What is a shovel excavator?
The shovel excavator is a common engineering machinery and is widely used in earth excavation, mining, construction and other fields. Its characteristic is that the bucket faces the front of the machine, and the boom and bucket are driven by the hydraulic system to complete excavation, loading and other operations. This article will introduce in detail the structure, working principle, application scenarios and popular models on the market of front shovel excavators.
1. Structure and working principle of front shovel excavator
A front shovel excavator mainly consists of the following parts:
| Part name | Function description |
|---|---|
| engine | Provide power to drive hydraulic systems and working devices |
| Hydraulic system | Control the movement of booms, buckets and other components |
| Boom | Including boom, stick and bucket to complete the digging action |
| Rotary platform | Supports the upper structure to achieve 360-degree rotation |
| walking gear | Tracks or tires, providing mobility |
The working principle of a front shovel excavator is to drive the boom and bucket through a hydraulic cylinder to complete excavation, lifting, rotation and unloading. It has high operating efficiency and is suitable for working conditions such as hard soil and rocks.
2. Application scenarios of front shovel excavators
Front shovel excavators are mainly used in the following fields:
| Application areas | Specific use |
|---|---|
| Mining | Ore loading, topsoil stripping |
| building construction | Foundation pit excavation, earthworks |
| water conservancy project | River dredging and dam construction |
| road construction | Roadbed excavation and stone loading |
