The house includes the operator cab, counterweight, engine, fuel and hydraulic oil tanks. Undercarriage can also have blade similar to that of a bulldozer. The undercarriage includes tracks, track frame, and final drives, which have a hydraulic motor and gearing providing the drive to the individual tracks. The boom, the front part that is attached to the cab itself and holds the arm, is also used. The three main sections of an excavator are the undercarriage, the house and the arm. The arrangement of the pumps in the excavator unit changes with different manufacturers using different formats. Generally, the 3 pumps used in excavators consist of 2 variable displacement piston pumps and a gear pump. The two main pumps supply oil at high pressure (up to 5000 psi, 345 bar) for the arms, swing motor, track motors and accessories while the third is a lower pressure (~700 psi, 48 bar) pump for pilot control of the spool valves this third circuit allows for reduced physical effort when operating the controls. Hydraulic excavators usually couple engine power to (commonly) three hydraulic pumps rather than to mechanical drivetrains. For example, Caterpillar's smallest mini-excavator weighs 2,060 pounds (930 kg) and has 13 hp their largest model is the largest excavator available (developed and produced by the Orenstein & Koppel, Germany, until the takeover 2011 by Caterpillar, named »RH400«), the CAT 6090, which weighs in excess of 2,160,510 pounds (979,990 kg), has 4500 hp, and a bucket as large as 52.0 m 3. The smaller ones are called mini or compact excavators. Modern hydraulic excavators come in a wide variety of sizes.

In the UK, wheeled excavators are sometimes known as 'rubber ducks'. Tracked excavators are sometimes called 'trackhoes' by analogy to the backhoe. Terminology Įxcavators are also called diggers, JCBs (a proprietary name, in an example of a generic trademark), mechanical shovels, or 360-degree excavators (sometimes abbreviated simply to '360'). Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators, which use winches and steel ropes to accomplish the movements. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.

They are a natural progression from the steam shovels and often mistakenly called power shovels, as power shovels may have similar looking buckets. The house sits atop an undercarriage with tracks or wheels.
