Belt Conveyor Idler Frame

MineAlpine idler frames, brackets, trackers and belt trainers are designed to promote low rolling resistance, excellent belt support, good belt guidance and long belt life. Fabricated from high-grade steel, all MineAlpine frames allow minimal gaps between rollers and are designed to counteract material build-up. Jig-welded for high precision, they have great structural integrity and optimal weight to loadability ratios.

Imperial (shell diameters given in mm but based on inches)

MineAlpine imperial idler frames are designed for roller series whose shell diameters, though now given in mm, are based on inches. Available in a wide range of imperial sizes for belt widths from 350-3500 mm and in various designs for different placements, troughing angles and functional demands, they can be supplied either galvanized or with a painted surface finish. MineAlpine idler frames permit great flexibility in conveyor design and idler replacement.

Metric (shell diameters in mm)

MineAlpine conveyor roller frames are manufactured to the highest tolerances utilising high quality materials and manufacturing techniques.

MineAlpine manufacture conveyor frames to suit belt widths from 400mm up to 2000mm.

Metric light duty

MineAlpine metric light duty idler frames and brackets are precision-engineered to give rigid support and long service for rollers carrying relatively light loads. Available for belt widths from 400-1000 mm and for rollers up to 108 mm in diameter, they have optimal weight to loadability ratios and can be supplied either galvanized or with a long-lasting painted surface finish.

Metric medium duty

MineAlpine metric medium-duty idler frames and brackets are precision-engineered to provide rigid support and long service for rollers in the majority of bulk solids conveying applications. Available for belt widths from 500-1600 mm and for rollers up to 159 mm in diameter, they have optimal weight to loadability ratios and can be supplied either galvanized or with a long-lasting painted surface finish.

Metric heavy duty

MineAlpine metric heavy-duty idler frames and brackets are precision-engineered to provide rigid support and long service for rollers in extremely demanding conveying applications. Available for belt widths from 650-2000 mm and for extra heavy-duty rollers up to 159 mm in diameter, they have optimal weight to loadability ratios. Like all MineAlpine idler frames, they can be supplied either galvanized or with a quality painted surface finish.

Belt trackers (belt trainers)

MineAlpine easy-to-fit belt trackers range from traditional types with side-guiding idlers to the rapid-response Belt Pilot, whose specially borne roller tilts and turns to correct the belt at the very first sign of deviation. For effective training of the return belt, we also offer Series of correctors. Mounted above the lower belt, they employ two inverted trough rollers whose width apart is steplessly adjustable.
