Failure Analysis of a Mobile Crane: A Case Study

Identification and analysis of hoisting safety risk factors for IBS construction based on the AcciMap and cases study

“…More trustworthy equipment and environments are also worth attention [ 46 , [122] , [123] , [124] ]. According to our investigation, lift equipment often operates under corrosive gas dust containing acid and alkali, long-term operation of the collision, and anti-rust paint aging and shedding, so the surface loses protection, resulting in local corrosion and oxidation, thereby reducing the strength of the structure [ [125] , [126] , [127] ]. Subjecting the welds of essential rods and parts to techniques such as X-ray flaw detection, ultrasonic flaw detection, or magnetic particle flaw detection is imperative.…”

“…There are two ways for the crane cycle optimization: load path optimization [13][14][15][16][17][18][19], and hydraulic motor drive velocity optimization [20][21][22][23][24][25][26]. Transient accelera-tion/deceleration processes are highly important for the emergence of oscillations and high dynamic overloads.…”
