Construction, emergency repair and event work changes location repeatedly
The unit moves between worksites, plants or service points and can begin work after stabilization, grounding and connection.
Product Range / Towable Multi-Site Power
Trailer-Mounted Diesel Generator Sets
A diesel generator set, low-noise weatherproof enclosure and trailer chassis combined as a redeployable temporary power source. It suits construction, emergency repair, events and maintenance outages, provided the load, tow vehicle, route, brakes, stabilizers, connections and required runtime are considered together.

Why Choose a Trailer-Mounted Set
When one power source must serve several sites, a purpose-built trailer is safer and more efficient than repeated temporary handling
The value is the ability to dispatch, stabilize and connect the set quickly—not simply the addition of wheels. The product must satisfy electrical, road-movement and on-site operating requirements at the same time.
One power source must support several temporary load groups
Suitable for pumps, welders, lighting, temporary offices and maintenance loads without purchasing a fixed generator for every site.
Tow vehicle, gross weight and road requirements are not yet defined
Axles, brakes, hitch height, road lighting and markings must match the vehicle and local rules. Rating alone is not enough to specify a trailer.
The unit is intended as permanent standby power for a critical facility
Hospitals, data centers and other fixed critical loads still require a complete ATS, fuel, distribution, redundancy and scheduled-testing system.
Trailer Configuration Range
From compact single-axle units to heavy multi-axle and highway trailers, choose around rating and movement frequency
Chassis type follows total weight, road condition, turning space, dispatch frequency and stability during operation. Larger sets need stronger axles, brakes and stabilizers.
Two-Wheel / Single-Axle Trailer
For smaller ratings, short movements within a site or occasional relocation, emphasizing compact steering and quick deployment.
Four-Wheel Steering Trailer
Can use a movable drawbar and 180-degree turntable for easier positioning in plants, worksites and confined areas.
Four-, Six- or Eight-Wheel Multi-Axle Chassis
For higher ratings and greater operating weight, configured around axle loads, tires, braking and stabilization.
High-Speed Trailer
For frequent and longer-distance road moves, with vehicle connection, braking, lighting and compliance reviewed separately.
Available ratings cover approximately 15kW to 1000kW. Final rating, enclosure, chassis, axle count, braking and road configuration are confirmed against operating weight, travel distance, tow vehicle, local requirements and site conditions.
Ratings and Engine Platforms
As rating increases, total weight, axle loading and braking become primary design inputs for the mobile system
Temporary power still requires starting and power-quality checks. The combination of pumps, welders, compressors and sensitive equipment determines both generator capacity and connection method.
15–100kWLighting, small pumps, telecom, events and light construction loads, with priority on compact size and quick connection.
100–300kWMedium construction, plant maintenance and temporary production loads where motor starting and chassis capacity must be checked.
300–600kWLarge pumps, industrial emergency work and transition power, requiring heavy-duty axles, braking, fuel autonomy and cable interfaces.
600–1000kWHigh-capacity temporary power where route access, towing capability, site leveling and safety separation require a project-specific review.

Mobile Structure and Customer Value
Eight movement and operating details determine whether the unit can travel safely and supply stable power
Road safety matters in transit; stable placement and quick connection matter on site. If any one area is missing, mobility can become an additional risk rather than a benefit.
Hitch and Steering
Hitch type, towing height and turntable design affect vehicle matching and maneuvering in confined areas.
Axles, Tires and Axle Load
Operating weight must be distributed across axles and tires with margin for road and ground capacity.
Mechanical or Air Brakes and Road Lighting
Service brakes, parking brakes, lighting and markings follow the travel distance and applicable local requirements.
Stabilizers and Leveling
Mechanical or hydraulic supports stabilize the chassis during operation so slope and vibration do not affect the equipment.
Low-Noise Weatherproof Enclosure
The enclosure balances outdoor protection, acoustics, airflow and safe separation from nearby personnel.
Ventilation and Service Doors
Front-to-rear airflow and two-sided service access support cooling, inspection and repeated maintenance across sites.
Fuel and Runtime
A base or larger-capacity tank is selected around task duration, refueling access and transport weight.
Connections, Grounding and Emergency Stop
Quick-connect panel, cables, grounding, protection and emergency stop should be configured and checked before dispatch.
Six Deployment Inputs
Confirm vehicle and load before dispatch so on-site work is limited to leveling, grounding, connection and checks
Capacity, starting and power quality
List pumps, welders, compressors, lighting and sensitive equipment to define maximum simultaneous load and starting method.
Frequency, voltage and quick connection
Confirm 50Hz/60Hz, voltage and phases, plugs or terminals, main breaker, cable length and grounding method.
Vehicle, gross weight and route
Check towing capacity, hitch height, axle load, braking, tires, route and applicable road requirements.
Slope, ground capacity and safety separation
The parking area must be levelable, support the weight, allow clean airflow and exhaust, and maintain distance from people and combustibles.
Runtime, fuel and acoustic boundary
Use continuous operating hours, refueling access, nighttime duty and nearby receptors to select the tank and enclosure.
Operators, maintenance and remote records
Define responsibility for towing, connection, routine checks, operating records, spare parts and cross-site maintenance.
Choosing the Mobility Format
Trailers suit task-based relocation, truck-mounted stations suit rapid response, and acoustic sets suit fixed outdoor duty
| Comparison | Trailer-Mounted Set | Truck-Mounted Power Station | Fixed Sound-Attenuated Set |
|---|---|---|---|
| Movement | Towed by a matched vehicle and dispatched between assignments. | Generator, distribution and operator space integrated on a dedicated vehicle. | Remains at the installed location and is not designed for frequent moves. |
| Primary value | Flexible acquisition and dispatch, allowing one power source to serve several temporary sites. | Faster deployment and emergency response, with more operating facilities carried on the vehicle. | Straightforward fixed outdoor acoustics, weather protection and routine service. |
| Confirm first | Tow vehicle, route, brakes, leveling, grounding and connections. | Vehicle compliance, onboard distribution, cable handling, personnel space and maintenance. | Acoustics, cooling, foundation, fuel and fixed system interfaces. |
| Typical tasks | Construction, emergency repair, maintenance transitions, events and rental fleets. | Public emergency response, specialist support and frequent fast-response assignments. | Hotels, hospitals, schools, shopping centers and fixed equipment areas. |
Typical Project Tasks
Configure a complete power tool around fast arrival, reliable operation and clean demobilization
Provide a redeployable source for phase-by-phase loads
For pumps, welders, lighting, tools and temporary offices, confirm starting demand, site connection and safety separation.
Take over loads while the fixed system is under maintenance
Prepare cables, grounding and switching in advance, then connect by load priority to avoid extending an outage through on-site decisions.
Control operating and maintenance cost across multiple sites
Standardized interfaces, run-hour tracking, remote alarms and a spare-parts plan improve utilization and reduce operating errors.
