FCD double-acting jack can realize various operation forms such as jacking, pushing, pulling, squeezing, pressing and the like. DZB series ultra-high pressure electric oil pump is used as a power source and is widely used for jacking, installing, debugging, overhauling, underground jacking and other operations of equipment in enterprises such as transportation, railways, bridges, buildings, factories, mines and the like.

Double-acting characteristics: 

（1）Adopt double oil circuits, so the return speed is fast and the working efficiency is high.

（2）It is suitable for jacking or reverse pulling.

（3）Movable saddle protects plunger during operation.

（4）Dustproof ring reduces pollution and prolongs the service life of hydraulic cylinder.

（5）Special guide ring design can withstand deflection load up to 5% of the rated carrying capacity of jack.

（6）Baked paint surface makes corrosion resistance stronger.

（7）It can realize hydraulic self-locking and is suitable for field operation and occasions requiring long-time pressure keeping.

（8）The eccentric load pressure head and special purpose jack can be prepared according to the working conditions.
