The company’s Sand Spreader attachment helps turn the FP5 Flameless Pothole Patcher into a sand spreader in less than an hour. Used in place of the standard material chute or swing auger system, it applies an even coat of sand to the road surface. Sand is held in the unit’s 5.1-cu-yd hopper and transferred via a hydraulically driven auger to the 17.5-in.-diameter poly spinner for distribution. In-cab controls regulate how much sand is being laid down and adjust spinner speed to change the width of the sand coverage from 5 to 34 feet. Bergkamp Inc.
