HEKO drive chain wheels, type GIA-3, with projecting teeth, are self-cleaning and are ideal for use with sticky and compacting materials as the teeth push out any product
lodged within the chain links. Type GIA-3 has been designed for heavy duty and demanding applications. The replaceable toothed rims and also the outer rim segments are manufactured from alloy steel, teeth with hardened contact areas to reduce wear. These wheels can be used with horizontal shackle and most 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.
