Cable replacement is a service operation โ the block must be returned to an authorised service centre for fitting and re-certification. Field replacement is not approved.
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.
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.
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.
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.
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.
20 m for the CMHCR30020 block. 25 m for the CMHCR30025 block. Confirm your block model before ordering.
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.
No. The cables are matched to the specific block model and drum diameter. Use only the correct length for your block.
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.
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.
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.
