CABLE DRIVE ASSEMBLY

摘要

A soot blower (10) incorporating an improved cable drive system. The soot blower (10) includes a housing (12), a travelling carriage (14) including a driven pulley (28) mounted in the housing (12) for reciprocal movement between an extended position and a retracted position, a drive cable (22), a forward tensioning assembly (32), a drive mechanism including a drive pulley (18), a rearward tensioning assembly (24), and a pair of front idler pulleys (34). The drive cable extends from a rear mounting member, around said driven pulley (28), around said drive pulley (18), around said front idler pulleys (34), and again around said driven pulley (28) to a front mounting member (36).
