Safety Tips and Fun Facts

Did you know a fully loaded mixer truck (10 yard load) weighs up to 72,000 pounds?

For job site access, make sure you have adequate clearance for a typical mixer (9 feet wide, 12.5 feet high, 23 feet long).

The undercarriage of a loaded mixer is typically no more than 9 inches off the ground.
