Exercise 3. Slalom

Drive forward along a plain section of a road steering around delineators.

Exercise 4. Driving along control points in a pit (empty dump body)

Drive along the route from the upper bench to the lower bench with the empty dump body and observing the proper speed limit. There are crossings with dense traffic on the route.

Exercise 5. Driving along control points in a pit (loaded dump body)

Drive along the route from the lower bench to the upper bench with a loaded dump body and observing the proper speed limit. There are crossings with dense traffic on the route.

Exercise 6. Approach for loading

Perform a correct drive up to an excavator for loading, at the same time paying attention to the signals from the excavator operator and to the speed limit.

Exercise 7. Driving up to dump, unloading

Drive up correctly to the protective shoulder and carry out unloading.

Exercise 8. Loading-unloading cycle

Drive along the route from the upper bench to the bottom one up to the loading area, drive up for loading, carry out loading, drive along the route from the bottom bench to the upper one up to the loading area, carry out unloading. Loading must be carried out “for two drive-ups”, i. e. the excavator does loading of vehicles on the right side first, then — on its left. It is a full cycle exercise which is finished using the Cancel the Task button at the instructor workstation.

Exercise 9. Driving in and out of repair bay

Drive along the route up to the repair bay, drive into it in reverse, stop, shutdown the engine, drive out of the repair bay.
