Chain load range for each gear-motor
Test Chain and Reel Selection
A calibration range is generally targeted between 50% to 80% of the maximum design
load. Use the belt scale’s design information to determine chain requirements.
Example
The next larger chain is the preferred choice to retain the desired percent of maximum
loading. In our example, the calculation is performed at 60%:
166.67 * .60 = 100 kg/m (67.05 lb/ft)
Using the nominal kg/m value of 100, the next larger chain is selected from the chart of
available test chains. The value selected is equivalent to 104 kg/m (70 lb/ft). Test Chain
design size is based at 62.5% belt loading.
The length is based on the idler spacing. The test chain should extend no less than two
fixed idlers beyond each end of the scale mounted idlers. Nominal chain length = (# of
scale 3) * idler spacing:
1 + 3 * 1 = 4m (13 ft.)
