The Yale Cable Block Replacement Rope is the authorised replacement cable for the Yale CMHCR30020 and CMHCR30025 cable block models, available in matched 20 m and 25 m lengths. Replacement of the cable is a service operation that must be carried out by Columbus McKinnon or an authorised service centre — the block cannot be safely re-cabled in the field. Manufactured by Columbus McKinnon, supplied with a test certificate.

CMCO Group | EN ISO 9001 Certified | Authorised Service Part
This is an authorised service part manufactured by Columbus McKinnon under the Yale lifting brand. Supplied for cable replacement of compatible Yale CMHCR300 series blocks during competent person service. The block in service must be re-certified by a competent person after cable replacement before being returned to use.
Suitable Applications
Replacement service part for Yale CMHCR30020 and CMHCR30025 cable blocks. Fitted by Columbus McKinnon or an authorised service centre during planned service or after cable damage.
How to Use the Replacement Rope
- Order the correct length for your block — 20 m for the CMHCR30020, 25 m for the CMHCR30025.
- Return the block to Columbus McKinnon or an authorised service centre for cable replacement.
- After re-cabling, the block must be re-certified by a competent person before being returned to use.
- Field replacement of the cable is not approved — the brake mechanism and internal components must be inspected during cable replacement.
Warning:
Do not attempt to replace the cable in the field. The block brake mechanism, internal drum, and cable tension settings must be checked during cable replacement, and this requires authorised service centre equipment and competent person re-certification.
Safety Information
- Field replacement of the cable is not approved.
- The block must be re-certified after any cable replacement before being returned to use.
- Use only the matched replacement cable length for your block model.
- Do not use the block with a damaged or worn cable — withdraw from service immediately.
Inspection and Maintenance
This is a replacement part with no maintenance requirement until fitted to a block. Once fitted, follow the block's standard maintenance and inspection schedule.

Frequently Asked Questions
Q: Can I fit the replacement cable myself?
No. Field replacement of the cable is not approved. The block must be returned to Columbus McKinnon or an authorised service centre for re-cabling, internal inspection, and re-certification.
Q: Which length do I need?
20 m for the CMHCR30020 block. 25 m for the CMHCR30025 block. Confirm your block model before ordering.
Q: How often should the cable be replaced?
Replace if any visible damage is found during inspection, or as part of planned service. Cable replacement is typically considered during the manufacturer-recommended internal service interval, typically every 2 years.
Q: Is the cable interchangeable between the 20 m and 25 m blocks?
No. The cables are matched to the specific block model and drum diameter. Use only the correct length for your block.
Q: Does the cable come with the connectors?
The replacement rope is supplied with end-terminations as required for fitting to the block. The end-connectors (swivel hook, anchor hook) are typically retained from the original block during service.
Q: Why can't the cable be replaced in the field?
The block brake mechanism is calibrated to the cable specification and drum tension. Replacement requires the block to be partially disassembled and the brake re-set, which requires authorised service centre equipment.
Q: How quickly is the cable replacement service?
Typical turnaround is 5 to 10 working days from receipt at an authorised service centre. Contact us to arrange collection of your block for service.
