50kVA Three-Wheel Maneuverable Generator for Municipal Repair & Temporary Engineering

Product Overview

WOPUSAI 50kVA open-frame trailer diesel generator set adopts a three-wheel steering chassis matched with an all-steel open frame structure, specially built for outdoor temporary power scenarios with high heat dissipation requirements and low noise restrictions. The unit integrates a front steering wheel + rear dual load-bearing wheel layout, a damping base and heavy-duty open steel rack, featuring convenient maintenance and efficient heat dissipation, and can be put into operation directly outdoors without additional installation. It can be easily towed to urban road maintenance sites, small construction projects, outdoor operation sites and temporary construction areas, delivering stable power output continuously in complex field environments such as rain and uneven roads. It is widely used in engineering construction, municipal emergency maintenance, field operations and temporary power supply scenarios.

• Power: 50kVA
• Certifications: CE, ISO, MA, CNAS
• Typical Applications: Municipal maintenance, small construction sites, field operations, temporary engineering projects

Product Showcase

This 50kVA three-wheel open-frame genset adopts an integrated welded heavy-duty steel open frame. The frame is made of thickened carbon steel channel steel through full welding, with high-strength load-bearing performance, and the surface adopts standard industrial steel finishing. The fully open layout eliminates the obstruction of the enclosed cabin, all components are clearly visible, and daily inspection, fault troubleshooting and component replacement are more direct and convenient. The three-wheel chassis adopts a front steering wheel + rear double load-bearing wheel design, with a balanced load-bearing frame, adapting to narrow urban streets, rural roads and small construction sites. It is equipped with a standard traction connector, manual support legs and a mechanical braking system to ensure stable parking and operation. The control panel and output terminals are centrally arranged on the side of the frame, which is easy to operate and has basic rainproof protection. The unit base is equipped with a multi-point vibration damping device to reduce vibration transmission during transportation and operation.

Key Specifications

Open Frame & Mobile Technology: Built for Outdoor Efficient Mobile Power

WOPUSAI three-wheel open-frame trailer genset adopts targeted open mobile power technology, optimized for 50kVA small-power frequent transfer and outdoor temporary operation scenarios.

1. Fully Open Frame Structure

The open rack adopts a fully welded channel steel structure with high load-bearing strength. The fully open design eliminates the heat accumulation problem of enclosed cabins, with natural convection heat dissipation, adapting to long-time continuous operation under high temperature environment. The open layout makes all components visible at a glance, and daily maintenance and fault handling are more efficient, without disassembly of the cabinet.

2. Three-wheel Flexible Steering Chassis

The chassis adopts a front single steering wheel + rear double load-bearing wheel layout, with small turning radius and strong trafficability, adapting to narrow streets, rural roads and small construction sites. The lightweight frame design reduces the overall weight, and can be towed by ordinary vehicles, realizing fast transfer between scattered work points.

3. Multi-point Damping Base Structure

Multi-group heavy-duty shock absorbers are installed between the generator unit and the trailer frame to filter road vibration during towing and reduce operation resonance. It protects internal components from vibration damage during short-distance transportation, and maintains stable operation on uneven pavement and construction sites.

4. Reinforced Chassis Construction

The whole frame and chassis adopt integral welding process for enhanced structural rigidity. The chassis bottom is reinforced with heavy-duty plate, adapting to gravel and muddy road conditions for long service life.

🎯 Application Scenarios

• Municipal Operation & Maintenance: Mobile power for urban road maintenance, pipeline repair and emergency rush-repair projects
