What is an excavator?

Excavators or trackhoes are pieces of heavy equipment consisting of a boom, dipper, bucket and cab on a rotating platform known as the “house”. The house sits on an undercarriage with tracks or wheels. Hydraulic fluid is used to create movement and functions with hydraulic cylinders and motors. 

What is an excavator typically used for?

Excavators are an extremely versatile piece of machinery that can be used for many functions such as digging trenches and holes, setting foundations, material handling, brush cutting, forestry work, forestry mulching, construction, and demolition with hydraulic claw, cutter and breaker attachments.

Additionally, they provide utility for general grading/landscaping, mining, river dredging, driving piles - in conjunction with a pile driver, drilling shafts for footings and rock blasting by use of an auger or hydraulic drill attachment - and snow removal. 

What is a crawler excavator?

Many excavators run on wheels, but crawlers run on two, endless tracks. Crawlers, also known as standard excavators or trackhoes, are often used in mining and heavy-duty construction jobs of larger scale.

What is a dragline excavator?

The dragline excavator is a larger excavator that operates with a different process than typical excavators. This style utilizes a hoist rope system that attaches to a bucket via a coupler.

What is a suction excavator?

Also known as vacuum excavators, suction excavators feature a suction pipe capable of up to 400 horsepower. The excavator first releases a water jet to loosen the ground. The pipe, which contains sharp teeth at the edge, then creates a vacuum that carries away soil and debris up to 200 miles per hour, or 322 kilometers per hour.
