The Caterpillar 740 Ejector Articulated Truck is Caterpillar's second generation of articulated haulers (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.
Total power is 436 hp (325 kW), total operating weight is 162,280 lb (73,610 kg), with the load being 42 short tons (38 tonnes), 37.3 yd3 (28.5 m3) at a 1:1 heap. Top forward speed is 34 mph (55 km/h).
