Compact excavators are smaller and more maneuverable than standard excavators, making them useful for small jobs and confined spaces. They have a cab, undercarriage, and working arm, with improved features like interchangeable tooling options and outriggers for greater versatility.
A compact excavator is a smaller version of a standard excavator specially equipped to take advantage of its size and agility. These machines have less power than a standard excavator but better maneuverability. They are useful for small jobs where more precision is required or for use in confined spaces where larger machines cannot reach. Newer versions of the compact excavator have additional tooling options; these are either permanently attached to the back of the device or are an interchangeable piece.
In many cases, a standard excavator has a fixed working boom and cab. This allows the machine to exert significantly more force in its work than a machine in which these points are movable. In return, the common excavator is very limited in its maneuverability. When an excavator is pulling material from a working area, it has a very limited choice of drop areas unless it moves after each scoop.
The compact excavator trades the power of the big machine for greater maneuverability. These machines are made up of three parts: the cab, the undercarriage and the working arm. Each of these areas is specifically set up to maximize the tool’s versatility.
The cab is the part of the compact excavator where the operator is while using the machine. The seat is moved towards the rear of the machine to provide a counterweight to the work arm. The cab is proportionately much lower than that of a conventional excavator, allowing the machine to work under lower ceilings.
The undercarriage is the part under the cab. This portion contains the hydraulic system that drives the work arm and the motor that drives the machine. It also features a pivot point that gives the cab and work arm the ability to rotate independently of the tread pattern. Operators can use this rotation to deposit material in a wider range of areas without moving the machine.
The last section is the working arm. The bucket at the end of the arm moves material into or out of a work area. This is usually a fill bucket, which means the digging end of the bucket faces the driver. The working arm has an independent oscillation from that of the cabin. It can rotate left or right, usually in a full 180 degree motion. This is especially useful in small areas where the cab is unable to rotate.
The latest versions of the compact excavator have improved features over previous models. These machines will have secondary equipment out back, such as an auger or lifter. This part typically requires the driver to rotate and usually causes the cab to be centered more on top of the wheels. More advanced versions have outriggers that can be interchanged with the conventional bucket. These give the small machine greater versatility and make it more attractive to small construction companies.
