The Missouri Department of Transportation is the first government agency to be testing a new diesel-electric bucket truck. The bucket truck, used to lift maintenance workers in the air to install signs, fix traffic signals or replace streetlights, is expected to cut fuel costs and smog-producing emissions in half, while also reducing maintenance costs, reducing noise and providing an alternative power source in emergencies. Traditional bucket trucks require the engine to remain running to operate the hydraulic arm that moves the bucket. The new hybrid-electric bucket truck allows the engine to be shut off at a work site, reducing emissions and saving fuel. The trucks are produced by International and Eaton Corporation, and use lithium ion batteries.
