Excavator English

Excavator, also known as excavator, is a kind of heavy machinery and equipment used to excavate soil, sand and other materials. Usually widely used in construction engineering, road construction, mining, river dredging and other fields, it is an indispensable and important equipment in modern engineering construction. The English name of the excavator comes from the Latin "excavare", which means "digging".

Basic structure and principle of excavator;

The excavator is mainly composed of chassis, engine, hydraulic system, tipping mechanism and cab. It drives the movement of the arm, rod and bucket through the hydraulic system to realize the working process of digging, loading and unloading. Among them, the arm is a component connecting the fuselage and the bucket, the rod is a component connecting the arm and the bucket, and the bucket is used for digging and loading materials.

The working principle of excavator is that the driver controls the hydraulic valve in the hydraulic system by manipulating the joystick and pedal, so as to control the expansion and rotation of the mechanical arm and the opening and closing of the bucket. Drivers usually sit in the fully equipped cab and can clearly see the excavation area to ensure the accuracy and safety of excavation.

Types and uses of excavators:

There are many kinds of excavators, including small excavators, medium excavators and large excavators. Different types of excavators have different digging depth, loading capacity and applicable site. Small excavators are usually used in urban construction, small construction sites and farmland earthwork operations; Medium-sized excavators are suitable for small and medium-sized building construction, road maintenance and water conservancy projects; Large excavators are mainly used in large-scale foundation engineering, mining and large-scale earthwork.

In modern engineering construction, the role of excavators can not be ignored. It can efficiently excavate a large number of earth materials, improve the construction efficiency and shorten the construction period. Excavators can also be equipped with different types of excavators according to different working conditions to adapt to different types of soil and operation requirements. It has a wide range of operations, including digging foundation pits, cleaning rivers, digging canals, and digging mineral deposits.

Development trend of excavators;

With the progress of science and technology and the improvement of construction machinery manufacturing technology, the design and performance of excavators are constantly improving. Modern excavators are usually equipped with advanced hydraulic system, automatic control technology and intelligent equipment, which improves the accuracy, safety and reliability of excavators. At the same time, in order to meet the requirements of environmental protection and energy saving, the research and application of new materials and technologies have gradually improved the energy efficiency of excavators, reduced emissions and reduced energy consumption.

Generally speaking, excavator is an indispensable and important equipment in modern engineering construction, and its development trend is intelligence, environmental protection and high efficiency. With the continuous development of science and technology, excavators will play a more important role in various fields and contribute to the construction of mankind.
