Abstract :
Load gripping devices are used in any lifting operation and are used to attach the load to the construction machine, in most cases, to the crane hook. The most important quality of the product — safety-depends on the correct choice of the device, its technical characteristics, reliability parameters, as well as competent operation and application. The article presents an analysis of methods and approaches to assessing the risk of using load gripping devices when performing lifting operations. The problem of designing a clamping action grip for lifting the load with the possibility of turning from a horizontal position to a vertical one is described. The hazardous situation and the likelihood of operator error in the slinging of cargo. The practical example of reduction of risk of operation of the load gripping device for the purpose of increase of safety at its use is considered. The necessity of application of the term «safety culture» for all stages of life cycle of load gripping devices is explained and the necessity of preliminary preparation of design and operational documentation in interrelation with technological features or possibilities of concrete production is pointed out. The result has been achieved by the introduction into operation of the design of the clamping action for lifting the wheel in conjunction with the safe working methods reflected in the product data sheet and in the operating manual. The conclusions emphasize the need to expand the experience gained to other types and types of seizures, the need to systematize and summarize the experience gained, as well as the accumulation of statistical data.
