Allowable load mass
The allowable load mass changes by the arm opening angle.
Be sure to use the product within the allowable values in the graphs
shown below.
*
The load indicates the total weight of the clamp arm, extension arm, and clamp-
ing block.
*
When the operating time is 1 second.
Calculation procedure of allowable load mass
1. Calculate the distance
L from the fulcrum to the load center of gravity.
2. Check the arm opening angle of the product.
3. Read the allowable load mass from the graph.

Bore size: 63, Arm opening angle: 90
°
,
Distance to the center of gravity: 250 mm
With an arm opening angle of 90° and a 250 mm dis-
tance to the center of gravity, according to the graph,
the maximum allowable load mass becomes 4.0 kg.
