Repair and service excavators in the eBook
An excavator is a self-propelled machine capable of rotating 360 degrees and equipped with a boom and bucket, used for excavating and moving earth or other materials.
Excavators occupy a leading position in popularity among special equipment due to their versatility and wide range of applications. This equipment is actively used in the construction industry, agriculture and other industries. The main task of excavators is to perform loading and unloading and excavation work, which makes them indispensable at most sites.
Modern excavators are equipped with the latest technologies that significantly expand their functionality. Every year new models appear that can perform even more tasks, which makes this equipment increasingly popular.
One of the key characteristics of excavators is the type of undercarriage, which determines their mobility, efficiency on various types of soil and the ability to move around the object of the task. The success of the tasks depends on the correct choice of undercarriage.
The most common types of excavators include:
-
Crawler excavators
They are characterized by high cross-country ability and stability, especially on loose or difficult soils. They are ideal for work on construction sites and in off-road conditions. -
Wheeled excavators
They have high mobility, due to which they are suitable for work in urban areas and on hard-surface sites. They move between work areas faster. -
Floating excavators
Specialized machines designed for work on water or marshy areas. They are equipped with pontoons, which allows them to effectively perform tasks in high humidity conditions. -
Railway excavators
They are used to perform work on railway tracks. They are equipped with special wheelbases that allow them to move along rails.
The choice of the appropriate type of excavator depends on the operating conditions and the nature of the work performed.
A well-maintained excavator lasts longer and requires less repair costs, which is confirmed by all manufacturers of special equipment. However, in practice, not all owners follow the maintenance recommendations, which leads to premature wear of the machine.
The operating manuals describe in detail the scope of work and the maintenance schedule for excavators, depending on the number of operating hours. Manufacturers recommend carrying out scheduled maintenance, following the principle: "from a simple check to cleaning, adjustment and replacement."
During the operation of an excavator, wear, deformation and destruction of parts, loosening of fasteners, violation of gaps and adjustments inevitably occur. Scheduled maintenance is aimed at:
- preventing wear of parts;
- restoring correct clearances and adjustments;
- strengthening fasteners;
- ensuring stable operation of all systems.
Timely and high-quality maintenance helps to avoid breakdowns and extends the service life of the excavator, minimizing downtime and repair costs.
Daily maintenance of the excavator includes mandatory inspection of the engine, checking the level of oil and hydraulic fluid, lubrication of connections, and cleaning dirt from critical components. Particular attention is paid to the piston of the hydraulic cylinder, since contamination can damage the seals and reduce the efficiency of the machine.
Scheduled maintenance is carried out by specialists of service centers, since it requires the use of specialized devices to monitor pressure, flow of working fluid and oil. Samples are also taken and analyzed to ensure correct operation of the equipment and extend its service life.
