Abstract

In the paper are shown selective elements of chassis of open cast mining machines: control steering track and caterpillar tracks of open cast mining machines. Loads on each element are defined in accordance with current standard requirements norms. After setting boundary conditions, stress analysis was done. Results of analysis are shown in the table. Indication of the most endangered places was based on the results of analysis. Strain gauges measurements were also performed in 9 measuring points: 6 points on track's supports, 2 on caterpillar’s support and one on steering control. The measurements were taken by multichannel recorder during the driving of the conveyor. The measurements were taken for many settings of the body and the chassis with different angles of steering set. After examination of the measurement results some figures were obtained that show turning of caterpillar sets, increasing and decreasing steering force and track force on caterpillar during driving and turning.
