Cincinnati 175 CB - Eccentric Load Capacity; Off-Center Load Capacity

FIGURE 25
ECCENTRIC LOAD CAPACITY
(FRONT-TO-BACK)
Occasionally special forming or punching set -ups are made
which do not have their load centers located on the bed
and ram centerlines. When this condition exists, care must
be taken not to exceed the maximum eccentric
(front-to-back) load capacity of the press brake.

Exceeding the eccentric load capacity could
damage the slides and guides, sink upper bed
bolts into their counterbores causing bed to
become loose, or overstress upper bed and
die clamp bolts causing them to shatter and
possibly causing injury to personnel.
FIGURE 27
NOTE: The above tonnage ratings are for medium speed.
Off-center load ratings in low speed are slightly
lower for some models.
OFF-CENTER LOAD CAPACITY
(LEFT-TO-RIGHT)
Most forming and punching jobs are located on the
centerline of the machine where the full rated machine
capacity is available. When the load is not located at the
center of the machine only a portion of the total capacity is
available as shown in Figure 27.
