A device that provides a reading of payload weight during hoisting is called a

• A. Load cell
• B. Gyroscope
• C. Anemometer
• D. Hydrometer

Answer: (A)

Payload weight readings during hoisting come from a load cell. A load cell is a force transducer that measures the load on the crane line or hook, usually using strain gauges that detect deformation when a load is applied. The measured strain is converted into an electrical signal that the crane’s readout or control system translates into the payload weight. This helps prevent overload and supports safe, controlled lifts. The other devices don’t measure weight: a gyroscope tracks orientation, an anemometer measures wind speed, and a hydrometer assesses liquid density.
