Robotics for hazardous environments is one of the most important and fast growing areas in the robotics industry [4, 5, 6, 12]. This area focuses on providing a high level functionality in arenas where humans cannot safely or cheaply work. However, the usefulness of the robot in hazardous situations is highly dependent on its reliability. Hazardous environments can damage robotic components, ar...

Mobile cranes are used to lift heavy modules in industrial projects. These heavy modules are often prefabricated and each project consists of a large number of lifts (e.g., a typical industrial project may have between 150 and 1000 modules to be lifted). To ensure the safety and efficiency of these lifting activities, crane motion planning is needed. However, in practice, most of the heavy lift...

The hydraulic system of mobile garbage compression equipment was studied according to its actual working conditions. A simulation model of the hydraulic system was established with AMESim software, and the speed and acceleration of the piston rod were simulated. Simulation results show that the designed hydraulic system can achieve the action requirements. The experiment also shows the similar ...

The load-sensing system has for a long time been the most energy efficient hydraulic widely used mobile machines. When replacing combustion engine drive with an electric battery as source incentive using more systems arise. Some promising examples of are independent metering systems, pump controlled and open flow control systems. Before getting to deeply involved in specific design, investigati...

yard crane is an important resource in container terminals. efficient utilization of the yard crane significantly improves the productivity and the profitability of the container terminal. this paper presents a mixed integer programming model for the yard crane scheduling problem with non- interference constraint that is nphard in nature. in other words, one of the most important constraints in...

The design, dynamic modelling, and workspace are presented in this paper concerning cooperative cable parallel manipulators for multiple mobile cranes (CPMMCs). The CPMMCs can handle complex tasks that are more difficult or even impossible for a single mobile crane. Kinematics and dynamics of the CPMMCs are studied on the basis of geometric methodology and dʹAlembert’s pr...

A load moment indicator (LMI) is an electronic device on heavy equipment cranes that can provide information and a warning system to operators in the event of overload during lifting process. This tool has very important role because it provides accessible operator about safe working (SWL) crane lift. Mobile have high accident potential when compared tower cranes, this mobile mobility. In paper...
