32 Chain C/c K2 Flat Bar Type K2 Flat Bar Type 2 Attachment Type ●Flat bar type Flat bar type Using a chain with Attachment, a flat bar is installed on the Attachment on both sides, and the flat bar is the same as the stepin type, or the belt is placed on the flat bar. In order to bring the belt to the chain center, a spacer must be placed between the Attachment and the flat bar. Chain with attachment is used. Flat bar is fitted to attachment at both sides. The flat bar is passed inside the spiral (as with stay pin type) or the belt is put on the flat bar. Spacer must be provided between the attachment and the flat bar so that the belt is located in the chain center. ●Angle channel type Angle channel type This type is used to prevent deflection, such as when the chain cores are large or when the belt receiving rail cannot be installed due to heavy loads. Assembled in the same way as a flat bar. This type is used to prevent deflection in case chain c/c is wide but support rail can not be installed. The same installation procedure as that applied to the flat bar is applied. ●Pipe type The same as the angle type, but it is necessary to crush the pipe to install it in Attachment. In addition, by adopting an EP type in the chain, it is possible to assemble in the same way as a stem type, and it is lightweight and less likely to produce deflection in the width. Similar to angle type. With pipe type, however, it is necessary to crush pipe ends so as to fit to the attachment. If EP type chain is used, the same assembling procedure as that applied to the stay pin type can be applied. In this case the weight is reduced, and the widthwise deflection is suppressed.
