Excavators are used for digging holes, landscaping, lifting and placing large objects, and demolition. Other tasks can be also completed by using hydraulic attachments such as grapples, shears, multiprocessors or hammers. The first CAT hydraulic crawler excavator was made in 1972 — the 225, which weighed 25 tonnes and had a performance of 100 kW. In 2018, Caterpillar started to produce new three next-generation excavators in 20-ton class - the 320 GC, the 320 and the 323 with increased operating efficiency, lower fuel consumption and lower maintenance costs. In 36-ton size class, Caterpillar produced the 336 and 336 GC crawler excavators. These new Cat excavators are capable of bigger productivity at lower costs and offer reduced maintenance costs and fuel consumption by up to 15 percent over the previous series. They are also equipped with the Cat LINK™ hardware and software, which connect job site with the office and send important information to customers. Customers can choose between Comfort, Deluxe, or Premium cab packages.

Cat also offers demolition excavators - the 336FL, the 340F UHD, and the long reach excavators: 340F LRE and the 352F LRE. Caterpillar excavators are standardly equipped with warning systems such as critical engine oil pressure, coolant temperature and oil temperature. The hydraulic tank, control valves, and main pumps are located close together to allow shorter lines between components, reducing friction loss and pressure drops. Machines such as Caterpillar 340F L or Caterpillar 325F are furnished with Caterpillar’s so-called VisionLink® and Product Link™ technologies which connect clients with their job site and providing business information, which increases production and minimizes operating costs. The owners can see where their machines are and what are they doing at that moment, how much fuel they consume and how much power is used. This helps to prolong the service life of machines. Caterpillar crawler excavators can be further divided into small excavators (CAT 313F), medium excavators (CAT 323), large excavators (CAT 390F L) and demolition excavators CAT 340F UHD) categories.

Caterpillar 's wheel loaders are very versatile. Although they are mainly used for loading and unloading various material and digging, they can operate in agriculture, forestry and the mining industry. Even combat engineering uses armored Caterpillar wheel loaders for missions in militarily occupied territories. Caterpillar introduced its first wheel loader in 1959 — the 944A. At that time, the wheel loaders were called the “Traxcavators.” Caterpillar 944A was different, because it had wheels instead of trucks and was equipped with twin lift arms instead of a vertical mast. It was given a four-cylinder Cat® D330 Diesel Engine. The name was formally changed from “Traxcavators” to “Wheel Loaders” in 1965. In 1963, Cat launched the 988 and the 966B articulated steering wheel loaders. These were followed by Caterpillar 922B wheel loader (1962), Caterpillar 950 (1964), Caterpillar 980 (1966), Caterpillar 930 and Caterpillar 992 (both in 1968), and Caterpillar 920 (1969). In 2012, Cat followed with the H-series of wheel loaders with 986H and 988H models with the Cat C15 ACERT™ engine capable of net power of 300-310 kW, which is still available. In 2013, the K-series was added to the range, which contains Caterpillar 986K, Caterpillar 994K and 4 more models. Nowadays, Caterpillar offers its last M-series of wheel loaders, which was introduced in 2014. It includes CAT 906M wheel loader, CAT 982M and 13 more models.

Caterpillar also added the XE Advanced powertrain, first introduced with the 966K XE, continuing with CAT 966M XE, CAT 988K XE, and the new Caterpillar 972M XE joining the product line. Within the XE technology is 25 percent lower fuel consumption, than in machines with traditional torque converters. Caterpillar’s offer of wheel loaders ranges from compact wheel loaders with net power of 55 kW to large wheel loaders with net power of 726 kW and rated payload of 27 tons. CAT offers wheel loaders in various sizes and loading capacities from 0,9 m³ to 44 m³. The largest wheel loader, Caterpillar 994K, was introduced in 1990 for the first time and delivered a performance of 1297 kW conforming with the new Tier 4 Final/EU Stage V emission level. Over the years Caterpillar wheel loaders underwent many safety improvements like LED warning system, higher cab position for better visibility, six mirror system, and Cat Detect, which includes Cat Vision, thus enhances operator awareness around the machine.

