Manufacturer: Bobcat
Category: Power Generation
Model: PG1140WCU-2B-T4F
Emissions: EPA Tier 4 Final

Overview

The Bobcat PG1140WCU-2B-T4F is a heavy-duty mobile generator system engineered for large-scale prime power applications where reliability, flexibility, and extended runtime are critical. Delivering up to 1140 kVA / 912 kW of prime power, the system combines two Cummins X15 Tier 4 Final engines, dual Leroy Somer alternators, integrated switchgear, and a 48-foot galvanized flatbed trailer into a rental-ready package.

Designed specifically for rental, construction, special events, industrial operations, and other high-demand temporary power applications, the PG1140 provides up to 27.8 hours of runtime at 75% load. Its sound-attenuated enclosure, advanced CoolBox+ cooling system, onboard fuel and DEF storage, and centralized controls make it well suited for long-duration deployments and demanding operating environments.
