E2 Systems' Portable Conveyor attaches to 2.5-cubic-yard wheel loaders, and the maker claims the 60-inch conveyor has outperformed standard material-transfer placer systems by two to one at about one fourth of the cost. It is said to have placed 300 cubic yards of concrete per hour on road grade when supplied by dump trucks hauling 11-cubic-yard loads. The conveyor is operated from inside the cab of the machine using the hydraulic controls and the power of the wheel loader. The concrete conveyor can be detached from the loader and the loader returned to other productive applications. This E2 promotional video shows it at work.
