Renting vs Buying Construction Equipment
(Click to Enlarge)

To complete their construction projects, construction companies usually have the option to either rent or buy the necessary equipment. The decision to buy vs. rent construction equipment is important, as it will impact the project’s management, budget, and construction plans. The decision also depends on the complexity and scope of the project itself.

Depending on the company’s short- and long-term construction goals, renting and buying each has its own advantages and disadvantages. This post outlines the benefits of renting equipment and when it’s best to buy. 

Benefits of Renting Construction Equipment

Renting construction equipment has become popular among construction companies. The benefits of renting include: 

Low Upfront Costs

Businesses prefer to rent construction equipment to avoid high upfront costs. Buying tools means they’ll be required to pay more upfront, which affects budgeting, especially if it’s a small company with little capital. 

No Maintenance Costs

Renting equipment ensures companies won’t be responsible for repair or maintenance costs. Renting heavy machinery like trucks and cranes is especially cost-effective because they are only used sparingly in most projects.

Eliminates Unnecessary Purchases

Renting eliminates unnecessary purchases, as a company can conveniently choose what they need depending on each project. For example, a contractor can rent a compact excavator if they are working in small spaces or multiple locations.

No Extra Storage Cost

Storage costs and services for large construction equipment may be too expensive for companies to sustain in the short and long term. Rental options allow you to avoid these extra storage and transportation costs. 

No Long-Term Losses

The value of construction equipment reduces over time, and buying may present a challenge if you decide to cash in later. As long as the construction equipment is used regularly, its worth will depreciate. Rental equipment depreciates, but you won’t incur any loss of value since you’re only renting it. 

Rent-To-Own Construction Equipment

Renting presents an opportunity to try a product before buying it in a rent-to-own agreement. Renting equipment allows companies to observe how viable it is for their projects, test its functionality, and use it as they finance its purchase. Rent-to-own heavy equipment may be preferable to the upfront purchase of equipment due to the flexibility it affords. 

Lowers the Market Entry Barrier

New or small companies in the construction market can still get big projects by renting the equipment they need. Not all companies are eligible for large-scale construction projects because they lack the necessary equipment, and renting provides easy access to all tools. 

Benefits of Buying Construction Equipment

Some construction companies may prefer to own their construction equipment instead of renting. Some of the benefits of buying equipment include:

Long-Term Cost-Effectiveness

Over the long term, buying heavy equipment is more cost-effective than renting, despite the high upfront costs. Renting means a company regularly pays to access its services, and projects may stall if the waiting period to use the tools is long. 

Tax Benefits

Buying presents potential tax benefits that cannot be fully leveraged through renting. Companies can deduct equipment depreciation and loan interest.

Convenience of Ownership

When you own your equipment, you can use, sell, rent, or trade it at any time. While renting presents a flexible option to access equipment, their availability may heavily depend on the demand from other renters. 

Crucial for Large-Scale Projects

Buying equipment ensures businesses are well-positioned for any large-scale projects. Investing in and regularly using large equipment like bulldozers and excavators, as well as specialized equipment, can help companies save on costs throughout these longer-term projects.

When It Makes Sense to Buy Construction Equipment

Renting construction equipment is a viable option for many companies, especially when considering factors like upfront costs, depreciating value, and storage costs. However, there are times when buying equipment would be a better option overall. These include when: 

  • The equipment will be regularly used: If the equipment will be used often, then it’s best to pursue the purchase option. As a general rule of thumb, if the equipment is used more than 65% of the time, you should buy it. For construction excavators, it’s a good idea to purchase one if it will be used more than 175 hours a year.
  • Handling long-term projects: Buying is also a more cost-effective, convenient option if a business is looking at a long-term construction project. Long-term projects require flexibility and consistent utilization of equipment. Renting confines the user and may stall the project, depending on the demand for the rental equipment. 
  • Specialized construction equipment is needed: Specialized equipment may be even less available for rental, causing significant project delays. Buying specialized construction equipment is better than renting especially if they’ll be needed frequently.

