caterpillar -- 740 Ejector...

The Caterpillar 740 Ejector Articulated Truck is Caterpillar's second generation of articulated haul truck (dump truck) to have a system that pushes material out the back of the body. It is the largest articulated haul truck offered by Caterpillar; larger trucks use a rigid frame system. The ejector uses a 4 cylinder hydraulic ram and blade to dump the material out, a similar system to Cat's wheel tractor-scrapers. The 740 Ejector is sold as separate model from the usual 740.
