Abstract
A system for preventing an engine included in a work machine from restarting, after the work machine is tipped over. A sensor included in the work machine is configured to detect a tipping incident. If a tipping incident is detected, the sensor sends out a signal configured to shut down the engine and a tilt signal configured to prevent the engine from restarting. The engine is only restarted if certain steps are undertaken by an operator and a reset switch is activated.
Claims20
A work machine having an ordinary operating condition, the work machine comprising:
- a chassis;
- an engine supported on the chassis;
- and
- a sensor supported on the chassis and configured to measure an amount of deviation of a current operating condition of the work machine from the ordinary operating condition of the work machine;
- in which the sensor is configured to direct the engine to shut down if the amount of deviation measured by the sensor exceeds a predetermined threshold value;
- and
- in which the engine is prevented from restarting if the amount of deviation measured by the sensor exceeds a predetermined threshold value.
A work machine having an ordinary operating condition, the work machine comprising:
- a chassis;
- an engine supported on the chassis;
- a starter in communication with the engine;
- a sensor supported on the chassis and configured to measure an amount of deviation of a current operating condition of the work machine from the ordinary operating condition of the work machine;
- and
- a circuit interrupter in communication with the sensor and the starter;
- in which the sensor is configured to direct the engine to shut down if the amount of deviation measured by the sensor exceeds a predetermined threshold value;
- and
- in which the circuit interrupter is configured to prevent the starter from restarting the engine if the amount of deviation measured by the sensor exceeds the predetermined threshold value.
