Mobile Trailer Generator
A mobile trailer generator mounts a silent genset on a road-legal braked trailer, so a truck or pickup can tow it between sites, events and rental jobs and it is ready to run on arrival. OCALWA supplies trailer gensets from 20 to 150 kVA, matched to your load and towing rules, from a verified ISO 9001 + CE factory.
Power that follows the job
A silent-canopy genset sits on a braked road trailer with a tow hitch, jockey wheel, support jacks, lights and mudguards, plus a larger fuel tank for a full shift between refuels. Sockets and an output panel let crews plug in on site quickly.
It is the standard choice for rental fleets, construction, outdoor events and disaster response, where the same unit moves from job to job. Options include a distribution board, extra sockets and remote monitoring.

Configurations & options
Rating, engine tier, voltage and enclosure are matched to your load and grid. Send us the kW/kVA you need, whether it is prime or standby, your frequency/voltage and site conditions and we specify the right set.
Why choose a trailer generator
One unit, many sites
Tow it from job to job instead of buying a set per site, ideal for rental fleets and rotating construction work.
Ready to run on arrival
Silent canopy, fuel and output panel are all onboard, so crews level it, plug in and go.
Rental-fleet friendly
Rugged road kit, easy hookup and remote monitoring make it a strong revenue unit for equipment rental businesses.

Frequently asked questions
Trailers are built to common road standards with brakes, lights, reflectors and a rated hitch, but registration and towing rules vary by country and by weight. Tell us your market and gross weight and we confirm the hitch type, braking and lighting so it can be plated and towed legally.
The onboard tank is sized for a full working shift, typically 8 to 12 hours at usual load; run time depends on set size and how heavily it is loaded. If you need longer autonomy for events or remote work we fit a larger tank or an external tank connection.
The set is built with your choice from several established international diesel engine brands, paired with a brushless, self-exciting alternator with AVR voltage regulation. You pick the engine tier to match your budget, fuel and local service network; we confirm the exact pairing and its rating before order.
Yes. We build 50 Hz or 60 Hz and set the voltage to your grid (for example 120/240V, 220/380V or 240/416V, single or three phase). Latin America is mostly 60 Hz. Tell us your country's frequency, voltage and phase and we configure the alternator and controller accordingly.
The set uses mainstream international engines whose oil, fuel and air filters, belts and pumps are widely stocked across Latin America. We also supply a starter spares kit and can re-order alternator parts, the controller, AVR and hoses so downtime stays short.
Standby rating is for backup when the grid fails, used a limited number of hours a year at varying load. Prime rating is for continuous running as the main power source, at a lower rated output for the same set. If it is your only power, size on prime; if it is grid backup, size on standby. We rate it to how you will actually run it.
Yes. Beyond the bare set we supply the automatic transfer switch (ATS), starting batteries, connection cables, remote monitoring and a starter spares kit, from a verified factory (ISO 9001 + CE). OCALWA arranges container or RORO shipping and full export documentation, and regularly ships to Colombia, Venezuela, Argentina, Paraguay and the Dominican Republic, quoting FOB, CFR or CIF.
