A measuring instrument (40) for indicating the load in a gyratory crusher comprises a first measuring device (32, 42) for measuring at least one instanta¬ neous load on the crusher, a second measuring device (44) for measuring the gyrating position of the inner shell (20) relative to the outer shell (22), and a correlating device (48) adapted to match said at least one instanta¬ neous load on the crusher with a corresponding measured gyrating position of the inner shell (20) relative to the outer shell (22).
