Contractors know there’s a lot more to earthmoving than pushing dirt. We know it too, which is why we here at Caterpillar focus on things that give you a competitive advantage in a competitive world.

Long lasting, hard working machines capable of getting the maximum work done, every day
The full choice of heavy construction equipment options – new, used, rental and rebuilt – whichever fits best with your immediate and long term needs

Financing and insurance plans that make equipment ownership and protection affordable
Work Tools and attachment options that make one machine versatile enough to do the work of many
Equipment and fleet management strategies that help predict, and control, your owning and operating costs

Training programs that improve productivity and safety for both experienced and new operators
Monitoring and control technologies that improve machine performance, accuracy, and operator efficiency

This site is organized to be a resource as you plan the project, deliver on your promises, and
improve profitability on every job -- because there is a lot more to earthmoving than pushing dirt.


Meet the people who bring sustainable energy solutions to the world. Caterpillar goes back to work with a CG line of products tailored to match each customer and each site's unique requirements providing reliable, integrated solutions with lower owning and operating costs.
The CG line of generators is designed for many applications; from high-efficiency greenhouse cogeneration systems to power for remote mining operations, to biogas powered electricity for food processing plants.



With today's focus on renewable energy and carbon emissions reductions, landfill-gas-to-energy projects are gaining momentum. These applications use Cat® generator sets to turn waste into economically viable electricity. Caterpillar continually researches, develops and delivers landfill gas products specifically designed to be operated on landfill gas fuels.

Extend equipment life and maintenance intervals for landfill applications
Deliver improved performance and reliability
Offer lower operating and maintenance costs
Reduce environmental impact

Landfill gas is produced naturally as organic waste decomposes in landfills. It is composed of methane, carbon dioxide and small amounts of non-methane organic compounds. As an important and growing application within the world's power generation mix, landfill-gas-to-energy systems collect, process and treat this gas for use in generating electricity. Two common approaches to landfill gas collection include vertical well extraction and horizontal collectors or trenches.

Municipalities generally use blowers or vacuums to direct the gas from a collection site through a network of pipes to a central facility. At most developed municipal solid-waste landfills, the methane and carbon dioxide are destroyed in a gas collection and control system or utility flare. The sustainable alternative is to divert the landfill gas from the flare to be used in electricity-producing Cat generator sets.

The diverted fuel is dried and sometimes refined to remove impurities such as:
Sulfur
Halides
Siloxanes (Silica)

After fuel treatment, the methane is introduced into a Cat gas generator set as fuel. Caterpillar offers sets specifically designed for operation at landfills with:
A crankcase ventilation pump to eject potentially acidic blow-by gases
Specially designed aftercooler cores, cylinder heads, main bearings, and connecting rod bearings that are hardened against corrosive elements

Differentiated cooling systems to operate at elevated jacket water temperatures to prevent condensation of contaminants
Cat switchgear with PLC-based controls is supplied to parallel the generators to the local electrical grid to export renewable power at a premium to the local electric utility.
