During this season, due to high running costs of the slewing loader,an exercise wascarriedout to compare the slewing loader and the hi-capacity Bell loaders. The slewing loader in use at the time was the model with high lift boom mounted on a Ford 6600, modified with a Brockhouse torque converter. The comparison revealed that, under the conditions obtaining at Mgayi section, the Bell loader was...

Problem. The T-156B hinge frame of the loader, which is an upgraded agricultural tractor, during work operations creates loads for it was not designed. Such lead to breakdowns and further shorten life entire machine. basic element around machine built. loader that had just been removed from conveyor did have built-in durability reliability. While designing a road construction machine, account f...

Purpose. To substantiate a rational schedule for the combined dragline-truck operation taking into consideration coefficient of mining in context pit. Methodology. Mathematical and graphical modeling was involved while determining concentration pit as well feasibility analysis to select procedure scheme dragline operation. Findings. Recommendations selection operation, truck loading Motronivsko...

Optimizing the configuration of a wheel loader to customer needs can lead to a significant increase in efficiency with respect to fuel economy, cost, component dimensioning etc. Experience show that even modest customer adaptation can save around 20% of fuel cost. A key motivator for this work is that wheel loader manufacturers in general does not have full information about customer usage of t...

The efficient and safe movement of freight is one of the important goals of urban transportation systems and vital to not only the local economy, but nationally as well. Given the importance of the freight transportation system, opportunities to utilize state of the art Intelligent Transportation Systems (ITS) technologies are increasing to improve the operation of the existing infrastructure t...

Articulated wheel loaders used in the construction industry are heavy vehicles and have poor stability and a high rate of accidents because of the unpredictable changes of their body posture, mass and centroid position in complex operation environments. This paper presents a novel distributed multi-sensor system for real-time attitude estimation and stability measurement of articulated wheel lo...

VMT and vehicle classification are vital inputs in the design and operation of an efficient transportation infrastructure system. In particular, heavytruck VMT is important as the number of heavy vehicles on a road affects traffic operations, safety, and pavement performance. Research has revealed that current methods used in the estimation of heavy-truck VMT are often less accurate than those ...

Absfmcf-This paper describec the implementation of an autonomous navigation system onto a 30 tonne Load-Haul. Dump truck. The control architecture is based on a robust reactive wall-following behaviour. To make it purposeful we provide driving hints derived from an approximate nodal. map. For most of the time, the vehicle is driven with weak localization (odometry). This need only be improved a...

This paper proposes a micro-simulation model for urban freight movement, in which the behavior of freight agents and their relationship in supply chains are incorporated. The proposed model is a modification of the traditional four-step approach in that it considers the behavior of each freight agent individually. This paper covers three of the four steps of the traditional approach, including ...

One of the most important steps in development of a new truck chassis is the prediction of fatigue life span and durability loading of the chassis frame. The age of many truck chassis in Malaysia are of more than 20 years and there is always a question arising whether the chassis is still safe to use. Thus, fatigue study and life prediction on the chassis is necessary in order to verify the saf...
