High-Strength Drop Forged Chains for Heavy Industry

Overview

The High-Strength Drop Forged Chains are built for extreme-duty applications requiring unmatched durability and impact resistance. Manufactured using a proprietary drop-forging process, these chains feature solid one-piece links that eliminate weak points, making them ideal for heavy lifting, mining, and construction equipment.

Features

Drop-Forged Construction: Single-piece alloy steel links (4140/4340) offer 30% higher impact strength than pressed-link chains, with tensile ratings up to 500kN.

Dual/Triple Link Configuration: Modular design allows easy adjustment of chain length and load capacity for custom machinery setups.

Anti-Rust Protection: Hot-dip galvanized coating (85μm thickness) provides Class C5-M corrosion protection for offshore and marine applications.

High Clearance Design: Oversized bushing bores reduce friction during articulation, enabling smooth operation under sudden load changes.

API Compliant: Meets API 7F-22 standards for drilling and oilfield equipment, ensuring reliability in high-pressure environments.

Application

Oil & Gas Industry: Used in drilling rig hoists, derrick chains, and pipeline tensioning systems.

Mining Excavators: Powers bucket elevators, dragline chains, and ore cart drives in underground and open-pit mines.

Cranes & Hoists: Critical for overhead cranes, port machinery, and heavy-duty lifting equipment requiring fail-safe performance.

Steel Mills: Supports billet conveyors, blooming mill drives, and ladle handling systems in high-temperature, high-dust environments.
