New generation of CAT excavators

CAT excavators

The brand produces mini excavators /CAT/ with a weight range from 1 to 10 tons and offers C, D and E machines. CAT excavators are characterized by high work efficiency and reliability, even in very difficult conditions. Their small size guarantees work in hard-to-reach places, directly next to fences or other vertical obstacles, such as walls.

C series

At the beginning of 2019, Caterpillar launched new mini-excavator models from the C series – 301.6C, 301.8C and 302.5C. Before undertaking project work, the company asked operators and CAT owners about what they would change in their machines. The most frequent answers were suggestions for increasing power, reducing noise or improving durability.

As a result, /CAT/ mini excavators with a spacious cabin providing excellent visibility were created . Moreover, the operator has a lot of legroom (the cabin is extended by 50 cm), and cushioned seats and adjustable wrist rests provide comfort for many hours. Properly arranged controls elements, that don’t require effort when using them, are very easy to use. Engine instrument panel are placed in the operator’s eye range. That make it easier to read the fuel status or water temperature.

The engines efficiency is comparable to previous models (13.5 kw – 18.6 kw). However, the change of engine oil and filter takes place in 500 hour intervals.

D series

Mini excavators in this series are characterized by high power, which works well on limited space. Models 301.7D, 302.2D and 302.4D are equipped with an auxiliary hydraulic system with two-way flow. It can handle both a hydraulic hammer and two-way tools, such as an auger. Thanks to operating elements equipped with pilot control, work runs smoothly and effortlessly. The excavator’s blade increases the overall capabilities of the machines, facilitating the backfilling of excavations and othercleaning works. The free-motion function allows the blade to adapt to the ground shape. Thank to which cleaning the workplace is quickly and easily.

The useful power of all three models is 13.2 kW, digging depth 301.7D 2193 mm – 2394 mm, model 302.2D 2478 mm – 2678 mm, while 302.4D 2434 mm – 2634 mm. The engine oil is changed every 500 hours, hydraulic oil every 3000 hours. Similarly to the newer version of the C Series, the operator has a comfortable cushioned seat in the spacious cab, roll-up seat belts, adjustable armrests and plenty of legroom.

The 300.9D mini excavator weighs less than a ton and its overall width is 730 mm. It also has a sliding chassis and blade, thanks to which it can easily pass through narrow corridors and doors. The 13.7 kW engine guarantees efficient, reliable and economical operation.

E series

E Series include 303.5E CR, 304E CR, 305E CR, 305.5E CR and 308E CR SB models. They have a new specially designed COMPASS digital control panel. It is a complete system for managing maintenance, performance, control and security.

All five machines are characterized by high work efficiency, inherited from the previous D series models. According to the producer, they have a better arrangement of controls. What’s more, the E Series have the function of operating in economy mode. Appropriate speed control can reduce fuel consumption up to 20%. In the control panel there are settings for various types of equipment so that the excavator operator does not have to enter them from scratch.

E-series models feature a 200-degree bucket rotation. And their shape allows to maximize of the material picking while maintaining high digging is still efficiency. It also provides easier vertical digging without having to change the machine position.

As you can see, the Caterpillar hydraulic mini excavator range is quite wide. The brand aims to improve its models because the mini-excavator market is constantly growing. Their recipients are not only large companies, but also small, often one-person businesses and private persons.
