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.
