Mine Hoist Wire Rope: A Practical Guide to Winding, Balance and Guide Rope Selection
Mine hoist wire rope explained: drum vs friction (Koepe) winder rope selection, triangular strand and locked coil constructions, static safety factors by jurisdiction, balance and guide ropes, capping and dead coils, and AS 4812 winding-rope discard criteria. By Andri, Technical Writer & Crane Rope Specialist, Aulone.
Wire Rope Proof Load Testing: What a Proof Test Proves and What It Doesn’t
Wire rope proof load testing explained: what a proof test actually verifies, where the 2x WLL rule comes from, why the rope itself is break tested instead, proof force by product and standard, how to read a proof test certificate and why a proof test is not an in-service inspection. By Andri, Technical Writer & Crane Rope Specialist, Aulone.
Wire Rope Lubrication: How to Choose a Lubricant, Apply It and Set an Interval That Works
Wire rope lubrication explained: penetrating vs coating lubricants, ISO 4346 lubricant requirements, five application methods compared, lubrication intervals by application, cleaning before lubrication and the field tests that tell you a rope is protected. By Andri, Technical Writer & Crane Rope Specialist, Aulone.
What Should I Look for When Choosing Rotary Drilling Rig Wire Rope?
Rotary drilling rigs work under heavy loads and tough ground conditions. A poor wire rope can cause unexpected downtime, higher maintenance costs, and serious safety risks. I believe choosing the right rope is just as important as choosing the right drilling equipment.
Wire Rope Elongation: Constructional vs Elastic Stretch and How to Plan for Both
Wire rope elongation explained: constructional vs elastic stretch, typical stretch values by construction, the elastic stretch formula with a worked example, pre-stretching, re-tensioning and warning signs. By Andri, Technical Writer & Crane Rope Specialist, Aulone.
Lang’s Lay vs Regular Lay Wire Rope: What Lay Direction Means and Which One to Order
Lang’s lay vs regular lay wire rope explained: EN 12385-2 lay codes (sZ, zZ, zS, sS), the rotation rule, fatigue and abrasion trade-offs, lay length, and how to order the right lay. By Andri, Technical Writer & Crane Rope Specialist, Aulone.
Gantry Crane Wire Rope: A Practical Guide to RTG and RMG Hoist Rope Selection and Care
How to choose wire rope for RTG and RMG gantry cranes: the right construction and core, 1960 galvanized grade, 5:1 design factor sizing with a worked example, multi-layer drum rules, ISO 4309 discard criteria and salt-air maintenance. By Andri, Technical Writer & Crane Rope Specialist, Aulone.
Wire Rope Sling Inspection: ASME B30.9 Removal Criteria, Tags and a Field Checklist
How to inspect a wire rope sling per ASME B30.9: the three inspection levels, tag requirements, the full removal-from-service criteria table, broken wire limits, hitch capacity multipliers and a field checklist. By Andri, Technical Writer & Crane Rope Specialist, Aulone.
Wire Rope Socket Guide: Wedge Socket vs Spelter Socket and How to Choose
A wire rope is only as strong as its end termination. A spelter or swaged socket keeps 100% of the rope’s minimum breaking force; a wedge socket keeps about 80% but can be made and adjusted in the field in minutes. A crane rope specialist’s complete guide to wire rope sockets: types, termination efficiency, zinc vs resin pouring, wedge socket installation rules and inspection. By Andri, Aulone.
Wire Rope Storage and Handling: How to Protect Rope Before It Ever Takes a Load
Most wire rope is damaged before its first lift, not during it: wet ground, stacked drums, dropped reels and careless unreeling create kinks, birdcages and corrosion that no inspection can undo. A crane rope specialist’s complete guide to storing, handling, unreeling and maintaining wire rope from delivery to installation. By Andri, Aulone.
Wire Rope Failure Case Studies: 6 Real-World Failures and the Lessons Behind Each One
Six documented wire rope failures — a dropped nacelle, an offshore crane fast line, a drilling winch rope, two steel-mill ladle cranes and a workshop hoist — analyzed by a crane rope specialist: the root causes, the warning signs everyone missed, and the exact practices that prevent each failure. By Andri, Aulone.
Wire Rope Sheaves and Drums: Groove Geometry, D/d Ratio and Fleet Angle Explained
Wire rope sheave and drum guide: groove radius tolerances, minimum D/d ratios by rope construction, the 1.5-degree fleet angle rule with a worked example, drum groove pitch and multi-layer spooling, and the wear criteria that tell you when to re-groove or replace. By Andri, Aulone.
