Product Description:

Description of excavator:


Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators.


Modern, hydraulic excavators come in a wide variety of sizes. The smaller ones are called mini or compact excavators. 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 (a record previously held by the Orenstein & Koppel RH400) the CAT 6090, it weighs in excess of 2,160,510 pounds (979,990 kg), has 4500 hp and has a bucket size of around 52.0 m³ depending on bucket fitted.


The two main sections of an excavator are the undercarriage and the house. The undercarriage includes the blade (if fitted), tracks, track frame, and final drives, which have a hydraulic motor and gearing providing the drive to the individual tracks, and the house includes the operator cab, counterweight, engine, fuel and hydraulic oil tanks. The house attaches to the undercarriage by way of a center pin. High pressure oil is supplied to the tracks' hydraulic motors through a hydraulic swivel at the axis of the pin, allowing the machine to slew 360° unhindered.

FAQ of excavator:

Q: What are the main functions of excavators?

A: Excavator is the machine that can excavate the the soil of various types forcefully and then using hydraulic system a hydraulic force is generated and utilizing this force bucket is exchange with some other attachments then excavator can be used for multi-purpose. For exemple pile diver, hydraulic jack hammer etc...


Q: What are the main type of excavators?

A: Crawler excavator; Wheel excavator;


Q: What is the application of excavators?

A: The excavator has increased the work speed tremendously. It is used extensively in numerous fields, including the following:

•Wood removal in forests

•Normal grading work and landscaping

•Cutting of brushes with attachments

•Demolition of structures, and removal of debris
