Parasailing uses a winch assembly driven by hydraulic motors and brakes. To generate the required RPM and torque of the winch system to create flight, designers use Ogura's MMC-28G-06 24 Volt DC clutch connected to their propulsion engine to drive a hydraulic pump to supply the needed hydraulic pressure and flow for hydraulic motors and brakes to spool or unspool the parasailing lifeline.

Extensive life and performance testing has been performed by our customers before placing them into service. Burnishing is always a good idea for these critical to safety applications. If any part of this system should fail, customers could end up in the drink, waiting to be rescued. Failure is not an option for this application.

That said, should the boats batteries fail, or clutch wiring become broken or torn while in use, and the clutch DC control becomes inoperative while in flight, there is a clever Ogura clutch 'limp home' feature which will allow for a full lock up of the clutch to continue full hydraulics operations and control without DC power. Designed for marine use, Ogura MMC clutch contains a full epoxy encapsulated coil, that when energized by a DC voltage, becomes and electromagnet. This electromagnet then attracts a multi pole armature plate across a small air gap. Once the armature crosses the airgap, it is then in contact with the multi pole rotor. This connects the input hub to the output bore, transmitting torque to the Hydraulics. When power is removed, a strong bidirectional spring works to open the airgap to disengage the clutch and shut down power to the hydraulics. With higher torques, and significantly better corrosion resistance, our customers are enjoying many safe seasons of full-time clutch use in this demanding and growing water sport.
