Wheeled excavators (referred to as wheeled excavators) refer to excavators equipped with tire travel devices. Compared with crawler excavators, they have the following characteristics:
1. Efficient and flexible
Strong mobility: wheeled excavators use tires to travel, and the travel speed is relatively fast (generally up to 30-40 km/h). They can easily transfer between different work sites quickly without the need for additional trailer transportation.
Adaptable to urban operations: It has a small turning radius and occupies a small area, which is suitable for construction in small areas such as cities and streets.
2. Easy to operate
The driving experience is close to that of a vehicle: equipped with a steering wheel or joystick operation, comfortable driving, especially suitable for short-distance driving and frequent movement.
Multi-purpose operation: By adding different attachments (such as grabs, breaker hammers, shears, etc.), it can meet a variety of use requirements, such as excavation, loading, crushing, etc.
3. Good environmental adaptability
Small damage to the ground: The unit pressure when the tire contacts the ground is small, and it will not cause significant damage to the ground (such as asphalt pavement, grass, etc.), which is particularly suitable for use in municipal and garden construction.
Limited climbing ability: Wheeled excavators are more suitable for flat terrain operations, and are not as stable as crawler excavators in complex mountainous or muddy environments.
4. Economy and cost
Relatively low energy consumption: Compared with crawler excavators, they consume less energy during walking and operation.
Low transportation costs: No need to use a flatbed truck for hauling, you can drive to the operation point by yourself within a short distance, saving transportation costs.
Convenient maintenance: Tire replacement is simpler and cheaper than crawler maintenance.
5. Relatively low stability
Higher center of gravity: Due to the limitations of the wheeled chassis, the center of gravity during operation is relatively high, and the stability is not as good as that of crawler excavators.
Limited application scenarios: Poor performance when large excavation force, rugged terrain or soft ground construction is required.
6. Common application areas
Urban and municipal engineering: such as road maintenance, pipeline laying, landscaping, etc.
Light earthwork: suitable for excavating light soil, carrying small stones, etc.
Multi-functional operation requirements: After changing the attachments, it is used for grabbing materials, clearing rivers, demolishing small buildings, etc.
Summary
The biggest feature of wheeled excavators is their strong mobility and flexible operation, which makes them particularly suitable for light and multi-functional municipal, urban and garden projects. However, due to their limited stability and traction, their applicable scenarios are relatively specific and they are not suitable for heavy loads and complex terrain operations.
