A new crane design, labeled ”SpiderCrane”, is proposed to handle fast load displacements. Its main particularity is the absence of heavy mobile components. The system beeing underactuated, its control is challenging. Hence, as a step towards easier and more efficient control, this paper proposes a dynamic model and investigates the two control-relevant properties of flatness and observability. ...

The paper presents a dynamic model illustrating the swing of mobile machine on wheeled chassis equipped with loader crane and anchor outriggers during loading unloading operations. regards interaction effect outrigger anchoring device weak soil within system “load – devices soil”. Possible variants single multiple step compaction changes in its deformation characteristics area implementation ar...

The APMINUD is a mechanical tool designed to safely detonate antipersonnel landmines as part of a peace time clearance operation. The APMINUD consists of a mobile blast and fragment containment shell, with a mechanical striker inside. It can be used in conjunction with a shielded, all terrain vehicle with crane. The vehicle is used to move and lower the shell over a marked mine location. The in...

Hydraulic machinery is a mechatronic system that widely used in various industries such as the mining, forest, and construction industries. Computer simulation of hydraulic crucial because it can be to affect almost everything from operational activities designs features. The objective this article monolithically couple multibody dynamics actuators by utilizing semianalytical numerical methods ...

Most of the soil conditions in Kubu Raya Regency are soft and peat with low carrying capacity potential for foundation subsidence, especially high-rise buildings. Using a Hydraulic Static Pile Driver 120 tons Crane Mounted Drop Hammer 35 is an alternative to driving deep foundations on soft/peat soils. The purpose this study was conduct comparative productivity, costs, risk aspects, occupationa...

This paper describes a unified approach to modeling and simulation of hydraulic systems using bond graphs. Unlike the others, the causalities are not applied in bond graph settings. This leads that mathematical model is generated in the form of differential algebraic equation (DAEs) and solved as such by suitable solver. Bond graph model of simple hydraulic system has developed using program Bo...

this paper proposes a simple but efficient technique to control 3d overhead crane. load musttrack a desired path and not sway more than a reasonable range.the proposed method uses pidcontrol for trolley to track the desired path and fuzzy control compensation to eliminate the loadswing. only the projection of swing angle is applied to design the fuzzy controller. no plantinformation of crane is...

This study presents a steel container crane movement analysis and assessment based on structural health monitoring (SHM). The accelerometers are used to monitor the dynamic crane behavior and a 3-D finite element model (FEM) was designed to express the static displacement of the crane under the different load cases. The multi-input single-output nonlinear autoregressive neural network with exte...

This article presents the design system for high efficiency gantry crane system using elevator and conveyor system. The basic concept for the proposed gantry crane system can be used with modification of the classical gantry crane instead of changing lots of them. However, the proposed crane system can reduce the cycle time more than the classical gantry crane. The high efficiency gantry crane ...
