Analysis of the causes of accidents of the VIPO 32-01 hydraulic lift

Abstract

With the development of technologies, the number of accidents related to construction machines in one way or another increases. The article deals with the analysis of the causes of accidents of the VIPO 32-01 auto-hydraulic lift. According to the results of engineering and technical expertise, the cause of the accident was a break in the connection of the two upper traction chains with anchor bolts fixed to the main section of the boom. During this break, there was a spontaneous movement of the third and fourth sections of the telescopic boom of the auto-hydraulic lift. The main reason for the lack of strength of anchor bolts of the upper traction chains according to the results of the research was the use of steel grades with insufficient strength characteristics in their manufacture. Material did not have sufficient load-bearing capacity in the cross sections of the eyes of anchor bolts intended for fastening chains, for the perception of the calculated forces in the traction chains.
