The HBT PF HD line pan for armored face conveyors is specially designed for heavy-duty longwall applications with very demanding conditions. The design is based on actual customer requirements and represents the most robust and reliable HBT line pan available, with an increased wear backup. The PF HD line pan lasts up to two times the life of corresponding PF5 or PF6 pans.
Dogbone Breaking Strength
4500 kN (505.82 tonf)
Shear Strength
> 6000 kN (> 674.43 tonf)
Conveying Capacity
up to 0.85 m2 (9.15 ft2)
The mono pan design with the new heavy-duty profile features an increased wear backup and flight bar overlap, as well as reduced height outside and improved welding connections. The thickness of the deck plate is 70 mm (2¾ inch minimum to 3 inches maximum) or 60 mm (2¼ inch minimum to 2½ inch maximum). The bottom plate thickness is 30 mm (1¼ inch) or 40 mm (1½ inch minimum to 1¾ inch maximum).
The PF HD line pan is available in the widths 1062, 1162, 1262 and 1362 mm (41.81, 45.75, 49.69 and 53.62 inches).

*Depending on chain size
**Depending on shearer
The newly designed sigma profile features an additional 10 mm (0.39 inch) thickness for very long service life. This extra thickness also ensures an increased flight bar overlap for enhanced guidance on the long run. The special shape of the profile, with a beveled edge on the outer contour at the face side, optimizes loading performance. A new full-penetration welding geometry ensures a strong connection between profile and deck plate, even at maximum wear.
A new optimized dogbone pocket design uses a closed pocket shape with increased longitudinal load-absorbing welds. The pocket features a symmetrical shape with a reinforced cross section to withstand the strong forces of shearer passage and dogbone pulling forces.
Optional sacrificial anodes can be installed in the dogbone pocket area to reduce corrosion in high-stress areas. This ensures maximum corrosion protection for the high stress parts of the pocket and the dogbone.
The PF HD line pan features the maintenance door functionality used on other PF line pans; however, it has been adjusted to resist high wear. The improved design of the face side area features a threaded slot to lift the maintenance door, which is hidden outside of the wear area. It is sealed to prevent fine coal from entering the bottom race.
