Course detail

Forestry Logging Machines

FSI-QF0 Acad. year: 2024/2025 Winter semester

The subject is intended to familiarize students with the conceptual and structural solutions of forest logging and transport machines, especially harvesters, forwarders and timber trailers. Students will also be introduced to the hybridization of these machines and their solutions.

Conditions for granting credit: presence at the seminars

Aims

The aim of the course is to acquaint students with the conceptual and structural solutions of forest logging and transport machines, especially harvesters, forwarders and timber trailers, as well as their equipment (harvester heads, grapples, etc.). Furthermore, the aim of the course is to acquaint them with the specifics of logging, which affects the design of machines and additional equipment. Furthermore, the aim of the subject is to familiarize with the hybridization of the drive units of these machines, or examples of modular superstructures.


The student is able to design the working equipment of individual forestry, logging, and transport machines from the project and construction point of view, taking into account the technological process. The student is familiar with the individual construction nodes and their principles in progressive logging machines (harvesters, forwarders and timber trailers) involved in forest logging. Among other things, the student is able to describe the individual technological procedures of forest logging and implement its specifics in the design of the given machines.
