Torque_Blocker - Riverhawk

Torque Blocker

Protects rotating equipment from torque overload by attaching to a shaft(or coupling) by releasing when a preset load is exceeded, allowing for safe machinery coast down.

Protect your critical heavy duty equipment with the Riverhawk Torque Blocker. The Torque Blocker fits within the coupling spacer that connects the shafts of drive and driven equipment. It protects equipment from torque overload 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 safely coast down. Reset is simple and quick. Operators pump up the hydraulic clamp, reset the pins, drain the oil and reset is complete.
