Abstract

A load sensor for a concrete conveyor having a tremie which sounds a signal and releases the tremie in case the tremie becomes overloaded. The device has a U-shaped deflection yoke between the tremie and the conveyor which deflects under the weight of the tremie to close switches and actuate the appropriate safety device. All parts are protected from concrete to insure proper functioning.
