This paper pertains to advanced automation of the load transfer process using overhead cranes. Overhead cranes are widely used in various areas of industry, including manufacturing, construction, shipping, etc. Load transfer operations using overhead cranes have to be performed fast and safely. As such, these operations are handled by expert operators however, the demand for an automatic consis...

This paper studies the simultaneous reshuffle and yard crane scheduling problem in the yard of container terminals, which is one of the key logistics problems affecting the operation efficiency in container terminals. Although the reshuffle scheduling problem has received many research attention due to its importance, the problem without considering yard crane is not very practical, which is be...

The mobile crane simulator is a project sponsored by Employment and Vocational Training Administration, Council of Labor Affair, Executive Yuan, Taiwan, to build a safe device for training and licensing. This paper presents the principle and mechanism to build a high-fidelity interactive visual simulator on a cluster of PCs. The implemented mobile crane simulator uses the peer-to-peer architect...

In this paper, a new fuzzy anti-swing control scheme is proposed for a three-dimensional overhead crane. The proposed control consists of a position servo control and a fuzzy-logic control. The position servo control is used to control crane position and rope length, and the fuzzy-logic control is used to suppress load swing. The proposed control guarantees accurate control of crane position an...

Quay crane allocation is one of the most important scheduling plans in the container terminal. A large of production data is stored in the database of the terminal. This paper utilizes the method of data mining to analyze the problem of quay crane allocation by using these data. From the mining, valuable information has been gotten from the database. The paper chooses the fuzzy cmeans cluster a...

The complex, dynamic, and continually changing nature of construction work has been recognized as an important contributor to the high rates of injuries and fatalities in the industry. Cranes are a central component of many construction operations and are associated with a large fraction of construction deaths; in fact, estimates suggest that cranes are involved in up to one-third of all constr...

Crane Division, Naval Surface Warfare Center, Crane Crane's comprehensive pollution prevention program emphasizes planning, employee education, innovation and incentives. One of Crane's primary goals is to move the facility from a pollution control mindset to a pollution prevention ethic through its Corporate Environmental Policy Statement, environmental management system and educational tools ...

The Dynamics characteristic of Tower Crane is complicated under the wind excitation which complicates the wind-induced vibration response analysis. The random wind-induced response analysis of tower crane is presented based on finite element method and Virtual Excitation Method. The pulsating wind loads are changed into multiple-point correlation stationary excitation. This papers uses Davenpor...

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...

While the microbial water quality in the Platte River is seasonally impacted by excreta from migrating cranes, there are no methods available to study crane fecal contamination. Here we characterized microbial populations in crane feces using phylogenetic analysis of 16S rRNA gene fecal clone libraries. Using these sequences, a novel crane quantitative PCR (Crane1) assay was developed, and its ...
