Product Overview
The G80 / G100 Alloy Steel Lifting Chain (widely recognized across heavy industries as the High Tensile Hoist Load Chain, and designated across Spanish-speaking industrial markets as Cadena de elevacion de acero aleado G80 / G100) is a high-strength, precision-engineered load chain designed for demanding hoisting, rigging, and load-handling applications. Engineered for integration with manual chain blocks, electric chain hoists, lever hoists, overhead cranes, and assembled chain slings, this chain provides optimal load transmission and wear resistance.
Manufactured from high-grade alloy steel, this lifting chain delivers structural integrity, impact resistance, and durability under severe dynamic loading. Available with versatile surface treatments—including barreling, polishing, blackening, hot-dip galvanizing, and electric galvanizing—it performs reliably in factories, construction sites, ports, shipyards, and outdoor marine environments.
Advanced Mechanical Engineering & Manufacturing Highlights
High-tensile lifting chains require precise heat treatment, strict dimensional tolerance control, and protective surface finishes:
Premium Alloy Steel Construction: Produced from high-quality alloy steel to deliver high tensile strength, toughness, and deformation resistance during heavy-duty lifting.
G80 & G100 Performance Grades:
Grade 80 (G80): Standard industrial hoisting grade providing robust load-bearing capabilities for general overhead lifting and sling assemblies.
Grade 100 (G100): Advanced high-strength grade offering enhanced load capacities for extreme lifting requirements without increasing chain dimensions.
Minimum 4:1 Design Safety Factor: Built with a minimum 4:1 safety factor relative to ultimate breaking strength, ensuring safe, reliable operation under dynamic shock loads.
Comprehensive Surface Protection Options:
Barreling / Self-Color: Cost-effective finish for standard indoor applications.
Polished Finish: Smooth surface finish ideal for precision manual and electric hoists.
Blackened Finish: Thermally treated black oxide surface for mild corrosion resistance and sleek aesthetic.
Galvanized (Hot-Dip & Electric): Superior corrosion protection against moisture, rust, and chemical exposure in marine, port, and outdoor environments.
Global Standard Compliance: Manufactured in full accordance with international specifications including ISO, DIN, BS, JIS, and ASTM, ensuring full compatibility with global crane fittings and hoist sprockets.

B2B Procurement Note: The pitch-to-diameter ratio (3:1, e.g., 6*18 mm, 8*24 mm, 10*30 mm) ensures smooth engagement with pocket wheel sprockets in manual chain blocks and electric chain hoists.
Critical Working Load Management & Safety Engineering
Rigging managers integrating the en818-2 alloy steel sling chain must observe working capacity rules:
Surface Finish Capacity Factors: Galvanized chain variants offer enhanced surface hardness and corrosion barrier protection, supporting elevated Working Load Limits across corresponding diameter sizes.
System Component Matching: Always match chain diameter and pitch precisely to host equipment sprockets (e.g., manual blocks, electric hoists, or rigging master links) to prevent binding, premature pocket wear, or chain derailment under load.
Industrial Applications
Manual & Electric Hoist Assemblies: Primary internal load chain for manual chain blocks, lever hoists, and electric chain hoists.
Multi-Leg Rigging Slings: Assembled into 1-leg, 2-leg, 3-leg, and 4-leg chain sling setups fitted with clevis hooks, grab hooks, and master links.
Overhead & Gantry Crane Systems: Deployed as heavy hoist lines for overhead travelling cranes and portable gantry crane systems.
Port, Marine & Offshore Logistics: Utilized in galvanised finishes for heavy cargo handling, marine equipment maintenance, and shipyard rigging.
Construction & Structural Erection: Deployed on job sites for heavy structural steel positioning, concrete panel hoisting, and machinery placement.
