Apr. 10 2025 Maintenance By R & M Equipment

An excavator is a crucial piece of heavy machinery involved in many construction, mining, and earth-working projects. Each part serves its purpose to the function of the machine as a whole. In this blog post, we'll shed light on the essential parts of an excavator and their respective roles.

The Boom

Considered as one of the most significant parts, the boom offers a great deal of flexibility and reach. Connected directly to the house structure, it moves up and down, enabling access to hard-to-reach areas.

The Stick

Often referred to as the dipper or the arm, it's attached to the boom and extends outwards. It works together with the boom to dig and scoop soil or other materials.

The Bucket

The bucket is at the forefront - digging, lifting, loading, and carrying materials. It comes in different shapes and sizes which can be customized for specific jobs such as rock blasting or grading.

The Cab

Located on top of the house structure, this controlled space is for operators. Fitted with control levers or joysticks managing all machine operations makes it vital for any successful excavator operation.

The Undercarriage

The undercarriage provides mobility supporting travel over uneven ground. Includes tracks, track frames, and hydraulic motors that enable movement.
