What is a compactor and how to choose the right one?

Did you know that the total amount of municipal solid waste in 2017 was 267.8 million tons? Are you looking to reduce the waste generated by your company?

In this article, you will learn what a compactor is. You will also learn how to choose the right one. Keep reading to learn why owning one is so important for your business and how it can be so beneficial.

What is a compactor?

A commercial, construction or industrial compactor is a machine that collects waste into a container. The operator first places the waste from a loading dock into a chute on the machine on the ground. The waste accumulates inside the container until the operator performs a compaction cycle.

The compaction cycle is the process where a platen connected to a hydraulic ram pushes the waste into one end of the container. This waste is then crushed and reduced in size.

You can also choose from road compactors, soil compactors, and earthwork compactors. Soil compactors are popular in industrial construction areas.

Soil Compactors

Soil has four components: granular rock, minerals, air, and water. Soil compactors increase density and remove air pockets by kneading, vibrating, or compressing the soil. It is vital to use soil compactors correctly because they can cause serious or fatal injuries. Always make sure you use the correct operating instructions and receive practical training for the soil compactor you use.

Before using a soil compactor, make sure you follow the manufacturer's maintenance schedule and inspect the equipment. Always use guards on pinch points and moving parts. Have a backup alarm so pedestrians know the roller is moving.

If you don't use soil compactors, you may experience pipe leaks, ruptures, slab cracks, and foundation erosion. If you use a soil compactor for a long time, you are more likely to suffer from vibration syndrome. This can cause damage to the nerves and circulation in the fingers.

Symptoms of this condition include whitening, pain, and numbness. Read the instructions for vibration level ratings and maximum usage. Always keep your back straight and your posture correct when using a soil compactor.

Road Roller

Road roller, also known as road roller, is used to compact asphalt, concrete, gravel or soil. It is used in the construction of foundations and roads.

Pneumatic Roller

Pneumatic rollers have rubber tires. They are used to compact coarse-grained soils, such as in roadbed pavement projects. The roller uses the weight of the vehicle to compress the surface. The flexibility of the pneumatic straps allows the roller to work on uneven ground.

Vibratory Plate Compactor

It is used to compact different types of gravel and soil. They use a thick steel plate at the bottom, similar to a lawn mower.

Plate Compactor

Plate compactors are best used to create level slopes. Jump jack compactors have smaller feet. Jack compactors are mainly used to compact backfill soil inside gas supply pipes or water supply ditches.

Why Buying Used Rental Equipment is a Good Move？

Purchasing used rental machinery can be a beneficial decision for your company when you find that your rental equipment is being used more than you expected. Rather than continuing to rent equipment that you use every day, you can save money by choosing to invest in owning the equipment. There are even more advantages to buying rental equipment that your company should consider to ensure that you are set up for future success.

Learn more about why buying previously rented construction equipment is a good idea, and the benefits you can gain from buying reliable used equipment.

  -------------------------------------------------------------------------------------------

When should you buy used rental equipment?

It is normal to rent equipment when a company does not plan to use the machine more than 40% of the time. The basic idea is that if your company does not use the equipment often, it does not make sense to make a large purchase and incur the long-term payments and costs associated with owning the machine. In situations where you do not use the equipment often, the short-term commitment and lower costs offered by rental equipment make it a more attractive option.

Sometimes companies start renting equipment because they do not know how often they will use it, or if their future projects will rely on the equipment. Over time, they may find that they use the rental equipment much more than they initially expected. If the equipment is being used at more than 40% and the company expects to continue using it regularly, it is usually time to purchase used rental equipment.

Why is buying a used rental machine a good idea?

If you are wondering if you can buy a used skid steer for rent, the answer is probably yes. Rental equipment, from skid steers to excavators, can be an excellent investment for your company. Buying a rental has many advantages, such as saving on purchase costs and giving you the peace of mind that you are purchasing high-quality equipment. You can also benefit from the operator's familiarity with the machine, a wide range of equipment to choose from, and maintenance history.

Learn more about the many advantages you can gain from buying rental equipment:

1. Savings

If you use your rental equipment more than 40% of the time, you may want to consider switching from leasing to buying. Over time, you may notice that you rely on your rental equipment more than you planned. It is important to remember that the longer you rent, the more you pay in total expenses. Over time, you may end up paying more in rentals than if you had purchased the equipment earlier.

