Driving an excavator may seem like a majestic operation, but in fact, there are many things to worry about. First of all, equipment failure is undoubtedly a nightmare. If the engine fails, such as suddenly shutting down or failing to start, the work will be interrupted instantly, especially in some emergency working environments, the consequences will be disastrous. Not only that, the repair of engine failure is often complicated and expensive, which brings a heavy economic burden to the construction party. Problems with the hydraulic system are also extremely difficult. For example, hydraulic oil leakage or hydraulic cylinder failure will directly affect the working performance of the excavator and make it unable to operate normally. Hydraulic oil leakage may also cause environmental pollution and even safety accidents such as fire. Electrical system failure is also a headache. Abnormal dashboard display and dim lights will affect the operator's judgment of the equipment status and increase the risk of operation. Failure of key electrical components is more likely to cause the excavator to fail to start or stop normally, endangering the safety of the operator. For second-hand dealers, when purchasing second-hand excavators, they will carefully check whether the equipment has a history of these failures. If so, it is necessary to evaluate the maintenance cost and the impact on the value of the equipment. When selling, customers will also be truthfully informed of the condition of the equipment and provided with some possible solutions, such as recommending reliable maintenance channels.
Secondly, safety accidents are even more frightening. Landslides and landslides are like hidden demons in excavation operations, especially when working in unstable soil sites or mountains or slopes. Once they occur, the equipment may be buried or damaged, and the life safety of the operator is also seriously threatened. Collision accidents also occur from time to time. Due to the limited vision of excavator operation, it is easy to collide with other equipment, buildings or obstacles in narrow working spaces or complex construction environments, causing damage to both parties or even casualties. Rollover accidents are equally dangerous. When working on uneven ground or performing large movements, the excavator may overturn, which is a great threat to the life of the operator and will also cause great damage to the excavator. When facing a used excavator that may have a history of safety accidents, second-hand dealers will be more cautious in evaluating its residual value and potential risks. When selling, they will emphasize the importance of safe operation to customers and provide some safety training resources to reduce the possibility of safety accidents during use.
In addition, bad weather also makes excavator operation challenging. When heavy rain and floods hit, water accumulates on the construction site, which not only affects normal operations, but also floods, causing serious damage to the excavator. At the same time, floods can loosen the soil and increase the risk of collapse and landslides. Strong winds can affect the stability of the excavator, which is more obvious when working at high altitudes or large excavation operations, and may also blow up debris to injure the operator. In high temperature environments, the excavator engine and hydraulic system are prone to overheating, affecting performance and life, and operators are also prone to heat stroke. In severe cold weather, the excavator is difficult to start, the fluidity of the hydraulic oil is reduced, affecting the operating performance, and the cold may also cause damage to equipment parts. When purchasing a used excavator, second-hand dealers will understand the use of the equipment in bad weather and assess its potential degree of damage. When selling, customers will be reminded of the operating precautions and maintenance methods under different weather conditions to extend the service life of the equipment.
In short, there are many things that make people afraid of driving an excavator, and second-hand dealers play an important role in this process. They provide customers with more reliable second-hand excavators through careful inspection, evaluation and advice, and also contribute to the stable development of the excavator industry.
