Parrahub 10m diameter LTBM

The picks being twice the size will absorb more heat allowing far more pick life.-----------------Designed to work in 10m diameter tunnels and could easily be used with 100t shuttle cars making 250m pillars for 250kph subways because the flat top surface will allow roof support to be done while shuttle car is transporting muck to conveyor belt.
