GN 820-NI

Vertical clamps with horizontal base

Bearing pin :
AISI 304 stainless steel.
Features and applications : :
All moving parts are lubricated with special grease. A special feature for GN 820 horizontal clamp is its low profile in clamping position. They are designed in order to prevent operator’s fingers from being caught between the retracting clamping arm and the operator handle (safety distance). The clamping arm is guided on both sides during the forward movement to prevent being affected by possible side thrusts. AISI 304 stainless steel, thanks to its high resistance to corrosion, allows the application of these horizontal clamps with horizontal base on machines and equipment in those sectors where laws or particular hygienic, climatic and environmental factors make it mandatory to use corrosion resistant materials.

GN 831-NI

Hook Clamps

Clamping hook and pin :
AISI 303 stainless steel.
Features and applications :
GN 831 hook clamps are used for the secure holding of flaps, container lids, etc. The clamping action locks securely on the centre and thus they are vibration proof. The self-locking safety catch avoids any undesired releases of the toggle clamp. The load values specified in the here-under table are simply guideline values for a nominal static pulling force which the hook can bear. The pulling force can be adversely affected according to the conditions under which the hook lock clamps are used (vibrations, shock loads, etc).
Stainless steel, thanks to its high resistance to corrosion, allows the application of these hook clamps on machines and equipment in those sectors where laws or particular hygienic, climatic and environmental factors make it mandatory to use corrosion resistant materials.

GN 8330

Hook clamps

Accessories on request :
Spring wire plug (in d2) for safety release lock.
Features and applications :
The outstanding features of hook clamps GN 8330 are superior functionality and design. The integrated spring mechanism holds the locking lever and the clamping hook in the open position and allows effortless operation.
Once the dead center is exceeded, the elasticity of the sheet metal parts will cause the hook clamp to close. In the clamped position, the required drill hole spacing is m2.
With the stroke w of the clamping hook, the elements to be connected can be pulled together during clamping.
The locking mechanism can be secured via the drill hole using spring-loaded plugs. Lead seals may also be attached via d2.
The retaining force given in the table is a guide value for the potentially static tensile stress load acting on the hook clamp. Depending on the conditions of use (e.g. when exposed to vibrations or shock impact), the retaining force may be impaired.
Screws with low-lying flat head must be used to guarantee the proper function. The drill template also allows the assembly using blank rivets.
