Step 5

Position the clamp(s) to balance the load. Position 
the clamp(s) so the lifting force of the crane is 
directly in line with each clamp’s lifting shackle, 
and the load is evenly distributed (Fig. 33).

Step 6

Engaging the clamp:

VERTICAL LIFT
VERTICAL TURN/LIFT

A.  Attach the clamp to the plate so that it is square with the cam. Ensure the plate is  

 

 

inserted to the full depth of the throat.

B.  Turn the cam screw until the cam just touches the work and the center rings are in

 

contact with plate.

C.  Tighten the screw with the torque limiting handle provided (SAC-1, SAC-3 & SAC-6).

HORIZONTAL LIFT

A.  Place the pad leg under the plate.

    

B.  Lift the clamp slightly so that the pad on the swiveling jaw contacts the plate.

C.  Turn the cam screw until the cam just touches the work and the center rings are in

 

contact with the plate.

WARNING!: Do not side load. Never exceed an angle of 20° from vertical.

WARNING!: Never attach a 

clamp directly to the crane 

hook. Use a sling between 

the crane hook and clamp to 

minimize interference in the 

clamp operation.

WARNING!: Do not over-tighten screw! Screw needs to be hand tight only.
