Clamp arm length andclamping force

Important

02001

The clamp arms transmit the force generatedby the swing cylinder to the workpiece. Clamparms are available in a variety of lengths. After youhave determined the reuired clamp arm length and the clamping force you can select the swingcylinder type and mounting method. The maximum clamp arm length of a given size ofswing clamp is limited. This limitation is due to the bending moment on the plunger. The bending moment applied to the plunger is a function of thereal clamping force and length of the clamp arm.Never exceed the maximum pressure or flow for any given clamp arm length. Excessive weight willlimit flow.The uniue Enerpac swing clamp and patentedclamp arm guarantee the lowest frictional losses and most efficient clamp design available on themarket today. In the chart below you select therequired clamp arm length and clamping force. The use of different length clamp armsrequires reduction in appliedpressure and resulting clamp force. The diagrams on the next page show this relation. 11 Pivoting Tarms

The distribution of the clamparm force is based upon thelength of the T-arm as measured from the pivoting point.
