Latest Heavy Vehicle Projects:

From custom show truck builds, on site breakdowns to hydraulic repair – we have you covered!

Historic Truck Build

This truck was brought to us after being sunk in mud for 20+ years. Full chassis replacement, full running gear rebuild, engine/gearbox rebuild, rooftop A/C and some custom additions – this was a true chassis up restoration.

Hydraulic Pump Retro Fit

This excavator had an obsolete and now faulty hydraulic pump. We matched a readily available unit to the machine and custom machined new bellhousing adaptors to ensure perfect fitup. After an entire hydraulic system flush the machine was back in operation.

Track Gear Overhaul

HiRok performed a complete teardown on the track gear of this 70t rig replacing all rollers, idlers, rebuilding final drives and painting the undercarriage prior to fitting all new chains and grouser plates.
