Additional equipment - forest rope winch
Kovařík, Radim ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This work is focused on the design of a single-drum forest rope winch, which serves as an additional device for a universal wheeled tractor. The theoretical part of the work is focused on a general overview of the forestry techniques. The practical part deals with the calculation of basic functional parameters and strengths. Based on the calculated values, the actual design of the forest winch is created. Part of the design is the creation of a 3D model. Drawings of winch device, subassemblies of frame and drum are based on the created model.

Strength analysis of the frame for forestry cable yarder
Kovařík, Radim ; Halámka, Tomáš (referee) ; Mergl, Václav (advisor)
This work is focused on the strength analysis of the frame of the Larix Lamako forestry cable yarder rope, as an additional device of a universal agricultural tractor. The theoretical part of the work is focused on the basic description, determination of the area of use of the equipment and the distribution of forest rope transport equipment according to several criteria. The practical part of the work deals with the analytical calculation of force action. Based on the force action, the strength analysis of the original frame structure is numerically calculated. The numerical calculation is followed by structural modifications of the frame and numerical calculation of the modified structure. Assembly drawings of the original and modified structure are processed based on the original and modified equipment models.
