Mackay has designed and developed many replacement rolling stock primary suspension elements for Australian passenger fleets to improve ride and durability.
Our engineering design facilities include Kinematic modeling and Fluid Coupled Finite Element Modelling placing our design capability at the forefront in the region. Mackay’s ability to re-engineer and manufacture primary suspensions allows fleet operators local service, support, and smaller volumes with production batch sizes as low as 96 pieces (3 car set).
Mackay has designed and manufactured both original equipment and replacement locomotive rolling stock primary suspension elements. Re-engineering has been undertaken to allow for an increase in locomotive weight during upgrade whilst
maintaining unchanged fitment. Mackay provides re-engineered elements to address in-service lifetime issues with original equipment components.