Best Practices for Diesel Engine Maintenance

Diesel engines are widely used in automobiles, generators, marine vessels, industrial machinery, and more. They are known for their durability, efficiency, and power. However, like any other type of engine, diesel engines require regular maintenance to ensure optimal performance and longevity. Implement these best practices for diesel fuel system maintenance to prevent breakdowns, reduce repair costs, and extend the engine’s life.

Best Practices for Diesel Engine Maintenance

Monitor the Coolant

Regularly monitoring your diesel engine’s coolant is critical for optimal engine performance. Over time, the coolant becomes more acidic and can corrode other cooling system parts, such as the radiator. Check the coolant’s acidity levels and have it flushed on a regular schedule.

Moreover, make sure the cooling system is adequately filled with coolant and has the appropriate freeze protection level for its operating environment. Failure to do so can cause overheating and corrosion or result in the coolant freezing and expanding, causing passages or lines to crack.

Low coolant levels likely indicate loose or worn hoses or leaking radiator. Sometimes it may be caused by head gasket leakage, which can eventually contaminate the engine oil and cause engine failure. Tier IVF and IVi engines should be checked for nitrogen reduction system (NRS) and exhaust gas recirculation (EGR) cooler leaks. These leaks present as a slow, constant loss of coolant, and if left unchecked, they can damage the diesel particulate filter, intake, and intake valves.

To maintain proper coolant levels and properties, technicians should regularly test the coolant chemistry and follow strict drain and refill intervals. Your coolant supplier can also be a valuable resource for verifying the effectiveness of your chosen preventive maintenance procedures.

Check for Clogged or Dirty Fuel Injectors

Maintaining clean fuel injectors and diesel fuel is crucial to keeping diesel engines running smoothly. Diesel fuel is more viscous than gasoline and can more easily hold dirt and debris in suspension. When injectors are clogged or dirty, the fuel may not spray properly in a fine mist, causing the engine to skip or completely stop.

Here are some signs that your diesel injection systems are dirty or clogged:

  • Black smoke from the exhaust manifold
  • Hard starting
  • Rough idling
  • Pinging sounds
  • Throttle hesitation
  • Increased fuel consumption
  • Poor engine performance

To keep diesel fuel injection systems clean, it’s essential to:

  • Change oil regularly: Oil picks up contaminants from the engine, leading to buildup on the fuel injectors. Regular oil changes remove this buildup and ensure the engine runs smoothly and efficiently.
  • Replace Fuel Filters when needed.
  • Use high-quality additives: To protect parts and maintain their cleanliness, use high-quality additives specifically designed for this purpose. For recommendations on the appropriate additives for your machine, refer to the manual or the manufacturer of your diesel engine.

If the engine exhibits irregular running, rapping, or black smoke, the spray nozzle valves may be clogged or held open due to dirt particles. This can cause inefficient fuel combustion, leading to poor performance and black smoke.

Clean Filters

Diesel engines commonly have two fuel filters: A primary filter between the fuel tank and engine and a secondary filter between the fuel injectors and transfer pump. Diesel fuel, being less refined, absorbs the extra water from condensation in the tank. Water in the fuel can cause several problems, including reduced fuel efficiency and engine stalling. This is why manufacturers build diesel engines with two fuel filters and sometimes three.

Regularly changing air filters also ensures your engine runs smoothly. The air filter is usually inside a rectangular cold air box near the front of the engine compartment. A clogged air filter can restrict the engine’s intake, requiring it to use more fuel to generate the same power or acceleration. Typically, an air filter should be replaced every 12,000 miles or more often if you notice issues like weaker acceleration or reduced engine power.

Diesel Engines 101

Click to ExpandDiesel Engines

Diesel engines are internal combustion engines that operate on the principle of compression ignition. Unlike gasoline engines, which rely on spark plugs for ignition, diesel engines use the heat generated by compressing air to ignite the fuel. They are known for their efficiency, durability, and high torque output, making them popular in various applications.

In this guide, we will take a closer look into the inner workings of diesel engines, uncovering their advantages and impact on various industries.

