Table 14-4: Load Ratings per Flexmount Weigh Module
1
The allowable loads per weigh module (for 250-lb to 10K-lb rated capacities) were determined by using
Allowable Stress Design
as
outlined by American Institute of Steel Construction (AISC) standards. Weigh module component stresses will remain in the elastic
range as long as the allowable loads are not exceeded.
2
Percentages listed in the table (for 20K-lb to 200K-lb rated capacities) are a percent of rated capacity. These values may exceed
the elastic range of some weigh module components.
3
The
side load failure ratings are listed for reference. These values were determined using a test fixture. They represent the side load
at which the load cell mounting bolts shear off the base mounting plate.
4
250-lb to 10K-lb stainless steel side load failure ratings were analytically determined.
