Quayside Container Crane

The heavy quayside container crane is the key equipment of handling production in container terminal, because the general simulation system can not provide the detail information of the single crane unit during working process, this work proposed a novel method to visualize the working process of the crane. Analyzed the basic mechanisms and typical working condition, based on which, discussed the modeling method for working process visualization, and then gave the internal structure of 3D crane model. This work designed the control logic to drive the 3D graphic elements of the visualization system, implemented the working process visualization according to the working waiting list of the crane.

Quayside Container Crane

As port cranes becoming larger, the electricity and other energy they consumed increase significantly. The research on energy saving of port cranes is increasingly hot nowadays. This paper first discusses the latest research activities on the energy saving measures of cranes. Then, taking the quayside container crane as an example, the measuring method for its energy consumption is presented and analyzed. Finally, an energy saving device for port cranes is designed to convert the motor’s no useful working energy into electricity for lighting. The design, structures and working process of this device are described in detail.

Loading And Unloading

<p><span lang="PT-BR">PT Jakarta International Container Terminal (JICT) is the largest container port in Indonesia. Currently, JICT capacity is 2.5 million TEUs (Twenty-foot Equivalent Units) per year, it continues to strive to improve international services and is supported by adequate container loading and unloading equipment. The requirement to establish common standards in different types of container port equipment and identify performance indicators to assess the performance of container handling equipment has increased. Although the Quay Container Crane (QCC) operating system may be different at each container terminal, there are similarities in its main movements, namely: Main Hoist, Trolley, Gantry, and Boom. By knowing the clock metric for each movement, it is possible to determine the Key Performance Indicator (KPI) that has been adopted and assess the performance of the Quay Container Crane (QCC). The results of the study identified that the value of MMBF (Mean Move Between Failures) decreased due to the accumulation of long-lasting heavy load operations, while the number of maintenance activities for machine parts and working hours continued to increase. Key Performance Indicator (KPI) as a management tool can guide QCC inspections and the results can provide useful insights for improving the performance of equipment and container loading and unloading operations in the future.</span></p>

Seed Metering Device

A three-dimensional discrete element method analytic model of the corn seed metering device with combination inner-cell was established based on its 3D CAD model, and the three-dimensional particle model of corn seeds was built by using the method of combination spherical particle. The working process of the corn seed metering device was simulated and analyzed by self-developed three-dimensional CAE software. It was observed that the simulative results of the seeding performance, clearing angles and dropping angles of the corn seeds well agreed with the bench test results. A novel method for studying and designing of the corn seed metering device was put forward.

The system which could be described as "trinity, seven subsystems" has realized automatic remote control of the machine working process with orientation, localization and formalization. At local place, it realized automatic position and pose online detection, automatic orientation tunneling, automatic section cutting and forming and adaptive control of cutting arm swaying speed. It was the first time that realized absolute measuring of roadheader frame position and pose error under coal mine working condition in our country which could avoid error accumulation in relative measuring and guarantee the high precision of orientation tunneling. In underground remote, it realized remote monitoring, wireless remote control and video surveillance, thus realized remote control with multiple angles, visualization and one-button control under the condition of dustiness and vibration. At any network access point on ground using mining ring network, it realized real-time monitoring and displaying of roadheader running state parameters, and realized the functions of remote fault diagnosis and alarming. The whole system has been tested many times underground. The application results show that it is stable and reliable. With the development of automation, intellectualization, and informatization and other high technology, this system will be more and more suitable for fully mechanized excavation face.

Quayside Container Crane

According to the quayside container crane, the pitch angle of the front crossbeam only can be used to classify the states of the whole crane into operating and non-operating. The Vibration Carpet Value (VCV）is presented in this paper. By means of VCV, the motor states including working and non-working can be correctly classified. Based on the classified result, by the methodology of Wavelet Packet Quantization Analysis Technique based on EMD, the real-time monitoring and evaluation of the motor condition are more correct and effective.
