ABSTRACT:
Roller-type supporting means is disclosed herein for the lance tube of a long retracting sootblower. An assembly of four rollers is mounted in a cradle structure rockable about an axis transverse to the beam of the sootblower and also swingable about a vertical axis radial to the lance tube axis. The sides of the cradle structure are defined by rocker arms capable of limited independent rocking movement. The rollers are laterally and longitudinally spaced from each other and underengage and support the lance tube. The points of engagement between the rollers and the lance tube lie approximately in a common plane which also includes said transverse axis.
