(6)When detaching and reassembling supporters, make sure that the chain is kept horizontal. If not, the chain will not move in a straight line. (7) Check that bolts and other hardware are tight when assem- bling and when operating, since they may become loose through operational vibration.
(1) A chain guide is necessary for Cableveyor. An angled steel plate is best. (2) Installation height of the moving bracket (H ’ ) and tolerance for the center of the fixed and moving brackets ( E ) should be set according to the table below. Dimension in inches

(8) Do not put heavy objects or allow people to sit on the chain, as this will result in chain damage.
(9) Note that the chain will sag in its unloaded condition as it is designed to straighten out by its own weight when attached.
(3)Under normal circumstances, lubrication is not necessary. However, for corrosive conditions, a lubricant should be used for protection. (4) Since the TK types do not bend at the bracket chain joint, a minimum extension margin of 1.5 pitches (K on the diagram above) should be adhered to. If this extension margin is difficult to comply with, only one pin should be used in the center of the moving bracket. In addition, if the unit is operated at speeds of 65 ft./min. or more, the location of the moving bracket and fixed bracket should be switched. Two pins should be used with the moving bracket and only one pin (in the center) with the fixed bracket. (5) If the TK split-type supporter must be detached, care should be taken to reassemble the supporter in the same way with the corresponding marks on each half of the supporter properly aligned with each other.
Notes on Fitting Cables or Hoses into the Cableveyor (1) The end of the cable/hose should have an extension margin to insure that no damage occurs between the cable/hose and its attachment. Usually, this amounts to six times the hose diameter.
(2) The minimum cable/hose length necessary is given by the following equation:
L = {(chain pitch • link number) + cable/hose length from chain to its attachment} • 1.015
Note, however, that the hose’s internal pressure causes a slight reduction in hose length. This should be considered when attaching hoses.
