Additional Information
The Chelsea 272 Series was developed to replace and consolidate several earlier Chelsea medium-duty PTO families, including the 230, 231, 236, 238, 270, and 271 series. This makes it a direct upgrade path for fleet operators running any of those earlier units. The 272 Series is suited for aerial equipment, construction machinery, water trucks, towing and recovery rigs, defense, material handling, and water drilling applications. Smart-Start technology is available for high-torque start-up conditions common in hydraulic pump applications.
