Page 5: Safety
Safety Safety The NTK are intended for generating linear vibrations. Intended use General applications are: loosening, conveying, sorting, compacting, sepa- rating bulk materials and reducing friction. NTK are used for emptying bunkers, as drives for conveyor troughs, sieves and vibrating tables. The NTK are designed for installation in machines and may only be put into operation, if it has been assured that the complete machine complies with the regulations of the machinery directive. - Page 6 Safety Compressed WARNING Compressed air A loosened hose which is under pressure can lead to personal injuries. ➢ Screw the hose lines on carefully. ➢ Check the hose lines and connections after one hour of operation and thereafter regularly (generally monthly). ➢...

Design and function Design and function Design Cover Piston Housing Additional oscillating weight (optional) Air inlet/grommet Chamber A Air outlet/silencer Chamber B The NTK generate linear vibrations. Function The vibration is generated by a freely oscillating, self-reversing piston. Both weights, the piston (5) with an additional oscillating weight (6) on the one hand, the housing (2) and the weight to which it is attached on the other, oscillate in relation to their total weights against each other. -
