Automated rough mine road detection

first_imgModular Mining Systems says to respond properly to rough roads, awareness is essential. Operators recognise bad road segments, and they can use an option to indicate such locations via manual input – but this has safety concerns for operators and reliability issues for management. In response to this dilemma, the company has released the Road Roughness module, consisting of a rugged accelerometer that can be installed on any haul truck to solve the detection problem. The accelerometer is an effective, low-maintenance and purpose-built device that reliably detects road conditions without the need for operator input.Continuing with news that could not be included in the published surface haul trucks feature, the company explains, “Some may say that the problem of detecting road conditions has long been solved by payload sensors. However, onboard payload measuring systems are not available on all equipment and few mines have all of their trucks equipped with these systems,” according to Modular. “Though open pits have technology they can use, there are still issues with detection systems. More importantly, few tools exist to adequately respond to detected events.”As with any on-board sensor, a fleet and/or maintenance management system is also required to transform sensor readings into meaningful events and to assign resources that can address the problem. The Dispatch system’s Auxiliary Task module, for example, provides a production cycle for auxiliary equipment that differentiates the time to ‘travel to a workplace’ from the time spent ‘performing work’. A Road Work task type can be assigned to graders and/or other road dressing equipment, which appears in a schedule with the equipment’s other tasks. Dispatchers, shift supervisors, and upper level management can allocate tasks based on priority, considering the travel distance of each grader before assigning the work.Providing auxiliary operators with on-board software tools is critical to improving response time. Work performed by auxiliary equipment is different in nature from haulage. Auxiliary work should be managed holistically – there are many factors to consider before a grader operator is assigned to fix a detected rough road section. Technical details, such as the size of the job, location, travel time, and estimated repair time need to be evaluated. Higher level perspectives of all the work required by that machine should be considered, such as the possibility that an operator might need to operate another piece of equipment in that same shift. The right dispatching technology should provide equipment operators and other personnel with the means to account for all of these factors, and the ability to address them in real time.Closing the loop in rough road detection using automated technology, without increasing manpower requirements, requires a substantial IT infrastructure: sensors on haul trucks, fleet management hardware on auxiliary units, wireless communication networks, and experienced control room staff. Most importantly, all software and hardware systems must be architected to work together. This list of requirements may seem high, but by leveraging the investment already made in a fleet management system, such as Modular’s Dispatch system, real productivity gains can be realised with relatively small additional investment. Integrated solutions can address complex problems like haul road maintenance, smoothing the way to increased production.last_img read more

FederalMogul to launch new engine components and technologies at Bauma

first_imgFederal-Mogul Motorparts is to launch several new FP Diesel® technologies at Bauma in Munich between April 11-17; as well as displaying the brand’s extended portfolio, including pistons, connecting rod bearings and turbocharger and head gaskets. The company says the products have been developed to meet the increasingly demanding conditions of modern diesel engines. Mining and construction vehicle engine manufacturers have made tremendous progress in recent years to reduce emissions, while increasing overall engine power and durability.”The continuous development of individual engine components is critical in order to withstand the higher combustion pressures and temperatures involved with these highly efficient engines. FP Diesel has expanded its range of turbocharger gaskets to include the brands patented high temperature alloy (HTA®) multi-layer steel construction. “The technology ensures the gaskets are reliable and long-lasting at operating temperatures of up to 1,000°C, even with high temperature fluctuations and high alternating mechanical loads,” explained Frank Piojda, Director, Off-Highway/Heavy-Duty, EMEA, Federal-Mogul Motorparts.In addition to the turbocharger gaskets, FP Diesel is presenting its expanded range of the 7-layer ML7 cylinder head gasket for Caterpillar, Cummins and Detroit diesel engines, which is used mainly in mining applications. The gaskets consist of multi-layered steel cores embedded in perforated graphite composite layers, as well as a secondary sealing layer. They are designed to withstand the significantly higher combustion pressures and temperatures of high-performance diesel engines.FP Diesel is also launching its friction-welded POWERFORGED® pistons, which are already used by many leading commercial vehicle and engine manufacturers and are now also available in the aftermarket for Cummins ISX and QSX engines. The patented one-piece, forged steel technology provides the pistons with improved structural strength. The latest generation has a unique double-band piston skirt, which helps to considerably reduce weight and skirt surface by up to 40%. The result is a reduction in friction by up to 17%, providing increased efficiency and lower fuel consumption.In addition to the gaskets and pistons, FP Diesel is presenting its improved connecting rod bearings for construction diesel engines, such as the Caterpillar 3500er series. The lead-free bearings consist of a high-strength material called G-188, which has a pliable running surface alloy that changes its wear resistance and load carrying capacity to the load and temperature conditions in the specific application. The result is a more durable bearing compared to conventional tri-metal aluminum bearings. “Bauma is the most important fair for FP Diesel and offers the perfect stage to present our latest developments to customers and other interested parties,” added Piojda. “We look forward to presenting a portfolio which offers solutions to the audience’s latest powertrain challenges.”last_img read more
