🔬 MAGNOGRAPH II NON-DESTRUCTIVE TESTING
SIEMAG TECBERG provides professional NDT services using advanced Magnograph II equipment to detect internal rope defects invisible to visual inspection. Our certified technicians deliver comprehensive reports meeting MSHA standards and CFR 30 Part 56.19024 requirements.
🔍 Advanced NDT Testing with Magnograph II
II NDT
LMA • LF • TMA
Loss of Metallic Area (LMA)
Detects corrosion, wear, and general deterioration throughout rope cross-section
Local Faults (LF)
Identifies broken wires, wire clusters, and localized damage within rope structure
Total Metallic Area (TMA)
Measures actual rope strength and provides quantitative analysis of rope condition
MSHA REQUIREMENT ALERT
MSHA recommends that mine operators use NDT when conducting required six month inspections of wire ropes. NDT equipment utilizes magnetic or ultrasound waves to view the inner workings of the rope without cutting into it, much like a CT scan or MRI. Our Magnograph II service ensures full MSHA compliance.
Visual Inspection Points
1Wire Breaks & "Porcupining"
Look for: Individual wire breaks, protruding wires, or "bird caging" where outer strands separate from the core. Use the "rag-and-visual" method - broken wires will often "porcupine" (stick out) and snag on cotton cloth.
CFR 30 Part 56.19024: The number of broken wires within a rope lay length, excluding filler wires, exceeds either five percent of the total number of wires or fifteen percent of the total number of wires within any strand.
2Corrosion & Rust Formation
Look for: Red rust, pitting, or discoloration on wire surfaces. Insert a marlin spike beneath two strands and rotate to lift strands and open rope to check internal corrosion.
CFR 30 Part 56.19024: If a rope shows corrosion it fails - we always consider wear and/or corrosion together for rope deterioration assessment.
3Abrasive Wear & Diameter Reduction
Look for: Wear of 1/3 of the original diameter of the individual outside wires. Measure diameter at multiple points using calipers. Surface wear like pining and crushing.
CFR 30 Part 56.19024: Diameter reduction due to wear that exceeds six percent of the baseline diameter measurement.
4Kinking & Crushing Damage
Look for: Kinking, crushing, cutting, unstranding, bird caging or other physical damage that has distorted the shape of the wire rope.
Critical Action: Significant distortion of the wire rope structure such as kinking, crushing, unstranding, birdcaging requires immediate removal.
5Bird Caging & Core Protrusion
Look for: Outer strands ballooning out from the rope body, core slippage, or core protrusion. Signs of core failure or steel core protrusion between the outer strands.
Critical Action: Replace immediately when bird caging is observed - indicates structural failure.
6End Connections & Hardware
MSHA Requirement: Daily examination of rope fastenings for defects. Check for improperly applied end connections, significantly corroded, cracked, bent, or worn end connections.
Action Required: Replace damaged hardware immediately; ensure proper torque on connections per SIEMAG specifications.
MSHA Inspection Frequency Requirements
| Mine Operation Type | Visual Inspection | NDT Testing | MSHA Regulation |
|---|---|---|---|
| Personnel Transport | Daily when in use | 6 months | 75.1400(d) - Daily examination required |
| Material Hoisting | Before each shift | 6 months | 75.1400-3(b) - Comprehensive examination |
| Production Hoisting | Daily during operation | 6 months | MSHA Safety Alert guidelines |
| Emergency Systems | When activated | 6 months | Standby equipment protocols |
🚨 IMMEDIATE REPLACEMENT CRITERIA - CFR 30 Part 56.19024
Unless damage or deterioration is removed by cutoff, wire ropes shall be removed from service when any of the following conditions occurs:
- The number of broken wires within a rope lay length, excluding filler wires, exceeds either five percent of the total number of wires or fifteen percent of the total number of wires within any strand
- On a regular lay rope, more than one broken wire in the valley between strands in one lay length
- A loss of more than one-third of the original diameter of the outer wires
- Rope deterioration from corrosion
- Distortion of the rope structure
- Heat damage from any source
- Diameter reduction due to wear that exceeds six percent of the baseline diameter measurement
- Loss of more than ten percent of rope strength as determined by non-destructive testing
