In the case of clamping products, a clear distinction must be made
between exerting forces and holding capacities. Here are the
essential features:
Exerting or Clamping Force
The“exerting force”of our air toggle clamps is well defined and can be
found on page 11.22. Manually operated clamps present a series of
variables to determine actual exerting force.
These variables are:
(a) the force exerted on the handle by the operator;
(b) the point on the handle where this force is applied;
(c) the mechanical advantage in the linkage; and
(d) the point on the work holding bar where the force will be
measured.As a general rule, the mechanical advantage available
