Crawler excavators: selection and delivery

Selection starts with a technical specification: soil type, digging depth, working radius, requirements for transportation between sites.

These parameters determine the machine class and working equipment configuration.

For pit work in dense soils or rocky terrain, 30-50 t class machines with a reinforced arm and a hydraulic breaker are relevant.

For municipal construction or dismantling in urban areas - compact 13-20 t models with a reduced swing radius.

The most requested components in crawler excavator maintenance are: undercarriage elements (rollers, idlers, track chains), hydraulic system (pumps, distributors, cylinders), and a bucket with cutting edges.

ILIEV Solutions supplies original spare parts for Caterpillar, Liebherr, and XCMG with a complete documentation package.

For discontinued machines or in case of a limited budget - selection of high-quality OEM analogues from trusted sources in the markets of Europe, Japan, and China.

To identify a part, the machine's serial number (VIN) or the catalog number from the component's nameplate is sufficient.

Organizing repairs directly at the construction site or at the customer's base - is a part of service support.

This includes diagnosing the hydraulic system, restoring the undercarriage, replacing hydraulic pumps and distributors, as well as configuring electronic control units.

Minimizing downtime - is the main criterion when planning repair work.
