Applications of Block Products

Bradken’s block products can be strategically placed on equipment before it enters service to prolong life in high wear locations. They can also be welded onto equipment during service to rectify wear in unexpected, localised trouble areas.


Duablock® wear bars offer excellent protection when used as tumble bars or when configured to form a rock-box. They are also used to provide protection on heavy earth moving machinery.



Duabutton® blocks are extensively used on heavy earth moving equipment, particularly on mining and construction buckets and shovels.



Microledge® blocks are attached to chutes to form rock boxes, which virtually eliminates wear to the chute structure.



Chokblock® bars are unique block products that can be formed and welded onto flat or curved surfaces. This allows Chokblocks to be used on a range of fixed plant and mobile equipment such as buckets and chute liners.



Skidblock® pads are used extensively to provide strategic protection on heavy earth moving equipment, particularly on mining and construction buckets and shovels.



Duatrap® liners are used to create a rock-box effect on fixed plant applications such as chutes and impact walls.



Grizzlybar cappings are used to protect grizzly fingers.



Duanut® blocks allow protection of nuts or bolt heads. The Duanut also offers flexible attachment options with internal and external welding possible.


 Skirt Liner  

Skirt Liners are used to assist in centrally loading conveyed material on the conveyor belt, containing spillage, and controlling dust at the transfer.
