Selecting the best possible cranes and identifying spatial conflict-free locations on sites can result in productivity and safety improvements for large-scale industrial construction projects. In the current practice, experienced lift engineers select cranes based on the heaviest lift and/or the largest lifting radius of the identified crane. This practice is relatively time-consuming, and opti...

The path generation for a redundant sensor guided coal unloading crane is discussed in this paper. After using much of task specific knowledge to restrict the possible Tool Center Point (TCP) trajectories to a feasible subspace, two approaches are analyzed to optimize the dig head trajectory in this subspace: a Fuzzy Logic and a Dynamic Programming based trajectory generation. Experimental resu...

SCADA is the acronym for "Supervisory Control And Data Acquisition." SCADA systems are widely used in industry for supervisory control and data acquisition of industrial processes. Conventional SCADA systems use PC, notebook, thin client, and PDA as a client. In this paper, a Java-enabled mobile phone has been used as a client in a sample SCADA application in order to display and supervise the ...

Mobile cranes with hydraulic drive refer to cyclic machines that are used perform installation and other types of work. In accordance the operating conditions these cranes, question arises about effectiveness their use in performing labor-intensive The article is aimed at determining a number indicators for assessing state lifting mechanisms composition mobile design, production operation effic...

The interactive visual simulation is the integration of real-time computer graphics with multimodalities, such as acoustic display and force feedback, to create a realistic simulation scenario to the user. This paper presents a method to design an interactive visual simulation on a cluster of desktop computers for the mobile crane training. This mobile crane training simulation is a project spo...

The control design for decentralized active damping of large-scale manipulators with hydraulic actuation is considered in a distributedparameter framework. The concepts of modern light-weight construction enable the production of machines like mobile concrete pumps or maritime crane systems with extended operating range and less static load. However, due to the reduced weight the elasticity of ...

In the industry of forestry cranes, the design of automated machines that improve productivity has been a challenge for many researchers and engineers in the field of Control Systems and Robotics. An appropriate control design requires a detailed knowledge of the physical phenomena involved in the real system. At this point it is needed to perform simulation tests more rapid than experimental o...
