When your facility requires a reliable emergency power supply, choosing the right backup power generator configuration impacts everything from installation costs to long-term operational flexibility. At Hosem Power Co., Ltd., we manufacture both trailer mounted and skid mounted types of diesel generators to meet global industrial standards. This guide will help you decide which one fits your specific needs.

1. Skid Mounted Diesel Generator: The Power of Permanence

A skid mounted diesel generator is built on a heavy-duty steel base frame. These generators need to be installed on a flat, solid surface for use to keep them stable. Best For:

    • Static Facilities: Factories, hospitals, and high-rise buildings.

    • Continuous Operations: When you need a steady emergency power supply in a single location.

    • Large Scale Power: Most generators over 1000kVA are skid-mounted due to their immense weight.

Key Advantages:

    • Cost Efficiency: Without the cost of axles and tires, a skid mounted diesel generator is more budget-friendly for fixed sites.

    • Reduced Vibration: When bolted to a reinforced foundation, these units provide the most stable backup power generator solution.

    • Seamless Integration: Easily connects to your building’s Automatic Transfer Switch (ATS) and large external fuel systems.

2. Trailer Mounted Generator: Ultimate Mobility

A trailer mounted generator is a complete power station on wheels. These generators are housed in weatherproof, soundproof canopies and mounted on custom-engineered trailers. Best For:

    • Construction & Mining: Sites where the power source must move as work progresses.

    • Rental Businesses: Companies providing temporary emergency power supply for events or roadwork.

    • Utility Repair: Quick deployment of a backup power generator during unplanned grid outages.

Key Advantages:

    • Zero Site Prep: No need to pour concrete. Simply tow the trailer mounted generator to the site and start the engine.

    • Rapid Deployment: Can be transported at highway speeds to provide an immediate emergency power supply anywhere.

    • High Resale Value: Because they are easy to transport, mobile units often have a better secondary market value.

4. Quality Standards Across All Models

Regardless of the mounting type, the performance of your backup power generator depends on its core components. At Hosem Power, we ensure every unit meets the following:

    • Premium Engines: We use world-class brands like Perkins, Cummins, Baudouin, and Weichai to power both our mobile and fixed units.

    • Certified Quality: All our industrial generators are CE and ISO 9001 certified.

    • Weather Protection: Our trailer mounted generator units and skid-mounted silent types feature high quality spraying powdered material for harsh environments.
