Video Explores Custom Clutch for Salmon Barrier System

To prevent salmon from swimming into flood drains in the Sacramento River, local agencies built a special hoist system that raises and lowers grated barriers. Part of the assembly is a custom torque limiter that slips the system whenever debris buildup creates an excess of force on equipment. These torque limiters feature a special housing that supports over 250 pounds and can withstand the outdoors 24/7. They also make it easy to adjust the slip torque setting on-site. Thanks to our torque limiters, the hoist system automatically lowers the gates upon overload, protecting the equipment. To learn more, please visit
