Abstract
A truck having a conveyor arrangement and a material spreader and a control mechanism to regulate the speed said conveyor arrangement conveys materials and to regulate the velocity the materials are ejected from said material spreader. The material spreader includes a material guider to guide the trajectory of substantially all of the materials in a direction substantially opposite the direction of forward movement of the truck. The control mechanism also includes a velocity sensor adapted to detect the velocity of the truck and to send a signal indicative of the truck velocity to a velocity controller. The velocity controller sends a signal to the conveyor arrangement and the material spreader which is dependent on the truck velocity to control the conveyor arrangement and the velocity of the materials ejected from the material spreader to obtain a material velocity relative to the ground surface of substantially zero when the truck is moving.