By buying the equipment, you can recoup your money over the long term and sell the equipment once you are ready to upgrade or replace it. Instead of incurring expenses in the form of rental costs, you will acquire an asset that you can resell or customize at your leisure.

In addition to the money you can save by buying, you can also save on the cost of buying by using a previous rental. Since rental companies tend to buy equipment wholesale from manufacturers, you can often get some great deals on used construction equipment. By buying wholesale, they will often purchase equipment at below market value. These cost savings can be passed on to customers, helping you find quality used construction equipment at a lower cost.

2. No Guesswork on Quality

There is another great advantage to buying rental equipment that you have previously used on a job site as a rental. Since you have used the equipment in the past, you will know its quality and the performance it regularly delivers. Even if you haven’t used the equipment directly, a reliable rental equipment dealer will perform all the necessary maintenance on the equipment to ensure it is still operating at a high level at the point of sale.

It is also common practice for rental companies to retire machines while they are still young. This practice of early retirement means that you can still get fairly new equipment that has been well cared for during its use. If you wish, you can also find equipment with advanced technology and features that can increase the efficiency and productivity of the machine.

3. Wide Selection of Rental Equipment

Part of the appeal of a rental company is the large selection of equipment that its customers can choose from. Just like a wide variety of rentals, you can also expect to receive a similarly sized inventory that you can choose from when you purchase. The wide selection you receive when purchasing rental equipment means that you can find a machine that fits your company's needs and the type of work you plan to use it for.

4. Service and Repair History

Rental companies want their equipment to run optimally. Their customers rely on high-quality equipment that delivers on its promises and is reliable. Rental companies that fail to provide equipment that meets these expectations are doomed to fail.

Since rental companies need to provide their customers with well-maintained and high-performing equipment, reputable dealers have a long history of preparing and servicing their equipment. The benefit of buying a piece of rental equipment is that it increases the likelihood that the machine has been properly maintained. In addition, a good dealer will provide you with service records as proof of regular inspections, oil changes, hours of use, and any other repairs.

5. More Familiarity with the Machinery

When you purchase rental equipment that your company already uses, your operators will already know how to use the machine. This familiarity with the equipment saves time because you don't have to schedule training for your operators on how to use it. As a result, you can deploy the equipment to the job site immediately.

Things to Consider When Purchasing Previously Leased Equipment

When you purchase used equipment for your business, you want to choose a machine that you can use for a long time. The following tips can help you determine if a previously leased machine is worth the investment.

Choose a Trustworthy Seller

When purchasing used leased equipment, it is vital to go to a reputable dealer or rental equipment company. A reliable dealer can help you avoid the risk of accidentally purchasing damaged equipment. They can also give you recommendations on the right machine for you.

Reading testimonials is a good way to gauge if a seller is reliable. Try to find information about past customers and their experiences, if any. Consider what industries the rental company has experience in to determine if they are familiar with your specific needs.

Check the History of the Equipment

Investigating the past of a machine can reveal if the purchase is worth the money. First, make sure it is not a stolen device by taking the PIN and product ID number to your local police station. You can also use online services such as the National Equipment Registry.

If there are any liens against the equipment, you may run into ownership issues. You can check if the machine has an active lien by looking up a financing statement from the Uniform Commercial Code. Equipment may have a history of liens, but you want to be careful of any that are currently active.

Make sure the equipment has not been seized – Equipment is often seized because the buyer cannot pay in full, which can also be a sign that they have not properly maintained the machine.

You should also ask about the machine’s maintenance history. A well-maintained used machine may provide higher performance than a poorly maintained machine, even if it has been documented for longer. 

Perform an on-site inspection

It is crucial to thoroughly inspect used equipment before purchasing to ensure you know what you are buying.

Make sure the condition of the equipment matches the description in the sales listing. If you notice signs of wear and tear that the seller does not mention in the listing, skip the purchase. Minor wear and tear itself is not a problem, but discrepancies may indicate that the seller is not trustworthy, which can lead to further trouble.

Be sure to check the following systems and components for damage, unusual wear, or contamination:

·Hydraulic hoses

·Tracks or tires

·Fluid levels

·Air filters

·Engine filters

·Undercar gear

·Brakes

If you can, take the equipment for a test drive. Doing so will give you the best idea of ​​how it will operate on your site. Check that the engine runs smoothly, with no unusual noises or exhaust, and make sure the machine starts and stops as expected.

