Design features of hydraulic buffers:
Römer Fördertechnik manufactures two hydraulic buffer systems:
1. Hydraulic buffer system PUDZ ( main application crane technic )
2. Hydraulic buffer system Herkules ( main application storage and retrieval machines )
Because of telescopic and totally enclosed design, can both buffer systems be used in any position. At impact the buffer will be inserted into the cylinder. Hydraulic oil inside the cylinder is forced through throttle-holes, sized to take a predetermind impact. Because of resistance within the throttle-holes a hydraulic pressure build-up counteracts the impact mass. After impact gas in a reservoir inside the cylinder will push the plunger back to its original position for further use. Plungers are hard chrom-plated and a multi-layer coat of paint covers the buffer housing to guard against extreme environmental condition.
For further design differences between both buffer systems see article: "Technical information hydraulic buffers".
