In construction operations, the working efficiency of wheeled excavators is directly related to the project schedule and costs. The hydraulic system is like the "power hub" of a wheeled excavator. Once it has weak hydraulics and slow movements, it will bring about many serious problems. Therefore, never buy such wheeled excavators.
Weak hydraulics and slow movements first and foremost affect the operational efficiency. In work scenarios such as earth excavation and material handling, a normal wheeled excavator can quickly and smoothly complete a series of actions like digging, slewing, and unloading, efficiently accomplishing tasks. However, a wheeled excavator with weak hydraulics may not be able to quickly cut into the soil layer when digging, spending a lot of time but with limited excavation volume. During material handling, the slow movements lead to a significant decline in the handling speed. Take a small construction site as an example. A normal wheeled excavator can complete the handling tasks in one day, but a wheeled excavator with weak hydraulics may take two days or even longer, seriously delaying the project progress and increasing labor costs.
Moreover, when the hydraulic system operates inefficiently for a long time, it will cause excessive wear and tear on the equipment. To complete the work, operators often increase the throttle, putting the engine under high - load operation. This not only increases fuel consumption but also exerts additional pressure on key components such as the engine and hydraulic pump, accelerating component aging and wear. Over time, the service life of the equipment will be significantly shortened, and the maintenance frequency will rise sharply. Maintenance not only requires a large amount of capital but also results in long - term equipment downtime, further affecting the project progress.
In addition, weak hydraulics and slow movements may also pose safety hazards. In some working environments where high precision and timeliness of operation are required, the slow movements of the wheeled excavator may prevent operators from responding to unexpected situations in a timely manner. For example, when excavating near a building, if the wheeled excavator cannot stop its actions quickly, it may hit the building, causing a serious safety accident and endangering people's lives and property.
To sum up, wheeled excavators with weak hydraulics and slow movements have great drawbacks in terms of operational efficiency, equipment lifespan, and safety. When purchasing a wheeled excavator, be sure to carefully check the performance of the hydraulic system, and experience the smoothness and speed of the movements through a test run. Avoid buying such equipment that will bring many troubles and ensure the smooth progress of the project.
