This study focuses on hydraulic hoses utilized in the hydraulic systems of forklifts. The investigation examined 8 forklifts, each with a loading capacity of 10 tons. The check took place every six months over a three-year span. Before and after each shift, the forklift operator performed visual checks and hydraulic system and brake а inspections. The research findings indicated that the most frequent hose malfunction was a result of a rupture. The failure rate noticeably increased during the winter, attributable to the low temperatures' adverse effect on the hoses' physical and mechanical properties. Another common area of hydraulic hose failure is due to substandard crimping and minimal fitting depth in the sleeves..
