    Find Generators For Sale

    Generators provide dependable power where grid access is limited or where backup supply is critical to operations. Across construction sites, agricultural properties, mining camps, and residential settings, these units support tools, equipment, and essential systems during outages or off-grid work.


    2026 Caterpillar 3512C Stationary Generator

    Buyers searching for generators for sale will find a wide range of sizes and configurations, from small portable units to large-scale power plant systems. On MachineryTrader.com.au, dealers, contractors, and individual sellers can compare machines based on output, mobility, and application needs.

    Generator Benefits

    • Reliable power supply supports continuous operations in remote or outage-prone areas
    • Wide range of sizes and outputs suits everything from small tools to large facilities
    • Mobile and fixed options allow flexible deployment across jobsites and properties
    • Fuel-efficient engines help manage operating costs over long run times
    • Modern control systems improve monitoring, safety, and ease of use

    Generator Applications

    • Construction and civil works requiring temporary site power
    • Agricultural operations, including irrigation, sheds, and remote infrastructure
    • Backup power for homes, businesses, and critical services
    • Mining, quarrying, and remote camp power supply
    • Events, marine use, and recreational off-grid activities

    Types Of Generators

    • Stationary generators are fixed installations designed for long-term use, often providing backup or primary power for buildings and facilities. They are suited to commercial sites, farms, and industrial operations requiring consistent output.
    • Towable generators are trailer-mounted for easy transport between jobsites. They are commonly used in construction and civil works where temporary power is needed across multiple locations.
    • Portable generators are compact units designed for light-duty tasks and easy handling. They are ideal for trades, small worksites, and emergency backup use.
    • Compact recreational generators are lightweight and quiet, built for camping, caravanning, and leisure activities. They prioritise portability and low noise over high output.
    • PTO generators connect to tractors via power take-off, making them a practical option for farms. They use existing machinery to generate power for rural applications.
    • Power plant generators are large-scale systems designed for high-output, continuous power generation. They are used in industrial settings and major infrastructure projects.
    • Marine generators are built for onboard use in vessels, providing reliable electrical power in offshore conditions. They are designed to withstand moisture, vibration, and salt exposure.
    • Home standby generators automatically supply power during outages. They are suited to residential properties needing uninterrupted electricity for essential systems.

    How To Buy The Right Generator

    • Determine power requirements: Calculate the total load needed to run your equipment or property to ensure the generator can handle peak demand.
    • Choose the right mobility: Portable and towable units suit changing worksites, while stationary models are better for fixed installations.
    • Consider fuel type and runtime: Diesel, petrol, and alternative fuels each affect efficiency, availability, and operating costs.
    • Assess noise and environment: Quieter models are important for residential or urban use, while rugged units suit harsh outdoor conditions.
    • Review maintenance and support: Access to servicing and parts is essential for reliability, especially in remote Australian locations.
