A fleet of Leopards — stripped, rebuilt, delivered on time.

The challenge

A fleet of Sandvik Leopard surface drills due for major work under a shut program — booms, masts and engines all at the end of their interval, on a schedule with no room to slip.

What we did

Drillspec delivered full boom and mast strip-downs and refurbishments across the fleet — feed rails, chains and wear components renewed — plus engine mid-life rebuilds and the mechanical work in between, all run to the shut schedule.

The outcome

Drillspec handed back every Leopard rebuilt and on time — strip, refurb, and back up ready to drill.
