Why does the excavator have weak walking on one side?

[DelGiselle]

The reason for the excavator's weak walking on one side may be insufficient pilot pressure, worn oil seals in the central swivel joint causing internal leakage, wear in the hydraulic pump's LS valve, gaps or internal leakage in the distribution valve's valve holes, or wear and insufficient pressure in the hydraulic pump. Below is relevant information about excavators: Introduction: Excavators, also known as excavating machinery or diggers, are earthmoving machines that use a bucket to dig materials above or below the machine's surface and load them into transport vehicles or unload them to stockyards. Development: The main materials excavated by excavators are soil, coal, sand, and pre-loosened soil and rocks. From the perspective of the development of construction machinery in recent years, excavators have developed relatively quickly and have become one of the most important construction machines in engineering projects. The three most important parameters of an excavator: operating weight, engine power, and bucket capacity.
