Abstract

PURPOSE: To make it possible to prevent abnormal bending moment loaded on a lifting frame, by providing a pressure detector to the lifting frame to automatically control a running speed.
CONSTITUTION: Because bending moment received by a lifting frame 9 is changed by an amount of precipitate 50 accumulated on the bottom of a precipitation basin 1, load applied to a pressure detecting element 44, which is mounted between the lifting frame 9 and a machine frame 28, through a guide roller 46 and a roller support member 45 is also changed. When an amount of the precipitate 50 is much, the load corresponding to the accumulated precipitate 50 is applied to a pressure detector 30 through the lifting frame 9. A repelling force signal from the pressure detector 30 is amplified by an amplifier through a control unit and applied to a PI controller. Because a set signal is applied to the PI controller, a difference signal with the repelling force signal is applied to a running speed setting instrument and a running drive apparatus 48 is operated by a signal order corresponding to load through a motor control panel.
