5.11 Camber Adjustment

1. The term camber refers to the tilt of the contact

pads as viewed directly from the front or rear of the

attachment.

2. Positive camber, the desired configuration, means

that the contact pads are closer together at the

bottom than the top.

3. Negative camber means that the contact pads are

closer together at the top than at the bottom.

4. To help prevent loss of cartons from the lower tier,

Long Reach recommends a positive camber of 0.0

to 0.50 inch for pads up to 48 inches high and 0.0

to 0.75 inch for pads over 48 inches high.

5. Camber is adjusted by using 1/8 inch spacers, P/N

Y156057, to increase or decrease camber approxi-

mately 1/4 inch on a 48 inch high pad.

6. To increase camber positively, add one or more

spacer(s) between the pad and the lower platen

support. (Figure 5-9)
