CAT excavators are designed to perform various heavy-duty tasks on work sites. They can be used to dig, demolish, and tunnel.
Choosing the right machine for your job is essential for both safety and productivity. CAT excavators come in four sizes and several types, and each model offers different power and digging depths.
The pricing range for CAT crawler excavatorsdepends on some factors. These include the size of your job site, the configuration of your project, how much horsepower you need, and how deep you need to dig.
CAT offers four types of excavators for different tasks: demolition, long reach, wheel, and frontless. They come in sizes ranging from 65,000 to 80,000 pounds and offer 204 to 268 horsepower.
Demolition models are specifically designed for demolition projects. These include the 340 Straight Boom with 88500 pounds of operating weight and 314 horsepower, the 340F UHD with 117,103 pounds and 313 horsepower, and the 352 UHD with 151,483 pounds and 425 horsepower.
These models are heavier than the small excavators, which can help you get around corners and other spaces. They also offer auxiliary hydraulic options and can accommodate a variety of attachments. They can dig a maximum digging depth of nearly 43 feet.
A CAT crawler excavator and Caterpillar 972 hreach deep into the ground to dig, demolish, or tunnel. They’re the most common type of excavator used on construction sites today, and they come in various sizes and types.
They range from mini-excavators that can be used indoors to large machines that are perfect for demolition projects. These machines can be rented to handle just about any kind of digging job, but there are several factors you should consider in choosing the right one for your project.
You can rent a larger model from a CAT dealer if you need more power. They can also outfit the machine with specialized attachments that turn it into a value-added piece of equipment. These add-ons can increase the machine’s productivity and return on investment, making it a great choice for commercial and residential projects.
A hydraulic excavator is a complex system that requires many parts to work together. The engine, pumps, counterbalance, and control grouping are just a few of these.
These components are all designed to work together and play well off of each other to provide smoother, more efficient hydraulics than traditional systems. This helps the machine move tons of material efficientlywhile minimizing fuel consumption and maintenance costs.
The 972 h features load-sensing hydraulics that automatically adjusts to operating conditions to reduce fuel usage and provide only the implement's required hydraulic flow. This includes a dedicated Lift Mode to keep the power boost engaged when lifting heavy objects, like pipeline segments, and an enhanced Fine Swing Mode for improved swing control in placing pipes and trench boxes.
The transmission system of the crawler excavator 91, according to the invention, comprises a diesel engine 140 and a translation system for the rotary table 104. The translation system includes a rotary distributor with contacts (147) directly supplying power to two hub units 120 arranged at the back to determine the traction of each crawler, as well as a decoupling mechanism 150 connected to the motor and the generator.
The system is also adapted to reduce the number of electric motors required for translating propulsion, particularly by utilizing universal joint transmissions. Moreover, it is possible to use a reversible axial electric motor for commanding rotation and another reversible rotary axial electric motor to provide rotation movement to the drive wheels through suitable transmissions.
