Versatility is essential for contractors to make the most of their equipment. Oscillation offers a wide range of applications from large expressway projects to smaller, yet critical, urban-type work. The front drum utilizes vertical vibration that delivers the amplitudes and frequency options for thicker lifts and tough mix designs, while the oscillation system on the rear drum gently massages the asphalt with a back and forth motion that performs effectively on thin lifts and near sensitive structures such as buildings, bridge decks, and over underground utilities like fiber-optics, electric, water, and gas lines.
Caterpillar Oscillation Design
The design combines Caterpillar’s high-performance vertical vibration on the front drum with new oscillation technology on the rear drum. The front drum with vertical vibration is available in two amplitude, five amplitude, or Versa-Vibe™ systems that provides initial compaction, while the rear drum with oscillation continues the excellent performance for optimal smoothness and density.
The oscillatory system utilizes the proven pod-style eccentric weight technology developed by Caterpillar and has a 2 year/2000 hour service interval that helps contractors maximize uptime and limit routine maintenance costs. A durable power-transmission employs a unique belt-drive system that delivers 2-times the load capacity of timing belt systems for more reliable operation. In addition, the hardened drum shell offers exceptional long-term strength on a variety of mix designs and delivers outstanding mat texture, density, and smoothness.