If you are unsure of your ability to judge the condition of the equipment, take a trusted technician or other expert with you. They can help you determine if it is good used construction equipment or if you should explore other options.

If you have already rented the equipment yourself, you are already familiar with it. Before deciding to buy the machine you rent, discuss its condition with any workers who operate it. If they report any problems, consider testing and buying other equipment that you have previously rented.

14 tips for small excavator maintenance 

14 Tips for Mini Excavator Maintenance 

Mini excavators, also known as compact excavators, perform a variety of jobs on a job site. Contractors use mini excavators to dig, drill, and move materials in a variety of applications. The compact size and flexibility of these excavators make them ideal for a variety of industries, including construction, demolition, and agriculture. 

You need your construction equipment to work at its best. Although mini excavators are known for their ruggedness, these machines still require daily attention to operate as required. Regular maintenance helps keep your mini excavator in top shape so you can focus on getting the job done. This mini excavator maintenance guide offers some helpful tips to keep your fleet working properly. 

14 Tips for Mini Excavator Maintenance 

Although mini excavators come in different sizes and styles, following some common maintenance steps can ensure your machine is operating at its highest level. Consider these 14 mini excavator maintenance tips to help keep every component of your equipment in good working order: 

1. Train Your Operators Effectively 

Implementing an effective preventive maintenance program starts with effectively training your machine operators. Only if they are trained under normal operating conditions can your mini excavator operators spot potential problems with the machine. 

Training heavy equipment operators on maintenance procedures is essential. Operators should be able to identify engine and exhaust problems, loose bolts, worn belts, missing parts, and filters that need to be replaced. Taking the time to train workers and ensure they can identify the thousands of parts in a mini excavator can save expensive repairs in the future. 

2. Follow a Routine Maintenance Schedule 

After a compact excavator, a maintenance schedule simplifies the maintenance process and ensures workers understand the condition of their machine. To create a maintenance schedule, check your mini excavator maintenance manual. The maintenance manual includes service recommendations on how often to check everything from fluid levels to track tension. 

Regular maintenance should include frequent inspections and longer intervals of maintenance: 

Daily: Operators should check fluid levels, check connections, and ensure attachments are well lubricated every day. 

Weekly: Operators should lubricate the mini excavator's slewing bearing and check track tension and drive belts every week. 

Every Six Months: At six months old, it's a good idea to have a professional come take a look at your mini excavator. Have a certified technician perform preventive maintenance regularly to ensure that no problems go unnoticed. 

Every two years: More time-consuming maintenance should be performed at longer intervals. For example, you should clean your fuel injectors every two years. 

3. Inspect the hydraulic cylinders 

A daily walk-through before operation is one of the most effective ways to maintain your mini excavator and prevent accidents on the jobsite. Taking the time to walk through your equipment and inspect it before each use reduces the chances that you will miss a loose bolt or worn connection. 

The first step in your walk-through should be to inspect the hydraulic cylinders. The hydraulic system is essential to the use of your mini excavator's attachments, so the system should always be working properly. Walk the hydraulic cylinders and inspect the piston rods and seals. Inspect the connecting rods to ensure there are no signs of damage or excessive wear. 

4. Check the attachments 

The next step in your excavator tour is to inspect the attachments themselves. Checking the attachments and couplers for signs of disrepair can help prevent accidents and ultimately reduce your mini excavator's maintenance costs. If there is any rust or other damage to the attachment or arm, replace the parts to relieve any stress on the mini excavator's arm. 

5. Open the side covers 

Walk up to the side covers and open it to inspect what's inside. Check the hydraulic tank, tubes, hoses, and plugs. Look for leaks and breakages. Then check the hydraulic fittings and connection fittings. If there are signs of leaks, correct the problem. 

6. Check the oil-water separator 

Check the oil-water separator to see if there is any water in your mini excavator's fuel. Depending on your mini excavator model, your machine may have an oil-water separator that features a clear bowl with a red ring. If the ring floats, there is water in the fuel. Completing this maintenance step can uncover potentially damaging leaks in the fuel filter. 

7. Check the cooling system 

While you're inspecting the inside of the side covers, check the cooling system. Look for leaks in the system, faulty hoses, and any accumulated trash and debris. If debris is present, clear it and repair the leak. Then check the coolant level. Always make sure the coolant is at the manufacturer's recommended level. 

