Linear actuator with piston segments
With established solutions such as pneumatic and hydraulic cylinders, whether piston-type or telescopic, the usable, extendable length is determined, among other things, by the height of the housing. Telescopic cylinders suffer from the disadvantage of a segmentally decreasing load capacity as the stroke increases, as well as a changing lifting speed. With push chains, both the relatively large cross-section of the chain and the noise level can be problematic. In all these solutions, the high weight and the necessary dimensions of the housings also complicate handling. In field operations involving heavy loads or during rescues, it is often necessary to cyclically lower the load onto blocks, then place them under the blocks and raise the load again until the target height is reached.This device achieves the goals of a large lifting height with low weight, a compact housing, and high load-bearing capacity through a simple and cost-effective design with piston segments stored in a magazine within the housing. The application areas of this device include lifting, moving, and pulling loads, as well as providing a retractable, load-bearing structure that needs to be lowered again after use due to weather, aesthetic, or space constraints. Examples include flagpoles, barriers, antenna masts, etc. In salvage operations, this device eliminates the otherwise necessary multiple extensions and retractions of a piston and subsequent shimming with wooden blocks.
