ASME B30.30 sets periodic rope inspection intervals by rope service and hours of operation, with shorter limits for boom hoist rope. The Rope Compliance Program writes a procedure for every inspection the standard calls for and works out the removal criteria for the rope installed on each winch.
Every inspector knows what to check, where to measure, when it is due, and when a rope is done.
What you get
- Inspection procedures for every rope inspection in ASME B30.30, from frequent to periodic, written for each crane.
- A removal criteria checklist for every lifting winch, worked out for the rope installed: diameter reduction limit, broken wire limits from the B30.30 tables, and where to measure.
- Periodic inspection due dates for each rope, from its service and hours.
- Rope life strategies for every rope: lubrication, slip and cut, sheave groove checks and more.
- Two reviews a year of your periodic inspection reports, with written recommendations on what to change.
- Checklist updates whenever a rope is changed. Send the new rope certificate and reference diameter and we update the checklist.
A procedure for every ASME B30.30 rope inspection
| Inspection | When | Code | Clause |
|---|---|---|---|
| New rope | After break-in, record the reference diameter (existing ropes: at or before the next periodic inspection) | Shall | 30-1.5.1(i), 30-1.8.4(d) |
| Frequent (daily) | Running rope in service: all rope expected to be in use that day | Shall | 30-1.8.1(b) |
| Periodic, boom hoist rope | Normal service: 3 months or 500 h. Heavy: 2 months or 335 h. Severe: 1 month or 165 h. Special: under 165 h. Whichever comes first. | Shall | 30-1.8.1(c)(2) |
| Periodic, all other rope | Normal service: 12 months or 2,000 h. Heavy: 6 months or 1,000 h. Severe: 3 months or 500 h. Special: under 500 h. Whichever comes first. | Shall | 30-1.8.1(c)(2) |
| Unusual occurrence | After a lightning strike, abnormal shock load or overload | Shall | 30-1.8.1(d) |
| Idle 1 to 6 months | Frequent inspection before return to service | Shall | 30-1.8.3(a) |
| Idle over 6 months | Periodic inspection before return to service | Shall | 30-1.8.3(b) |
| Periodic report | Dated report of rope condition, with the measured diameter, kept on file | Shall | 30-1.8.4(b) |
Written to ASME B30.30-2023. Shall and Should show how the standard words each item. Our recommendations are kept separate from code requirements.
These intervals apply unless the equipment manufacturer, the rope manufacturer or a qualified person specifies otherwise (30-1.8.1(c)(2)).
Every winch checklist includes
- Rope spec and reference diameter
- Diameter reduction limit for the installed rope
- Broken wire limits for that construction
- Where to measure on that winch
- Sheave groove sizes: new 6% to 10% over nominal, worn not under nominal plus 2.5% (should, 30-1.7.2)
Rope life strategies for each rope
- Lubrication and cleaning
- Drum tension and spooling
- Sheave groove checks
- Slip and cut
- Rope length set so the drum takes tension away from a layer step-up
- New rope installation and break-in

How to start
- Book a free 15-minute call.
- Send the OEM manual, crane logbook and mill certs for the cranes you choose.
- Your checklists arrive within 10 business days.
Every winch used in lifting service is enrolled; reeving and pulling winches used only for rigging or assembly are covered only if you opt them in. The free crane renews at the standard rate. Record rope changes in the logbook and send us the new mill cert and reference diameter; checklists are only as current as the records supplied. Inspection and removal decisions remain with your competent person. Items marked as recommendations are CRS Practice, not code requirements.
