TELESCOPIC HYDRAULIC CYLINDER / (CTH) – (DOUBLEACTING – MINING EQUIPMENT )

Cylinders design of several concentric located pistons or plungers , moving relative to one by another. The total stroke of the starting point is equal to the sum of the moves of each a plunger or piston compared to an adjacent placements. The telescopic cylinders are used when, in the small length of the shell is necessary to obtain a large stroke of the starting point. The movement starts from the plunger (piston) with the largest diameter. When it reaches the stop, start moving the next, etc. Characteristic of them a stepping change (increase in deployment) the speed of the piston rod in the supplied continuous flow. Double-acting telescopic cylinders are much more complicated and expensive, so be sure their application is sufficiently technical and economically justified. They may also be installed horizontally, when are necessary.
