Access to dependable or permanent power sources is often lacking on construction sites. This is particularly true in isolated areas or in the early phases of area development. Generators are helpful in this situation. They supply the short-term electricity required to run tools, machinery, lighting, and other crucial site equipment.

However, selecting the right generator for your construction site is crucial. Otherwise, your equipment might not have enough power to run effectively. This could cause delays, damage to your tools, or even safety risks.

Keep the following factors in mind when selecting the best construction site generator at Ablesales:

Your equipment needs

First and foremost, list all the equipment you need to use on the construction site. Then, note their power requirements. You can find this wattage information on the labels or in the equipment manuals.

The following are some examples of construction equipment and their typical wattages:

  • Concrete mixers: 500–2000 watts
  • Air compressors: 1000–4,000 watts
  • Power drills: 450–1500 watts
  • Welders: 4000–9000 watts
  • Round saws: 800–2500 watts
  • Each floodlight uses 500–1000 watts

These tools will not work correctly if the generator cannot supply the site’s power needs.

The amount of power required

The maximum output and rating of the generator you select must be sufficient to satisfy the needs of your job site. Maximum output is the power a generator can produce, even if it is just momentarily. Rated output is the amount of power a generator can produce continually.

You must ascertain the total wattage of all the construction equipment you plan to load onto the generator set. In other words, calculate the power needed for each piece of equipment, both to start it and to keep it running. This will help you to calculate the rated and maximum output you will need from your generator.

Regarding your needs, a mobile generator’s rated output is the total running power for all of your tools. The maximum output you’ll need is the sum of the beginning power for each of your power tools.

As a precaution, take those figures and add a 10% buffer. For instance, it may take twice as many watts to start an air compressor as it does to run. Say 3000 watts to start but only 1500 to run. If you select a generator set that isn’t suitable for its intended use, it won’t power your site sufficiently. It will also break down quickly.

The various types of generators available

Different kinds of generators are available. Each has unique features and advantages. However, the ideal generator for your construction sites is the one that will meet all of your power needs without any issues.

High, medium, standby and portable generators are the four models most frequently found on building sites. Let’s examine these a bit more closely…

Portable generators

These are the most widely used kinds on building sites. You can move them to different parts of the site to power various tools and equipment, including heavy-duty machinery.

High-powered generators

These are suitable for large construction sites or projects that need a lot of energy to run heavy machinery and tools simultaneously. This could include tools for laying roads and earthmoving equipment. These generators can also power material handling machines.

Medium power range generators

These typically range from 5,000-20,000 watts. They work well on moderate-sized construction projects.

Standby generators

These serve as a fallback power supply if the main one fails.

Fuel types

Considering several fuel types when purchasing a generator for a building site is crucial. This will help you improve fuel efficiency and reduce operational expenses. Diesel, gasoline, and LPG are the three most popular fuel sources used in generators.

Generators that run on diesel

Diesel generators have a strong power output. They are perfect for powering large machinery and numerous tools at once on a building site. They are made to endure harsh conditions and constant use, which is extremely typical on building sites.

Generators powered by petrol

Petrol generators are lighter and easier to move about. They are ideal for smaller mobile applications on a building site. They are also frequently less costly than diesel generators. However, they are generally less durable. They also have a poorer fuel economy.

Generators that use LPG (liquefied petroleum gas)

This is ideal for locations with strict environmental requirements. Why is this so? Because it generates fewer pollutants and greenhouse gases. Therefore, it burns cleaner than gasoline and diesel generators.

Additionally, LPG generators run more silently than diesel generators. This is advantageous in locations where noise levels must be kept to a minimum, particularly in residential or noise-sensitive areas.

Quietness and environmental impact

The industry guideline for a generator’s sound level at 23 feet is roughly 70 dB(A). The majority of generators satisfy this requirement. However, you may need a generator with greater sound attenuation (reduction) based on the location or use of your job site.

Your generator set will cost more if you need greater sound attenuation. Your supplier can assist you in determining how much attenuation you need.

Additionally, consider the generator’s effects on the environment. This includes emissions and fuel economy. Choose a brand that prioritizes fuel-efficient technologies and adheres to environmental rules to lessen your carbon footprint.

Portability and storage

Lightweight portable generators with integrated handles or wheels make for convenient transportation. Make sure there is enough room to store the generator while not in use. It should be a dry, well-ventilated place, away from combustible objects.

Runtime

The term “runtime” describes how long your generator will operate before needing to be refueled. A generator should generally be able to meet the load requirements of your job site at 100% for the duration of a normal workday. Everything more than that is extra. Anything less will result in you losing valuable work time while your team waits for the generator to be refueled.

Conclusion

Choosing the right construction site generator is crucial for avoiding downtime and expensive errors, regardless of the scale of the project.
