Allowable load for clamp arm end
Refer to the graph on front matter 6 for parts weight of the arm.
Note) The value shows parts weight only, it does not include arm
weight.
Series
CKZ3T
Use the clamp arm in the catalog.
The length of the clamp arm “L” should be the length
given below or less.
Allowable load for clamp arm end
Refer to the graph on front matter 6 for parts weight of the arm.
Note) The value shows parts weight only, it does not include arm weight.
Single-side-arm type (R/L)
Use within the allowable arm end load range according to the
distance “L” from the fulcrum to the mounting tool’s center
position and the arm opening angle “
θ
”.
Two-side-arm type (D)
Consider the weight of allowable arm end load according to
the center position “G” of each arm end load (W
1
+ W
2
), the
distance “L” to the fulcrum and the arm opening angle “
θ
”.
Use within the allowable range of (W
1
+ W
2
), in this case.
