When CLARK’s S-Series will automatically engage an internal parking brake any time the forklift operator has left the seat or the engine loses power. No cables, no annoying alarms, the forklift does it for you. When the operator returns to the forklift, applies the foot brake and engages the engine, the parking brake is automatically released. Just one of the many features that makes CLARK’s S-Series, Smarter, Stronger and Safer.
