Prestressed tensioning jacks are the core actuators in post-tensioned prestressed concrete construction. Driven hydraulically, they provide precise and 

powerful tension to steel strands or reinforcing bars, directly imparting the design stress to the concrete structure.

Their core value lies in their superior anchoring performance, stable output accuracy, and broad compatibility with various anchoring systems, making 

them crucial equipment for ensuring the safety and durability of bridges, buildings, and other engineering structures.
