Counterweight Cable Length Adjustment Clause Samples

Counterweight Cable Length Adjustment. This adjustment verifies that the two counterweight cables are equally adjusted. Two small 2" x 2" blocks, 1 / 2" thick, are needed for this procedure. Plywood or a stack of thin metal shims may be used. Refer to Figure 8-4. 1. Remove door cover. 2. Place 1 / 2" blocks on each counterweight guide rod bracket and raise the door to lower the coun- terweight onto the blocks. Verify that the weight rests on the 1 / 2" blocks. If the weight rests on the door stop bolts instead, lower the door stop bolts. 3. Raise the door enough to insert the door pins, and pin door to endframe. 4. Adjust the counterbalance cables until the door pins slide in and out without difficulty. After cable adjustment, it is necessary to adjust the COUNTERWEIGHT HARD DOWN STOP.
