The TR40-II uses a 1,400 mm front steel drum and four 10.5/80-16 rear pneumatic tires in one machine. The front drum handles the primary rolling and hydraulic vibration, while the rear tire set follows the same working path. As a combination asphalt roller, the TR40-II brings steel-drum and pneumatic-tire compaction together in one machine.
Unlike a double-vibratory-drum configuration, the TR40-II concentrates hydraulic vibration on the front steel drum. The rear pneumatic tires remain non-vibrating, giving the machine a clear division between front-drum vibration and rear-tire rolling during operation.
The TR40-II is arranged for straightforward access to its main operating and hydraulic functions. Travel, front-drum vibration, and water spraying can be controlled from the operator's station, keeping the main working functions within easy reach during daily compaction work.
The front steel drum is positioned directly in the operator's working view, providing a clear view of the compaction area ahead. The simple control layout allows the operator to manage travel speed, front-drum vibration, and spraying while keeping attention on the working surface.
