Accident Analysis of Using Small Cranes
2019-08-21 15:06:06
Non-human factors analysis:
1The concrete condition (such as specification, weight, etc.) of the construction party's failure to supply the driver with the lifting object. When the crane is hoisted, the jointing arm is still lying in the closed cabin. Before the crane is lifted from the cabin, the driver cannot specifically Query and estimate the weight.
2 Sedan cranes do not have a torque limiter device, and then they cannot provide the driver with precise skill parameters to prevent the onset of such events.
Analysis of human factors: 1 The driver violated regulations and did not strictly follow the strict rules of various skill parameters when the crane was hoisted. The effect caused the jib to be too long and the jib height was too high, and then triggered a seizure. 2 The driver's lack of work experience, numbness of thinking, and after placing the crane, blindly lifted the object when the object to be lifted had not been carefully examined and evaluated. 3 Vehicle Disposal Some of them lacked disposal and they were unable to organize someone to conduct on-site command during the lifting operation.
Small crane accident prevention measures: (1) Strengthen the rules and regulations for safe operation of Chinese small crane drivers so that they can skillfully grasp the relevant skills. 2 Strictly follow the requirements of laws and regulations such as “The Law of Special Equipment Safety Supervisionâ€, the driver must be certified to work, and the vehicle should be checked, monitored, etc. on time. 3 As for the operation items at the extra site, the lifting unit shall carry out specific inquiry certification, and draw up a specific operation plan. It shall also organize full-time personnel to conduct on-site command. 4 Torque limiters are installed on the vehicle to fundamentally eliminate potential safety hazards due to overload. 5 When selecting a hoisting site, it is necessary to select a flat and strong open site without looseness, depression, and sewer manhole cover. 6 protect and protect the vehicle, to ensure that the vehicle is in an unavoidable skill condition, in particular, it is necessary to check the appearance of the main arm, the support leg cylinder, the support pad, and the amplitude change cylinder for cracks and oil leakage.
