CLUTCH By Harken Industrial
SHIPPING IN DECEMBER!
Introducing the all-new CLUTCH, the latest evolution in rescue and rope access hardware that enables the technical rope professional to do more with less. This multi-purpose device was designed and engineered in collaboration by two companies with a collective 90 year history in rope management under heavy loads: CMC, a company with roots in rescue and rope access, and Harken Industrial, a manufacturing company with roots in high performance sailing.
Designed for intuitive, efficient operation, ease of use and optimal control, the versatile CLUTCH is suited to a multitude of rigging operations.
PPE Inspections
- The CLUTCH should have a periodic inspection performed by a competent person at least once every 12 months, after any exceptional event(s), or if there is any doubt to the condition of the product. For each inspection, CMC recommends the Periodic PPE Inspection Form be completed, signed and archived for the life of the product. In case of retirement, ensure to render the device useless before disposal to prevent further use.
The CLUTCH User Manual, CLUTCH Inspection Procedure and CLUTCH Periodic PPE Inspection Form provided below are resources for detailed inspections. They are not exhaustive and inspection by a competent person is required. See the PPE homepage for more information on a “competent person.”
By performing a periodic inspection and signing periodic inspection forms, you are declaring yourself as a competent person and assuming responsibility for the implementation of the inspection processes and proper disposition of the PPE.
Specs
- Single wearable tool suited for efficient hauling, controlled lowering, smooth personal descent, easy ascending and belaying.
- Stainless steel ratcheting and rotating sheave provides efficient and audible progress capture.
- Rope loading/unloading is secured with an innovative double-latched side plate design that is independent of the device‘s attachment point.
- Anti-Panic brake and force limiting features ensure operational safety and overload protection.
- Machined aluminum chassis clad with stainless steel wear guards ensures lightweight durability.
- Integrated becket allows for direct connection of mechanical advantage systems.
- The only 10.5-11.5 mm rope diameter compatible device certified to NFPA 1983 (G-Rated), ANSI Z359.4 and EN 12841/C, 341/2A, and 15151/8.
- The CLUTCH and CMC’s G11 Lifeline can be used together to build NFPA G rated systems using 11 mm rope, saving space and reducing weight.
- Patent pending.
BECKET 22 KN (4496 LBF)
Placing a CLUTCH at the head of a mechanical advantage system enables efficient hauling via the integrated rotating sheave (NFPA G-rated Pulley) while allowing immediate lowering of the load without system modification.
Warnings:
- Fully read and understand the CLUTCH technical manual before applying the following techniques.
- Mastering these techniques requires training.
- Consult a professional before attempting to perform these techniques on your own.
Test Method
A 100kg test mass was raised with several rigging configurations placing different devices at the head of the system:
The test rope was CMC G-11 Lifeline.
For the 3:1 system, a CMC PMP Swivel Pulley was utilized.
The force required to raise the test mass at a constant speed was recorded. Due to variables that are difficult to reproduce, the data is given for information only.
Efficiency (EFF) is calculated by dividing the theoretical force required to raise the load by the measured force required.
