Martin CMD30063H45 Mine Duty Drum Pulley, 4-1/2 in Dia Shaft, 30 in OD, 63 in W Face, Steel
Martin offers mine duty drum pulleys using a minimum 3/8 in rim (up to 20 in dia), 1/2 in minimum rim on 24 in and larger diameter, 1 in minimum end discs and 3/8 in center discs. Each mine duty drum pulley features a two piece rolled rim, which has been fabricated on either of our flat or custom crowned roll machines. The rims are trimmed and hydraulically seated around the heavy end discs to ensure maximum concentricity. Once the pulley is formed, Martin utilizes a double or triple pass submerged arc weldment to ensure optimum connection of its individual components.
