The 10 Largest Dump Trucks - The Kings of Capacity

10 Of The World's Largest Dump Trucks

Photography by The Diesel Power Staff

The '08 Ford Super Duty F-450 6.4L is rated to haul a maximum payload of 6,120 pounds. Not bad for a street-legal rig that can supposedly fit into a shopping mall parking space, but imagine trucks that can haul more than 130 times that much weight in the bed, and you've got the Kings of Capacity. These massive "Off-Highway" mining dump trucks boast diesel engines that weigh as much as 25,000 pounds, have as many as 12 turbochargers, and make more than 10,000 lb-ft of torque. The trucks stand more than two stories tall, ride on 63-inch tires, and are stopped with the assistance of multiple-disc, oil-cooled brakes. Most of these trucks use hybrid diesel-electric drive systems to maximize efficiency and power delivery. To support payloads of up to 400 tons, these massive haulers have frame widths and depths that are measured in feet, not inches. The GVOW (gross vehicle operating weight) can exceed more than 650 tons. In fact, most of these dump trucks are so big that the parts have to be shipped to the job site so the trucks can be built on-site. Here are 10 of the highest-capacity trucks being sold today in their most powerful configurations.

Some of the QSK's come with two less turbos and only produce 2700 hp but that's still impressive
