Dump trucks are widely used in the construction industry. When sand is discharged from a dump truck bed, friction with bed causes to remain on bed. Therefore, it desirable develop technology adhere low-friction fluororesin steel plates of This study develops technique for directly joining dissimilar materials, namely and polytetrafluoroethylene (PTFE), using one-sided seam welding investigates ...

In order to improve fuzzy fatigue reliability and make weight reduction of A-type frame in an electric mining dump truck considering multi-source uncertainties from design, manufacturing use stage, a multi-objectives optimization method based on the interval theory was proposed this paper. The thickness four steel plates welded regarded as certain design variables, while elastic modulus density...

The Overburden of waste and uneconomic mineralized rock is required to be removed to mine the useful mineral resource in a surface mining operation. In this process a dump is formed by casting the waste material and dumping it in nearby area. The dump so formed is known as mine waste dump. Waste dump may be classified as internal and external dump. External dump is created outside the pit where...

Purpose.The aim of the study is to develop recommendations for reducing probability accidents during transportation rock by dump trucks based on analysis consequences changes in psycho-physiological states driver. Methods. The used method “Hazard and operability studies” “Failure Mode Effects Analysis” including organizational, logical mathematical, statistical procedures aimed at obtaining exp...

Reducing the costs of rock transportation in mining is one most important tasks. One reserves for solving this issue a more complete use service life quarry dump trucks tires, since their operation takes place heavy and climatic conditions significantly reduces tires. The tires depends on many factors: speed movement, compliance with recommended air pressure tire, ambient temperature, but main ...
