Abstract
The present disclosure provides a lift truck weighing system that includes a plurality of sensors configured to measure forces acting on a lift truck. In particular, the sensors are secured at one or more interfaces between a plurality of axles and a chassis of the lift truck. In some examples, the sensors are secured to and/or incorporated with a plurality of axles configured to support the lift truck wheels, such as to or within the axles.
Claims12
A lift truck weighing system for a lift truck including a plurality of axles and a chassis, comprising:
- a plurality of sensors configured to measure forces acting on the lift truck;
- a plurality of sensor mounts arranged between the plurality of axles and the chassis, the plurality of sensor mounts configured to secure the plurality of sensors and the plurality of axles to the chassis of the lift truck;
- and
- control circuitry configured to:
- receive force measurements from the plurality of sensors;
- calculate a change in force at one or more axles of the plurality of axles;
- determine a weight distribution on the lift truck based on the calculated change;
- compare the weight distribution to one or more threshold weight distribution plans;
- and
- determine whether the weight distribution exceeds a threshold weight distribution plan.
