Wheeled excavators are equipped with tire - based traveling mechanisms. Their driving speed is relatively high. Generally, the speed of domestic wheeled excavators ranges from 20 to 35 km/h, and some can even reach up to 54 km/h. This allows them to self - transfer over long distances and quickly reach different construction sites. As a result, transportation costs and time can be significantly saved. For example, in a large - scale infrastructure project with multiple construction sites spread over a wide area, a wheeled excavator can move from one site to another efficiently without the need for external transportation equipment.

It has the ability to rapidly change various operating attachments. These include buckets, crushing hammers, soil rippers, electromagnetic suckers, and quick - change devices. By using these different attachments, it can perform multiple functions such as digging, filling, crushing, and leveling, thus adapting to diverse construction requirements. In an urban construction project, for instance, it can switch from digging foundations with a bucket to crushing old concrete structures with a crushing hammer in a short time.

Equipped with a new - designed cab and seat, along with new interior decor and a new automatic air - conditioning system that features an automatic air - distribution function, it provides a comfortable operating environment. Meanwhile, a large - screen color display is installed to monitor the machine's running status in real - time. It also has a fault self - diagnosis and recording function, as well as an electric throttle and multiple working modes for operators to choose from. This enables operators to work more comfortably and efficiently, reducing fatigue during long - hour operations.

Some models adopt a large - area covering open design, allowing maintenance work to be carried out while standing on the ground. Components such as the air filter, crude fuel filter, fine fuel filter, oil filter, and pilot filter are all easily accessible. Moreover, the grease filling ports on the working device are centrally arranged, which greatly simplifies the maintenance process. This design not only saves maintenance time but also reduces maintenance costs, ensuring the machine's long - term stable operation.

It is widely used in various operating scenarios, including airports, ports, oil fields, mines, urban and rural construction, and farmland water conservancy projects. It is especially suitable for urban pipeline laying, material - handling operations, small - scale municipal engineering projects, and water conservancy projects. In urban areas, it can be used to install underground pipelines in narrow streets due to its flexible operation and relatively small size. In rural areas, it can assist in building irrigation canals and other water - conservancy facilities.
