Overview
Calibrated and tested long-link round steel chains for mining monorail suspensions. Manufactured from alloy steel containing Ni, Cr and Mo; performance approximately 10% above the DIN 20637 reference.

Introduction
Designed as tested round steel chain suspensions for mining monorails. Long-link configuration adapted to suspension and material handling applications in mining environments.

Parameters (table)
Headers: Chain Size | d x p | d | p | b1 | Test Force | Breaking Force | Unit Elongation at test force (max.) | Unit Elongation at breaking force (min.) | Deflection F (min.) | Weight (kg/m).
Units: (mm) | (mm) | (mm) | (mm) | (kN) | (kN) | (%) | (%) | (mm) | (kg/m).
16x80: d x p = 16x80; d = 16 ±0.6 mm; p = 80 ±1.5 mm; b1 = 22.4 +3/-0 mm; Test Force = 60 kN; Breaking Force = 180 kN; Elongation at test force (max.) = 1.6%; Elongation at breaking force (min.) = 2.0%; Deflection F (min.) = 21 mm; Weight = 4.7 kg/m.
18x90: d x p = 18x90; d = 18 ±0.9 mm; p = 90 ±1.5 mm; b1 = 25.0 +3/-0 mm; Test Force = 100 kN; Breaking Force = 250 kN; Elongation at test force (max.) = 1.6%; Elongation at breaking force (min.) = 2.0%; Deflection F (min.) = 23 mm; Weight = 6.0 kg/m.

Materials and Performance
Manufactured from alloy steel with Nickel (Ni), Chromium (Cr) and Molybdenum (Mo). Chains are calibrated and factory-tested; typical performance exceeds the referenced DIN 20637 values by about 10%, providing increased safety margin for suspension applications.

Standards
Designed to meet DIN 20637 requirements.
