Leaf chain anchor blocks, also known as chain attachments or bolts, are essential components in lifting systems, ensuring a secure connection between Fleyer chains and lifting devices. Available in adjustable or fixed versions, our leaf chain anchor blocks comply with the ISO4347 standard. At Osra Special Parts, we offer highly reliable and durable tie rods with multiple customization options to meet the specific needs of every industrial application.
Adjustable: allow length adjustment for a secure connection adaptable to lifting requirements.
Fixed: designed for confined spaces
The electroforging process ensures high mechanical strength and durability while preserving the material’s fiber integrity. It also reduces machining waste typical of bar production, providing economic advantages. Contact us to check if your adjustable chain tie rods can be produced with this technology.
When electroforging is not feasible, we produce adjustable leaf chain anchor blocks from solid round bars, guaranteeing reliability and precision. This technology is also used for fixed leaf chain anchor rods, offering solutions suitable for all needs.
A surface treatment that provides metals with a dark finish resistant to corrosion and wear. This chemical or protective process creates a uniform black-blue coating, improving aesthetics and durability. Widely used in automotive, furniture, and manufacturing sectors for its resistance to weathering and abrasion.
Galvanic or electrolytic zinc plating offers corrosion resistance, protection, cleanliness, and shine. Applied by hot-dip immersion or electrodeposition, it is extensively used in construction, automotive, and shipbuilding to preserve the integrity and appearance of metal components exposed to atmospheric agents and wear.
A non-electrolytic anticorrosive treatment based on a patented aqueous solution that provides excellent weather resistance, long-lasting protection, and reliable performance even in aggressive environments.
A chemical treatment applying zinc or manganese phosphates to metals, forming a protective layer that enhances resistance to corrosion and prepares surfaces for further coatings like paint or zinc plating. It ensures durability and optimal performance