8. Grease Pivot Points 

Lubricating the pivot points of your mini excavator is one of the most cost-effective maintenance tips you can implement. Daily lubrication of the arm, bucket, and other pivot points ensures that your mini excavator operates properly. Daily lubrication also prevents premature wear of the pins. 

9. Check the Engine Compartment 

After checking everything in the side hood and lubricating the pivot points, move to the engine compartment and lift the hood. First, inspect and clear any debris inside. Then check the oil cap and tighten it if needed. Check all belts for engine accessories. Replace any belts that are worn, frayed, or broken. 

10. Check the Fuel Level 

The next step in the maintenance checklist is to check the fuel level. The engine and hydraulic oil should always be at the recommended level. Operating a mini excavator with insufficient fuel can result in costly losses, so this stage is crucial. Check the maintenance manual for the manufacturer's recommended fuel level. Then check the oil level and change the oil if needed. 

11. Check the Air Filter 

Changing the air filter should be on a regular maintenance schedule, but operators may only need to check it once a week. If you work on a dusty job site, you should check the air filter more often. If the air filter is clogged with dust, you can remove it and gently tap it off to remove excess debris. 

12. Check the Tracks 

Walk around the mini excavator and inspect the tracks for rocks and damage. Clear away debris and replace tracks that are excessively worn. It is also important to look for adequate track tension and adjust it if necessary. If the mini excavator is frequently used on rough terrain, the operator may need to check the track tension daily. This step ensures that the tracks are neither too loose nor too tight, which can cause excessive wear and downtime. 

13. Inspect the Cabin 

After completing the walk-around, inspect the mini excavator cab. This phase of maintenance helps ensure the safety of the operator as well as the safety of others on the job site. Perform all of these steps while inspecting the excavator cab: 

Inspect the falling object protection structure and tighten any loose bolts. 

Remove any accumulated debris from under the floor and inside the cabin. 

Inspect switches or controls for damage and replace if necessary. 

Make sure the mirrors are clean and free of cracks. 

If your mini excavator has an enclosed cab, inspect and clean the windows. 

14. Use Telematics 

One of the best ways to maintain your mini excavator is to use telematics. This technology monitors machine activity and performance to alert the operator when repairs or replacements are needed. Telematics systems also record maintenance history so the operator can see which components were last inspected. 

Mini excavators that use telematics systems typically have a screen in the cabin that alerts the operator when a problem occurs. The system also provides service alerts to help plan maintenance schedules. This approach allows operators to track maintenance and avoid overlooking problems, potentially saving hours of downtime.

Genuine Cat Engine Air Filters and Their Guide to Use

Your heavy equipment can work in some challenging environments. Job sites are often dusty and dirty, but the engines in your machines need clean air to run at peak performance. Rely on genuine Cat® Engine Air Filters to handle these conditions and avoid costly repairs.

What is an Engine Air Filter?

Engine air filters are essential for protecting delicate and hard-working engine parts from dust. These tiny particles interact with oxygen to create silica, which becomes abrasive when it enters your equipment's engine.

It's important to note the difference between cabin and engine air filters. Cat cab air filters keep the heating and cooling system running well and affect the air quality in the cab. They do not affect your machine's engine performance.

What does it do for your machine?

Cat machinery contains a two-stage filtration system. The outer or main filter is the first line of defense and tends to be dirtier than the inner or safety filter.

Both engine air filters have one common goal - to stop dust and debris from entering the motor and its components. Blocking these particles reduces wear on critical components.

Types of Engine Air Filters

Cat primary filters come in two general types – standard efficiency and premium efficiency. Secondary filters are standard efficiency only. Standard efficiency filters are ideal for general and light-duty machinery. They consistently provide engine protection and keep field equipment running at its best. Consider premium efficiency filters for more demanding applications or when a higher degree of filtration is required.

What Happens If You Don’t Take Care of Your Children

When your engine air filter becomes dirty or clogged, it can adversely affect the power of your engine. Your machine may not accelerate properly or may run slowly. In addition, you may experience:

·Misfires. ·Strange noises. ·Excessive or black exhaust. ·Premature engine wear. ·Increased fuel consumption.

Because your engine air filter is critical to performance, plan to monitor it regularly. We recommend changing the filter after 500 hours of operation or less, depending on the operating environment.