A skid-steer loader is a small, rigid-frame machine with lift arms used to attach a wide variety of tools or attachments like buckets, hammers, grapples, trenchers, shears, etc. First Caterpillar skid steer loader was the 216, launched in 1999. CAT skid steer loaders were basically invented as a mixture of mini-hydraulic excavators and compact wheel loaders. The first product line therefore began with Caterpillar 216, immediately followed by CAT 226 and finally growing to eight models ranging from 35 kW to 79 kW (47 hp to 106 hp). CAT 216 provided a bucket capacity of 0,36 m³, just like Caterpillar 226. Other early Caterpillar skid steer loaders were for example CAT 246 (weight of 3,21 tons, bucket capacity of 0,4 m³, lifting force of 21,8 kN, CAT 3034 T engine rated at 55 kW/74 hp), CAT 247 (weight of 3 tons, bucket capacity of 0,4 m³, lifting force of 13,66 kN, CAT 3034 engine rated at 41 kW/55 hp), CAT 232 (weight of 3 tons, bucket capacity of 0,36 m³, lifting force of 17 kN, CAT 3024 C engine rated at 36 kW/48 hp) and CAT 242 (weight of 3,03 tons, bucket capacity of 0,4 m³, lifting force of 17 kN, CAT 3034 C engine rated at 41 kW/55 hp). Currently offered Caterpillar skid steer loaders have rated operating capacity from 635 kg to 1656 kg. These features make skid-steer loader, such as Caterpillar 216B Series 3, the most versatile machine on jobsite. The Caterpillar machines, like the 242D, include a quick coupler system, which ensure that work tools can be changed quickly and easily. The CAT Electronic Torque Management System provides maximum performance and production capability with optional two speed travel. Machines such as Caterpillar 262D skid steer loader contain high-efficiency hydraulic oil cooler, which lets the machine work longer and harder in higher temperatures, even with continuous performance.

Caterpillar backhoe loaders basically combine two machine-types. They are equipped with a loader-style bucket on the front and a backhoe at the rear. Backhoe loaders such as the CAT 415F2 IL can be used in urban engineering and small construction projects (building small houses, fixing urban roads, etc). Caterpillar produces backhoe loaders with Center-pivot or side shift frames and the buyers can choose between 2- or 4-wheel drive. Caterpillar started to produce backhoe loaders at 1985 by releasing the A-series. The first model was called the Caterpillar 416A and it was launched with a lift capacity of 2 tonnes and an operating weight of 6 tons. In 1989, CAT launched the B-series, which had a modified swing system for increased torque and speed (e.g. CAT 438 B 4x4). Later in 1996, the Caterpillar C-series for backhoe loaders with upgraded CAT 3054 4-cylinder diesel engine with a performance of 59 kW, followed. One example would be the CAT 438 C 4x4. The Caterpillar 416D came out in 2001 with the cleanest inhouse-built combustion engine Cat 3054 (e.g. featuring the CAT 442 D 4x4). In 2005, the E-series was introduced with a new Cat 3054C 4-cylinder diesel engine equipped with direct injection (coming into effect in e.g. the CAT 428E 4x4 backhoe loader). The machine’s boom was redesigned with improved digging force including increased hydraulic breakout force. In 2012, Caterpillar started to produce the succeeding F-series models such as the CAT 430F and CAT 420F. The F-series loaders were given the new Caterpillar C4.4 Acert DIT 4 cylinder engine - rated at 72 kW. This series also got a completely redesigned exhaust system, with the exhaust stack being run up the side of the cab which resulted in an increase of the operator’s visibility. The newest Caterpillar F2 series has been available since 2015, including the CAT 416F2 center pivot model.

