Are trucks achieving predicted speed on grades? Are trucks cycling in predicted cycle times? Are truck wait times at the loader in the predicted range? A Caterpillar exclusive monitoring tool that uses on-board pressure sensors, RAC monitors and logs haul road severity to increase truck life and reduce cost/ton.
allows you to measure the steepness of a grade by sighting the instrument down the grade, parallel to the surface of the road, and aligning a leveling bubble. If you think a more detailed analysis of the haul road situation is called for, discuss the situation with your supervisor.
Haul road grades compatible with the capabilities of the equipment using them. Steep grades have been a factor in haul-age accidents. Traffic signs to control traffic flow and . to provide vehicle operators with infor-mation (such as speed limits, grades, and traffic patterns) to help ensure safe opera-tion. Roadways that are inspected, main-
The paper describes the present state of the art regarding the design, and construction of Haul Roads for off-highway mining equipment and outlines the philosoohy that BHP Engineering {BHPE)
Haul Road Analysis - Maptek
Road or wall conversion grade - angle needed in the interpolation spacing to detect a change from haul road to a wall or to a bund. Toe convergence rises - is the number of subsequent upward points needed to create a toe. Crest convergence falls - is the number of subsequent downward points needed to create a crest.
(PDF) Guidelines for Mine Haul Road Design - ResearchGate
2001年1月1日 · Haul roads were constructed with haul trucks to deliver (and compact) materials, graders and dozers to spread the material in appropriate lift heights, and smooth drum vibratory compactors.
Haul Productivity Optimization: An Assessment of the Optimal Road Grade
2019年2月22日 · The assessment performed in this work showed that haul road grades are relevant geometric parameters and deserve attention in determining the pit geometry. The models developed to optimize haul road grades are an important complement for the analysis of the productivity and costs.
Predict the tire pressures needed to allow Pope & Talbot’s trucks to haul, unassisted, at least typical highway-size payloads (34 000 kg) on adverse grades up to 16%. Validate the tractive analysis theory on an actual hauling trial.
Mining trucks, also called haul trucks or o -road trucks, haul the ore or waste material from the loader to a dumpsite. More commonly, these vary from 36 tons to 315 tons. The size and cost of operating mining trucks is directly proportional to its tray capacity, while the speed at which the truck can travel is inversely proportional to its ...
Cost-Effective Grading of Haul Roads in South Africa
a grade of around 8% to 10% is ideal; a road width of approximately three times that of your haul trucks is recommended; this prevents the vehicles from knocking over berms and scattering rocks and gradient onto the surface. The most efficient haul roads are constructed from a blasted rock base and a durable, coarse material.
