Hydraulic saw tensioner with adjustable piston travel

摘要

Hydraulic gang-saw tensioner with a continuous cover strip (4) which is arranged in front of the pistons (2) and by which all saw blades (6) are tensioned with the same tensioning travel. This tensioning travel can be changed by the different thickness of the spacer strip (3). The U-shaped cover strip (4) hermetically seals the pistons (2) and the cylinders to the outside by means of the sealing lips (5). <IMAGE>
