads and harsh industrial environments.
Key Industrial Applications:
Wire rope lifting and guiding
Construction rigging and material hoist systems
Cable tensioning solutions
Conveyor belt and transmission systems
Marine and offshore lifting gear
Designed for easy rope access and installation, the open type pulley allows fast threading of wire rope or cable, reducing assembly time and operational downtime. Suitable for both temporary rigging and permanent installations.
Manufactured with rugged materials and precision casting processes to handle high tensile loads and resist wear, deformation, and fatigue in industrial lifting applications.
High-quality bearings and accurate groove profiling ensure smooth sheave rotation, minimizing rope wear and system friction for extended service life.
Available in various diameters, load ratings and configuration options. OEM customization supported for specific industrial requirements and special usage conditions.
Open construction allows quick inspection, lubrication and replacement of worn components without dismantling the entire assembly.
