Our Process
Pressure Test & Leak Detection
We pressure-test the entire hydraulic circuit to pinpoint every leak and measure system pressure against manufacturer specifications.
Component Rebuild or Replacement
Cylinders, valves and pumps are rebuilt with OEM seals. Where damage is beyond repair, we supply quality replacement parts.
Certification & Load Test
Full load test at rated capacity before handover, with a written service record and load certification.
Frequently Asked Questions
How long does hydraulic repair take?
A cylinder seal kit replacement is typically done in one day. A full hydraulic system overhaul — including mast, valves and pump — usually takes 2–3 working days. We provide a written timeline and quote before starting.
When should forks be replaced rather than repaired?
Forks should be replaced when they show cracks, surface fractures, a bend angle exceeding 3 degrees, or wear reducing blade thickness by more than 10% from the original. Our inspections follow SANS 10396 guidelines and we advise you transparently.
