Introduction. The paper discusses the applicability of a riskbased approach in the “personnel-machinery-production environment” system at the facilities running tower cranes through the introduction of IT-technologies that provide open communication of the staff, management team of the operating organizations, and the National Supervisory Authority, to reduce the accident rate. Materials and Methods. An example of a hazardous production facility running tower cranes is given. Materials on the analysis of operational status of tower cranes within the framework of the current legislation in the field of industrial safety are used. The necessity for innovations and transformations, one of whose methods is the risk-based approach allowing for the implementation of all required levels of control, is identified.Research Results. The stages of introduction of the riskoriented approach for tower crane operators implemented through IT-technologies using Web-applications on safety management under the tower crane operation based on the hazard analysis and risk assessment in gamut, algorithmically associated with the electronic block key of its local security system, are determined.Discussion and Conclusions. The application of a risk-based approach in the “personnel-machinery-production environment” system at the facilities running tower cranes through the introduction of IT-technologies will ensure the proper operation of all departments and each participant of the operation, as well as provide Supervisory bodies with an opportunity to access information on the operation for the implementation of control and supervision functions remotely.

Diplomsko delo predstavlja delovno mesto in poklic žerjavista, prepoznava nepravilnosti na delovnem mestu in podaja praktične primere za izboljšanje delovnih pogojev in počutja delavca. Obravnavano je delovno mesto žerjavista na stolpnem gradbenem žerjavu v gradbenem podjetju in njegove delovne naloge. Za prepoznavanje nepravilnosti na delovnem mestu sem sledila ergonomskim načelom. This thesis examines the profession and workplace of a crane operator. It stresses the irregularities at the workplace and gives practical suggestions for the improvement of working conditions and for workers’ well-being. The thesis focuses on the tasks and workplace of a tower crane operator at a construction company. The irregularities at the workplace were identified based on ergonomic principles.

Статья посвящена вопросам анализа спроса на рабочую силу определенной профессии на рынке труда. Определена сущность спроса на труд, доказана актуальность темы тем, что металлургия является одной из системообразующих отраслей экономики России, а машинист крана одна из наиболее востребованных профессий отрасли. Дано описание трудовых функций, выполняемых работниками по данной профессии. Проанализирована средняя заработная плата по должностям и рейтинг профессии машинист крана металлургического производства на первый квартал 2019 года, в том числе перспективы профессии, входной барьер, уровень конкуренции и др. Выявлено, что заработная плата по данной профессии выше среднерыночных. Автор проанализировала динамику количества вакансий и резюме, размещенных на портале HeadHunter, и выявила превышение спроса на труд над предложением, что говорит о дефиците рабочей силы по данным профессиям. Далее определены проблемы кадрового обеспечения отрасли, в том числе старение персонала, достаточно высокий уровень текучесть кадров, несоответствие качества подготовки кадров требованиям работодателя. Автором предложено внедрение специальных программ профориентации для пропаганды и привлечения школьников и студентов., The article is devoted to the analysis of the particular profession demand for labor on the labor market. The essence of the demand for labor is determined the topic relevance is proved by the fact that metallurgy is one of the backbone sectors of the Russian economy, and the crane operator is one of the most popular professions in the industry. The description of the labor functions performed by employees in this profession is given. The average salary by positions and the rating of the profession crane operator in metallurgical production were analyzed for the first quarter of 2019, including the profession prospects, entry barrier, competition level, etc. It was revealed that the salary for this profession is higher than the average. The author analyzed the dynamics of the number of vacancies and resumes posted on the HeadHunter portal, and revealed an excess of demand for labor over supply, which indicates a labor shortage in these professions. Further, the problems of staffing the industry were identified, including aging staff, a sufficiently high staff turnover level, and the mismatch between the training quality and the employers requirements. The author proposed the introduction of special career guidance programs for advocacy and attract schoolchildren and students., №4 (2019)

Purpose of this paper is application of method based on multivariate statistical technique in order to determine critical dimensions of the crane cabin, which would maximize adjustability and ergonomics of the product, resulting in accommodation of wider range of the population and greater safety while operating. Multivariate statistical technique used for this purpose is factor analysis. Results of this research, conducted on a sample consisted of 83 crane cabin operators, showed that while designing a working space critical anthropomeasures take three-dimensional space, while their influence contributions in each dimension are determined with factor analysis. Results of this work are expected to be useful for industry in a way such that crane cabins' designers can troubleshoot the dilemmas they encounter in their job. Using findings of this survey might lead to new designs of cabins that will offer less strenuous postures of operator, which consequently will improve productivity and safety.

The study was designed to determine the effect of joystick handle size and (display-control) gain at two levels of required task precision on performance and physical load on crane operators. Eight experienced crane operators performed a simulated crane operation task on a computer by use of a joystick with either a short or a large handle. The task was performed at three gain levels and at two levels of required precision. Task performance, wrist and forearm postures, upper extremity muscle activity, perceived exertion and perceived comfort were measured.Task performance improved when using the joystick with the short handle and when working at a higher gain, while physical load decreased or remained the same. An increased level of required task precision was associated with a lower performance, but physical load was not affected. External validity of the simulated crane task seemed sufficient enough to extrapolate the results to practice.A joystick with a short handle is recommended, as this leads to an increased performance whilst the operator's physical load decreases or remains the same. Further optimization of performance and physical load can be achieved by optimizing gain settings of the joystick in relation to the task and type of joystick used.
