HEKO drive wheels with pocket teeth type GTA are renown for their trouble free operating characteristics and long service life. The replaceable toothed rims are manufactured from alloy steel with teeth hardened (contact areas) to reduce wear. These wheels can be used with vertical shackle and other types of attachments. Wheels are supplied with keyway or taper lock bushes, the latter on request. In addition the hubs have holes for spacer bars to
adjust for the correct chain centre distance. Toothed wheels are fitted to eliminate chain slip, usually caused when toothless wheels provide insufficient friction grip, i.e. short shaft centres.
