Deep within a mine, a mining explosion-proof vehicle experiencing sudden heavy steering poses not just a threat to operational efficiency, but a direct risk to underground safety. As the vehicle’s “command center,” the proper functioning of the steering system is critical. This guide details common steering system faults and their diagnostic methods.<\/p>\n\n\n\n

Begin by checking the level and condition of the power steering fluid. Low or contaminated fluid can directly cause steering failure. Next, verify that the steering pump’s output pressure meets specifications, which is a quick indicator of pump performance degradation. Also, inspect the condition of the filter, as a contaminated element can restrict fluid flow.<\/p>\n\n\n\n
