Tools for mobile crane selecting and locating

Abstract

Definition of types, amount and positions of cranes in construction site planning has a big impact on the overall productivity and cost effectiveness of a construction project. It is not rare, that engineers during preparation phase of construction fault in crane selection. It implies big financial losses for the company because of wrong crane rent. In visualisation of mobile crane operation in 3D is noticeable that working radius of the crane is considerably less then number listed in crane technical documentation (capacity chart). The built construction itself can reduce the crane radius when the crane boom snags the built object edge. Several computer applications were developed in order to help practitioners in selecting and using of cranes. In the paper is presented one version of non-commercial software tool (Mobile Crane Simulator) useful in construction preparation as a tool for selecting and locating of the mobile crane at construction sites. The tool was developed by authours of the paper. The principles of the tool creation are also explained.

The Cost Monitoring of the Construction Machinery with Using the Stochastic Progress-Based S-curves

“…The cost monitoring at the construction machines operation allows continuous comparison the planned cost with the actual cost, fast improvement of the deviations from the determined assumption and searching bottlenecks. The authors have pointed out to the fact that detailed cost planning is possible to obtain the economic advantage for construction companies [13], [14]. Assakkaf [15] stated that cost for construction machinery is the second most important factor (just after the construction resources).…”

Novi pristupi u određivanju učinaka građevinskih strojeva

“…Druga istraživanja su usmjerena na izbor strojeva i grupa strojeva za građenje prema kriterijima optimalizacije: kvaliteta, vrijeme, potrošnja energije [13][14][15]. Hewage i suradnici [16] pokazali su mogućnost smanjenja utjecaja zastoja na radu povećanjem motivacije radnika, odnosno upravljanjem ljudskim potencijalima.…”

Automatic design algorithms for securing the ground contact stability of mobile cranes

“…Alkass and Osama developed a simulation program to select cranes by using tools like database management, spreadsheet application programs, graphics, and simulation (Al-Hussein et al 1997). Similarly, Struková and Ištvánik developed a program to select the optimal location of mobile cranes considering the lifting location, weight and building shape (Struková and Ištvánik 2011). However, there was not enough detailed review on stability of the soil bearing force and the program was aimed at selecting cranes in consideration of lifting conditions such as the weight, height, and building shape.…”
