Among the many key components of an excavator, the tie rod plays a vital role. The excavator tie rod is mainly responsible for transmitting the force generated by the hydraulic system to achieve various actions. When the operator operates the control lever of the excavator, the signal is transmitted to the hydraulic system. The hydraulic oil flows under pressure and pushes the piston in the hydraulic cylinder to move. The tie rod connects the hydraulic cylinder and the working devices such as the digging arm and bucket, converting the linear motion of the hydraulic cylinder into a specific action of the working device.
For example, in an excavation operation, when the hydraulic system pushes the hydraulic cylinder to extend, the tie rod pulls the digging arm downward to insert the bucket into the soil. When the bucket needs to be lifted, the hydraulic system operates in reverse, the hydraulic cylinder contracts, and the tie rod drives the digging arm to lift the bucket upward. By precisely controlling the pressure and flow of the hydraulic system, the tie rod can achieve precise control of the working device, thereby completing various complex excavation actions.
For second-hand dealers, the condition of the excavator tie rod is one of the important factors in evaluating the quality of second-hand equipment. When acquiring a second-hand excavator, they will carefully check the appearance of the tie rod for damage, deformation or cracks. If the tie rod has obvious damage, it may affect the working performance and safety of the excavator and reduce the value of the equipment.
At the same time, second-hand dealers will also pay attention to the connection parts of the tie rod to check whether there are problems such as looseness, wear or excessive gap. The poor condition of the connection parts may cause unstable movement of the working device and increase the maintenance cost of the equipment. In addition, they will also understand the use history of the equipment to determine whether the tie rod has ever been subjected to excessive load or used in harsh working conditions.
When selling second-hand excavators, second-hand dealers can introduce the importance of the tie rod to customers and how to properly maintain and maintain the tie rod. For example, remind customers to regularly check the connection parts of the tie rod to ensure that it is fastened and reliable; avoid applying excessive impact force to the tie rod during work; replace the tie rod parts that are severely worn in time, etc. By providing these professional advice and services, second-hand dealers can enhance customers' confidence in second-hand excavators and improve the success rate of equipment sales.
In short, as one of the key components, the working principle of the excavator tie rod directly affects the performance and operation of the excavator. When acquiring and selling second-hand excavators, second-hand dealers should pay full attention to the condition of the tie rod, provide customers with high-quality equipment and professional services, and promote the healthy development of the second-hand excavator market.
