The original: The world’s first and most powerful pneumatic knocker was developed at singold gerätetechnik gmbh. For over 50 years, singold knockers have been ensuring optimum material flow in the building materials, chemical and food industries and in many other areas of application.

Another ingenious invention of the singold engineers is the flap shutter for the complete emptying of containers and silos. In specialist circles, it is affectionately known as the ”singold flap”.

singold gerätetechnik stands for expertise and experience in material flow solutions and is produced exclusively in Germany – 100% Made in Germany quality. From expert technical advice to top products and customised special designs, you get everything from a single source.

 Pneumatic knockers - The pneumatic knocker is used when high-speed shakers and vibrators with sinusoidal oscillations are not effective.
 Pneumatic distance-knockers - Pneumatic distance knockers are suitable for slowly rotating drums, filling or emptying stations with changing containers and for hot walls.
 Flap shutters - The flap lock is suitable for difficult products in hopper scales, containers, conical screw mixers and many more.

Eliminating flow problems with bulk solids: it can be that simple
Pneumatic Knockers pose a simple but effective approach, just like a hand hammer can get the bulk material flowing again, the Pneumatic Knocker will do the same. Shakers, vibrators, knockers – there are many solutions for free material flow in the bulk goods industry. Yet, finding the right one can sometimes feel more complicated than necessary. singold gerätetechnik gmbh, manufacturer of the world’s first and, therefore, original pneumatic knocker, has a simple but all the more effective approach: whenever a hand hammer can get the bulk material flowing again, the pneumatic knocker will do the same. However, it has significantly more power, requires no human effort and does not dent the silo. The pneumatic knocker was first developed over 50 years ago by company founder Erwin Lüer, and to this day, singold’s pneumatic knockers remain the most powerful on the market. They operate only when needed, minimizing strain on weld seams that can otherwise fatigue under continuous vibration. By activating as required, the pneumatic knocker protects containers, reduces compressed air consumption, and lowers noise levels, contributing

Highly efficient from a distance: the Distance-Knocker QJ from singold When it is not possible to attach a pneumatic knocker directly to a silo,  the pneumatic distance knocker from singold gerätetechnik gmbh offers a solution.
Highly efficient from a distance: the Distance-Knocker QJ from singold
When it is not possible to attach a pneumatic knocker directly to a silo, the pneumatic distance knocker from singold gerätetechnik gmbh offers a solution. It is not always possible to attach a pneumatic knocker directly to a silo, for instance, if the container becomes hot or if it moves. In such cases, the pneumatic distance knocker from singold gerätetechnik gmbh offers a solution. Company founder Erwin Lüer developed it using state-of-the-art engineering. How the Distance-Knocker QJ works The basic concept is the same as that of the traditional pneumatic knocker: spontaneously released compressed air pressure accelerates the impact piston, which is designed as a permanent magnet, after it is released. In contrast to the conventional knocker, the distance knocker’s piston rod strikes a moving impulse part, which is strongly accelerated according to the impulse-momentum theorem and ultimately transfers the energy to the container to be knocked off. This process takes place at such a high speed that the human eye can hardly perceive it. Thanks to the additional impulse part, the Distance-Knocker QJ can be mounted

singold receives ISO 9001:2015 certification
The Deutsche Qualitätsmanagement Akademie GmbH has recently certified singold gerätetechnik GmbH that its quality management complies with the requirements of DIN EN ISO 9001:2015. Requirements for the areas of application development, design, assembly, and sales of devices for material flow optimisation for bulk materials were tested and evaluated. ”We are very pleased that our successful efforts to achieve the highest quality at all business levels have now been confirmed by an external body through the ISO certification,” says Managing Director Oliver Lüer. ”For us, this is an incentive to optimise all processes from development to sales even further.” DIN EN ISO 9001:2015 is the national and international standard for quality management in companies. Companies with this certificate are recognised for their constant efforts to achieve high-quality products and services. Customers of ISO-certified companies can rely on the fact that company processes

Noise protection for pneumatic knockers an important contribution to the health of employees
Noise protection for pneumatic knockers
an important contribution to the health of employees Noise in the workplace not only has serious health consequences, such as damage to the inner ear, headaches, dizziness and even concentration and sleep disorders, but it also affects productivity. In order to keep operational noise levels as low as possible, singold gerätetechnik offers a range of solutions, all of which have been carefully thought out down to the last detail. The pneumatic knocker from singold only knocks when required – this in itself is a contribution to noise protection. But by adding specialised accessories and using a special construction of the pneumatic knocker, sound emissions can be reduced even further. Sound insulation hood The sound insulation hood is put over the pneumatic knocker and, if present, the solenoid control valve, and screwed to the knocker. It is equipped with a rubber bushing for the compressed air hose and a silencer for the rinsing air. Towards the silo wall, a rubber edge protector reduces the sound. It adapts

Thor’s hammer among pneumatic knockers The greatest advantages of pneumatic knockers: particularly powerful, efficient and comparatively light
Thor’s hammer among pneumatic knockers
The greatest advantages of pneumatic knockers: particularly powerful, efficient and comparatively light Impact frequency knockers, interval knockers, shakers and vibrators: they are all used to make bulk materials flow better. Knocking on demand - this is best done with a pneumatic knocker. And no other knocker can produce such a high impact effect with the same size as the pneumatic singold knocker. What are the greatest advantages of pneumatic knockers? Have you ever walked through your plant and seen impact marks on cyclones, bins or silos? In all those cases where the flow of material was restarted with a hammer blow, a pneumatic knocker could have been used more efficiently and with less impact on the material. Unlike shakers, vibrators and even interval knockers, a pneumatic magnetic system knocker can knock on demand - whenever it is needed. This provides the following advantages: * For some products, constant knocking tends to condense the material flow rather than promote it. A single, targeted blow is much more effective here than a vibrator. * Well-directed
