Engine-Driven Power Units: Versatile Solutions for Remote Work Sites

Engine-driven hydraulic power units provide a versatile, portable, and powerful solution for generating hydraulic power in a variety of settings. Their independence from electrical power sources, high power output, ease of refuelling, and robust performance make them an invaluable asset across numerous industries and applications.

Benefits of Engine Driven Hydraulic Power Units?

Engine-driven hydraulic power units (HPUs), whether powered by petrol or diesel engines, offer a range of benefits that make them suitable for various applications where hydraulic power is needed. Here are the key advantages:

1. Portability

  • Mobility: Engine-driven HPUs are highly portable, making them ideal for use in remote locations or job sites where electrical power is unavailable. Their self-contained nature allows them to be easily moved and deployed wherever needed.

2. Independence from Electrical Power

  • Versatility: These units can operate independently of an electrical power source, which is particularly useful in areas without reliable electricity or during power outages.
  • Flexibility: They can be used in a wide range of environments, including construction sites, agricultural fields, and disaster response scenarios.

3. High Power Output

  • Efficiency: Engine-driven HPUs can provide a high power-to-weight ratio, delivering significant hydraulic power output relative to their size and weight.
  • Performance: They are capable of driving high-pressure hydraulic systems, making them suitable for demanding applications.

4. Ease of Refuelling

  • Convenience: Refuelling an engine-driven HPU is typically straightforward and quick compared to recharging batteries or finding a suitable electrical outlet.
  • Availability: Both petrol and diesel fuel is widely available, ensuring that the units can be refuelled in most locations without difficulty.

5. Robustness and Reliability

  • Durability: Engine-driven HPUs are known for their robustness and ability to withstand harsh operating conditions. They are designed to handle rough use and can perform reliably in various environments.
  • Maintenance: These engines are generally easier to maintain and repair compared to more complex power sources, such as electric motors.

6. Cost-Effectiveness

  • Initial Investment: Petrol and diesel engine-driven HPUs often have a lower initial cost compared to other types of power units.
  • Operating Costs: While fuel costs can vary, the overall operational costs can be lower due to the engine’s efficiency and ease of maintenance.

7. Application Versatility

  • Wide Range of Uses: These units are suitable for diverse applications, including construction, mining, agriculture, forestry, and emergency services. They can power various hydraulic tools and equipment, such as jacks, pumps, and drills.

8. Environmental Adaptability

  • Performance in Extreme Conditions: Engine-driven HPUs can perform well in both cold and hot environments, making them adaptable to different climatic conditions.

9. Extended Operational Range

  • Longer Runtime: Compared to battery-powered units, engine-driven HPUs can run for extended periods without needing to stop for recharging, as long as fuel is available.

10. High Efficiency

  • Fuel Efficiency: Modern engines are designed to be fuel-efficient, providing a cost-effective solution for long-term use in various industrial applications.

What Engine Driven Power Unit is right or me?

  • Pump Sets - An engine pump set is a self-contained unit that consists of an engine (usually petrol or diesel) coupled with a pump. This combination provides a portable and independent source of power for pumping fluids, making it useful in various applications where electric power is unavailable or impractical.

  • HI/LO Gear Pump Set - A HI/LO gear pump set is a type of hydraulic pump system that features two distinct gear pumps—one designed for high-flow, low-pressure operation (HI) and the other for low-flow, high-pressure operation (LO). This configuration allows for efficient operation across a wide range of pressures and flow rates, making it particularly useful in applications requiring both fast actuation and high-force exertion, whilst keeping the size of the engine required to a minimum at the same time.

  • H Frame Skid Units - An H Frame Skid Engine Unit is a type of portable hydraulic power unit designed for rugged and flexible use, often in industrial, construction, and agricultural settings. The "H frame" refers to the structural design, which resembles the shape of the letter "H," providing stability and protection for the components. The "skid" aspect means that the unit is mounted on a skid frame, making it easier to transport and deploy in various locations.

  • Portable Power Unit - A portable power-driven unit on wheels is a compact, mobile device that provides power to operate various tools and machinery in remote or on-site locations. These units are designed to be easily transported and used in environments where stationary power sources, such as electricity, are unavailable or impractical.

What Engine is right for me Honda or Loncin?

Choosing between a Honda and Loncin engine for your needs depends on several factors, budget, performance, availability, and specific application requirements. Here’s a detailed comparison to help you decide which engine might be right for you:

Honda Engines:

Reliability and Durability:

  • Honda engines are known for their exceptional reliability and long lifespan. They are built with high-quality materials and rigorous manufacturing standards.


  • Honda engines are generally more efficient and provide consistent performance across various applications.
  • They are known for easy starting and smooth operation.

Brand Reputation:

  • Honda has a long-standing reputation for quality and innovation in the engine and power equipment industry.
  • Strong customer support and widespread availability of parts and service centres.

Resale Value:

  • Honda engines tend to have higher resale value due to their reliability and brand reputation.
  • Higher initial investment might be a consideration for budget-conscious buyers.


  • While generally available, there might be regional variations in availability and lead times.

Loncin Engines:


  • Loncin engines are more budget-friendly, offering a lower initial cost compared to Honda engines.
  • They provide good value for money, especially for applications where cost is a critical factor.


  • Loncin engines offer reliable performance suitable for many applications.
  • They have improved significantly in quality and reliability since marketing their engines in 1998.


  • Widely available and often come with competitive warranties.
  • Parts are generally accessible and more affordable.
  • Loncin brand has partnerships with large corporations for example Loncin produces units in partnership with Japan’s Honda & BMW since 2005.

Decision Factors:


  • If the engine is for professional or heavy-duty use where reliability and performance are paramount (e.g., commercial construction, industrial applications), Loncin is still a perfect choice.


  • If budget is a major concern, Loncin engines provide a more affordable option with great performance.

Maintenance and Support:

  • Consider the availability of parts and service centers in your area. Honda typically has a more extensive network.
  • Loncin parts are also available but might require more effort to source in some regions.


  • Choose Honda if you need a highly reliable, durable, and efficient engine with strong brand support and are willing to invest more upfront.
  • Choose Loncin if you are looking for a more budget-friendly option with great performance for less this is a perfect choice.

What are the differences between petrol and diesel engine-driven power units?

Petrol engines are generally lighter, quieter, and cheaper upfront but may have higher fuel consumption. Diesel engines are more fuel-efficient, durable, and provide higher torque, making them better for heavy-duty applications.

What are the primary uses of engine-driven power units?

They are used in construction, agriculture, emergency services, industrial maintenance, mining, and remote operations for powering hydraulic tools, pumps, generators, and other equipment.

Can engine-driven power units be used indoors?

While engine-driven power units can be used indoors, doing so safely requires careful planning, adequate ventilation, strict adherence to safety protocols, and regulatory compliance. Consider alternative power sources for indoor use to eliminate risks associated with combustion engines. If using an engine-driven unit indoors is necessary, implementing robust safety measures and monitoring systems is crucial to protect the health and safety of personnel.
