Introduction

The increase in productivity in forestry is largely due to the increased level of use and improvement of existing ones, as well as the creation of new technologies. Caterpillar timber tractors equipped with various equipment have been widely used in many countries with a developed logging industry. This was facilitated by such advantages of tractors, high cross-country ability,. The use of special machines and differentials allows you to create machines whose cross-country capability is close to caterpillar machines.

Tracked tractors created on the basis of the LD19 are comfortable, high-performance. However, they have complex units and systems and make a high requirement for proper technical and productive operation, the choice of rational operating conditions for them.

This course design considers the structures and characteristics of existing loading machines, and developed a machine that meets the conditions of the task as much as possible.