A bulldozer is used to push large quantities of soil, sand, rubble, or other material during construction work. There is also a ripper placed behind the machine, which is determined to loose stuck materials. CAT dozers, such as the D6K2, have fully automatic four-speed lock-up clutch with added gear between the first and the second lock-up clutch for smooth shifting. Models like Caterpillar D10T2 are equipped with CAT Connect technologies as Product Link™, VisionLink® remote monitoring and Liquid Crystal Display securing operator’s comfort and providing better overall machine performance. The main case, front cross member and equalizer bar saddle are made from heavy-duty steel, which is very durable. Caterpillar bulldozers can be furnished with different kinds of blades: the High-Capacity Universal Blade is determined for pushing loads over a long distance, the Semi-Universal Blade is used when penetration is required. Cutting Edges made of DH-2™ steel and End Bits made of DH-3™ steel are optimal for tough materials. Caterpillar actually offers various sizes of dozers: small dozers (CAT D3K2, CAT D4K2, CAT D5K2), medium dozers (CAT D6K2, CAT D6N, CAT D6T, CAT D7E), large dozers (CAT D9T, CAT D10T2, CAT D11T/D11T CD) and waste handling machines (CAT D6N WH, CAT D6T WH, CAT D9T WH and 3 more). Moreover, these CAT dozers are available in two variations based on the undercarriage type — XL (extra long) and LPG (low ground pressure).

Caterpillar’s articulated dump trucks are mainly designed for transporting loads over rough terrain. Dump trucks usually use the all-wheel drive and consist of two basic units. The front tractor and the rear hauler which is connected by the joint which helps the machines adapt to uneven terrains. The Caterpillar dump trucks usually have six-speed gearboxes and go up to 55 km/h top speed in a straight line. The biggest Caterpillar articulated dump truck CAT 745 has a rated payload of 41 tons and heaped body capacity of 25 m³. The Caterpillar 745 also offers the highest power rate of 381 kW (511 HP). If you need a “smaller” machine, the 725 could be the right choice. The Caterpillar 725 offers 13,7 m³ of heaped capacity, a payload of 22,7 tons and a Caterpillar 3176 C-ATAAC- EUI engine with 209 kW (280 HP). The Caterpillar 725 dump truck weighs 21,7 tons, whereas the 745 is a 33,4 tons heavy machine.

Operators control the truck via the VisionLink™ technology which allows for daily tracking of productivity from the cabin with quick access to truck payload weights. Articulated dump trucks, such as the 23-ton heavy Caterpillar 725C2, are equipped with Cat Detect including Stability Assist which automatically notifies the operator whenever the dump truck breaches the threshold to unsafe angles and stops the operation consequently. Newest machines launched in 2017 are the Caterpillar 730 and the 735 dump truck. As usual, higher model numbers indicate a larger machine with stronger engine and better performance — the CAT 735 offers 20 m³ of dump capacity, 32 tons of payload and Caterpillar C13 Acert engine rated at 316 kW (424 HP) with Tier 4 Final/Stage IV emission regulation as well as a  7.47 m turning radius, whilst the CAT 730 is equipped with Caterpillar C13 Acert engine rated at 274 kW (367 HP) with Tier 4 Final/Stage IV emission regulation, dump capacity of 17.5 m³, a net load of 28 tons and a turning radius of 7,47 m. In July 2018, Caterpillar celebrated reaching the milestone of 50,000 sold and delivered articulated dump trucks, since 1985.

Off-highway dump trucks are specifically designed for use in mining and heavy-duty construction sites. They can travel up to 80 km/h speed forward and 17 km/h in reverse. The biggest Caterpillar dump truck is the 797F with Cat® C175-20 engine rated at 2983 kW (4000 hp) of gross power. Its payload is 363 tons (heaped). Off-highway dump trucks are equipped with VIMS™ 3G monitoring system, which provides the operator with data about payload and critical health status. Safety is very important for Caterpillar, and that is why CAT uses 10/10/20 Overload Policy, that assures smooth machine running even at 20% overload. These giant trucks are equipped with four wheel, forced oil-cooled, multiple disc brakes. An oil film between the brakes assures a longer life. Steel structures are made of mild steel, which provides flexibility and resistance to impact loads. CAT developed off-highway trucks specifically for mining, quarry and construction applications. The first Caterpillar off-highway truck was showed to the public in 1963 and it was called the 769, which weighed 35 tons. This truck could bear 23.3-cubic-yard capacity rear dump and it could travel about 67 km/h. In 1974, Cat introduced the 777 model with power of 650 kW, then in 1996 it was upgraded with the power of 699 kW and it was called CAT 777D. The D-series includes CAT 785D, CAT 789D and CAT 793D which are still available. Then came the E-series, which brought CAT 773E and CAT 777E models.

