A new line of concrete mixer trucks includes the Pro Series standard and a Bridge Maxx Series with a booster axle. Both bodies can be mounted on any heavy truck chassis, the company says. Both drums have a standard 43-inch discharge opening and a 47-inch paver discharge opening. The drum is 3/16-inch thick with a 1/4-inch-thick one-piece pressed and dished head 78 inches in diameter. The ErgonicMix Control (EMC) is a fully programmable control system that balances engine speed with hydraulic pump output to achieve the optimum drum speed, the company says.
