JOY BROADBAND long life chain provides proven extended wear resistance without detriment to chain weight and conveying characteristics, delivering new levels of chain conveying efficiency and reduced operating cost. First installed in 2004, over the last five years the chain has conveyed over 80 million tonne on AFC & BSL applications in high productivity longwall installations operating in many major markets.
With improved chain life, this innovative product is consistently pushing the boundaries on extended chain life, with operators planning larger block sizes. JOY BROADBAND long life chain provides the greatest opportunities to longwall operators planning their future developments or upgrade requirements.
Lower Line Pan Profile
JOY BROADBAND long life chain provides the lowest longwall equipment per kW of installed power across the range of high efficiency longwalls. Its small envelope size facilitates lowest height linepans providing valuable height savings in low seam applications, improves shearer tunnel clearances and conveyor loading ability, and adds flexibility to the haulage track position.
Greater Installed Power
With the Joy 3000 series gearboxes, JOY BROADBAND long life chain provides for the largest longwall operations and highest installed powers. A gateway to improved productivity, through increased hourly capacity, longer face lengths also reduce roadway development time and costs, thus providing a safer longwall operation.
