Clamping Force Depending on Hydraulic Pressure and Clamping Arm Length
The achievable clamping force of the CTLB swing clamp depends on the applied hydraulic pressure and the length of the clamping arm used. The following clamping force diagrams provide guidance for selecting and sizing the swing clamp for the respective application.
When selecting the swing clamp, both the required clamping force and the permissible clamping arm length and maximum operating pressure must be taken into account.
Clamping Arm Machining – Adjustment of Lever Position
If required, the clamping arm can be machined according to the dimensions shown below to adjust the lever position.
Note: The required fastening screws for the clamping arm must be sourced separately by the user.
