Solve Reclaimer Pantograph Cracking
Adra identified cracks at the connection of the pantograph structure to the luffing cylinders during a routine inspection.
The machine OEM proposed a modified gusset profile and Adra analysed the repair original design and repair to verify the changes. The analysis predicted the cracking, confirming it was the result of a design flaw. Adra delivered a modified gusset designed to lower the stress concentration, provide a uniform stress distribution and improve the load transfer from the gusset to the pantograph mounting beam.
Through Adra’s advocacy the OEM implemented the repair under warranty using the improved gusset design.
