80kVA Four-Wheel Open Frame Generator for Rural Infrastructure & Water Conservancy Projects

Product Overview

WOPUSAI 80kVA open-frame trailer diesel generator set adopts dual-axle four-wheel chassis with all-steel open frame, built for medium-power outdoor mobile scenarios with balanced load and mobility. Integrating standard traction assembly, modular damping base and heavy-duty steel rack, it delivers high cost performance and wide adaptability, ready for direct outdoor operation. It can be towed to medium construction sites, rental fleets, municipal projects and factory standby locations, delivering stable power on gravel roads and uneven sites. Widely used in building engineering, equipment rental, municipal maintenance and medium-term backup scenarios.

• Power: 80kVA
• Certifications: CE, ISO, MA, CNAS
• Typical Applications: Medium construction sites, power rental fleets, municipal engineering, factory standby, small infrastructure projects

Product Showcase

This unit features a fully welded heavy-duty steel open frame made of thickened carbon steel channel, delivering reliable load-bearing capacity and structural rigidity. The fully open layout eliminates heat retention of enclosed cabins, with all core components exposed for direct inspection, troubleshooting and component replacement. The dual-axle four-wheel chassis adopts balanced load-bearing beam design, adapting to construction roads, suburban roads and medium-distance highway transport. It is fitted with standard traction coupling, two-point manual support legs and mechanical braking system for stable operation. Control panel and output terminals are centrally arranged on the frame side with basic splash protection. Multi-point damping devices at the base reduce vibration during towing and operation.

Key Specifications

Open Frame & Mobile Technology

Optimized for 80kVA daily relocation and medium-load continuous operation.

1. Standard Open Frame Structure

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

2. Dual-axle Four-wheel Chassis

Balanced load distribution with standard heavy-duty tires, steadily bearing full unit weight and adapting to gravel, muddy roads and medium-distance highway hauling. Standard traction connector matches common towing vehicles for flexible relocation between work zones.

3. Modular Damping Base

Multiple sets of standard 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.

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 roads.

🎯 Application Scenarios

• Medium Construction Projects: Continuous mobile power for building construction, road repair and small infrastructure engineering
