Both the Siberian Crane (Leucogeranus leucogeranus) and Hooded Crane (Grus monacha) have limited population sizes and are considered endangered by domestic Chinese and international agencies. To document the current size of their respective populations and characterize their groups, between October 2012 and April 2013 we undertook fieldwork at four nature reserve areas within the Poyang Lake we...

In this paper, a study on the role of force feedback for teleoperation of industrial overhead crane is presented. Teleoperation of industrial crane was described and analyzed. We proposed several types of force feedback signals which can reduce sway motion in industrial crane. First, force feedback signal was selected and designed based on dynamic model of the system. Then, we simplified force ...

A crane is the type of machine mainly used for handling heavy loads in different industry branches: metallurgy, paper and cement industry. By the construction, cranes are divided into the overhead and gantry cranes. An overhead crane, also known as a bridge crane, is a type of crane where the hook and line mechanism runs along a horizontal beam that itself travels on the two widely separated ra...

Standardisation of crane design procedures enables designers to develop their own crane automation software for crane design applications. Since main effort and time for implementation of the crane design procedures are generally spent for interpretation and explanation of the available crane design standards, a computer-automated access to the available standards may improve speed, reliability...

of a Suspended Load with a Robotic Crane Jae Y. Lew Ahmed Khalil Dept. of Mechanical Engineering Ohio University Athens, OH 45701 USA controlled velocity source which may not hold under a heavy load. In addition, it often requires an exact model of the overall system. This paper presents a feedback control algorithm for a robotic crane carrying a suspended load. The proposed controller suppress...

Steel industry uses ladle crane as a vital material handling equipment. Design and procurement of the ladle crane is not up to the mark. Type of load, height to hoist, angle of tilt, space etc ascertains the crane specification. Mathematical analysis, taking all these factors has become an important research area. Earlier researches on ladle crane dynamics are not with so details analysis and p...

BACKGROUND The International Crane Foundation (ICF) / Endangered Wildlife Trust's (EWT) African Crane Conservation Programme has recorded 26 403 crane sightings in its database from 1978 to 2014. This sightings collection is currently ongoing and records are continuously added to the database by the EWT field staff, ICF/EWT Partnership staff, various partner organizations and private individual...

Sea states and environmental conditions are basic data for the design of marine structures. Hindcasted wave data have been applied here with the aim of identifying the proper design conditions for an innovative quay wall concept. In this paper, the results of a computational fluid dynamics model are used to optimise the new absorbing quay wall of Vlorë Harbour (Republic of Albania) and define t...

The paper studied a multi-machine and multi-task warehouse crane scheduling problem. The collision between adjacent cranes needs to be avoided in the scheduling problem. Considering the involved operation requirement and condition, a process simulation model was formulated to evaluate a candidate crane schedule through rehearsing the crane operation process. Based on the process simulation, an ...

Three species of cranes are distributed widely throughout southern Africa, but little is known about how they respond to the changes in land-use that have occurred in this region. This study assessed habitat preference of the two crane species across land-use categories of the self contained small scale commercial farms of 30 to 40 ha per household (A1), large scale commercial agriculture farms...