Caterpillar started the production of F-series in 2009, which replaced the B-series (manufactured since 2002). For example, compared to Caterpillar 797B, the 797F has a higher payload capacity and a more powerful engine. Caterpillar 797F has a payload capacity of 363 tonnes but CAT 797B could carry 345 tonnes. The engine power increased from 2513 kW to 2828 kW. Caterpillar also offers the 793F with power 1975 kW in the F-series. In 2012 at Bauma China, CAT was showcasing 772G off-highway truck with a payload capacity of 47,2 tonnes. Caterpillar 772G off-highway truck is driven by Cat C18 ACERT™ inline 6-cylinder diesel engine. Many of the great features are introduced on larger Cat G Series truck model 770G, which uses CAT C15 engine with net power of 356 kW and the 772G model equipped with the C18 engine with net power of 410 kW. The G-series also contains CAT 770G, CAT 773G, CAT 775G, and CAT 777G models. In 2015, Caterpillar began to produce the 794 AC model, which delivered a 291 tonnes capacity. This truck uses the Cat C175-16 engine with Cat AC powertrain. The Cat AC drive system gives better retarding, braking and machine control.

The milling machines category includes two separate, but similar Caterpillar categories of construction machinery: road reclaimers such as Caterpillar RM500B and cold planers such as Caterpillar PM620. Road reclaimers are used to pulverize the asphalt and mix it with additional base (optionally adding asphalt emulsion) to stabilize and improve worsened and damaged roadways. One of the first Caterpillar road reclaimers is the SM 350, manufactured in 1997-1999. Caterpillar SM 350 road reclaimer weighs 19,5 tons, its cutting width is 2438 mm, cutting depth 470 mm and it is equipped with Caterpillar 3406 B engine with power of 316 kW/424 hp. In 2000, Caterpillar replaced the SM-series with RM-series of road reclaimers (e.g. RM 350 B). Caterpillar cold planers such as the PM620 or the PM820 are used for removing parts of the surface (even the whole surface). The milled road surface can be later recycled and used as a construction aggregate in new pavement.

A tracked or crawler loader is a versatile machine used to load, carry, dig and push material around the worksite. Crawler loaders combine the stability of crawler excavators (tractors) with the abilities of wheel loaders. The history of Caterpillar’s crawler loaders dates back to 1953, when CAT introduced and released its first original hydraulic crawler loader, the No. 6 Traxcavator. In 1994, Caterpillar introduced the 933, the 973 and the 939 crawler loaders, which weigh 8,7 tons, 21 tons and 10,03 tons, respectively, and are equipped with buckets of 1 m³, 2,8 m³ and 1,2 m³. CAT 933 is powered by Cat 3046 DI diesel engine rated at 52 kW (69,7 hp), whereas the driving unit of CAT 939 is Cat 3046 T diesel engine offering 68 kW (91,2 hp) and Cat 973 crawler loader is equipped with Cat 3306 DITA engine rated at 157 kW (210,5 hp). During the upcoming years, Caterpillar launched consecutively the B, C, D and K series of crawler loaders.

