Bosch Rexroth South Africa Group companies overcome lockdown challenges to supply essential hydraulic services

Written by
The cylinder repair work was executed during South Africa’s national Covid-19 lockdown to minimise downtime at the plant.

Hytec Secunda was tasked with overseeing the urgent repair of two hydraulic cylinders for a large regional customer.

Working with fellow Bosch Rexroth South Africa Group company Hytec Engineering, the cylinders were delivered and installed in just 10 days, despite the challenges of South Africa’s nationwide Covid-19 lockdown over the period, ensuring downtime on these important plant functions was kept to a minimum.

Hytec Secunda was responsible for all site work, as well as transport of the cylinders between the plant and Hytec Engineering’s cylinder manufactory in Johannesburg.

There, the 250/115 x 1060 FF filter press cylinder was overhauled, including stripping, inspection, refurbishment, honing and testing. This cylinder works in a filter press that solidifies gunk and separates the liquid from the solids for further processing.

 Hytec Engineering also manufactured a new cylinder for a flopper gate. An older cylinder is also currently being repaired that will be used as the backup cylinder for this equipment in the future.

“Repairing a hydraulic cylinder can be far more cost-effective than purchasing a new one,” explains Andre Lindeque, Hytec Engineering’s General Manager. “The challenge was to rapidly coordinate the service of this equipment in line with the lockdown restrictions to minimise downtime of these essential plant processes.”

Hytec Engineering provides end-to-end hydraulic cylinders services for mines and industries across sub-Saharan Africa.
