1. To adjust the opening of the clamp, remove the pin (18).
2. Slide the mobile flanges (4) over the fixed flanges (3) to the desired position.
3. Put the pin (18) back.
§ The plate or piece to be lifted must always be driven home into the throat of the clamp.
§ Never lift greasy or oily pieces.
§ Do not use the automatic gripping mechanism when handling fragile loads.
§ For safety's sake, ensure clamps are always unlocked (cam closed) when not in use.
Never lift more than one plate at a time.
§
§ Apply the down gradation if necessary (see sketch).
The minimum weight of lifting load should be equal to 5% of the clamp's WLL (e.g. if clamps WLL
§
is 1000 kg, then minimum weight is 50 kg). This value is given for a clamp in perfect working
order and respecting Tractel Solutions SAS conditions of use and recommendations. Consult
Tractel in case of loads with weight inferior to the minimum recommended value.
§ Lifting clamps are not suitable for creating permanent joints.
Working temperature: -20° to +80°C.
§
Handling accessory to lift I and H-profiled girders, welded-plated assemblies, horizontal plates.
1. Using the lever (8), open the grab fully until the trigger (9) activates.
2. Place the clamp against the plate or girder until the slot is driven home against the flange of the plate or
girder to be lifted.
3. The trigger (9) is released, the cam (6) goes in contact with the plate/ girder, the setting lever (8) swings
around its axis (21)C the safety mechanism is in action and the clamp is ready to perform the lifting
operation.
4. The plate/ girder can be lifted.
5. When the plate/ girder has been moved and laid down, free the clamp by activating the lever (8). The
clamp is now ready to be used again.
§ Use conditions: see sketches at the end of the manual.
§ The plate or piece to be lifted must always be driven home into the throat of the clamp.
§ Surface hardness of pieces to be lifted: maxi. 330 BH and mini. Tensile strength 20 daN/mm².
§ Some stainless steels are particularly abrasive. Inspect for wear of teeth of the cam in this case.
§ Girders or plates to be lifted must not have a coating facilitating slipping (eg: grease, oil, paint...).
§ For safety's sake, ensure clamps are always unlocked (cam closed) when not in use.
§ Never lift more than one plate or girder at a time.
§ Apply the downgradation if necessary (see sketch).
§ The minimum weight of lifting load should be equal to 5% of the clamp's WLL (e.g. if clamps WLL is 1000
kg, then minimum weight is 50 kg). This value is given for a clamp in perfect working order and respecting
Tractel Solutions SAS conditions of use and recommendations. Consult Tractel in case of loads with
weight inferior to the minimum recommended value.
