Abstract

An ejector truck requires an ejector mechanism to remove hauled material from the ejector truck body. Often, these ejector mechanisms are costly and require precise manufacturing and maintenance because they include a telescoping linear actuator. The present invention provides a method and apparatus of a multi-actuator ejection mechanism. The multi-actuator ejection mechanism includes an anchor member, an ejection carriage, an ejector blade, a first linear actuator, and a second linear actuator. The ejector blade is located a predetermined distance from the anchor member and is adapted to move longitudinally with respect to the anchor member. The first linear actuator has a first end secured to the anchor member and a second end secured to the ejection carriage, and is adapted to move the ejection carriage longitudinally with respect to the anchor member. The second linear actuator has a first end secured to the ejection carriage and a second end secured to the ejector blade, and is adapted to move the ejector blade with respect to the ejection carriage. The multi-actuator ejection mechanism of the present invention uses multiple single-stage linear actuators instead of a single telescoping/multiple-stage linear actuator.