The Components of a Diesel Engine

To understand how diesel engines work, it is helpful to break down their key components:

  • Cylinder block and pistons: The cylinder block houses the cylinders where combustion occurs. The pistons move up and down within these cylinders, compressing air and fuel and driving the crankshaft during the power stroke.
  • Fuel injection system: Diesel engines use a fuel injection system to deliver precise amounts of diesel fuel into the combustion chamber at the right moment.
  • Turbocharger: Many diesel engines are equipped with a turbocharger. It uses exhaust gases to spin a turbine that compresses incoming air before it enters the combustion chamber. This allows for more efficient combustion and increased power output.
  • Cooling system: Diesel engines generate significant heat during operation, so an effective cooling system is essential to prevent overheating and maintain optimal performance.

Benefits of Diesel Engines

Diesel engines offer several advantages over their gasoline counterparts, making them a preferred choice for various applications. Here are some of its key benefits:

Fuel Efficiency

Diesel engines are known for their superior fuel efficiency compared to gasoline engines. They typically consume less fuel to produce the same amount of power due to their higher compression ratios and better thermal efficiency. This results in lower fuel costs, especially in vehicles and equipment with high fuel consumption rates, such as trucks and heavy machinery.

Durability and Longevity

This engine type is renowned for its robust construction and longevity. It is built to withstand higher stress levels and compression, making it more durable and reliable over extended periods of use. This translates to lower maintenance costs and longer service intervals, contributing to overall cost savings.


Diesel engines produce more power per unit of displacement compared to gasoline engines. They can achieve higher power outputs with smaller engine sizes, resulting in more compact and lightweight designs without compromising performance. This is particularly advantageous in applications with limited space and weight, such as marine vessels and heavy machinery.

Low Carbon Dioxide Emissions

These engines emit less carbon dioxide (CO2) per mile due to their superior fuel efficiency. This makes them a more environmentally friendly option regarding greenhouse gas emissions, especially in vehicles that cover long distances or operate for extended periods.

Adaptability and Versatility

Various fuels are compatible with diesel engines, including biodiesel and synthetic diesel blends. They can also use renewable diesel from vegetable oils, animal fats, and waste materials. This allows for greater flexibility in fuel sourcing and promotes sustainability by reducing reliance on fossil fuels.

Reliability in Extreme Conditions

Diesel engines are well-suited for operation in extreme weather conditions, including cold temperatures, high altitudes, and rugged terrain. They offer better cold-start performance and maintain consistent power output even under challenging circumstances.

Diesel vs. Gas Engine: Life Expectancy, Emissions, Efficiency


When comparing diesel and gasoline engines, diesel engines are ultimately considered superior to gas engines in heavy-duty vehicles because of their improved fuel efficiency and longer life expectancy. They are often the preferred engine type for vehicles such as emergency vehicles, bulldozers, dump trucks, excavators, ships, semi-trucks, and trains.

Diesel vs Gas Engine

Diesel vs Gas: Understanding the Differences

Though both diesel and gas engines are internal combustion engines, there are differences in their operations that make diesel engines more suitable for industrial vehicles. The differences come from:

  • The higher energy density of diesel fuel
  • The greater compression of air by diesel engines
  • The absence of spark plugs in diesel engines


These differences contribute to the following characteristics:

  • Life expectancy. Diesel engines compress air almost twice as much as gas engines (approximately 20:1 vs 10:1). As such, engine parts like block and cylinder heads, crankshafts, pistons, and valves in diesel engines are designed to be more robust than gas engines. This higher compression also results in more complete combustion of the fuel than what is found in gas engines, so diesel engine exhaust is less corrosive. This contributes to a longer service life for engine components.


  • Fuel costs and efficiency. Due to increased air compression, diesel engines also operate at higher temperatures than gasoline engines. This results in a more efficient conversion of thermal energy to mechanical energy. Diesel engines are about 15–40% more efficient than gas engines and diesel fuel is about 15% cheaper than gasoline. Therefore, the per-mile cost of diesel engines is significantly lower than gas engines.


  • Torque/horsepower. The high compression ratio of diesel engines gives them an ability to create a higher torque at lower engine speeds. Also, diesel fuel has 12–16% more energy content than gasoline. These factors make diesel engines ideal for heavy load applications that require a steady, high torque.


  • Maintenance costs. Diesel engines do not have spark plugs. Diesel is also a much better lubricant than gasoline. When considering emissions from diesel versus gasoline, the more complete ignition of the diesel fuel produces less pollutants and corrosive agents. Diesel engines operate at a lower rpm than gas engines. All these factors contribute to reducing the maintenance costs for diesel engines.

