At our Robertville, Roodepoort engineering facility, Lege Investment provides specialized heavy-equipment refurbishment that bypasses standard OEM lead times. We restore high-stress hydraulic systems, torque converters, and chassis structures.
Our team utilizes high-precision machining, custom cylinder line boring, and code welding (AWS D1.1) to ensure refurbished earthmoving equipment performs reliably under grueling African duty cycles.
"We restore heavy plant and yellow machinery to ex-works parameters, reducing lead times to zero and keeping mining and civil sites fully operational." — Engineering Workshop Director
