What is an excavator boom
The excavator boom is an important part of the excavator, also known as the boom or main arm. It is a key component connecting the excavator body and bucket, responsible for transmitting power and completing operations such as excavation, loading and unloading. The design and performance of the excavator boom directly affect the working efficiency and stability of the excavator.
1. Structure and function of excavator boom

Excavator booms are usually made of high-strength steel and have the following main functions:
| Function | Description |
|---|---|
| Support bucket | The big arm is connected to the bucket to support it to complete the digging action |
| Transmit power | Power is transmitted to the bucket via a hydraulic system |
| Adjust the scope of work | Adjust the excavator's working range by telescopic and rotating |
2. Types of excavator booms
According to different operating requirements, excavator booms can be divided into the following categories:
| Type | Features | Applicable scenarios |
|---|---|---|
| Standard boom | Moderate length, suitable for general excavation operations | Construction sites, earthworks |
| Extended arm | Longer length, wider working range | River cleaning and deep pit excavation |
| Short arms | Short length and high flexibility | Working in narrow spaces |
