MINE MAINTENANCE
Martin Engineering recently announced a conveyor belt cleaner position indicator that , it claims , monitors the blade , tracking and reporting remaining service life , helping reduce the risk that comes with manual conveyor inspections .
The Martin N2 ® Position Indicator ( PI ) monitors primary belt cleaner blades , notifying Martin Engineering service technicians and plant operations personnel when re-tensioning or replacement is required and / or when abnormal conditions occur . The PI can be part of a new installation or directly retrofitted to existing mainframes that use the company ’ s replacement blades , with managers and service technicians , alike , able to quickly access information on any networked cleaner via a mobile device .
With some 1,000 operating systems currently in service and installations continuing daily , the technology has been embraced by bulk material handlers in a wide range of industries and applications , according to Martin Engineering .
The solution was designed in-house by the engineering team at the company ’ s Center For Innovation and is produced solely in companyowned facilities to ensure the highest standards for quality control . In fact , the firm also engineered and built the proprietary equipment used to manufacture the new devices .
Martin Engineering offers the equipment , monitoring service and batteries free of charge to qualifying customers . It will also support the PI components and provide customer alerts without cost as needed , with mainframes and tensioners replaced free for users of Martin belt cleaner blades , the company says .
Position Indicators can be mounted anywhere from 3-800 m from the cellular gateway and the robust , sealed construction means it is virtually immune from damage , according to the company .
Up to 200 units can be monitored by a single gateway connected to the internet , usually located at the highest point in the plant where the cell signal is strongest . The system does not require a cellular line for each PI , instead communicating via radio frequency from each sensor to the gateway .
“ Operating independently of any plant communications infrastructure , the small physical size and low power requirements deliver a projected battery life of two years ,” the company says . “ The self-contained model was developed by Martin Engineering in order to minimise the dependency on in-plant resources . Only the gateway requires a constant 110 V power point .”
The device eliminates the need for manual inspections by giving technicians precise information , delivering critical real-time intelligence and reducing exposure to moving conveyors , improving both efficiency and safety , Martin Engineering claims . Maintenance
The CBGuard Life Extender provides all-in-one radiographic conveyor belt monitoring , continuous real-time analysis and reporting , and detection and live marking of all defects / damages associated with splice failures , among other things , the company says , with “ every cubic millimetre of the conveyor belt analysed ”
planning , meanwhile , is simplified by having detailed information available on demand , allowing service personnel to deliver and install replacement wear parts during scheduled outages .
Martin Engineering Global Conveyor Products Director , Chris Schmelzer , said : “ Belt cleaner inspection time is basically eliminated as maintenance personnel no longer need to physically view the cleaner to determine the tension or wear status . It also reduces the time workers need to spend near the moving conveyor , helping to minimise the potential for accidents .”
