  • Easy to fit: No special qualifications required to weld. As an alternative to welding, studs can be attached on request.
  • Flexibility: Bradken can supply block products for attachment in the field as required, or they can be pre-attached to equipment at one of Bradken’s engineering workshops.
  • Adaptability: Bradken’s block products are available in a wide range of dimensions and can be adapted to suit a wide range of operating conditions.

 

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.
