Intended for horizontal and longitudinal use in inclined corridors up to 14º.
With transverse inclination of the excavation up to 12º, transport is permissible with 2 additional side struts (sidewall struts) mounted to special grips in the spreader beam.
PAT-1 allows to avoid problems related to:
- Repeating displacement of the longwall drives with face/wall advance
- Repeating movement of beam stage loaders with face/wall advance
- Transportation of mining machinery heavy elements to the assembly site
- Transportation of transformer stations and pumping sets
- Transportation of mechanized casings, frames and drive units of scraper conveyors
- Transportation of the above-mentioned equipment, elements and machine parts after completion of underground work..
