Applications

Lifting and revolving of plates, profiles, fabricated assemblies, steel frames ...

Description

Clamps fitted with a safety spring mechanism for a permanent contact of the cam onto the piece to be
lifted, even when it is being put down. This model also offers an automatic grasping mechanism,
ensuring the clamp's locking when the plate is correctly positioned ie. at the back of the clamp's throat.
The locking lever does not stick out so that the clamp may be used on the bare ground. The chain
enables the revolving and makes the clamp's positioning easier. The corrugated cam only marks one
side of the load.

Functioning

So as to open the clamp's cam, push the locking lever downwards, until the trigger activates ; the lever
remains in a down position. When the load is driven home at the back of the clamp's throat, the trigger
activates and the clamp locks itself automatically.
The corrugated cam penetrates into the load's material. Lifting ensures proportional clamping, thus
avoiding marking the load excessively. To release the clamp, push down the locking lever completely,
until it locks in the open position. The clamp may also be used without the automatism being activated.
To do so, use the manual opening and closing thanks to the lever without bringing it to its limit stop
(trigger not activated). Loads may be grasped horizontally or vertically and revolved in inverse position
(90 or 180°).

Important instructions

 Do not use for fragile loads.
 Using a NK marks the load.
 The plate or piece to be lifted must always be driven home into the throat of the clamp.

Load maximum surface hardness 330 HB and minimum tensile strength 20 daN/ mm².
 Some stainless steels are particularly abrasive ; closely check the condition of the cam's teeth in
this case.

For safety's sa ke, ensure the clamps are always unlocked when not in use (closed cam).
 Never lift more than one plate at a time.
 Apply the downgradation if necessary.
 Working temperature: -20° to +100°C.
