The Forensic expert kollegium carries out expertise of all types of logging equipment.
Depending on the operations performed, a distinction is made between felling, skidding, delimbing, debarking, feller-bunching, feller-skidding, delimbing-bucking, logging machines, etc. caterpillar plants.
The designs of harvesting machines are very diverse and depend on their purpose. However, differing in design, logging machines have units and parts for the same purpose. Harvesting equipment, as a rule, operates under heavy and uneven loads, as a result of which some of their units fail. From expert practice of the Forensic expert kollegium, failures of the following units of logging machines most often occur:
- elements of hydraulic drive of various systems of harvesting machines (hydraulic motors, hydraulic pumps);
- electronic sensors of position, displacement, length, etc .;
- load-bearing structural elements (columns of manipulators, suspension links, etc.);
- compressors, radiators, cooling fans and other devices.
The reasons for the failure of units of logging equipment can be:
- manufacturing defects of assemblies and parts (mismatch of strength, plastic properties of parts, improper assembly, presence of structural defects in metals and alloys, etc.);
- improper performance of work on the repair and maintenance of logging machines (for example, the use of unacceptable brands of lubricants, insufficient or excessive amounts of them, untimely or poor-quality replacement of consumables, etc.);
- defects associated with the operation of logging machines (mechanical damage caused by operator errors, overload, natural wear of parts and assemblies).
The Forensic expert kollegium conducts expertise of logging machines for operability and compliance with the requirements of design documentation and technical regulatory legal acts, analysis of the causes of defects and equipment failures, destruction of units and parts. While carrying out the expertise, the experts of the Forensic expert kollegium use the methods of both non-destructive (flaw detection, vibration diagnostics) and destructive testing (metallography, analysis of chemical composition, mechanical properties, etc.).
If necessary, while conducting expertise of logging equipment, specialists of the Forensic expert kollegium perform engineering strength calculations. Calculations of the strength properties of forest machine units are carried out using licensed software - the KOMPAS 3D-V16 computer-aided design system with the APM FEM strength analysis system.
