What is the weight of a full dump truck?

Answer 1

That depends on the weight rating of the dump truck, the configuration, and state laws in relation to permissible weight with lift axles. For a single axle, the federal regs permit 33,000 lbs. gross weight, but states may allow up to 40,000 lbs. For a tandem axle, 54,000 lbs. is going to be the max permissible gross weight. For tri axles, quad axles, quint axles, and centipedes, it varies by state. Some states allow a tri-axle to gross 70,000 lbs, some states, you need a quint axle to be able to gross as much.

There are more options if you're talking about an "off-highway" haul truck. The weight and hauling capacity of these monsters continues to climb compared to those that will pass a DOT highway inspection. The Komatsu 930E has a curb weight of about 580 tons, and it has a capacity of about 290 tons. How much does a full dump truck weigh? A lot. And a specific question will allow Wikians to make a more specific response.
