What the Technical Experts Say

The Harken CMC CLUTCH has allowed our team to replace three devices with one by its ability to lower and raise heavy loads along with its comparatively smaller size. It has reduced our financial expenditures in equipment and training time. CLUTCH’s ability to be used in both Rope Access and Rescue has simplified and streamlined our training and operational programs. – Mark Pfeifer, President & CEO, Ronin Safety & Rescue.

“Harken Industrial has contributed its core competency - creating high performance load-handling equipment with the development of the CLUTCH. Combine that with CMC’s expertise in designing products specifically for the Rescue and Rope Access industries and you’ve got a winning combination for CLUTCH users. We know that the device has the capacity to lessen the margin of error during operations, as well as provide more safety and efficiency.” – Sean Cogan, Technical Sales Manager, Harken Industrial.
