Our Products - Balooning Jack

A Ballooning Jack is a specialized hydraulic jack used in prestressing operations to ensure proper seating of wedges in anchorages during the stressing process. At Trinity Hydrotech Private Limited, our ballooning jacks are engineered for precision, safety, and durability, making them an essential tool in achieving reliable and accurate prestressing results.

The ballooning process involves applying a controlled hydraulic force to slightly expand (or “balloon”) the strand at the anchorage point. This ensures that the wedges grip the strand firmly and uniformly, preventing slippage and guaranteeing long-term structural stability.

Key features of our Ballooning Jacks include:

• High accuracy in wedge seating, ensuring maximum load transfer efficiency.

• Robust and compact design suitable for tough site conditions.

• Easy operation and handling, enabling quick integration with prestressing systems.

• Durable hydraulic components for long service life and low maintenance.

• Compatibility with multiple strand sizes, making it versatile for various applications.

Each ballooning jack is rigorously tested at our in-house hydraulic press facility to validate performance under working loads. This ensures that the equipment not only meets but exceeds industry standards for safety and quality.

Widely used in bridges, flyovers, metro rail projects, and high-rise buildings, ballooning jacks play a critical role in achieving secure anchorage, structural reliability, and extended service life of prestressed concrete structures.
