Engine Stranglers

Liquip offers a range of mechanical engine stranglers that can shut down the engine of fuel delivery trucks in an emergency situation such as roll over.

The engine strangler can be pneumatically or manually actuated to stop the engine in case of diesel runaway, and is easily re-set for continued use once activated.

The engine strangler can also be actuated by the rollover sensor via a solenoid valve. This provides a complete system of engine protection and electrical isolation for maximum vehicle safety.