The Importance of Proper Engine Maintenance

Diesel fuel easily picks up contaminants due to its high viscosity. Periodically changing the oil and oil filter will clean accumulated dirt from inside the engine. It is also important to keep an eye on oil consumption as an early indicator of harmful oil leaks. These should be quickly detected and promptly fixed.

Diesel engines require a steady supply of clean air to maintain peak performance. Dirty filters reduce airflow to the engine, so it is important to regularly inspect and change air filters. This is especially important for dump trucks, military vehicles, and boats that operate in harsh environments.

Over the course of June – National Safety Month – the National Safety Council raised awareness of the most common causes of injury and death in the workplace and helped companies develop effective strategies to ensure the safety and health of their workers. As a proud supporter of National Safety Month, we wanted to take a moment to further that mission by sharing some of our safety solutions with our customers.

How Can You Improve Workplace Safety?

Workplace safety should be a leading priority for any company, but it doesn’t need to be a challenge. Taking these simple steps can help you keep your workplace is as safe as possible at all times.

1. Follow OSHA Guidelines 

The Occupational Safety and Hazard Administration (OSHA) was founded to protect American workers from harmful conditions by establishing safety standards for every major industry and educating businesses on the best practices for their workplaces. Regardless of your field, be sure to acquaint yourself with any relevant OSHA regulations and follow them as closely as possible.

2. Post Signs, Labels, and Warnings throughout the Workplace

Workplace accidents are usually the product of carelessness or ignorance rather than deliberately unsafe behavior. Outlining the precautions that employees need to take before entering a certain space or handling a particular piece of equipment can significantly reduce the risk of injury or death on the job.

3. Employee Training and Certification Programs

At the end of the day, the best safeguard against occupational hazards is a well-informed staff. All employees should receive thorough instruction in any tasks or processes in which they’re involved, and any functions that could endanger the entire workplace if performed improperly should be limited to employees with special certifications.

Recognizing Industry Contributions for National Manufacturing Day 2017

Even though experts believe that two decades of policy failures have stagnated the growth of the US manufacturing sector, it is still active enough to employ 8.8% of the national workforce and taken alone would be the ninth largest economy in the world. But if the golden era of manufacturing is to return to the shores of the country in earnest, a lot more than just infrastructural expansion and demand generation would have to be taken into account.

While the next eight years will see about three and a half million new jobs added to the sector, sadly two million of these vacancies will go unfilled.

There is hope for the future but to usher it in the United States needs more students interested in S.T.E.M careers, better knowledge transfer between employees, and a revamped perception of what careers in manufacturing are like in 2017.

The National Manufacturing Day (NMD) – a nation-wide endeavor undertaken the first Friday of every October attempts to hit the goals above.

Annually celebrated on the 6th of October, we’re taking a look at the impact of NMD and the contribution of our industry to manufacturing as a whole.

What Has the National Manufacturing Day Achieved?

Over the last six years, the National Manufacturing Day has seen the participation of hundreds of thousands of suppliers, manufacturers, and students. More than 2,100 factory tours have been organized, and in 2017 it is expected that 600,000 businesses and individuals will be associated with the event.

Thanks to the impact of NMD and a closer look at the changing face of American manufacturing careers, 81% students are more convinced that manufacturing can provide them with stable, interesting and well-paying jobs.

89% are also more aware of manufacturing opportunities in their communities, and 64% are more likely to pursue them.

Diesel Engines: Igniting the Manufacturing Spark

Almost all industries that are a part of the manufacturing sector look back at what businesses have achieved over the years when the National Manufacturing Day rolls around.

The diesel engine market is billions of dollars strong in the US, heavily contributing to both the manufacturing sector and the economy. With the Diesel Emissions Reduction Act, this number is only going to increase.

Moreover, without diesel engines, all aspects of manufacturing from the actual production of goods to their transportation suffer because other combustion set-ups consume more fuel, produce lower torque and are far less durable and resilient than their diesel peers.

Diesel engines save the manufacturing sector millions every year in maintenance and repairs.
