Experimental Studies to Determine the Ground Pressure of the TROM 25 Wheeled Log Picker

This paper presents a rationale for developing a technical solution based on industrial all-terrain vehicles with ultra-low-pressure pneumatic tires. The implementation for the forestry industry consists of the design and manufacture of the studied TROM 25 wheeled timber picker. The values of the contour contact area of the tread contact patch of each measured wheel of the TROM 25 wheeled timber picker were measured. The maximum normal pressure on the soil of the TROM 25 wheeled timber picker( 8x8 wheel arrangement with Trom wheel equipment, 1960x900R38, and tire pressure of 50,000 Pa) were determined. The experimentally measured contact area of the TROM 25 wheeled timber picker (8x8 wheel arrangement with Trom wheel equipment, is indicated – 1960x900R38, and tire pressure is 50,000 Pa). A scientific innovation has been developed to determine the values of the contour contact area of the tread of each of the steering wheels, as well as to determine the contact patch of an ultra-low pressure pneumatic tire with the final support surface for forestry. The research resulted in the determination of the actual measured ground pressure of the TROM 25 wheeled timber picker, and recommendations for applying the results in real-world environmental and production conditions were provided.
