Solved: Heavy-Duty Excavator Failure for an Australian Mine
Challenge
A mining client in Western Australia faced frequent cylinder failures due to abrasive dust and high shock loads, causing costly downtime.
Solution
TOPA engineers analyzed the failed units and proposed a custom design featuring hardened chrome plating, upgraded Hallite wiper seals, and reinforced welding at the trunnion mount.
Result
The new cylinders extended the service life by 300%, significantly reducing maintenance costs. This success solidified TOPA as their primary supplier.
Trusted by Industry Professionals
"We shifted our procurement to TOPA three years ago to cut costs, but we stayed for the quality. Their team caught a design error in our drawings before production, saving us thousands. The cylinders arrive well-packed and the chrome finish is consistently excellent."
— Mark T., Procurement Manager (Construction Equipment OEM, USA)"Finding a reliable supplier for custom agricultural cylinders was difficult until we found TOPA. The communication is professional, and they actually stand behind their warranty."
