Hydraulic bolt tensioner application areas

 

The hydraulic bolt tensioner is used as bolt fastening and disassembly scenarios, and can be widely applied to metallurgical mining, petrochemical, shipbuilding, locomotive manufacturing and other industries. Powered by the hydraulic pump, the bolt is stretched by the elastic amplitude allowed by the material to achieve the purpose of fastening the bolt or dismantling the bolt. Alternatively, it can be installed as a device for applying an axial force as a hydraulic interference connection. It is the ideal bolting equipment for assembly of large and medium-sized mechanical products and equipment maintenance.

 

 

 

Hydraulic bolt tensioning tools have the following advantages:

1. Precision - Bolt load accuracy is extremely high, typically 5% or better. There is no need to consider friction losses and no lubrication. Easy to calculate load transfer and prevent overload.

2. Fast - these tools can be installed and operated quickly.

3. Synchronous stretching – multiple hydraulic bolt tensioners can be hydraulically tightened at the same time.

4. Consistent - Multiple bolts are pre-tensioned at the same time to ensure that the same load is applied to each bolt.

5. Safety - no pinch or reaction problems will occur. The safety of the Ningbo Instruments Mechanics hydraulic stretching system exceeds the industry standard.

6. Versatile - With the adapter kit, a set of fastening tools is available for bolt connections of different sizes.

7. Cost-effectiveness - Combining the above factors, hydraulic bolt tensioners can create practical value for customers.
