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...

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...

A gantry crane at the Savannah River Technology Center was retrofitted with an Input Shaping controller. The controller intercepts the operator’s pendant commands and modifies them in real time so that the crane is moved without residual sway in the suspended load. Mechanical components on the crane were modified to make the crane suitable for the anti-sway algorithm. This paper will describe t...

Many procedures in the development process of crane cabins today are still based on the specific experience of manufacturers and historical guidelines. It is not surprising that they fail to meet the needs of a large proportion of operators. Accordingly, the need for more objective, theoretically justified and consistent models, that will minimize crane operators’ biomechanical and visual probl...

In an accompanying paper submitted concurrently to this conference, we present our first complete version of a generic and modular software framework for intelligent computer-automated product design. The framework has been implemented with a client-server software architecture that automates the design of offshore cranes. The framework was demonstrated by means of a case study where we used a ...
