Its stability is achieved by the length, geometry and layout of the plunger sleeves within the tamper head, which ensure high wear resistance and a long service life. Each KOBRA »Singlebolt™« is produced to specification and precisely mounted on the tamper head plate. Optimum pressure distribution is achieved by the arrangement of several sleeves on one plunger. The bolting of the tamper shoes enables them to be replaced easily.
Facts & Advantages:
- round plunger sleeves
- standard and spare parts quickly available
- no welds
- short plunger – high stability
KOBRA developed the POWER »Solidline 1™« for products such as slope stabilization blocks. 
POWER »Replace™« was developed for the production of small series products. The frame and insert in the mold bottom are joined by a retainer lock. 
Unlike the other design options of this technology, POWER »Moduline 3™« has a stable one-piece frame, which is bolted onto the insert vertically.
The mold bottom of a POWER »Moduline 2™«- mold is made up of only three components – the insert, the flanges and the wear plates.
POWER »Moduline 1™« comprises of an insert frame joint with tongue and groove, whose vibration behavior on the one hand helps to achieve improved compaction of the concrete, and on the other hand, due to the decoupled insert, it achieves a damping effect, which can reduce wear of the mold.
On the outsides of a POWER »Dynamic 1™« mold there are all round trapeziums, via which the vibrating insert is clamped in bolted frame elements by means of a rubber bearing.
The POWER »Boltline 3™« is used for the production of paver and slab systems from 300mm edge length.
POWER »Basicline 1™« is the classic mold for the production of medium and high paving products.
POWER »Boltline 1™« is used for all high products, such as hollow block, solid block, curb and round curb molds.
The mold bottom of the POWER »Basicline 2™« comprises a precisely machined mold insert made of block material with all-round cavities shaped to hold the flange assemblies including rails.
