The chain gang: the battle against corrosion

Tsubaki uses alloy-grade steels which are heat-treated to precise specifications and assembled with the heavy press-fits necessary to withstand the punishment of today's more powerful, high production mining equipment Tsubaki uses alloy-grade steels which are heat-treated to precise specifications and assembled with the heavy press-fits necessary to withstand the punishment of today's more powerful, high production mining equipment
The complete line of mining chains includes Feeder Breaker Chain and Super Shuttle Car Chain, as well as various chains which are widely used in drill rigs, rotary breakers, face/roof drilling, reclaimers, under cutters, preparation plants, continuous miners, roof support machines and continuous haulage systems The complete line of mining chains includes Feeder Breaker Chain and Super Shuttle Car Chain, as well as various chains which are widely used in drill rigs, rotary breakers, face/roof drilling, reclaimers, under cutters, preparation plants, continuous miners, roof support machines and continuous haulage systems

A surface treatment provides superior corrosion resistance for chain and sprockets used in ultra tough conditions

As the extraction and processing of the raw material is done in the most demanding of environments, components on the machinery in these applications need to excel in tough conditions. 

For surface mining Tsubaki offers a wide variety of tried and tested heavy duty roller chains, conveyor chains, reclaimer chains, engineering class sprockets, back stops, electro mechanic actuators and protection devices for use on equipment or in plants such as drill rigs, feeder breakers, rotary breakers, mining shovels and conveyors.

* Underground mining: In this extreme environment shock loads are high and chain and/or sprocket failures can take hours to repair. Thus, efficient and reliable extraction can mean the difference between profit or loss. In this environment, all the equipment must be as reliable as possible and provide maximum performance with minimal downtime. For these harsh applications Tsubaki offers its specially designed shuttle car chains, heavy duty chains, and chains for continuous miners.

* Speciality mining products: Tsubaki has also designed and manufactured its own line of top-grade carbon steel, alloy, and stainless steel sprockets for use with its chains to maximise reliability in mining applications. It has developed a series of Back Stops, Cam Clutches and Power Lock devices which can be utilised in various applications and industries to help improve safety on the mining site. Cam Clutches and Back Stops allow freewheeling or overrunning in one direction, and driving or backstopping in the other, protecting both the equipment and employees, while Power Locks eliminate backlash damage to keyways from heavy loads.

Tsubaki has developed a surface treatment for its chain and sprockets that provides superior corrosion resistance and significantly extends the service life of the components.  The mechanical plating system forms a lasting bond to the steel and is recommended for use on any equipment that may be exposed to external conditions, chemicals or salt water.
