Joy walking miner

Joy walking miner

A continuous miner with a walking mechanism instead of crawler tracks. The walking mechanism was adopted to make the machine suitable for thin seams. The lowest crawler-track-mounted machine can operate in a minimum seam height of 4 ft (1.2 m), whereas the walking type can work in a 2.5-ft (0.76-m) seam.
