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...

A U-shaped automated container terminal (ACT) has been proposed for the first time globally and adopted to construct Beibu Gulf Port ACT. In this ACT layout, double cantilevered rail crane (DCRC) simultaneously provides loading unloading services external trucks (ECTs) automatic guided vehicles (AGVs) entering yard. The DCRC a complex scheduling coupling relationship with AGV ECT, its mathemati...

There is a lack of technology innovation studies in the maritime sector focusing on developing countries. Generally, these countries present various limitations due to their own social, economic, and political contexts. Moreover, leadership support, stakeholder involvement, training, resources, financial academic support affects successful implementation technological innovation. The objective ...

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 ...

The article presents a description of the technical condition Grain Elevator building situated on port quay, which after many years operation has been decommissioned. immediate reason for cessation was change in use profile caused handling other goods at quay than bulk materials originally stored Elewator Zbożowy. work contains detailed analysis building, also taking into account functional and...

Maritime container terminals are facilities where cargo containers are transshipped between ships or between ships and land vehicles (tucks or trains). They can be automated; semi-automated or static ones depend on the type of the equipments that they contain. There are crucial resources at container terminals; the yard, cranes and the vehicles. The yard refers to the temporary storage area whe...

The paper presents a laboratory model of the 3D tower crane. The arm of the crane is approx 1.2m long and the model is approx. 1.5m heigh. The crane is equipped with three DC motors that control: the rotary movement of the tower, the movement of the trolley and up and down movement of the load. The model is equipped with an unique unit for measuring an angle position of the load. The paper cont...

The natural sway of crane payloads is detrimental to safe and efficient operation. Under certain conditions, the problem is complicated when the payloads create a double-pendulum effect. Most crane control research to date has focused on single-mode dynamics. For example, several researchers have shown that signal-mode oscillations can be greatly reduced by properly shaping the inputs to the cr...
