Glossary
- accessories
- non-essential components added to the machine to enhance the operation or extend machine longevity; for example: greasing systems, radio, air conditioning and extra lights. Although some accessories are non-essential to the machine operation, they are sometimes required in extreme operating environments.
- attachments
- components added to the machine that are integral to its operation to perform a specific job; for example: ripper, winch, thumb, hammer, tamper or forks.
- basic engine
- assembled block and head including internal components and gear trains.
- break-in
- a controlled operation specified by the manufacturer on new or repaired components to maximize service life.
- cold weather package
- accessories used to aid machine start-up and operation in cold weather environments; may include fluid heaters, extra batteries, glow plug systems, ether injection systems, heating pads and inlet air heaters.
- driveline
- the drive connection between a power source and a driven component.
- drive train
- the mechanical portion of the driveline from the flywheel to the tires or the track excluding hydrostatic systems.
- electrical systems
- starting, charging, lighting and accessory circuits without computer control modules.
- electronic systems
- electrical systems operated via computerized electronic control modules and related sensors and wiring.
- FOPS
- Falling Object Protective Structure.
- hydrostatic system
- a hydraulic system which uses fluid under pressure to transmit power through tubes or hoses to machine drive components such as wheel or track drives.
- operator station
- interface between the operator and the equipment’s other systems that enables operation and monitoring of the machine.
- overhaul
- rebuild or repair to like new condition.
- powertrain
- includes the drive train plus the engine (including hydrostatic systems).
- ROPS
- Roll-Over Protective Structure.
- sensory inspection
- diagnosing or inspecting using sight, sound, smell and feel.
- start-up
- a specific procedure to begin operation of a machine or system.
- structural components
- components that make up the integral structure of the machine; for example: frame, lift arms, booms, sticks, loader frames, counterweights, ROPS and FOPS.
- suspension
- components that support the main frame from the ground and may include undercarriage, axle and wheel assemblies.
- undercarriage
- track type components required to support the machine and transmit power from the final drive to the ground.
- wheel assembly
