A complex of tunnels to pass through Prague
Double acting cylinders with lock nut to hold the formwork
As part of the project called “Package of structures of the City Circle Road Myslbekova – Pelc Tyrolka section” in the city of Prague in the Czech Republic, were made a series of tunnels with the aid of formwork for in-situ casting of coatings with articulated structure for the support of the concrete.
At the base of the transport wagon and disarming self-propelled have been used FPT hydraulic cylinder to raise and lower the metal structure .
FPT has supplied 16 cylinders model CRI- GS double-acting lock nut , 100 tons , 100 mm stroke , at a pressure of 700 bar .
The cylinders FPT were employed for the lifting of the formwork , the use of double-acting FPT cylinders allowed to speed up the operations of lowering ensuring the prefect control of movements of the structure. The CRI- GS cylinders double-acting lock nut are the ideal technical solution when it is needed to drive the piston to the end stoke without having the load placed on top of the cylinder , the hydraulic control of the return of the piston speeds up the operation and allows at any time the control of movement of the device.
