Tuyere machine

Clarks Mining have manufactured two Tuyere machines for use at the Port Kembla Steel Works. The machine is LPG powered and is designed to install and remove Tuyeres from the blast furnace. The machine’s undercarriage design was based on the Clark air powered drill rig but has a shorter wheel base and polyurethane coated track pads.
