“…In brief, crane safety research has been confined to trials, simulations, and methodological inquiries. Additionally, although risk-based maintenance techniques and technical diagnostic methods have received increasing attention in recent years [20], and although it known that cranes, as a group of the most widely used materials handling equipment, are responsible for up to one-third of all fatal cases in certain branches of industry, the creation of maintenance models for particular technological systems outside of the nuclear and petrochemical industries is moving too slowly. The key to successful risk management is early planning and aggressive implementation, but data on the condition of cranes, almost as a rule, in industrial companies in Serbia, are not collected, stored or analyzed up-to-date.…”

Maintenance is especially crucial when it comes to construction machinery due its capacity to avoid or reduce the risk of serious accidents by recognizing probable failures and downtimes in a timely manner. To properly implement maintenance strategy, it is required to identify the existing linkages between downtime and failures that have already occurred first. This paper aims to analyze and compare data on the length of downtime, as well as the causes of downtime hazard levels on different bridge and gantry cranes. In order to ascertain whether there is a dependency between these two types of cranes, a comparison of the failure duration and hazard level between bridge and gantry cranes is done in this paper. In addition, a comparison of nine different types of bridge and gantry cranes were compared using the same comparation categories. After performing descriptive statistics and the Kolmogorov-Smirnov and Shapiro-Wilk normality tests, which revealed that the data did not follow a normal distribution, a comparison was done using the Mann-Whitney U test and the Kruskal-Wallis tests. All tests revealed no statisticaly significant differences in failure duration and hazard level within the tested categories, which opens up the possibility of applying the same risk management strategies and maintenance procedures regarding both examined crane types.

“…Accidents are mainly the result of a combination of actions and causes. Wrong proceedings, usage with low visibility [4], unfavourable environmental conditions and tampering with safety devices are all actions that together with the lack of maintenance, mistakes in design and errors in installation may lead to accidents, ruptures and even collapse. There are a few researchers that have recently addressed the failure analysis of these structures, mainly investigating the influence of thermal excursion on cranes behaviour [5] as well as fatigue life of the K-type welded connections [6].…”

The paper deals with derrick cranes (derricks), that are equipment typically used in mining industry and the focus is the analysis of few robustness scenarios. Derricks are composed by built-up steel members, which are widely and efficiently used in hoisting applications, due to theirs high payloads at relevant outreaches. As during the in-service use local damages might occur, aim of the paper is to study how such damages should influence the overall structural performance. In particular, reference has been made to a derrick for which six geometrical configurations and five different damage scenarios have been analyzed. Owing to the extensive use of angles in the built-up component of each derrick, structural analyses have been carried out by using a commercial refined finite element analysis package (FEAP) offering the warping torsion as additional degree of freedom for each beam node. Research outcomes allow for a clear identify the parts of derrick which should be protected and well-designed to guarantee a robust structure for the total in-service life.

“…In that way safety would improve and crane related fatalities and injuries prevented. Dondur et al (2012) have proved that it is economically feasible to produce and use the new generation of crane cabins with considerably lighter weight and stiff structure, whose interior space is optimized, and proposed that all crane cabins should be developed by using the methods of physical, cognitive and organizational ergonomics.…”

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 theirinfluence 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.
