Generadores portátiles

A portable generator is a mobile power unit that converts diesel fuel into reliable electrical power for tools, lighting, and equipment on jobsites without grid access. Bobcat portable generators deliver dependable performance wherever you need electricity — construction sites, events, disaster recovery, or remote operations. 

Towable, diesel-powered generators range from 25–1140 kVA, providing single- and three-phase power to run everything from hand tools to jobsite trailers and tower cranes. Each model is built with: 

• Heavy-duty enclosures and sound attenuation for quiet operation 
• Automatic voltage regulation (AVR) for steady, clean output 
• Tier 4 diesel engines for efficiency and emissions compliance 
• Easy-access service panels and long runtimes to minimize downtime 

Common alternative terms include mobile generator, towable generator, and diesel portable power unit. 

Selecting the right generator depends on your power demand and operating conditions. Consider the following:

• Power output: Match the generator’s kW, kVA, or amperage rating to the total running load of your equipment. 
• Voltage needs: Choose single-phase power for smaller tools and lighting or three-phase for industrial applications. 
• Runtime requirements: Larger fuel tanks support long shifts without refueling. 
• Mobility and transport: Compact, trailer-mounted units are ideal for moving between jobsites. 
• Environmental factors: Sound-attenuated, weather-protected enclosures are essential for urban or harsh environments. 

Authorized Bobcat dealers can help calculate total load and recommend the best generator for your application. 

Portable generators stand apart for their flexibility and reliability: 

• Compared to standby generators: Portable units are mobile and designed for temporary or transportable use, while standby generators are fixed installations for permanent backup power. 
• Compared to inverter generators: Industrial portable generators offer far greater capacity (25–570 kVA) and three-phase capability, suited for heavy-duty equipment rather than small electronics. Most small portable generators are inverters, typically only offer single-phase and provide less than 15 kW output. 
• Compared to tow-behind light towers: Light towers primary electrical output is for integrated lighting. While some light towers offer on-board generators, they generally have lower kW output, are limited to single-phase and do not have the same connection options as dedicated mobile generators.   

Portable generators provide scalable, rugged power for any jobsite or emergency condition.

Operation is straightforward but always review the operation and maintenance manual.

Follow these steps for safe and efficient operation: 

Prepare the generator 

• Place on level ground, chock the wheels, and connect the grounding cable. 
• Check engine oil, coolant, and fuel levels. 

Start the engine 

• Ensure all loads and the main breaker are OFF. 
• Turn battery disconnect and control power ON. 
• Press the RUN button and allow the engine to warm up. 

Connect loads 

• Wait for voltage to stabilize. 
• Turn the main breaker ON and connect equipment. 

Monitor operation 

• Check gauges and alarms regularly. 
• Keep doors closed for proper cooling. 

Important: Always follow the operation and maintenance manual for detailed operating instructions. Never operate indoors without ventilation, and keep the area clear of flammable materials. 

Bobcat portable generators are available across a full power range to fit light-duty, mid-range, and heavy industrial needs: 

• PG25 – PG150: Compact, towable models producing 25–150 kVA, ideal for residential construction, small jobsite power, and jobsite trailers (lighting, HVAC, computers, etc). 
• PG240 – PG325: Mid-size units feature strong motor starting capability and delivering 200–325 kVA for roadwork, utilities, and tower cranes. 
• PG400 – PG1140: Large diesel models producing 400–1140 kVA (e.g., PG570 = 570 kVA / 456 kW) with load management technology and paralleling for major construction projects or emergency power applications. 

Every Bobcat portable generator is built for easy towing, quiet operation, and superior efficiency in the field.
