Chain Pulley Block
Jayco Chain Pulley Block – Hook Suspension Type is a heavy-duty, manually operated lifting device designed for safe, efficient, and reliable lifting, lowering, and positioning of heavy loads in industrial, commercial, and maintenance applications. Manufactured using premium-quality materials, precision-machined components, and advanced manufacturing processes, our chain pulley blocks ensure smooth operation, high mechanical efficiency, excellent durability, and long service life.
Jayco Chain Pulley Blocks are available in Mild Steel (MS) and Stainless Steel 304 (SS304) construction to suit different industrial environments.
The Mild Steel (MS) model is suitable for general engineering industries, fabrication shops, warehouses, workshops, power plants, construction sites, and material handling applications.
The Stainless Steel 304 (SS304) model is specially designed for hygienic and corrosive environments such as food processing, pharmaceutical, dairy, beverage, chemical, marine, and clean-room industries where rust resistance and cleanliness are essential.
The Hook Suspension design allows quick installation by simply hanging the block from an overhead beam, eye bolt, lifting hook, monorail beam, jib crane, gantry crane, or EOT crane without requiring permanent mounting.
Jayco Chain Pulley Blocks are manufactured in accordance with IS 3832 and are factory tested to ensure maximum safety, reliability, and performance.
