Zusammenfassung:PROBLEM TO BE SOLVED: To provide a conveyance device with a clogging detection function for detecting clogging of a conveyance pipe. SOLUTION: The conveyance device for concrete 3 is provided for carrying the concrete 3 from the upper part of a slope 2 to the lower part to supply it to a construction site at the lower part of the slope 2. It comprises a sensor for measuring a load given by the weight of the concrete 3 in the conveyance pipe 12 for the concrete 3, and a clogging determining means. Information read by the sensor is compared with a clogging threshold value predicted from an experimental value, and the clogging of the conveyance pipe 12 is estimated and warned by an output part 18 depending on whether it exceeds the threshold value or not. In accordance with a command from a monitoring terminal 17, the operation is controlled via a motor driving control panel 15. COPYRIGHT: (C)2009,JPO&INPIT