A paver is used to lay asphalt layers on roads, which are later compacted by a roller. The hopper’s of asphalt pavers are often fed by large dump trucks. Caterpillar rubber tire pavers are more suitable for applications that require mobility and frequent relocating compared to their tracked counterparts. Since 1985, when Caterpillar entered the asphalt paver market, CAT produced efficient wheeled pavers such the AP 600. This model was introduced in 2006, it weighs 14,15 tons and its standard dimensions are 6,4 m x 2,5 m x 3,8 m (l x w x h). Caterpillar AP 600 wheeled paver can be hydraulically extended to 7,5 m of length and its maximum paving width is 4,7 m. CAT AP 600 is powered by Cat 3056 E-ATAAC engine rated at 129 kW (173 hp). Caterpillar AP600D offers better maneuverability supported by three steering modes including Travel, Maneuver and Pave. The Maneuver mode is unique, providing 1,4 m turning radius. The drive power of Caterpillar AP600D wheeled paver is provided by CAT C6.6 engine rated at 129.5 kW (176 hp), that meets EU Stage IIIA requirements. Quite interesting is also the usage of double operator’s station offering enhanced visibility. The operating weight of CAT AP600D wheeled paver is 18,2 tons and the hopper capacity is 6,5 m³. Caterpillar AP1000E wheeled paver offers turning radius of 0,5 m, maximum travel speed of 20 km/h, rigid electric screeds providing better stability, adjustable push roller, sensor mix delivery system and reversible augers and conveyors.

The loader reach of Caterpillar 574 is 6,9 m, offers load capacity of 14,5 tons and its maximum travel speed is 13 km/h.
A skidder is capable of a process called “skidding”, which is basically the transportation of cut logs from the forest or cutting site to a landing, where they are loaded onto trucks. Caterpillar skidders are four wheel drive tractors with diesel engine, robust protective structure, log grapple on the one side (sorting/bunching type) and dozer blade on the other side of the skidding tractor. Caterpillar 515 special skidding tractor is a 16,5 tons heavy forestry machine, introduced in 1996. Cat 515 is, similarly to Caterpillar 525, powered by Cat 3304 DIT diesel engine rated at 118 kW/159 hp (Cat 525: 134 kW/179 hp). The grapple capacity of Cat 515 is 0,74 m2, whereas Caterpillar 525 is capable of grappling 0,84 m2 - 1.16 m2 of material. In 2014, Caterpillar introduced newest series of special skidding tractors — The D series — including Cat 525D, Cat 535D, Cat 545D and Cat 555D.

In 2001, Caterpillar launched three models of the B-Series articulated dump trucks: the 735B, the 740B and the 740B EJ. These machines became revolutionary due to reduced exhaust emissions and more efficient operations than the previous D-series articulated dump trucks such as Caterpillar D300D, CAT D25D or CAT D400D. Caterpillar 735B and the 740B articulated dump trucks also featured an improved cab design with controls for easier machine handling, maneuverability and productivity. Caterpillar 735B is a lighter model (29,8 tons) than Caterpillar 740B (32,6 tons) with 19,7 m³ of dump capacity against 22,9 m³, provided by Caterpillar 740B. CAT 735B articulated dump truck also offers lower payload of 32,7 tons, whereas CAT 740B offers 38,1 tons of net load. Caterpillar 740B EJ is a ejector dump truck with rated payload of 38 tons, EU Stage IIIB Cat C15 ACERTTM engine of 365 kW (489 HP) and heaped capacity of 23,1 m³.

The D-series of Caterpillar articulated dump trucks, launched in 1989, includes older Caterpillar machines such as D25D, D250D, D300D and 3 more. The largest machine in this series is the D400D — 28-ton heavy machine with net load of 36,3 tons, dump capacity of 23,5 m³ and Caterpillar 3406 DITA engine rated at 287 kW (385 HP). Caterpillar D350D and the D300D share the same engine — Caterpillar 3306 DITA, but they differ in power as CAT D350D offers 213 kW (286 HP) and CAT D300D offers 194 kW (260 HP). A bit larger articulated dump truck, CAT D350D also offers 20 m³ of dump capacity and 31 tons of payload. Smaller D300D is equipped with 18 m³ dumper and 27,3 tons of capacity. Caterpillar D250D is something like a happy medium: 17,3 tons of weight, 14 m³ of dump capacity, net load of 22,7 tons and Caterpillar 3116 DITA engine of 164 kW (220 HP).
