• Typical Applications: Large infrastructure projects, mining sites, municipal emergency backup, long-term power rental, large field operations

Product Showcase

This 250kVA silent trailer genset is fitted with heavy reinforced silent cabin. The enclosure uses full deep penetration welding and multi-layer acoustic sealing construction. Optimized large-capacity rain gutter plus full-perimeter soundproof waterproof rubber strips on door frames, which suppress noise leakage while blocking rainwater and dust infiltration. The heavy-duty four-wheel dual-axle trailer chassis adopts thickened integral load-bearing beam frame with balanced axle load design, adapting to rough mine roads and long-distance highway transport. It is equipped with heavy-duty traction coupling, multi-point manual support legs and enhanced mechanical braking system to guarantee stable stationary operation. Extra-wide double maintenance hatches are arranged on both sides of the cabin, offering ample operating space for inspection and component overhaul. Waterproof enclosed control panel and reserved external output sockets are mounted on the side for safe field operation. The cabin interior is filled with thick multi-density sound-absorbing material. Multi-layer vibration isolators are installed between unit base and trailer frame to cut vibration transmission and reduce operational noise.

Key Specifications

Silent & Mobile Technology: Built for Heavy-duty Outdoor Low-noise Operation

WOPUSAI silent trailer genset adopts high-power mobile noise reduction technology, optimized for 250kVA long-running, frequent relocation heavy-load working scenarios.

1. Reinforced Silent Rainproof Cabin Structure

The silent housing adopts fully welded heavy-duty waterproof construction with layered acoustic design. Large inclined gutter system quickly drains rainwater and avoids ponding. Door frames embedded with high resilience sound-water dual-purpose sealing strips to block rain, dust and noise leakage. Air inlet and outlet adopt large-size silencer baffles, lowering airflow noise and preventing rain splash inside the cabin while ensuring sufficient heat dissipation airflow for long-hour heavy load operation.

2. Dual-axle Four-wheel Heavy Load Chassis

Integral welded thick load-bearing longitudinal beam, fitted with four heavy-duty off-road tires and dual axle load balance design. The structure can bear full machine weight steadily and adapt to gravel, muddy mine roads and highway long-distance hauling. Standard heavy traction connector matches various towing vehicles, supporting fast relocation between large working zones.

3. Multi-stage Vibration Isolation & Noise Suppression

Multiple heavy shock absorbers are installed between trailer frame and cabin base to filter road vibration during towing. Additional vibration isolation mounts between the genset and cabin base reduce resonance and mechanical noise transmission. This layered protection prevents internal components from vibration damage during cross-region transportation and maintains stable low-noise running on uneven field ground.

4. Heavy-duty Anti-corrosion Surface Treatment

The cabin and trailer chassis go through multi-layer anti-rust primer and weather-resistant topcoat treatment, resisting erosion from rain, mud, mineral dust and outdoor UV radiation. Chassis bottom is sprayed with thick anti-stone coating to extend service life under severe field working conditions.
