300kVA Rainproof Trailer Diesel Generator for Bridge Engineering & Mega Construction Sites

Product Overview

The WOPUSAI 300kVA rainproof trailer diesel generator adopts an infrastructure-grade rainproof enclosure and heavy-duty long-haul chassis, built for mega construction and long-distance mobile power scenarios. The base unit features an optimized long-haul structure and high-efficiency heat dissipation for long-duration continuous operation. Silent canopy upgrade is available for urban construction areas. It can be towed to mega construction sites, bridge engineering and long-duration infrastructure projects.

• Power: 300kVA
• Certifications: CE, ISO, MA, CNAS
• Typical Applications: Mega infrastructure, bridge engineering, long-duration projects, highway construction, large-scale rental

Product Showcase

The unit features an infrastructure-grade welded steel rainproof enclosure made of extra-thick load-bearing steel plate via full penetration welding, delivering high load capacity and structural stability for long-haul transport. Optimized large-flow ventilation and drainage system ensures reliable protection during long-term outdoor deployment. Wide double access doors support professional overhaul. The heavy-duty long-haul chassis supports 2/3/4-wheel configurations with highway heavy-load tires, adapting to long-distance highway transport and construction sites. It is equipped with a standard heavy-duty traction coupling, multi-point stable support legs and reliable braking system. Side-mounted professional control panel has basic splash protection. Multi-stage optimized damping reduces vibration during long-haul towing.
