Conveyor technology
Conveying with short strokes
Traditionally, eccentric lifters in Geoskid conveyor technology work with eccentric shafts that are synchronized in their movement by means of toothed belts, chains or linkages. They are driven by a centrally arranged electric motor or a pneumatic cylinder.
Additional guide elements are required to prevent the lifting frame from tilting or jamming. The disadvantages of this technology are the complex basic design and the large amount of space required, which restricts accessibility in the production cell. The cam-type lifter from Expert-Tünkers is a useful addition for strokes in the range of 100 to 300 millimetres. Similar to the classic column lifters, the cam lifters can be arranged flexibly at the front or side of the roller conveyor. The movement profile is determined by the geometry of the cam plate, meaning that there is no need for an additional servo drive with frequency converter.
Both positions, upper and lower, are interlocked with a detent mechanism and ensure operational safety during system downtimes without additional locking elements. The geometry of the cam plate allows the lifting profile to be individually adapted to the conveying task at a constant motor speed. The cam plate lifter is recommended as a robust lifting element for conveying complete floor assemblies or even the entire car body. pb
