Mining trucks are heavy industrial machinery. They have an enormous impact and weight load on local roads. An ultra-class mining dump truck is typically around 49 feet long, 22 feet high and 29 feet wide. An ordinary two lane road is between 28- 30 feet wide from curb face to curb face. A 28 feet wide road is neighborhood street width.
The second largest mining haul truck can carry a 400 ton of payload and can travel over 42 miles per hour (pictured below).
