Abstract
A system for preventing the overturning of the bin of a tipper truck during the raising of the bin for purposes of unloading includes a lateral level sensor to sense the lateral orientation of the tipper truck, and a longitudinal level sensor for sensing the longitudinal inclination of the bin. A processor processes the outputs of the lateral and longitudinal level sensors to derive a measure of risk of overturning. The system also includes a display for displaying an indication responsive to the measure of risk. The processor preferably processes the output of the lateral level sensor to calculate a rate of change of lateral inclination of the tipper truck. Optionally, a mechanism may be provided for interrupting the raising of the bin, the mechanism being responsive to the processor.
Claims16
A system for preventing the overturning of a tipper truck during the raising of a bin for purposes of unloading, the system comprising:
- (a) a lateral level sensor associated with the tipper truck generating an output indicative of the lateral orientation of the tipper truck;
- (b) a longitudinal level sensor associated with the bin of the tipper truck generating an output indicative of the longitudinal inclination of the bin;
- (c) a processor for processing said outputs of said lateral and longitudinal level sensors to derive a measure of risk of overturning based on said inputs from both said lateral and longitudinal level sensors;
- and
- (d) means for displaying an indication responsive to said measure of risk.
A method for preventing the overturning of a tipper truck during the raising of a bin for purposes of unloading, the method comprising the steps of:
- (a) generating a first output indicative of the lateral inclination of the tipper truck;
- (b) generating a second output indicative of the longitudinal inclination of the bin;
- and
- (c) processing both said first and second outputs to determine a measure of risk of overturning of the tipper truck, said processing including:
- (i) processing said first output to determine a maximum safe longitudinal inclination of the bin as a function of the lateral inclination of the tipper truck;
- and
- (ii) comparing said second output with said maximum safe longitudinal inclination.
