100kVA Dual-Axle Heavy-Duty Open Frame Generator for Mining & Municipal Emergency

Product Overview

WOPUSAI 100kVA open-frame trailer diesel generator set adopts dual-axle four-wheel heavy-duty chassis with all-steel reinforced open frame, built for medium-to-high power outdoor mobile scenarios with high heat dissipation and frequent relocation demands. Integrating heavy traction assembly, multi-stage damping base and heavy-duty all-steel open rack, it delivers strong load-bearing capacity and convenient maintenance, ready for direct outdoor operation. It can be towed to large infrastructure sites, mining areas, municipal emergency rescue spots and medium-term construction projects, delivering stable power continuously on gravel roads and uneven sites. Widely used in engineering construction, field mining, municipal emergency support and medium-long term power rental.

• Power: 100kVA
• Certifications: CE, ISO, MA, CNAS
• Typical Applications: Large infrastructure construction, mining operations, municipal emergency rescue, road & bridge engineering, medium-term power rental

Product Showcase

This unit features an integrally welded heavy-duty steel open frame made of thickened carbon steel channel via full penetration welding, delivering high-strength load-bearing performance and structural rigidity. The fully open layout eliminates heat retention of enclosed cabins, with all core components fully exposed for direct inspection, fault diagnosis and component replacement without cabinet disassembly. The dual-axle four-wheel chassis adopts thickened integral load-bearing beam with balanced axle load design, adapting to rough mine roads, gravel construction sites and long-distance highway transportation. It is fitted with heavy-duty traction coupling, multi-point manual support legs and enhanced mechanical braking system for stable operation. Control panel and output terminals are centrally arranged on the frame side with basic splash protection. Multi-point heavy-duty damping devices at the base reduce vibration during towing and continuous operation.

Key Specifications

Open Frame & Mobile Technology

Optimized for 100kVA frequent relocation and long continuous operation scenarios.

1. Heavy-duty Open Frame Structure

Fully welded channel steel structure with high rigidity and load capacity. Open design realizes natural convection heat dissipation, suitable for long-hour continuous operation in high-temperature field environments. Full component visibility streamlines daily inspection and troubleshooting without cabinet dismantling.

2. Dual-axle Four-wheel Heavy Load Chassis

Balanced load distribution with heavy-duty off-road tires and widened axle design, steadily bearing full unit weight and adapting to gravel, muddy mine roads and long-distance highway hauling. Standard heavy-duty traction connector matches various towing vehicles for fast relocation between large work zones.

3. Multi-stage Damping & Vibration Isolation

Multiple sets of heavy-duty shock absorbers installed between unit and trailer frame filter road vibration during towing and reduce operational resonance, protecting internal components and maintaining stable operation on uneven pavements and construction sites.

4. Reinforced All-steel Construction

Integral full-welding process enhances structural strength and load-bearing capacity. The chassis bottom is reinforced with heavy-duty steel plate for extended service life on rough road conditions.
