On all pulleys over 16" in diameter, CCI uses an oversized pipe end design to reduce the overall wing height. This design helps eliminate the tendency for wings to fold on contact with large rocks or other material.
Mine Duty Wing Material
CCI also offers mine duty drum pulleys using 3/8" or 1/2" two piece rolled rims which are hydraulically clamped around end discs. Center discs are inserted and the two half-shells are triple-pass submerged arc welded to the 1" or 1-1/4" end discs. The seam created by using each half shell is then ground to a radius with our linear bearing guided seam finisher.
