Armored Face Conveyor

PFHD

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.

Additional Information

Special Features for Heavy Duty Applications

NEW PROFILE

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.

NEW POCKET DESIGN

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.

CORROSION PROTECTION

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.

IMPROVED MAINTENANCE DOOR

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.
