Daimler Trucks North America is now offering the Hadley SmartValve electronic height control system as an option on new trucks.

SmartValve, introduced as a retrofit system in 2013, is designed to make drop-and-hook operations faster, easier and safer.

It reduces back strain and injuries for the driver, who doesn’t need to struggle against the weight of the trailer when cranking landing gear, the company said.

“The Hadley SmartValve was developed to enhance driver comfort and safety,” Jim Green, president of Hadley, said in a statement. “For the fleet owners the cost savings and driver satisfaction are an added bonus.”
