singold gerätetechnik gmbh continues its history of masterful engineering: with the newly developed magnetic holder, its pneumatically operated knockers—tried and tested for decades—can be turned into a Knocker to go in no time at all.
This revolutionary new development from the specialist in magnetic holding force is based on an aluminium plate that combines low weight with robustness. Mounted on this plate via ball joints are two suction cups made of flexible plastic with integrated neodymium magnets. The magnet–suction cup combination flexibly adapts to the shape of the container and compensates for inclines and curvatures. As a result, the Knocker to go is also perfectly suited to rough and contaminated surfaces.
Thanks to their spring suspension, the magnets do not detach despite the high impact force of the pneumatic knocker. To allow the strong holding force to be released without great effort, the mobile knocker is equipped with two mounting handles, which also enable adjustment of the preload of the retaining springs.
The magnetic holder for the Knocker to go is lubricant-free, maintenance-free and wear-free, as the joint bearings feature self-lubricating dry sliding layers. Because particular emphasis was placed on low weight during development and the holder is fitted with two side carrying handles, it is especially easy to transport. This allows it to be used as required on interchangeable containers and at changing locations—including containers where permanent installation is not an option.
The magnetic holder is suitable for the pneumatic knockers K40, K63 and K80.
The history of innovation at singold gerätetechnik gmbh will soon gain another chapter: preparations are under way for a purely electric knocker, which is expected to reach market readiness in 2026.
