Operators hail cab upgrades

Improving efficiency is new design target.

The study of ergonomics has brought marked changes in areas ranging from workplaces to vehicles. Those whose workplace is a vehicle also expect to find cabs that are more comfortable.

Manufacturers are responding with interiors that come much closer to those of the cars and pickups that bring operators to worksites. Designers are reducing noise, improving comfort, and offering better sight lines as they attempt to make operators more efficient by reducing fatigue.
