What does the term "curb weight" refer to?

The term "curb weight" specifically refers to the weight of a vehicle or apparatus when it is empty and not loaded with any cargo or passengers. This includes all necessary fluids such as oil, fuel, and water that are needed for operation, making it distinct from other weight measurements like the maximum load capacity or the weight when fully loaded. Understanding curb weight is essential for pump operators as it provides a baseline for assessing the overall weight and balance of the equipment, ensuring proper handling and safety during operations. It is critical for operators to recognize the curb weight when calculating load limits or configuring the apparatus for specific tasks.
