Why Choose Our Mobile Trailer Generators?
Mobile trailer generators combine the sound performance of our Silent Type range with the deployment flexibility of a road-mobile platform — the ideal solution for operations that move.
Deploy Anywhere, Relocate Anytime
The heavy-duty trailer chassis allows the generator to be towed between project sites, eliminating the need to own separate generator assets at each location. One unit can serve multiple sites sequentially, significantly reducing capital expenditure for multi-site operators.
Same Engine Quality as Fixed Units
Trailer generators use identical Weifang diesel engines as our open and silent type ranges — the same proven powertrains used in hundreds of thousands of installations worldwide. There is no engineering compromise in the generator itself due to the trailer format.
Advanced Control Systems
Every trailer generator up to 150kW ships with the standard Four Protection System controller, with an optional Full Auto ATS upgrade. For models 200kW and above, the Full Auto ATS system comes standard, allowing fully automatic start, connect, and shutdown on grid failure.
Applications of Mobile Trailer Generator Sets
Mobile trailer generators are the standard choice for any application where the power source must be regularly relocated. From construction site power to outdoor concert stages and emergency disaster response, the trailer format provides maximum operational flexibility without sacrificing generator performance.
Frequently Asked Questions
What towing vehicle is required for the trailer generator?
For units up to 150kW, a standard heavy pickup truck or medium commercial vehicle with an appropriate tow rating is sufficient. For units from 200kW upwards (trailer weight 3,000–4,000+ kg), a heavy commercial truck with appropriate tow capacity and coupling is required. We recommend confirming tow vehicle specifications with your local transport authority.
Can the trailer generator be used while stationary for extended periods?
Yes. The trailer generator is equally effective as a fixed installation when deployed with stabiliser jacks and connected to a permanent or semi-permanent load. Many customers use trailer generators as long-term site power solutions with the option to relocate at end-of-project.
Do you offer wholesale pricing for fleet or bulk orders?
Yes. Power rental companies, construction contractors, and EPC firms regularly purchase multiple trailer generator units. As a direct manufacturer, we offer significant pricing advantages on fleet orders of 3 or more units. Contact us with your fleet requirements and timeline for a structured proposal.
