Torque Blocker – Hydraulically Actuated Overload Clutch

Torque Blocker Hydraulically Actuated Overload Clutch

Protect your critical heavy-duty equipment with the Riverhawk Torque Blocker. The Torque Blocker is a hydraulically actuated overload clutch designed to mount between two machine shafts. When set, it forms a ridged connection between the two shafts. Upon a torque overload, the unit releases to allow the two shafts to rotate freely for coast down. The Torque Blocker fits within the coupling spacer that connects the shafts of the drive and driven equipment. It provides over torque protection by releasing when a preset torque load is exceeded.

Examples of overload are short circuit conditions in electric generators, running restart of electric motors, jams in rolling mills and liquid slugs in compressors. After release, the Torque Blocker then allows machinery to safety coast down utilizing the bearings within the unit. Reset is simple and quick.
