Augmented reality human machine interface is demonstrated in the cabin of a forest machine outdoors for the first time in real time. In this work, we propose a system setup and a real-time capable algorithm to augment the operator’s visual field with measurements from the forest machine and its environment. In the demonstration, an instrumented forestry crane and a lidar are used to model the p...

Overhead cranes are widely used in industry for transportation of heavy loads. The natural sway of crane payloads is detrimental to safe and efficient operation. However, the crane acceleration, required for motion, always induces undesirable load swing. This paper presents dynamic modelling of a 3-D overhead gantry crane system based on closed-form equations of motion. The Lagrangian method is...

The sway motion of crane can be successfully suppressed by properly shaping the reference command. Input shaping is a one type of feed-forward shaping method that is based on linear superposition. In this paper, we present the impact of double pendulum type overhead crane (DPTOC) system on the effectiveness of input shaping. An unshaped bang-bang input force is used to determine the characteris...

Assessing the safety status of cranes is an important problem. To overcome the inaccuracies and misjudgments in such assessments, this work describes a safety assessment method for cranes that combines entropy and cumulative prospect theory. Firstly, the proposed method transforms the set of evaluation indices into an evaluation vector. Secondly, a decision matrix is then constructed from the e...

When suspended payloads are moved in a material handling environment pendulum like oscillations are naturally introduced. This presents a problem any time especially when expensive and/or delicate objects are moved. In a steel industry environment objects have to be placed in tight locations after finishing up of rolling. Typically an object (rolled coil) is lifted by a hook on the end of a cab...

The red-crowned crane (Grus japonensis (Statius Müller, 1776)) is a rare and endangered species that lives in wetlands. In this study, we used variance partitioning and hierarchical partitioning methods to explore the red-crowned crane-habitat relationship at multiple scales in the Yellow River Delta Nature Reserve (YRDNR). In addition, we used habitat modeling to identify the cranes' habitat d...

U NTIL recently, very little had been published on the myology of the cranes. Fisher and Goodman (1955) d escribed in detail the myology of the Whooping Crane (Grus americana) ; they also dissected one Little Brown Crane (G. c. canadensis) . I began a myological study of the Sandhill Crane (G. canadensis tabida) at the suggestion of Dr. L. H. Walkinshaw, whose interest in the biology and taxono...

Sir,—Reference is made to Dr. Mapleson's letter (Brit. J. Anaesth., 41, 310) commenting on our improved simulator (Crane, Yates and Steen, 1968). That an active analogue is better (or, certainly, more flexible) than a passive model is not the question (Ashman, 1969) and was not the general burden of our paper. In making the obvious improvements permitted by active techniques, an analysis of the...
