MINING TYRES
stone drilling , which leads to the cause of premature tyre removal and out of service conditions . Engineered with tread grooves that allow for exceptional traction and heat dissipation , the MS412 delivers excellent traction in a variety of haul road conditions . To enable high speed operation with minimum heat buildup , MAXAM has optimised the MS412 ’ s base compound to help maximise productivity for mining operations globally .
As an innovative group , with years of expertise in the mining industry , MAXAM ’ s engineering team has designed the MS412 with a high lug-tovoid ratio for improved wear and impact defence , providing mine sites with increased protection and wear on haulage tires . Taking the existing MS402 tread pattern , MAXAM ’ s engineers took the two existing straight lines and changed them into a rounded arc . In addition , they also modified six pieces of small lugs into four bigger lugs for enhanced traction . To prevent stones on the road from trapping and resulting in deep cuts and separation , a stone ejector design was added at the area prone to stone trapping .
Some of the other features and benefits that MS412 ’ s users have cited include a relatively shallower tread depth and better heat dispersion performance ; a relatively low lug-to-void ratio with better traction plus a unique stone ejection design .
Featuring a strong all-steel casing to reduce cuts and punctures , the MS412 is engineered with increased casing durability to dominate severe hauling conditions . Similar to all large mining haulage tires in MAXAM ’ s program , the MS412 has deep tread grooves to provide cooler running tread and longer tire life .
Kal Tire TOMS and Pitcrew . ai
Built on a foundation of modern , industry-leading technology , TOMS , Kal Tire ’ s proprietary Tire and Operations Management System , was launched officially in 2018 and is now in use on more than 130 mine sites across five continents . In 2021 Kal Tire and computer vision specialist Pitcrew . ai , formed an agreement to bring mines autonomous detection of hot tyres , tyre separations and other tyre and mechanical damage any time , anywhere and without the vehicle needing to stop . Any inspection anomalies are automatically transmitted into TOMS . Pitcrew . ai leverages FLIR thermal imaging and AI technology to change the way trucking and mining vehicles are inspected . Using an AI algorithm trained on a library of thermal images , the system can spot problems in their early stages .
Christian Erdelyi , TOMS Systems and Implementation Manager , Kal Tire ’ s Mining Tire Group told IM : “ TOMS interoperability allows communication with various system and sensors
Monaflex - quick turnaround sidewall repair
Monaflex has built upon 60 years ’ industry experience to expand its range of specialist bead and sidewall repair systems . The range now covers more tyre sizes than ever before . While the popular Monaflex Custom OTR system cures repairs to sidewall , shoulder and crown in all OTR tyre sizes on the market , the company told IM that many customers are choosing to supplement their Monaflex custom system with additional workstations focusing solely on quick turnaround sidewall repairs . These extra stations use dedicated sidewall systems which provide the same inflation technology used in the standard system but incorporated into an extra quick assembly metal housing . Breaking into two parts , the inner frame is simply dropped into the tyre section and positioned with the heat pad over the repair area . Guide bars are pushed into place and locked off with pins and the system is then pressurised and brought up to temperature and the timer set . One technician can assemble the system in seconds . Monaflex now offers four sidewall only systems covering all major truck and OTR sizes . Further , the Monaflex bead repair offering is now wider than ever with a new mid-range OTR bead system supplementing the existing truck and XL OTR bead products . This expanded range is a crucial tool in the quest to improve tyre lifespans and reduce wastage due to minor bead damage .
on mine sites . The integration of sensor information into TOMS , such as thermography from Pitcrew . ai and tire pressure and temperature data from TPMS combined with AI allows Kal Tire to offer real time condition monitoring , planning and prediction . The automated TOMS workflow makes use of predefined business rules to drive certain goals . TOMS needs only under a minute from an autonomous inspection of a truck in the field to creation of a work order and team member notification , if required .”
Erdelyi said Kal Tire is running autonomous inspection stations on two mine sites in northern Canada , where it is working on refining the cold weather version . “ Both mine sites are supporting the innovative initiative and going out of their way to integrate the autonomous inspection station into the mine plan and traffic management . In Canada , we are also upgrading our mobile weight scale system to integrate a mobile Pitcrew inspection station in order to use this technology on trucks taking part in weight studies . This allows customers that do not have their own autonomous inspection station to get an insight on their fleet during weight study events .” In addition , Kal Tire is operating an inspection station on a mine in Chile . Currently it is also mobilising inspection stations to Mozambique , Colombia , and Australia .
Where on the active minesite is the best place to position Pitcrew . ai technology in terms of performance ? “ The location is driven by the use case . The inspection station can serve to monitor trucks entering fuel and maintenance areas to alert when there are trucks with hot or severe damaged tires to enter those areas . Haul roads leading to fuel farms provide good inspection results . For continuous inspections locations with high traffic and low speeds as ROM pads , crusher and breaker areas are great to position as well if sufficient dust controls are in place . The greater the frequency for a truck to be scanned and inspected , the better . The business rules in TOMS ensure work orders are only created when the condition of the truck requires it .”
And how does the technology application vary by site ? “ Each mine site has specific goals and targets depending on the operational condition and circumstances , which are defined and agreed upon mobilisation . At one mine site , Kal Tire has to call down trucks for regular inspections , and with the deployment of an autonomous inspection station the goal was set to reduce that downtime by 20 % per month , allowing more productive time for trucks , keeping the same level of inspection quality and safety . Another goal that was set was to monitor and track at least 70 % of all tyres under condition monitoring . That customer operates different fuel farms and aims now to direct all traffic with trucks that have tyres under condition monitoring to the fuel farm that is equipped with the autonomous inspection station . On all sites Kal Tire is tracking with its Service Delivery Report in Power Bi as to how we are performing against those targets .”
On comparing Pitcrew . ai with TPMS systems he stated : “ TPMS are great go / no go tools enabling the Kal Tire site manager or mine dispatch to interfere when necessary , but TPMS systems cannot give us information on the condition of tires . Pitcrew . ai inspection stations provide eyes on the outside of tyres , showing us damages where the tyre is exposed such as cuts , cut separation , missing lugs , and others . It also helps us to find sealed or hidden from the eye problems such as hot spots in tread and sidewall . Combining both sensors TPMS and Pitcrew . ai allows a 360 view on our customers
tyres .”
